A Britten-Norman BN-2A-21 Islander, VH-WQA, experienced a serious emergency landing on Moa Island, Torres Strait. The pilot and six passengers were unharmed. The aircraft was diverted to Kubin Airport, east of the island, following engine surges and power loss. The landing resulted in substantial damage, with the tail separating from the fuselage. Contributing factors included fuel starvation, which likely caused the engine power loss. The pilot?s failure to utilize wing tip tanks, as mandated by the service letter, increased the risk of an inadverent fuel tank selection, potentially leading to a more severe landing. The aircraft’s structural design, specifically the lack of an alternative pilot interface for fuel controls and tank quantities, contributed to this risk.A Britten-Norman BN-2A-21 Islander, VH-WQA, experienced a serious emergency landing on Moa Island, Torres Strait.
