Landing (descent or approach)

The aircraft, registered 5Y-NJS operated by Westwind Aviation Ltd crashed at Ngong Racecourse. The flight with two onboard was on a private mission to Kisumu, Eldoret and back to Nairobi. The aircraft departed Wilson Airport (HKNW) at 0420Z and landed at Kisumu Airport (HKKI) at 0502Z. It then departed HKKI to HKEL at 1142Z and landed at 1200Z where it picked one passenger. The flight then departed HKEL to HKNW with three onboard at 1247Z with an estimated flight time of 40 minutes. According to the preliminary information obtained from the Captain, the aircraft attained flight level 250 42NM from Eldoret VOR. The flight was then cleared to fly direct to GV VOR by Nairobi Area Control Centre. During descend to flight level 100 they encountered bad weather whereby the wings developed heavy icing. The Captain deployed deicing systems on the wings but the problem persisted. The situation prompted the Captain to request Wilson Control to descend to “Monstry fix” for landing at HKNW which was approved. As the flight continued descending the left engine went off. The Captain requested Wilson Tower for assistance. After 30 seconds, the right engine also went off. The Captain elected to make an emergency landing at Ngong Racecourse. On landing along, the left wing collided with trees and broke-off and separated together with the left engine and the left main landing gear. The turned clockwise through 180° and faced the opposite direction. All three onboard escaped unhurt but the aircraft was destroyed.

On 20 March 2021, a Boeing 737-400F, registered PK-YSF, was being operated by Trigana Air Service on a non-schedule cargo flight from Halim Perdanakusuma International Airport (WIHH), Jakarta, Indonesia with intended destination of Sultan Hasanuddin International Airport (WAAA), South Sulawesi, Indonesia. On board in this flight was two pilots, one engineer and one Flight Operation Officer (FOO). According to the weight and balance sheet, the flight carried 16,672 kgs of general cargo, takeoff fuel of 11,100 kg and the takeoff weight was 60,695 kg (133,835 lbs). The Pilot in Command (PIC) acted as Pilot Flying (PF) and the Second in Command (SIC) acted as Pilot Monitoring (PM). At 0328 UTC (1028 LT), the PM requested clearance to Halim Tower controller (the controller) to pushback and start the engines. At 1031 LT, the PM requested to the controller for taxi clearance. There was no report of aircraft system abnormality prior to the aircraft departure. At 1047 LT, the controller issued clearance to the PK-YSF pilot to enter and to backtrack Runway 24. At 1051 LT, the PM reported ready for departure to the controller. The controller issued takeoff clearance with additional departure clearance that after takeoff, turn left to heading 180° and initially climb to altitude of 3,000 feet. The PM acknowledged the clearance. The takeoff was conducted with reduced takeoff thrust by assumed temperature of 40°C and the aircraft became airborne at 10:52:57 LT. At 1055 LT, the controller advised the pilot to report when established on heading 180°. The PM reported that they were experiencing right engine failure and requested to fly to AL NDB . The controller advised the PM to turn left heading 060° and to climb to 2,500 feet. Furthermore, the controller asked the pilot intention whether to hold over AL NDB or direct for landing approach. The PM replied that they would hold over AL NDB and added the information that no fire was detected. The controller issued clearance to fly to AL NDB at altitude of 2,500 feet. The controller assumed that PK-YSF would return to Halim and advised the Airport Rescue and Fire-Fighting (ARFF) personnel that PK-YSF experienced right engine failure and would return to Halim. At 1058 LT, the controller requested the information of time required for holding over AL NDB and was replied by the PM that holding would require about 15 minutes. Furthermore, the controller requested whether the pilot able to hold at a point about 15 to 20 Nm from AL NDB and was replied by the PM that they did not objection to the proposal. The controller instructed the pilot to maintain outbound heading up to 15 Nm, at altitude of 2,500 feet. This was intended by the controller to manage the departure and arrival aircraft to and from Halim. At 1116 LT, the PM reported that they were ready to turn left for approach. The controller advised the pilot to turn left and to intercept localizer of the Instrument Landing System (ILS) Runway 24. At 1125 LT, the PM reported to the controller that the Runway was in sight. The controller advised that the wind was from 060° at velocity of 6 knots, QNH 1,007 mbs and issued landing clearance. The aircraft touched down on the touchdown zone and shortly after, both wheels of the right main landing gear detached. The controller noticed spark appeared from the aircraft and pressed the crash bell. At 1127 LT, the controller informed pilots of the other aircraft that the runway blocked by the landing aircraft and identified fire on one of the engines. Few seconds later, the PM called the controller whether any fire and was replied by the controller that fire was visible on the left side of the aircraft.

The report describes the accident to C208B type of aircraft, registration 5Y-JKN with two crew on onboard that occurred on Marsabit Hill on 20th March 2021 in which the aircraft crashed killing two crew onboard. The aircraft with 2200lbs fuel onboard was chartered to ferry Marsabit County Officials to a peace keeping mission at Illeret 156 nautical miles North West of Marsabit town. Preliminary information revealed that the aircraft departed Wilson Airport at 08.20am (0520Z) and arrived within the vicinity of Marsabit town at around 10.00a.m (0700Z). It collided with Kofia Mbaya Hill - Marsabit terrain while attempting to approach Marsabit airstrip. The aircraft first impacted the terrain with its nose-wheel and the main landing gears leaving parts of the fuselage and iron box with its content kept in the lower baggage compartment on the sport. It then ballooned and missed a house before it flipped upside down and impacted the ground and came to rest facing opposite direction. It left a trail of aircraft parts along its path before it came to rest. The nosewheel and its assembly separated and fell off and was found next to the house 110m from its first point of impact. There was no fire after impact but all the occupants received fatal injuries.

Following an uneventful flight from Nursultan Nazarbayev Airport on behalf of the National Security Committee of the Republic of Kazakhstan, the crew was approaching Almaty Airport runway 23R in marginal weather conditions with a ceiling at 300 feet and a visibility limited to 5 km in freezing drizzle. On short final, the aircraft struck the ground and crashed 600 metres short of runway, bursting into flames. Two crew members were rescued while four others were killed.
Those killed were:
Major Gabit Esimdaevich Barlykbayev,
Captain Doszhan Galymbekovich Baimuratov,
1st Lt Mukhtar Hadzhimukanovich Sagimbayev,
Sgt Vasilkov Evgeny Borisovich.

The twin engine airplane departed Detroit-Willow Run (Ypsilanti) Airport at 2337LT on March 6 on a cargo service to Akron-Canton Airport, carrying two pilots and a load of various goods. After takeoff, the crew encountered technical problems and declared an emergency. He completed two low passes in front of the tower, apparently due to gear problems. Eventually, the aircraft belly landed at 0008LT and came to rest on runway 05R. Both pilots evacuated safely and the aircraft was damaged beyond repair.

After takeoff from Abuja-Nnamdi Azikiwe Airport, while climbing, the crew informed ATC about an engine failure and was cleared for an immediate return. On final approach to runway 22, the aircraft went out of control and crashed in an open field, bursting into flames. The aircraft was destroyed and all 7 occupants were killed, among them two pilots, four ATOS specialists (Airborne Tactical Observation System) and one technician.

On final approach to Asunción-Silvio Pettirossi Airport, the twin engine aircraft crashed on a parking place and burst into flames. A passenger was seriously injured while seven other occupants were killed.

The pilot was conducting a cross-country flight and was beginning an instrument flight rules approach from the south. Weather conditions at the destination airport included a ceiling between 800 and 1,000 ft and light rime icing conditions in clouds; the pilot was aware of these conditions. Elevated, wooded terrain existed along the final approach course. Radar and automatic dependent surveillance-broadcast data revealed that the airplane crossed the intermediate approach fix at the correct altitude; however, the pilot descended the airplane below the final approach fix altitude about 4 miles before the fix. The airplane continued in a gradual descent until radar contact was lost. No distress calls were received from the airplane before the accident. The airplane crashed on a north-northwesterly heading about 5 miles south of the runway threshold. The elevation at the accident site was about 1,880 ft, which was about 900 ft higher than the airport elevation. Postaccident examination of the airframe, engines, and propellers revealed no evidence of a pre-existing mechanical failure or anomaly that would have precluded normal operation. Because of the weather conditions at the time of the final approach, the pilot likely attempted to fly the airplane under the weather to visually acquire the runway. The terrain along the final approach course would have been obscured in low clouds at the time, resulting in controlled flight into terrain.

The pilot reported that, while descending through clouds and beginning the instrument approach, some ice accumulated on the wings and he actuated the deice boots twice. The pilot saw the deice boots functioning normally on the wings and could not see the tail; however, the elevator began to shake, and he lost elevator control. The pilot applied forward pressure on the yoke and had to trim nose-down to avoid a stall. There were no cockpit caution indications and the pilot had disengaged the autopilot before descent. The airplane descended through the clouds and impacted a tree before coming to rest upright in a grass area. Postaccident examination of the wreckage, including component testing of the deice system, did not reveal any preimpact mechanical malfunctions. The flap jackscrew position suggested that the flaps were likely in transit between 0° and 10° flap extension at the time of impact. Review of radar data revealed that, during the 2 minutes before the accident, the airplane’s groundspeed averaged about 82 knots; or an approximate average airspeed of 94 knots when accounting for the winds aloft. Current weather observations and forecast weather products indicated that the airplane was likely operating in an area where moderate and potentially greater structural icing conditions prevailed, and where there was the potential for the presence of supercooled liquid droplets. Review of the pilot operating handbook for the airplane revealed that the minimum speed for flight in icing conditions was 130 knots indicated airspeed. It is likely that the pilot’s failure to maintain an appropriate speed for flight in icing conditions resulted in insufficient airflow over the ice contaminated elevator and the subsequent loss of elevator control.

The aircraft departed Lusaka Airport on a flight to Mukinge, carrying five crew members and a load of five diesel drums. After touchdown at Mukinge Airfield, the aircraft was unable to stop within the remaining distance. It overran, collided with obstacles and came to rest with its nose and cockpit severely damaged. Both pilots were injured and three other crew members escaped uninjured.
