Narrative:
The DHC-2 Beaver seaplane crashed and sank on take-off. All six occupants were rescued.
"The aircraft was on take-off run from Newtown boat club base and was airborne before losing altitude and subsequently force landing into Wailoaloa Bay," the authorities said.

The plane was later towed back to shore.

CONTRIBUTORY CAUSES:
4.1 The following contributory causes were considered during the accident investigation.
4.1.1 The sea state was moderately rough and the Pilot stated during an interview that he was apprehensive about taking off in these conditions.
4.1.2 As the Pilot commenced his takeoff run towards the South West DQ-TAM was calculated by the Operator to be 183 kilograms below the maximum takeoff weight and with its near-capacity cabin payload of passengers and baggage resulted in the aircraft being "top heavy", that is, the aircraft center of gravity being some distance above the surface of the water. a feature of floatplanes where the aircraft fuselage is attached above the floats
4.1.3 Due to the wave height and lines moving from West to East, DQ-TAM would have been rolling back and forth, this being exacerbated by the westerly wind strength of 13 knots and the inertia of the aircraft.
4.1.4 The Aircraft Flight Manual specifies the crosswind takeoff and landing limitation is not more than 10 miles per hour (mph) at 90 degrees for DHC-2 seaplanes. Ten mph is equal to 8.7 knots and with DQ-TAM being subjected to a calculated
crosswind component of 10 knots on the takeoff run, the Aircraft Flight Manual limitation of 8.7 knots was exceeded by 1.3 knots.
4.1.5 By exceeding the 100 hour flying limitation on the 21, 22 and 24 December 2017 in midsummer when ambient ground temperatures can reach 32 degrees centigrade during early afternoon, it is possible that the Pilot may have suffered from a measure of fatigue when the accident occurred.
