Fokker 50

During the takeoff roll on runway 31 at Mohéli-Bandar es Eslam Airport, while at high speed, the crew decided to reject the takeoff procedure and initiated an emergency braking process. Unable to stop on the remaining distance, the airplane overran, contacted bushes and trees, lost its right main gear and came to rest in a wooded area. All 52 occupants were rescued, among them several were injured, some seriously.

The airplane departed Mogadishu-Aden Adde Airport on an humanitarian flight to Eelbarde, carrying four crew members and a load of various aids on behalf of the World Food Program of the United Nations. After landing on a dirt runway, the airplane failed to stop in time and eventually crashed into a house. The captain was killed and the copilot was seriously injured. Both other crew members escaped uninjured and the house was empty at the time of the accident.

Upon landing at Mogadishu-Aden Abdulle Airport runway 05, the airplane went out of control, veered off runway, lost its left wing and crashed upside down, bursting into flames. The fire was quickly extinguished and all 36 occupants evacuated, three passengers suffered minor injuries.

The aircraft departed Mogadishu-Aden Abdulle Airport on a cargo flight to Beledweyne, carrying four crew members and various goods on behalf of the AMISOM, the African Union Mission in Somalia. After takeoff, the crew informed ATC about hydraulic problems and was cleared to return. After touchdown on runway 05, the aircraft went out of control, veered off runway to the right and collided with a concrete wall. Two crew members were slightly injured while both pilots were seriously injured after the cockpit was severely damaged on impact.

On October 11, 2019 at about 0902 Kenya daylight time, a Silverstone Air Services Fokker 27 Mark 050 registration 5Y-IZO experienced runway excursion on takeoff runway 14 at Wilson Airport with 55 occupants onboard (5 crew and 50 passengers). The aircraft was performing a scheduled flight from Wilson airport to Mombasa, Lamu and back to Wilson airport. The aircraft was fueled then the passengers boarded the plane before the normal pre take off procedures which were reported as uneventful as collaborated by the information from the FDR. The Right Hand engine receded the Left Hand engine in startup as depicted by the parameters from the recorders. From engine startup, taxi, lineup runway 14, power up and including the initial stages of ground roll were uneventful. At 06.02.50 GMT, while still on ground roll take off, the LH engine ITT began to fluctuate, dropped from 707.8 to 175.8. The RH ITT remained stable. The other parameters of both engines were stable. Subsequent power down ensued at 06.03.01, IAS dropped from 110.2Knots and the aircraft magnetic heading increased gradually to 144 consistent with the deviation of the aircraft to the right of the runway axis when it left the paved surface of the runway, before colliding with the airport perimeter fence, went through an embankment before coming to rest tilted to the right after the starboard wing made contact with a tree. The passengers were deplaned through the two left hand side front and rear exit doors. Immediately the event occurred, ATS Wilson airport issued a crash alert and Wilson Airport Fire Service (AFS) responded without delay, found the passengers already evacuated from the aircraft and applied foam to the sections of the aircraft with leaking fuel. Runway 14/32 was closed and all inbound and departure traffic made use of the remaining runway. Preliminary information retrieved from the Flight Data Recorder Radar regarding the engine ITT seems to correlate with the flight crew statements regarding the observed fluctuations on the LHS engine ITT.

On April 30, 2016, the aircraft Fokker F27 MK50 registration marks SE-LEZ, operating Air Vallee flight number RVL233, took off from Rimini airport at 06.48 hrs with 18 passengers and 3 crew on board. During the final approach to Catania airport, with the aircraft stabilized on ILS Z RWY 08, the crew noticed that the right and left main landing gear lights were green but the nose landing gear light was amber. The crew informed the ATS (Catania APP) that they were in contact with the problem and informed them of their intention to continue the approach to perform a low pass on the runway followed by a standard missed approach procedure, in order to request a visual verification from the control tower of the actual extension of the nose gear. During the low passage, the control tower informed the crew that the nose gear was not extended despite the opening of the nose gear compartment. After the passage, all lights, including the amber light of the nose landing gear, went off. The aircraft proceeded to the INDAX point to perform a holding at an altitude of 3000 feet as agreed with ATS during which the crew applied the abnormal procedures for nose gear unsafe down after selection and alternate down procedures. Both procedures were unsuccessful and the crew declared an "emergency" informing ATS of their intention to perform a final maneuver (leveled 2G turn). The captain of the flight, who had been PNF up to that moment, took the controls as PF and executed the turn: also in this case without any positive outcome. The crew informed ATS of the situation, stating the number of passengers, the amount of fuel on board and the absence of dangerous goods. The crew decided to follow a VOR procedure for RWY26 followed by a visual approach in order to make a last low passage to check the condition of the nose gear. After this second missed approach, the aircraft was instructed to perform an ILS procedure for RWY 08. Landing took place at 09:34 hrs with the main gear properly extracted and locked, the nose gear in "up" position and the doors open. The following is a sequence of pictures taken from a video of the accident, acquired by ANSV through the Catania airport operator, in which the aircraft is seen landing with the nose landing gear not extended and touching the ground only when it reached the speed necessary to sustain it in the absence of nose landing gear support. After completion of the landing run, with the aircraft remaining in the middle of the runway, the engines were shut down and passengers and crew disembarked without further incident. Some of the passengers were transferred to the airport emergency room and subsequently some of them were sent to hospital for further examination; no passenger was reported to have sustained injuries as a result of the event.
