B738, Kuusamo Finland, 2021

Summary

On 1 December 2021, a lightly loaded Boeing 737-800 became airborne near the end of the runway at Kuusamo with only engine run-up thrust set with only the abnormally low climb rate alerting the crew to their error. Serial failure by both pilots to follow relevant normal takeoff procedures followed after the type-experienced First Officer had been surprised when the aircraft began to move because his inexperience in brake use resulted in insufficient brake pressure being applied during the engine run-up. The Captain’s failure to notice the error was associated with allowing himself to be distracted by a non-urgent radio call.

Description

On 1 December 2021, a lightly loaded Boeing 737-800 (G-JZHL) being operated by Jet2.com on an international non-revenue positioning flight from Kuusamo to London Stansted only became airborne in night VMC shortly before the end of the 2,500 metre-long runway and failed to climb normally until the correct thrust setting was applied. Thereafter, the flight was completed without further event. 

Investigation

The event was reported by the aircraft operator to the UK CAA and the UK AAIB. The latter then contacted the Safety Investigation Authority of Finland, which delegated the conduct of the Serious Incident Investigation to the UK as State of the Operator and a Field Investigation was carried out.
