DHC6, Miri Sarawak Malaysia, 2020

Summary

On 7 January 2020, a DHC 6-400 Twin Otter landing at Miri following a visual approach to runway 02 veered off the side of the runway soon after touchdown but encountered no obstructions before coming to a stop on waterlogged grass. The immediate reason for the veer-off was crew failure to ensure the nosewheel steering system, which is not self-centring, was manually centred before landing. However the context for this error was considered to have been poor awareness of the operation of the nosewheel steering system within a wider context of organisational inadequacy in respect of fleet operational safety.

Description

On 7 January 2020, a DHC 6-400 Twin Otter (9M-SSE) being operated by MASwings on a scheduled domestic passenger flight from Lawas to Miri as MH3517 in day VMC with light and variable surface wind reported departed the left side of runway 02 soon after touchdown and came to a stop approximately 40 metres from the edge of the runway. None of the 16 occupants were injured and the aircraft structure was undamaged although once excavated from the mud, the nose wheel was found to have “heavy spot wear and some heavy wear marks” consistent with marks on the runway.
