B737, Singapore Seletar, 2017

Summary

On 16 November 2017, a Boeing 737-700 departing Singapore Seletar was observed by ATC to only become airborne very near the end of the runway and to then climb only very slowly. Ten approach lights were subsequently found to have been impact-damaged by contact with the aircraft. The Investigation found that after the crew had failed to follow procedures requiring them to validate the FMC recalculation of modified takeoff performance data against independent calculations made on their EFBs, takeoff was made with reduced thrust instead of the full thrust required. The modification made was also found not to have been required.

Description

On 16 November 2017, a Boeing 737-700 (VP-CAM) being operated by MyJet Asia on a non-revenue positioning flight from Singapore Seletar to Beijing was observed by the TWR controller to get airborne only at the very end of the 1,836 metre-long runway 03 and then perform an extremely shallow climbout in day VMC. After an inspection was requested by the controller, it was found that 10 approach lights had been damaged. The flight crew were advised but reported everything appeared to be operating normally and decided to continue with the intended flight. After completion of the flight, damage consistent with lighting impact by the left main landing gear wheels was found.

Investigation

The matter was reported to the Transport Safety Investigation Bureau of the Singapore Ministry of Transport by ATC and a Serious Incident Investigation was commenced and both the FDR and CVR were removed from the aircraft. Relevant data were successfully downloaded from the FDR but relevant data on the CVR had been overwritten.
