Incident Details
A pilot landed a seaplane into an easterly wind and subsequently noticed that the surface wind was greater than forecast. Unable to taxi to the intended beaching location, he decided to return to his original destination. He maneuvered the airplane into the wind and applied takeoff power. The pilot described the takeoff run as "bumpy" and the water conditions as "rough." At rotation speed, the left float separated from the airplane, causing the aircraft to nose into the water. The pilot and passengers were assisted by a nearby vessel, and the airplane sank into 50 feet of water.
Recovery and Examination
Inclement sea and wind conditions prevented recovery of the wreckage for 52 days. After recovery, the wreckage was stored outside for an additional 13 days before being retrieved by a salvage company. Extensive saltwater corrosion made metallurgical examination of the landing gear components impossible. However, no indication of a preexisting mechanical malfunction or failure was found.
Probable Cause
The pilot's decision to attempt a takeoff in rough sea conditions, resulting in damage to the floats and the sinking of the seaplane.
