B733, Singapore Changi Singapore, 2020

Summary

On 28 November 2020, a Boeing 737-300F taxiing for an early morning departure at Singapore Changi crossed an illuminated red stop bar in daylight and entered the active runway triggering an alert which enabled the controller to instruct the aircraft to immediately exit the runway and allow another aircraft already on approach to land. The Investigation found that the flight was the final one of a sequence of six carried out largely overnight as an extended duty predicated on an augmented crew. The context for the crew error was identified as a poorly managed operator subject to insufficient regulatory oversight.

Description

This triggered an alert to the controller who then instructed the aircraft to exit the runway as another aircraft was on approach to land. The subsequent departure was in accordance with further clearances and without further event.

Investigation
