Primary finding
Probable cause
The pilot's inadequate compensation for wind conditions. Factors were the sudden windshift, and the pilot's lack of seaplane certification.
Investigator assessment
Analysis narrative
The experimental seaplane was unable to maintain a climb sufficient to clear trees at the end of the lake when the headwind shifted to a gusty crosswind. The pilot intentionally landed hard onto the water to avoid trees which were located on the shoreline. The floats separated from the airplane at impact. The pilot did not hold a seaplane rating.
Source record
Factual narrative
On July 20, 1997, at 1130 Alaska daylight time, an Avid Flyer float equipped airplane, N4356H, impacted the water during takeoff from Parsons Lake, Alaska, 10 miles northeast of Nikiski, Alaska. The airplane sustained substantial damage. The private certificated pilot and single passenger were uninjured. The experimental airplane was manufactured and operated by Audie D. Goode of Nikiski, Alaska. The flight was conducted under 14 CFR Part 91 as a personal flight, and visual meteorological conditions prevailed at the time of the accident. The pilot stated that after takeoff, the wind shifted from a headwind to a gusting crosswind, and the airplane could not maintain a climb. He stated that he intentionally landed back onto the water when it became apparent he would not clear trees which were located on the shoreline. The airplane landed hard, and both floats separated from the airplane. The cabin doors were unable to be opened, and both occupants exited through the broken Lexan roof. The pilot did not have a seaplane rating. The Alaska State Trooper who responded to the accident site stated that the winds were observed changing direction as he walked around the lake. -
