20 Nov 2020 - The Ukrainian NBAAI have published their final report into the runway excursion and nosegear collapse of 737-800, TC-JGZ operated by Turkish Airlines at Odessa on 21 Nov 2019. The Captain (6,094 hours total, 5,608 hours on type) was PF whilst landing in crosswinds onto Runway 16. Wind 090/22G30Kt, V030/090. The crew went around from their first approach due to the approach being unstable and held waiting for the weather conditions to improve. On the second approach the aircraft landed pointing 6 degrees to the left of the runway QDM and veered to the left after touchdown. At 130kts, the PF applied right rudder pedal and nose wheel steering input to turn the nose wheel 78 degrees right causing it to skid and the tyres to fail. The aircraft skidded off the side of the runway and the nose gear collapsed. The aircraft was evacuated. None of the passengers or crew members was injured but the aircraft was written off. |

Flight HistoryOn November 21, 2019, a regular THY2UT flight en-route Istanbul – Odesa at B737-800 aircraft, nationality and registration mark TC-JGZ of the Turkish Airlines, was performed by the aircraft crew consisting of the Pilot-in-Command (PIC), co-pilot and four flight attendants of the aircraft. In fact, the departure from Istanbul Airport was performed at 17:33. The actual aircraft landing took place at 18:55. According to the flight plan, the alternate aerodromes were Istanbul and Chișinău. There were 136 passengers and 2793 kg of luggage on board the aircraft. The PIC was a Pilot Flying, and the co-pilot was a Pilot Monitoring of the aircraft. The pre-flight briefing of the crew, according to its explanations, was carried out before departure from the Istanbul Airport, after which the PIC took the decision to perform the flight. The climb and level flight were performed in the normal mode. The landing approach was performed to the Runway16 with ILS system at a significant crosswind component of variable directions. At the final stage of approaching with ILS to Runway 16, the ATC controller of the aerodrome control tower (ATC Tower) gave the aircraft crew a clearance for landing. The aircraft crew confirmed the controller’s clearance and continued the landing approach. Subsequently, from a height of about 50 meters, the aircraft performed a go-around due to the aircraft non-stabilization before landing. Following the go-around, the aircraft headed to the holding area to wait for favorable values of wind force and direction. At 18:45, the PIC took the decision to carry out a repeated landing approach, reported of that to the ATC controller, who provided ATS in the Odesa Terminal Maneuvering Area (TMA.) At 18:51, the crew re-contacted the Tower controller and received the clearance to land. At 18:55, after touchdown, during the runway run, the aircraft began to deviate to the left and veered off of the runway to the left onto the cleared and graded area. After 550 m run on the soil, the aircraft returned to the runway with its right main landing gear and nose part (while moving on the soil, the nose landing gear collapsed) and came to rest at the distance of 1612 m from the runway entrance threshold. The crew performed an emergency evacuation of passengers from the aircraft. As a result of the accident, the aircraft suffered a significant damage to the nose part of the fuselage and left engine (it has been written off). None of the passengers or crew members was injured. The investigation identified the following causal and contributory factors: Causal Factors: 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..
