Narrative:
The DHC-6-300 floatplane was taking off from Brennia Kottefaru water aerodrome (KTH) (Kottefaru, Raa Atoll), when it impacted a swell and was pushed into the air.
The aircraft went into a left bank and dropped outside the reef, landing on the left-hand float and settled upright. The left-hand float and the left-hand wingtip were found damaged.
There were no reports of any injuries to any of the passengers or crew members.


Causes / Contributing Factors
The AICC determines that the probable causes of the serious incident were:
1. The PIC delegated the duties of the PF to the FO to perform take-off, although the FO did not meet the company requirements for taking-off from a category C water aerodrome.
2. High swells and rough water conditions prevailed in the take-off area.
3. The aircraft hit a wave and was hurled into the air unexpectedly before reaching take-off speed.
