Narrative:After 14 passengers had boarded the float-equipped Twin Otter, the flight was cleared for west bound takeoff by Male Tower. Wind was 230/09 knots. The total length of the east west runway available for takeoff and maneuvering up to the Hulhule sea wall is approximately 1000 meters. The aircraft seemed to accelerate slowly. Approaching the sea wall captain, realising the height of the aircraft, pulled on the controls to clear the obstacle. The aircraft left float struck the sea wall and separated. The left wing then rotated upwards at the pivot point at the trailing edge of wing. The airplane then impacted runway 18. The right hand float was pushed upwards, causing it to strike the no. 2 propeller.

The checklist be amended to repeat vital checks before every stage e.g. taxi, before takeoff, etc. |
Issued: 15-AUG-2004 | To: | 8Q-TMC (2) |
Review the performance of DHC-6 seaplanes, with wipline floats, in all worst possible configurations, critical runways, wind conditions and verify these practically as much as possible, as wipline float was not part of the initial Type certification. |
Issued: 15-AUG-2004 | To: CAD Maldives | 8Q-TMC (3) |
The CAD should re-examine the criteria for the carriage of flight recorders by aircraft, which have in force a certificate of airworthiness in the Transport Category (Passenger) and are certified to carry more than 9 passengers with a view to requiring all aircraft, whether piston or turbine powered, to carry at least a Cockpit Voice Recorder. |
