05 Feb 2020 - B737-800, TC-IZK (37742/2796), FF 23 Jan 2009, operated by Pegasus Airlines was written off whilst landing at Istanbul, Sabiha Gocken airport (LTFJ) runway 06 at 15:20Z (18:20L) on 05 Feb 2020.
The aircraft was operating flight PC-2193 from Izmir with 177 passengers and 6 crew on-board. It is reported that 179 people were taken to hospital and 3 fatalities.
The crew were flying an ILS onto runway 06. The last wind check given to them on final was 270/25. Two aircraft before this one had gone around and the airport was preparing for a runway change.
LTFJ 051520Z 29022G37KT 240V330 7000 -TSRA FEW017CB BKN025 BKN070 11/09 Q0992 RESHRA NOSIG=
Mode-S data shows that the aircraft touched down around 1950m (6400ft) after the threshold (LDA 3000m) and overran the runway at approx 60 kts. The aircraft broke through a perimeter wall and broke into 3 sections approx 170m from the stop end of the runway.
A preliminary report was issued on 12 Mar 2020. It stated that The Dutch co-pilot did not understand guidance in Turkish and failed to brake in time. "When the speed indicator showed 57 knots, speed brakes and thrust reversers were turned off and manual braking was turned back on,". "The deceleration when the first manual brake was used at a ground speed of 84 knots was not enough, therefore (the plane) ran off the runway at a speed of 60 knots,". The report also said that audio recordings from the flight showed the pilots panicked over possible damage after the plane was struck by lightning some six minutes before landing.
The "final expert report" is reported to say that:
"The accident was "predictable and preventable". The aircraft had received a lightning strike earlier into the flight causing stress to the captain, who wanted to get the aircraft onto the ground as quickly as possible. The approach to runway 06 became unstable with too high a speed in addition to strong tail wind, tower did not instruct a go around. After touch down the captain disabled automatic brakes and speed brakes when he believed the aircraft had slowed sufficiently, the aircraft did not experience deceleration for about 6 seconds as result before manual braking was applied causing the main wheels to hydroplane. The aircraft crossed the runway end at 57 knots and impacted the airport perimeter wall causing 3 fatalities and 180 injuries. The report also states that the copilot, with 400 hours total flight time, did not call out various deviations (e.g. speed, sinkrate, ...) during the final approach and did not call for a go around. Part of the blame also goes to the tower, who believed the landing was risky but cleared the flight to land and did not instruct a go around. The lack of a runway end safety area contributed to the accident and in particular to the severity of the accident."
