Circumstances:
On approach to Yiral Airport in poor visibility due to fog, the twin engine aircraft descended too low, impacted the surface of the Yirol Lake and crashed about 2 km north of the airfield. The aircraft was destroyed upon impact and four occupants were rescued while 19 others were killed. A day later, one of the survivor died from his injuries. The three survivors are two children and a Italian doctor. The flight was completed on behalf of the Slaver Company based in Ukraine.
Probable cause:
The committee for the investigations of Slav air let410 aircraft registration UR-TWO has finally concluded that the cause of the accident at Yirol Eastern Lake State Republic of South Sudan was caused by a combination of the following factors:
1. Severely bad weather in the morning of the accident.( Not making a decision to return back to Juba or diverting to the nearest airportRumbek).
2. Pilot incompetency and error in setting the altimeter for Yirol airstrip before the crash. (Causing variations in altitude- flying at false altitude actually below the actual flight level).
3. Replacement of a faulty propeller in Pibor and not informing the safety department of the changes and not being given the release document for operations.

Circumstances:
On Tuesday 10 July 2018, at approximately 1439Z, two crew members and 17 passengers took off on a ZS-BRV aircraft for a scenic flight from Wonderboom Aerodrome (FAWB) destined for Pilanesberg Aerodrome (FAPN) when the accident occurred. During take-off, the left engine caught fire, however, the crew continued with the flight. They declared an emergency by broadcasting ‘MAYDAY’ and requesting to return to the departure aerodrome. The crew turned to the right with the intention of returning to the aerodrome. However, the left engine fire intensified, causing severe damage to the left wing rear spar and left aileron system, resulting in the aircraft losing height and the crew losing control of the aircraft and colliding with power lines, prior to crashing into a factory building. The footage taken by one of the passengers using their cellphone showed flames coming from the front top side of the left engine cowling and exhaust area after take-off. The air traffic control (ATC) on duty at the time of the accident confirmed that the left engine had caught fire during take-off and that the crew had requested clearance to return to the aerodrome. The ATC then activated the crash alarm and the aircraft was prioritized for landing. During the accident sequence that followed, one passenger (engineer) occupying the jump seat in the cockpit was fatally injured and 18 others sustained injuries. The investigation revealed that during take-off, the left engine had caught fire and the crew had continued with the flight without securing the left engine as prescribed in the aircraft flight manual (AFM). The crew had then declared an emergency and attempted to return to the aerodrome, however, they lost control of the aircraft and collided with power lines prior to crashing into a factory building. Owned by Rovos Air (part of the South African Rovos Rail Group), the aircraft was donated to the Dutch Museum Aviodrome based in Lelystad and has to be transferred to Europe with a delivery date on 23 July 2018. For this occasion, the aircraft was repaint with full Martin's Air Charter colorscheme. Part of the convoy program to Europe, the airplane was subject to several test flights, carrying engineers, technicians, pilots and also members of the Aviodrome Museum.
Probable cause:
During take-off, the left engine caught fire and the crew continued with the flight without securing the left engine as prescribed in the aircraft flight manual (AFM). The crew declared an emergency and attempted to return to the aerodrome, however, they lost control of the aircraft and collided with power lines prior to crashing into a factory building. The following contributing factors were reported:
- Pre-existing damage to the cylinder No 13 piston and ring pack deformation and, most probably, the cylinder No 7’s fractured exhaust valve head that were not detected during maintenance of the aircraft,
- Substandard maintenance for failing to conduct compression tests on all cylinders during the scheduled maintenance prior to the accident,
- Misdiagnosis of the left engine manifold pressure defect as it was reported twice prior to the accident,
- The crew not aborting take-off at 50 knots prior to reaching V1; manifold pressure fluctuation was observed by the crew at 50 knots and that should have resulted in an aborted take-off,
- Lack of crew resource management; this was evident as the crew ignored using the emergency checklist to respond to the in-flight left engine fire,
- Lack of recency training for both the PF and PM, as well as the LAME,
- Non-compliance to Civil Aviation Regulations by both the crew and the maintenance organisation.

Captain / Total flying hours:
2352
Circumstances:
The aircraft took-off from Kitale Airstrip (HKKT) at 16.05 hours and set course to Jomo Kenyatta International Airport (HKJK) after climbing to FL 110 with ten onboard. Once established, there were slight peripheral variations in groundspeed and track. The aircraft Flight Level was sustained at 110 with some occasional deviations. Aircraft height above ground level (AGL) varied between 1,102 feet and 4,187 feet. One minute before its impact with the cliff, the aircraft was at 11,100 feet or 3,000 feet AGL, 159 knots ground speed, and tracking radial 338 NV. Immediately before radar signal was lost, the elevation of the highest ground level was 12,876 feet, the aircraft altitude was 11,200 feet, the ground speed was 156 knots, and track was radial 339 NV. Information retrieved from the Radar transcript recorded various parameters of the aircraft from 1605hrs up to 1702hrs, the time radar signal was lost. This information was consistent with information extracted from the on-board equipment the ST3400 and the aera GPS. The radar system transmits information including aircraft position in relation to NV VOR, Flight Level or altitude, ground speed, vertical speed and heading. Information retrieved from the GPS captured the last recorded time, date and location as 14:00:52, on 06/05/2018 and elevation 3,555.57 metres. The aircraft impacted the bamboo-covered terrain at an elevation of 3,645 metres at 0.36’56’’S 36 42’44’’ where the wreckage was sited. The aircraft was totally destroyed by impact forces and all 10 occupants were killed.
Probable cause:
The flight crew's inadequate flight planning and the decision to fly instrument flight rules (IFR) at an altitude below the published Minimum Sector Altitude in the Standard Instrument Arrival Chart under instrument meteorological conditions (IMC), and their failure to perform an immediate escape maneuver following TAWS alert, which resulted in controlled flight into terrain (CFIT).
Contributing Factors:
1. Contributing to the accident were the operator's inadequate crew resource management (CRM) training, inadequate procedures for operational control and flight release.
2. Also contributing to the accident was the Kenya Civil Aviation Authority's failure to hold the operator accountable for correcting known operational deficiencies and ensuring compliance with its operational control procedures.
3. There was no requirement for crew to be trained in CFIT avoidance ground training tailored to the company’s operations that need to address current CFIT-avoidance technologies.
4. Use of non-documented procedure and Clearance by the ATC to fly below the published minimum sector altitude.
5. Lack of situational awareness by the radar safety controller while monitoring flights within the radar service section.

Circumstances:
The single engine aircraft departed Kamonia on a special flight to Kamako on behalf of the United Nations Humanitarian Air Service (UNHAS), carrying three passengers and two pilots. During the takeoff roll from runway 34, the pilot-in-command started the rotation but the aircraft encountered difficulties to gain height. The nose gear and the cargo pod impacted an embankment located at the end of the runway and the aircraft flipped over and came to rest upside down. All five occupants escaped with minor injuries and the aircraft was destroyed.
Probable cause:
It was determined that the aircraft failed to gain sufficient speed during the last portion of the runway due to an excessive accumulation of sand on the ground. The pilot-in-command elected to rotate when the aircraft impacted terrain.
The two following factors were identified:
- The pilot's ability to make a timely decision,
- Lack of coordination between the two CRM (standard call out) pilots during takeoff manoeuvres.
