AAIB investigation to Cessna 402C, Businessliner, VQ-TIN
Wheels up landing, Ambergris Cay Airport, Turks and Caicos Islands, 17 July 2021.
Summary:
The aircraft landed without its landing gear being extended. The landing gear warning horn was found to be unserviceable after the accident. However, while it could not be determined when it failed, it was not tested prior to the flight, as prescribed in the operators’ Normal Procedures checklist. In addition, the Normal Procedures checklist was not used during the flight. Had it been, the pilot may have noticed the landing gear was not down, despite the warning horn not being serviceable.
