African Pilot’s August edition
The August edition of African Pilot that features all the aviation businesses at Lanseria International Airport that took part in this feature is complete. The August edition has completed its circulation phase and, but you can always download the August edition or any previous edition from 2020 by clicking on the buttons below. Apart from the Lanseria feature, this bumper edition of 174 pages has more than 34 fully illustrated articles published. It has also become abundantly clear that African Pilot is the only South African aviation publication that has being interacting with its clients and readers on a regular basis throughout the COVID-19 lockdown period.
African Pilot has made significant changes to the August edition
Someone once said the only thing that is sure is that things will change. Over the past 19 years that African Pilot has been publishing its monthly aviation magazine, we have been fixated on the printed version. Now that the magazine is being published in the digital format, the font size has increased by 50%, whilst the number of pages has increased to 174 to accommodate the reader’s experience on digital platforms. The fact that readers will be positioned to access the August edition on any device means that the African Pilot will become far more user friendly. This will be the first of a series of enhancements that will culminate in an interactive publication with provision for picture galleries and short videos within the next month. The August 2020 edition will be the first magazine to adopt some of these changes, with others to follow from September onwards.
African Pilot’s September edition
The September edition of African Pilot will feature Avionics and Instrumentation, which is normal since I usually bring the newest developments of the exciting developments announced at AirVenture in Oshkosh each year. However, this year I will have attended several online webinars during the AirVenture week to find out as much as possible about what is to be launched to the aviation world. This edition is nearly complete and it will be entering its circulation phase on 25 August 2020.
The material deadline for the September edition was on Wednesday 19 August 2020, but we can still accommodate late marketing messages.

COVID-19 consolidated regulations summary
OR Tambo international airport excited and geared up to welcome passengers under level 2
The opening of leisure travel under Level 2 is exciting news for OR Tambo International Airport which is ready and standing by to welcome domestic passengers. The airport is ready to facilitate passengers under Level 2 with extensive health and safety measures in place and rigorous monitoring of compliance with regulations.
“Passengers who have not been inside an airport for months will find a range of measures in place that absolutely have to be followed to the letter. We hope that by now the public has grown accustomed to mask-wearing, sanitisation and hand-washing and physical distancing. Once inside the airport you will still be able to buy refreshments and in due course some food outlets may also reopen. We expect other retailers may also begin to reopen their stores now that demand is returning. The measures applied by these stores will be the same as those used in malls and supermarkets.
Airport instrumentation calibration aircraft has arrived
According to all accounts the Ukrainian airport calibration aircraft arrived on Monday evening. This is a King Air 350 registration UR-CWA. We wish the crew well as they proceed with the work of re-calibrating the airports where various approach and landing instruments have already been switched off.

SAAF 15 Squadron performs long distance rescue mission
An Oryx helicopter from 15 Squadron braved serious weather conditions and several hundred kilometres of rough flying did not stop the South Africa Air Force (SAAF) from executing a successful maritime medevac off Port Elizabeth. The medium transport helicopter based at Air Force Base Durban was summoned to airlift a patient with a serious leg injury off the crude oil tanker Babylon on Friday 14 August. Jonathan Kellerman, NSRI (National Sea Rescue Institute) Durban station commander, said: “On Friday, 15 Squadron, NSRI Durban rescue swimmers and Netcare 911 rescue paramedics were activated to evacuate a 36-year-old Indian crewman, suffering a serious injury, off a 330 metre crude oil tanker near Port Elizabeth.”
The Oryx helicopter, accompanied by two NSRI Durban rescue swimmers and two Netcare 911 rescue paramedics, departed AFB Durban with arrangements for refuelling at East London and Port Elizabeth. After refuelling in East London, on arrival at the ship, off Algoa Bay, in calm sea conditions, the rescue swimmers and rescue paramedic were hoisted onto the vessel with a rescue stretcher.
The seriously injured patient with a compound leg fracture, reportedly sustained in a fall, was taken into care from the ship’s medical crew. Secured into a rescue stretcher the patient was hoisted into the helicopter accompanied by a rescue paramedic. The rescuers were hoisted and recovered into the helicopter. He was brought safely aboard the helicopter and delivered to St George’s Hospital for further treatment thanks to good airmanship and winching skills of the flight crew. According to the SAAF, commander Colonel Zungu, co-pilot Major Sandi and flight engineer Flight Sergeant Vuamzonke undertook an exceptional job of rescuing the patient.
On Sunday 9 August, another SAAF Oryx performed a rescue further down the Cape coast when ten hikers from Bainskloof between Ceres and Wellington became trapped on the wrong side of a swollen river. The helicopter, under the command of Major Agenbag with co-pilot Major Strauss and flight engineer, Warrant Officer Usher, performed the rescue in two separate sorties. The first saw two hikers hoisted and landed safely before the aircraft returned for the remaining eight hikers.
USAF C-130J delivers personal protective equipment to South Africa
On Saturday 15 August a United States Air Force C-130J Super Hercules delivered nearly R6 million worth of personal protective equipment (PPE) to the South African National Department of Health (NDoH), which will use it to support the fight against the COVID-9 pandemic in Gauteng, Western Cape, Eastern Cape and KwaZulu Natal. The US Embassy said the equipment that arrived at OR Tambo International Airport comprised of masks, gloves, medical gowns and sanitizing supplies.
The US Embassy said that the US military’s Africa Command (Africom) also announced that is supporting the set-up of handwashing stations in Gauteng, Eastern Cape and KwaZulu Natal, contributing $225 000 (R4 million) to this initiative. This brings the total value of US support toward South Africa’s COVID-19 response to over $46 million (R808 million),
Separately, the US Centres for Disease Control and Prevention (CDC), the US Agency for International Development (USAID) and the US President’s Emergency Plan for AIDS Relief in Africa (PEPFAR) have worked side-by-side with the South African government throughout the COVID-19 response through the provision of ventilators, oxygen supply and related training; lab support and preparedness; community health care worker support as well as water and sanitation projects, the US Embassy noted.
AFRICAN AVIATION NEWS
Impact of COVID-19 on African aviation and economies is worsening
Written by IATA -18 August 2020
The International Air Transport Association (IATA) has released new data indicating that the impact of COVID-19 on Africa’s aviation industry and economies has worsened sharply since the previous assessment in April. Job losses in aviation and related industries could increase by up to 3.5 million. That is more than half of the region’s 6.2 million aviation-related employment and 400 000 more than the previous estimate. Full-year 2020 traffic is expected to plummet by 54% (more than 80 million passenger journeys) compared to 2019. Previous estimate was a fall of 51%. GDP supported by aviation in the region could fall by up to $35 billion. IATA previously estimated a $28 billion decline.
“COVID-19 has devastated African economies and brought air connectivity across the continent to a virtual standstill. And the situation is getting worse. The economic consequences resulting from a disconnected continent are severe. Millions of jobs and livelihoods are at risk in family-run enterprises and large corporations along the entire travel and tourism value chain. For Africa’s economic recovery and future prosperity, it is essential to expedite the safe restart of the industry,” said Muhammad Al Bakri, IATA’s Regional Vice President for Africa and the Middle East.
To minimise the impact on jobs and the broader African economy an accelerated recovery of air transport across the continent is vital. This can be achieved through government action in two priority areas:
1) Harmonising the restart of air transport in Africa
The harmonised adoption of the International Civil Aviation Organization (ICAO) Council’s Aviation Recovery Task Force (CART) Take-off guidance – the global biosafety framework for the safe restart of aviation – is critical for the safe resumption of air transport, IATA said. :To avoid conflicting measures, disruptions and inefficiencies, all countries, including those in Africa, must apply these recommendations consistently and uniformly, without imposing unnecessary border constraints such as quarantines, which deter passengers and suppress the demand for air travel.”
According to ICAO, Rwanda is amongst the first countries in the world to have fully complied with ICAO’s biosecurity recommendations. Barry Kashambo, Regional Director, ESAF speaking on behalf of the ICAO Regional Offices accredited to African States ICAO said: “We recognise the efforts and actions by Rwanda and some other States, to fully implement the provisions of ICAO CART recommendations and Take-off guidance and measures. We encourage all Governments in Africa to prioritize the restart of aviation and to tap into its potential as an enabler to Africa’s economic recovery post COVID-19. Air connectivity is critical to economic and sustainable development and the movement of persons across the continent.”
2) Stepping up efforts to support the industry
Continued financial and regulatory support, particularly financial relief – that does not increase industry debt levels – through direct cash injections, credit or loans and deferrals or discounts on user charges are essential to support airlines over the restart and recovery period.
“We are grateful to the few African governments that have provided relief to aviation so far – Rwanda, Senegal, Côte d’Ivoire, Burkina Faso and recently Cabo Verde. Their actions have helped save thousands of jobs and will enable some airlines to restart and support the wider economies they serve. But the situation is worsening. Continued relief measures are essential to minimize job losses and ensure that connectivity can be restored. We urge African governments and the development institutions who have committed funding to provide it urgently in a structure that does not weaken already stressed airline balance sheets, before it is too late,” said Albakri.
WORLDWIDE ACCIDENTS AND INCIDENTS
Troubled pilot and his daughter die after plane hits tower
The airline transport pilot and his daughter departed in day visual meteorological conditions with the morning sun behind the Piper PA-28R. About 10 minutes after take-off, the airplane hit a charted, 1,793-foot-tall television / radio tower about 200 feet below the apex of the tower, which was near Kaplan, Louisiana. Both the pilot and his daughter died in the crash.
The pilot and his wife were in the process of divorce. The pilot’s wife was very concerned after the pilot and her daughter departed without notice several weeks before the accident. The pilot had become unresponsive to phone calls from his work supervisor and had been making unauthorised purchases with his work credit card before the accident.
On the day before the accident, the pilot’s attorney informed the pilot that a warrant had been issued for his arrest. A direct course from the departure airport to the pilot’s home airport was over five miles south of the tower. Although a surveillance video and witness statements indicated that the tower’s lighting was erratic, the tower was adequately lit and the visibility of the tower was not a factor in the accident.
NTSB preliminary report: Piper PA32RT
On 1 August 2020, a Piper PA-32RT-300T was substantially damaged when it was involved in an accident near Honesdale, Pennsylvania. The pilot and four passengers were not injured. On the day of the accident, the pilot and the passengers were planning to fly from Cherry Ridge Airport (N30), Honesdale, Pennsylvania, to Ocean City Municipal Airport (OXB), Ocean City, Maryland. According to the pilot, prior to take-off from runway 36, he confirmed that the electric fuel boost pump was on, the mixture and propeller controls were full forward. He increased engine power to full throttle with the brakes held, then released the brakes and initiated the take-off with no flaps extended. He noticed the airplane was veering to the left, which did not correct with right rudder input. The veering became worse as the airplane accelerated.
About halfway down the runway, at 70 to 71 knots, which was not yet the rotation speed, the airplane was near the left edge of the runway and he attempted to get airborne by pulling back on the control column. The airplane may have gotten slightly airborne but did not rotate. He felt the tail ‘bump’ and noted the airplane was off the left side of the runway. The airplane subsequently came to rest in grass with the nose landing gear collapsed. Examination of the airplane by a Federal Aviation Administration (FAA) inspector revealed that it was substantially damaged.
NTSB preliminary report: Piper PA25
On 5 August 2020, a Piper PA-25-235 was substantially damaged when it was involved in an accident near Miami, Florida. The commercial pilot was not injured. The pilot stated that he performed a thorough pre-flight inspection and no discrepancies were reported. He departed with a full fuel tank and after take-off threw out the first tow hook but it became draped over the horizontal stabiliser and elevator. He returned for an uneventful landing, secured the airplane and after clearing the tow hook, he inspected the airplane and noted no damage. He contacted tower, taxied to runway 10L, where he performed another engine run-up and departed, successfully throwing out the tow hook.
He remained in the pattern, picked the banner at 1302 and climbed on an easterly heading to 1,300 feet mean sea level (msl). He leaned the mixture, then at the top of the climb he checked the carburettor heat by applying it for 15 to 30 seconds and noted a 100-rpm drop. He removed carburettor heat and according to company tracking data flew in a southeast direction to Haulover Park, then proceeded in a southerly direction. He flew over the Port of Miami at 1,100 feet msl where he checked the carburettor heat a second time, applying it and leaving on for 15 to 30 seconds, again noting a 100-rpm drop. He removed carburettor heat and continued in a southerly direction. When the flight was south of Fisher Island, he made a radio call on the Watson Island Advisory air-to-air frequency that the flight was at 1,100 feet msl, turning to the north, descending to 700 feet msl. He applied carburettor heat before beginning to descend, but before he had time to adjust the throttle control, the engine rpm dropped to between 1,000 and 1,200.
He checked the magnetos, full and mixture were full forward but that did not restore engine power. Aware of the hazards of dropping the banner he made sure no boats were nearby and he dropped it in the water. Company tracking data reflected a slight left turn towards a south easterly direction followed by a right turn to a westerly heading. He maneuverer for a forced landing and when the flight was between 50 and 100 feet, the engine sputtered like it wanted to come back. He was fast at touchdown and collided with a fence during the landing roll. The airplane stopped within 40 to 50 feet of the fence impact. He secured the airplane.
According to the FAA inspector who examined the airplane at the accident site, the pilot landed to the west on a road. About halfway down it, the right wing collided with a chain link fence. The airplane then turned right and went down a slight embankment before coming to rest upright. He confirmed there was no fuel contamination in the fuel tank or airframe fuel strainer and noted only scratches to the propeller blades, though the propeller spinner was damaged. While he and the pilot were present, a company employee started the engine and briefly operated it to idle. During the short duration engine run oil leakage was noted from a damaged oil cooler; the engine was promptly shut down. The airplane was recovered for further examination of the engine and its systems and the fuel system.
WORLD AVIATION NEWS
Phillips 66 plans to transform San Francisco refinery
Phillips 66 announced that it plans to reconfigure its San Francisco Refinery in Rodeo, California, to produce renewable fuels. The plant would no longer produce fuels from crude oil, but instead would make fuels from used cooking oil, fats, greases and soybean oils. The Phillips 66 Rodeo Renewed project would produce 680 million gallons annually of renewable diesel, renewable gasoline and sustainable jet fuel. Combined with the production of renewable fuels from an existing project in development, the plant would produce greater than 800 million gallons a year of renewable fuels, making it the world’s largest facility of its kind.
The project scope includes the construction of pre-treatment units and the repurposing of existing hydrocracking units to enable production of renewable fuels. This capital efficient investment is expected to deliver strong returns through the sale of high value products while lowering the plant’s operating costs.
If approved by Contra Costa County officials and the Bay Area Air Quality Management District, renewable fuels production is expected to begin in early 2024. Once reconfigured, the plant will no longer transport or process crude oil. The plant is expected to employ more than 400 jobs and up to 500 construction jobs, using local union labour, including the Contra Costa County Building and Construction Trades. Phillips 66 also announced plans to shut down the Rodeo Carbon Plant and Santa Maria refining facility in Arroyo Grande, California, in 2023. Associated crude oil pipelines will be taken out of service in phases starting in 2023.
FAA reopens Cherokee spar AD
The FAA has opened up the Piper Cherokee spar corrosion AD for comments again after AOPA pressed for less expensive ways to address the potential problem. The AD, which was initially proposed in November of 2017, will continue to affect more than 11,000 Cherokees and Cherokee Sixes but some alternative methods of compliance suggested by AOPA have been included and the comment period reopened until Sept. 18. The revised AD also includes information from Piper “to add a minimum thickness dimension for the top inboard wing skin and to include procedures for reapplying corrosion preventive compound if removed during the inspection.”
The original AD called for cutting new inspection ports in the wings because the area of the potential corrosion is not easily accessible from existing ports. Among the AMOCs suggested by AOPA is the use of borescopes to look inside the wing through existing holes.
AD: Continental Aerospace Technologies, Inc.
AD 2020-16-11. This AD was prompted by reports of in-flight engine failures due to fractured crossflow cylinder assemblies. This AD requires visual inspection and depending on the results of the inspection, modification or replacement of the crossflow cylinder assembly. The FAA is issuing this AD to address the unsafe condition on these products.
This AD is effective 21 September 2020.
Supplementary Information: The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Continental Aerospace Technologies, Inc. model GTSIO-520-C, GTSIO-520-D, GTSIO-520-H, GTSIO-520-K, GTSIO-520-L, GTSIO-520-M, GTSIO-520-N, IO-550-G, IO-550-N, IO-550-P, IO-550-R, IOF-550-N, IOF-550-P, IOF-550-R, TSIO-520-BE, TSIO-550-A, TSIO-550-B, TSIO-550-C, TSIO-550-E, TSIO-550-G, TSIO-550-K, TSIO-550-N, TSIOF-550-D, TSIOF-550-J, TSIOF-550-K, and TSIOF-550-P reciprocating Avgas engines with a certain cross-flow cylinder assembly installed. The NPRM published in the Federal Register on 17 April 2020 (85 FR 21336). The NPRM was prompted by reports of in-flight engine failures due to fractured crossflow cylinder assemblies. The NPRM proposed to require visual inspection of the crossflow cylinder assembly and depending on the results of the inspection, modification or replacement of the crossflow cylinder assembly. The FAA is issuing this AD to address the unsafe condition on these products.
AD: Aviat Aircraft Inc.
AD 2020-16-06: The FAA is adopting a new airworthiness directive (AD) for all Aviat Aircraft Inc. Models A-1, A-1A, A-1B, A-1C-180 and A-1C-200 airplanes. This AD requires repetitive inspections of the forward horizontal stabiliser support assembly and the rear horizontal stabiliser support tube and reporting information to the FAA. This AD was prompted by field reports of complete failure of both the forward support assembly and the rear support tube due to fatigue. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective 1 September 2020.
Supplementary Information: The FAA received three field reports from Aviat Aircraft Inc. of complete failure of the rear horizontal stabilizer inboard support tube. The first incident, discovered during a scheduled inspection, occurred in 2005 and the second incident, discovered while the airplane was being re-skinned, occurred in 2009. The third incident was discovered during a pre-flight inspection in 2012 and included a complete failure of the forward horizontal stabiliser inboard support assembly. Failure analysis of both parts from the 2012 incident concluded they failed due to fatigue. In addition to these complete failures of the rear support tube, the FAA received two field reports from Aviat Aircraft Inc. of cracks in the rear support tube, discovered during inspections, in 2005 and 2013.
Aviat Aircraft Inc. subsequently issued Service Bulletin No. 28, Revision A, dated 2 April 2015, which requires a one-time inspection of the rear stabiliser inboard support tube in response to the multiple reports of failures and cracks. In addition to the 2012 incident, which involved a failure of both supports, the FAA received two other field reports from Aviat Aircraft Inc. of complete failure of the forward horizontal stabiliser inboard support assembly, one in 2000 and one in 2019. In the first incident, the failure occurred during ground handling after flight. In the second incident the failure was discovered while the aircraft was being placed in a hanger.
Failure of either the forward or rear support transfers loads to the other support, increasing the likelihood that both could fail. This condition, if not addressed, could result in stabiliser departure and loss of airplane control.
WORLD DRONE NEWS
Optionally manned surveillance / attack plane proposed
A start-up aviation company is proposing an optionally manned surveillance and light attack platform that it says can replace such complicated aircraft as the P-3 and P-8. Icarus Aerospace’s TAV (tactical air vehicle) is a clean-sheet design that looks a lot like a cleaned-up OV-10. Although it comes with two seats, it can also be operated as a drone and as such has swarming capability. “We have developed TAV™ to be in alignment with latest international military armed overwatch and persistent presence requirements and challenges,” said spokesman Marko Ivankovic. “The aircraft platform defines a niche of its own and excels in addressing all existing and future daily threats facing our troops, security forces and our world.”
As a manned aircraft, it offers the crew state-of-the-art avionics with “sensor fusion network centric capabilities” and can carry 8,000 pounds of bombs, missiles or torpedoes. It can be used for battlefield management, communication relay, air-to-air refuelling and medevac duties as either a manned or remotely piloted platform. It is powered by two 1,700-horsepower turboprops and has an endurance of 6.5 hours.
PrecisionHawk earns UTM patents
PrecisionHawk has been awarded two patents for technologies it has developed for UTM. The patents, titled ‘Automated Unmanned Air Traffic Control System,’ are designed to enable collision avoidance between drones and manned aircraft. This is achieved by transmitting real-time flight data from drones to a UTM server prior to and while in-flight.
In order to safely fly drones’ long distances, operators must be able to avoid collisions with other drones and manned aircraft. The first patent is for technology that allows drones to send real-time telemetry to flight servers to avoid collisions while in the air. The second patent helps drone operators avoid collisions by transmitting their flight plan to a traffic management server prior to a flight to see if there is a potential for flight conflicts. The traffic management server receives similar data for other drones and manned aircraft. If there is potential for collision, the traffic management server sends an alert to the drone so the operator can adjust the flight plan.
In 2015, the company introduced LATAS, the Low Altitude Tracking and Avoidance System. LATAS was designed to provide flight planning, tracking, and avoidance for every drone in the sky using real-time flight data transmission based on existing worldwide cellular networks. PrecisionHawk researched and developed LATAS to show that integrating drones into the National Airspace (NAS) could be done safely, which would enable broad drone operations.
These new patent awards are the latest in PrecisionHawk’s long history of UAS innovations. The value of drones is on display across industries, including search and rescue, infrastructure inspection and analysis, and delivery of life-saving medicines and essentials. In order to realize the humanitarian and economic benefits of drone technology in a safe and secure manner, a robust, automated UTM system must be in place to handle the expected traffic with remote identification to identify UAS. The manned air traffic control system will not be able to scale to meet the needs of UAS operations and the burgeoning urban air mobility (UAM) industry. PrecisionHawk’s latest patents will contribute to the efforts to bring a safe, secure UAS traffic control system online.
