Description

Turkish Airlines flight 467, a Boeing 737-800, suffered a runway excursion after landing at Odessa, Ukraine. The aircraft departed Istanbul, Turkey at 17:32 UTC on a scheduled passenger flight to Odessa. At 18:29 the aircraft approached runway 16, but the landing was aborted because the approach was unstabilized. The flight circled and positioned for another landing. The aircraft touched down at 18:55 UTC but drifted to the left and rolled off the side of the runway. After rolling on the ground for about 550 meters the aircraft was steered back on to the runway, but the nose landing gear collapsed. The aircraft stopped at the left edge of the runway with the left-hand main landing gear still off the side of the runway. Causes The cause of the accident, i.e. runway excursion, which caused significant damage to the structural elements of the aircraft B-737-800 TC-JGZ of Turkish Airlines, which took place on 21.11.2019 during landing at Odesa Aerodrome, was failure to maintain the direction of the aircraft movement during the landing run in the conditions of a strong crosswind of variable directions. Contributing Factors: – Use by the crew of the landing approach method using the Touchdown in Crab technique, which is not recommended by FCTM B-737NG document for use on dry runways in the conditions of a strong crosswind; – Untimely and insufficient actions of the crew to maintain the landing run direction; – Presence of a significant cross component of the wind; – Effect of an omnidirectional wind – from cross-headwind to cross-tailwind directions – during the landing run.
