Floatplane Involved in Collision with Trees and Boat Following Gust-Induced Control Loss (N5760D)

Big Lake, AK, US

On May 14, 1996, a Piper PA-18-150 (registration N5760D) was involved in an aviation accident near Big Lake, AK. Investigators recorded the probable cause as: the pilot's improper planning/decision, which resulted in his failure (or inability) to maintain clearance from trees after encountering gusty crosswind conditions. The wind condition and close proximity of trees were related factors. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

After changing from wheels to floats, a pilot took off from a creek into a lake. A gust of wind estimated at over 30 knots lifted the right wing, turning the airplane toward trees. The pilot leveled wings but could not avoid collision.

Background

The pilot reported that he had just changed the airplane's main landing gear configuration from wheels to floats. The takeoff was planned from a creek that entered a large lake, heading west.

Takeoff and Initial Climb

As the pilot began the takeoff run, he estimated the wind was from the northwest at 10 to 12 knots. Shortly after becoming airborne, a gust of wind—estimated at 30 knots or more—caused the right wing to lift. This action turned the airplane toward trees that lined the creek bank.

Loss of Control and Collision

The pilot was able to level the airplane's wings, but he could not turn away from the trees. Subsequently, the airplane collided with the trees and a small boat that rested in front of a lakeside home.
