From the Wikipedia article
Turkish Airlines Flight 301 was a passenger flight operated by a Fokker F28-1000 Fellowship of Turkish Airlines that crashed during takeoff at İzmir Cumaovası Airport on 26 January 1974 while en route to Istanbul Yeşilköy Airport, killing 67 of its 73 passengers and crew.
The aircraft spent the night prior to the accident outside in freezing temperatures, causing frost accumulation on the wings, which was unnoticed by the crew before departure. During takeoff, the pilots over-rotated the plane, causing it to stall, which together with the frost caused the aircraft to climb to just 8–10 m before pitching down and veering left, crashing into the ground and subsequently catching fire.
In 1990, it was claimed that the accident was caused by two of the pilots being drunk. Autopsy results confirmed alcohol was found in the blood of the captain and flight engineer, but that it was not the cause of the accident.
Accident
The pilot in command, İlhan Günaydın, completed the pre-flight walk-around and the plane was ready for departure at 07:07 local time (05:07 GMT) to fly to Istanbul. The aircraft taxied to runway 35 and started its roll after receiving clearance from the tower to do so. The aircraft started lifting off after using 3200 ft of the runway and climbed to a maximum altitude of 8–10 m, after which it started banking to the left and pitching down. The left wing made contact with the ground first, followed by the left fuselage belly which struck the 50 cm bank of a drainage ditch located 28 m left of the runway. The impact ruptured the fuel tank located inside the left wing, causing the plane to catch fire. The plane started to break up as the tail section was separated first. The tail section overtook the fuselage and impacted it between the cockpit and the passenger cabin, causing them to disintegrate as well and turning the latter upside down. The nose section travelled further until it hit a stack of empty drums 2–3 m tall and 150 m away from the runway.
Investigation and cause
Investigation
Newly elected Prime Minister Bülent Ecevit's first order in office was for the Minister of Transport to visit the accident scene and start an investigation to determine the cause. The day after the crash, a flight instructor on board as a passenger claimed that the plane rotated too early and stalled as a result. Five different commissions met with Güley on 27 January at Izmir. Güley announced after the meeting that both flight recorders were recovered and sent to Istanbul. The cockpit voice recorder in the aircraft was found to be defective as the device had not recorded anything; investigators were unable to listen to the tape, which only produced a whizzing sound.
On 12 March 1975, Gündüz Sevilgen, a member of the 15th Parliament of Turkey from the National Salvation Party, wrote several questions to the Grand National Assembly of Turkey related to Turkish Airlines, including the causes of accidents. He received a response from the Minister of Transport, Sabahattin Özbek, on 18 March. The response included a short list of causes of all Turkish Airlines crashes to date. The cause for Flight 301 was: "[t]ake off made with an out-of-limit take off angle and icing on the wing causing the plane to crash with a lack of speed."
Final report
The final report was translated to English and released by the International Civil Aviation Organization in 1977. After the crash, some aircraft components were sent to Rolls-Royce and Fokker for examination, which showed no failures with the respective parts. According to the weather reports, it was 0 C with 95% humidity during the night with the plane outside. Investigators determined that these conditions were enough for frost accretion on the wings and elevators, as had happened to another Fokker F28 the following day during similar conditions. This accretion was not noticed by the captain during his walk-around.
The probable cause mentioned in the final report was that "[t]he aircraft stalled on take-off due to over-rotation and frost accretion on the wings." Calculations based on temperature and load showed that the plane would have reached its takeoff speed after 2800 ft of runway. The flight data recorder showed that the plane rotated after a roll of 3200 ft at a speed of 124 kn. The speed increased up to 133 kn, but then dropped back to 124 knots while veering to the left. The investigators attributed this loss of speed to a "more than normal" angle of attack, meaning that the pilots over-rotated the aircraft, causing it to stall. The low altitude of the aircraft made it impossible for the pilots to recover. Had there been no frost accretion, the plane would have taken off safely despite the other factors.
