Skystar Series 6 Y-DPS Owner: David John Penrose Aircraft type: Skystar Kitfox Series 6 : Sylvan Adamson Year of manufacture: 2004 : 5Y - DPS Aircraft serial number: S60004-022 Type of engine: Rotax 912S Date of incident: 5 th February 2006 Time of incident: 0416 hours Location of incident: RWY 14 Wilson Airport Type of flight: Private Number of persons on board: Crew 1Passengers 1 Injuries: Crew Fatal; Passengers Fatal : Aircraft completely destroyed Captain s flying experience: 800 hours (of which 25 were on type) The aircraft, registration 5Y-DPS, a Skystar series 6 was on departure for a flight from Wilson Airport to Mweiga Airstrip. The aircraft called Wilson Air Traffic Control (ATC) Tower for taxi and departure clearances. The aircraft had two persons on board and five hours of fuel endurance. The aircraft took off from runway 14 at 0414 hours. It was seen by ATC to rotate shortly before the intersection of the two runways with the initial climb lengthwise the runway before a right turn was made. During the climb, the pilot reported to ATC that he wanted to land immediately on runway 32. At this time, the succeeding aircraft on runway 14 was already lined up and it was advised to immediately leave the runway in order to give way to the accident aircraft. At 0416 hours, the aircraft crashed short of runway 32 at approximately 200 meters from the threshold and on a heading of approximately 060. 3
The probable cause of this accident was the pilot s decision to turn back and land on the same runway from which he had just taken off. Boeing 777-200ER 5Y-KQS Aircraft type: Boeing 777-200ER (B772) : Boeing Commercial Airplanes Year of manufacture: 2005 : 5Y KQS Aircraft serial number: 33683 Date of registration: 17 th June 2005 Type of engine: Rolls-Royce RB 211 Trent 892-17 Date of incident: 5 th April 2006 Time of incident: 0255 hours Location of incident: Apron 1 at Jomo Kenyatta International Airport between Stand 2 and Stand 3 Type of flight: Public Transport (Passenger) Number of persons on board: Crew 12 Passengers 258 Injuries: Crew None Passengers None : Damage to port wing and starboard winglet of a neighbouring aircraft (F-GTUI) 4
The incident was reported by Kenya Airways personnel at about 0430 hours and on site investigation commenced at about 0530 hours. The aircraft was arriving on a scheduled passenger flight from Amsterdam. It was allocated Apron 1 Stand number 2. There was a Boeing 747 (B744) already parked at the same apron on Stand number 3. As the aircraft taxied to its stand, the left wing struck the right winglet of the B744. The cause of the collision was determined to be the allocation of the two aircraft to adjacent bays whose dimensions could not accommodate the two aircraft at the same time. Contributing to the incident was the lack of recurrent training for the marshalling staff. 5
Cessna T210 5H-MLB Aircraft type Cessna T210 Cessna 5H-MLB Date of accident 15 th may 2006 Time of accident 0758 (utc) 1058hrs (local) Location of accident Wilson Airport Nature of flight Public Transport Number of persons on board 2 Injuries Nil Nose landing collapse The aircraft, operated by Kilwa Air of Mwanza was on a flight to Nairobi, en-route to Migori. The aircraft had been chartered by a mining company based in Mwanza and was to drop two company employees in Migori. One of the employees was picked at Mwanza while the second was to be picked in Nairobi. During landing the aircraft touched down normally and during the ground roll the nose landing gear collapsed. The propellers struck the ground as the pilot struggled to stop the aircraft. The aircraft stopped at the intersection of runway 14 and 07 blocking both the runways. On raising the nose and dismantling the nose gear door, we found the nose gear fractured in multiple locations. Investigation could not determine the cause of the gear failure but the fractures were considered to have been as a result of the incident. 6
Beech Bonanza E33 N42FW AIRCRAFT TYPE Beech Bonanza E33 MANUFACTURER Beech Aircraft AIRCRAFT REGISTRATION N42FW AIRCRAFT SERIAL NUMBER CD-1199 DATE OF REGISTRATION 15/3/2001 TYPE OF ENGINE Continental IO-470-K DATE OF ACCIDENT 19/8/2006 TIME OF ACCIDENT 0440 HRS UTC LOCATION OF ACCIDENT Approx. 5 nm North of Eldoret International Airport NATURE OF FLIGHT Private NUMBER OF PERSONS ON BOARD 02 INJURIES 02 NATURE OF DAMAGE Extensive on engine and firewall. Light damage on wings The aircraft took off from Eldoret International Airport and was airborne at 0443 hrs UTC. The destination was Djibouti. Takeoff was from runway 08. It was reported that the aircraft was seen to stop at least two times during taxi before takeoff. After takeoff the aircraft made a left turn and commenced to set course for Lokichoggio. The pilot reported that the engine thereafter, started to lose power but did not shut down. As the engine lost power, he realized that they would not be able to fly back to the airport as they were losing altitude at the same time. The aircraft made a left turn to avoid the power 7
lines that were in their flight path and almost immediately hit the ground in a flat attitude. It bounced over some uneven ground and the outboard starboard wing tip including the tip tank was torn from the right wing. The aircraft slid onto the wheat farm ahead and settled facing the airport to the South. Residents from the adjacent built up area rushed to the scene and tried to help the occupants who suffered various degree of injury. They were rushed to hospital where they were admitted. The aircraft had been fuelled with normal automobile fuel (mogas). Piper PA34-200T 5H-TWO Aircraft type Piper PA34-200T Piper Aircraft 5H-TWO Aircraft serial number 34-8170030 Date of registration Not available Type of engine TSIO-360-EB & LTSIO-360360-EB Date of accident 21/8/2006 Time of accident 0750 Hrs UTC Location of accident End of runway 07 Wilson Airport Nature of flight Commercial passenger Number of persons on board 04 Injuries None Landing gear, propeller and Starboard wing damaged The aircraft was on a flight from Mwanza to Wilson Airport with three passengers and one pilot on board. The aircraft, type Piper PA-34 was operated by Auric Air of Tanzania. The pilot was given clearance by Air Traffic Control to land on runway 07. As he made his landing, eye witnesses observed that he touched down just before the intersection of runway 07 and 14 and immediately applied brakes. The controller confirmed that smoke was coming from the wheels as the pilot applied the brakes. On observation of the left main landing gear tyre showed 8
marks of heavy braking. As the aircraft rolled down the remaining runway the pilot realised that he would not be able to stop on the runway and opted to veer to the right to avoid coming into contact with the perimeter fence. He then decided to steer his aircraft back onto the runway and attempt to make a 180 turn to backtrack the runway. In doing so the aircraft side slipped on the right main landing gear and broke the gear. The aircraft stopped on the runway at right angles with it. Investigation revealed that the pilot had touched down too far down the runway and therefore had inadequate runway length within which to stop. DHC-8-102 Operator Aircraft type 5Y-STN ALS Ltd. DHC-8-102 DeHavilland Canada 5Y - STN Aircraft serial number 179 Type of engine P&W 120 A Date of incident 23 rd August 2006 Time of incident 0440 hours Location of incident Runway 06 Jomo Kenyatta Airport Type of flight Public Transport Number of persons on board Crew 3 Passengers not recorded Injuries Nil Aircraft suffered tyre damage only Captain s flying experience 1500 hours on type The aircraft was departing Jomo Kenyatta International Airport. During the take off roll and at a speed of approximately 87 knots the flight crew heard a loud 9
bang followed by aircraft instability. The aircraft seemed to be having a right turning tendency. As the right hand turning tendency increased the crew opted to reject the takeoff as the airspeed was below V1. They used reverse thrust as well as left brakes which were still available. As they slowed down the cabin attendant reported to have seen smoke from the tyres, followed by the smell of burning tyres. The aircraft finally came to a rest to the right of the runway after application of emergency brakes. Both the engines were shut down before the aircraft came to a complete stop. The two right main landing gear tyres blew during the incident. There was no other damage or injury. An inspection of the remaining tyres indicated that they were serviceable. Airbus A310-304 VT-EJI Aircraft type Airbus A310-304 Airbus Industries Operator Air India VT-EJI Serial number 413 Type of engine General Electric CF6-80C2A2 Date of accident 28 th August 2006 Time of accident 1520 Hrs Location of accident End of runway 06 JKIA Nairobi Nature of flight Public Transport Persons on board 140 Injuries Nil All tyres burst during rejected take-off The flight, AI-200, aircraft type Airbus A310-304, was due to take-off on a flight from Jomo Kenyatta Airport Nairobi to Mumbai. The crew requested and were given ATC clearance to start the engines and to proceed on the flight level 330. ATC departure clearance was given at 1509 hrs which was duly read back by the crew. The aircraft lined up at 1521 hrs and were cleared to take off at 1523 hrs. The crew duly read back the clearance. The aircraft commenced the take-off roll 10
and as it reached V1 speed, lost power on the number 1 engine. The crew opted to abort the take-off, advising ATC about the aborted take-off at 1524 hrs. They advised tower that they would be exiting the runway via the right, and proceeded to exit via taxiway L. After vacating the runway the aircraft stopped with the tail just inside the runway area. Thereafter, the aircraft could not be moved because all eight tyres had burst and the brakes were binding from the heat generated during the emergency stop. This led to a partial closure of the runway. Cessna 152 5Y-MSJ Aircraft type Cessna 152 Cessna 5Y - MSJ Aircraft serial number 152-84008 Type of engine LYCOMING 0-235- L2C Date of incident 24 th September 2006 Time of incident 0949 hours Location of incident Jamhuri Park Nairobi Type of flight Training Number of persons on board Crew 2 Injuries 2 Minor Aircraft substantially damaged Commander s flying experience 2000 hrs The aircraft took off from Wilson Airport, Nairobi, for a routine training flight to local training area and back to Wilson Airport. On board the aircraft were the flight instructor and a student pilot. The aircraft took off from runway 07 at 0939 hrs and headed for a climb through flight level 63 when the pilot noticed decay in the rate of climb enroute to the local training area. The pilot initiated the emergency procedures before crash landing at the Jamhuri grounds. 11
The aircraft crash landed on a rough field and stopped 9 meters from the point of first impact. The instructor and his student were then rushed to the hospital with minor injuries. The aircraft was substantially damaged as a result of the crash. An engine run in the shop indicated that the engine compression was low in a number of cylinders and was considered to have contributed to the low power generated by the engine during the accident flight. Cessna 208B 5Y-NPD Aircraft type Cessna 208B Cessna Aircraft Corporation 5Y - NPD Aircraft serial number 208B0369 Date of registration 12 TH April 2005 Type of engine PT6A-114A Date of incident 23 rd October 2006 Time of incident 0900 hrs Location of incident Between Lokichoggio and Bunagok South Sudan Type of flight Public Transport Number of persons on board Crew 2 Passengers 1 Injuries Crew None; Passengers None Aircraft substantially damaged Captain s flying experience 6500 hours (of which 900 were on type) The aircraft was on a flight from Lokichoggio Airport in Kenya to Bunagok in South Sudan. Approximately 1.5 hours into the flight, the engine started leaking oil which spilled onto the windscreen of the aircraft, imparing the pilots vision. There was smoke in the cockpit and the pilot declared an emergency. The pilot broadcast their position and then prepared for an emergency landing. The aircraft made a successful emergency landing in an open field nearby. After ascertaining that there would be no fire, the pilot radioed his company from the 12
aircraft and help was sent to evacuate them. They were airlifted by helicopter at about 0940 hrs. A strip investigation in an overhaul shop did not reveal any significant failure to the engine. LET 410/Cessna 208B 5Y-BRU/5Y-SLA Aircraft type LET 410-E9 & C208B LET Company & Cessna Aircraft Corporation 5Y-BRU & 5Y - SLA Aircraft serial number LET 912539 & C208B-0574 Type of engine Walter M601 & Pratt & Whitney PT6A-114A Date of incident 24 th October 2006 Time of incident 0900 hrs Location of incident Kichwa Tembo Airstrip Masai Mara Type of flight Commercial Number of persons on board Crew 2 & 1 respectively Passengers 3 & 9 respectively Injuries Crew None; Passengers None Slight wing tip damage on both aircraft Pilot s flying experience 31 hours (of which 6 were on type) The LET 410 aircraft had dropped and picked passengers at Kichwa Tembo airstrip and was taxiing out when the pilot broadcast her intention to take off as is the procedure. At this time the aircraft was lined up at the end of runway 08 ready for takeoff. The Cessna Caravan aircraft was coming in for a landing from Musiara airstrip and about to line up with the runway for the landing. The pilot of the Cessna aircraft responded to the other pilot indicating his position and that he was lining up with the runway. The LET 410 pilot realized that it was not possible to take off before the other aircraft landed. She however believed that there was adequate space for the landing aircraft to make the landing and to vacate the runway. She did not vacate the runway, as would have been expected but remained parked at the end of the runway. The landing aircraft made a successful landing on runway 26 and as it was vacating the runway, the Cessna pilot released the brakes and started to roll for her take off. There was inadequate space for the two aircraft as positioned and the wing tips touched. 13
Antonov AN-12 9L-LFQ Aircraft type Antonov AN - 12 KIAPO, Ukraine Year of manufacture 1962 9L - LFQ Aircraft serial number SN 2400502 Date of registration 2 nd May 2006 Type of engines Turboprop Date of accident 1 st November 2006 Time of accident 1344 hours Location of accident Lokichoggio Airport Type of flight Public Transport (Cargo) Number of persons on board Crew 6 Passengers 3 Injuries Crew None Passengers None Nose landing gear and front lower fuselage damaged The aircraft was on a flight from Jomo Kenyatta International Airport to Lokichoggio with 6 crew, 3 passengers and cargo on board. The aircraft, Sierra Leone registration 9L LFQ, type Antonov AN - 12, was operated by 748 Air Services Limited. The aircraft departed Jomo Kenyatta International Airport at 1212 hours and arrived Lokichoggio at 1344 hours. On landing the aircraft bounced several times before the nose wheel collapsed. The aircraft came to a stop about 100 meters from the threshold of runway 27. The crew evacuated safely without any injuries. Efforts to clear the runway started immediately. Several light aircraft landed before the runway was cleared. Two aircraft were diverted to Juba. The runway was cleared by 0100 hours and normal flight operations resumed by 0455 hours. The probable cause of the accident was a higher rate of descent than prescribed during landing leading to bouncing. After the first touchdown, the aircraft bounced three times. This, and the fact that the aircraft was at high loading, lead to the failure of the nose gear. 14
Cessna P206E 5Y-AUC Operator Blue Nile East Africa Limited. Aircraft type Cessna P206E Cessna Aircraft Company Year of manufacture 1970 5Y - AUC Aircraft serial number P - 206-00637 Date of registration 10 th February 1986 Type of engine Continental IO - 520A14B Date of accident 9 th November 2006 Time of accident 1540 hours Location of accident Mandera Airstrip Type of flight Public Transport (Passenger) Number of persons on board Crew 1 Passengers 2 Injuries Crew Minor; Passengers None Nose landing gear, propeller and cargo bay damaged Commander s flying experience 2000 hours (of which 150 were on type) The aircraft was on a flight from Wilson Airport to Mandera with two passengers and the pilot on board. The aircraft, type Cessna P206E, was operated by Blue Nile East Africa Limited. The aircraft departed Wilson Airport at 1159 hours and arrived at Mandera at 1535 hours. It was already dark at the time of arrival and Mandera Airstrip has no lighting. The Army Unit stationed at Mandera positioned two lorries to assist the pilot to land the aircraft. The aircraft touched down well but during the landing roll it veered off the runway and ended up in the ditch about 150 meters from the end of the runway. The pilot had minor injuries while the other two occupants were not injured. This incident was caused by the pilot s poor flight planning and his decision to land by night on an aerodrome that did not have lighting. 15
Cessna 182P 5Y-AZR Operator Z. Boskovic Air Charters Limited Aircraft type Cessna 182P Cessna Aircraft Company Year of manufacture 1975 5Y - AZR Aircraft serial number 182-64260 Date of registration 28 th April 1976 Type of engine Continental O-470-S2 Date of accident 12 th November 2006 Time of accident 1146 hours Location of accident Kutis Airstrip, Laikipia Type of flight Public Transport (Passenger) Number of persons on board Crew 1 Passengers 2 Injuries Crew Minor; Passengers None Substantial Commander s flying experience 415.3 hours (of which 57.8 were on type) The aircraft, type Cessna 182P, took off into wind on runway 08 towards higher ground. On board were the pilot and two passengers. At about 100 feet above ground level, the pilot initiated a shallow bank to starboard in the direction away from the high ground. During this maneuver, the aircraft stalled and impacted the ground. There were no injuries and no fire. The aircraft received substantial damage. The probable cause of this accident was the pilot s decision to take off on runway 08/26 towards higher ground instead of runway 18/36. Unfavorable winds around the higher ground were a contributory factor. 16
