Aviation Accident Summary GAA20CA008

Big Flats, NY, USA

Aircraft #1

N4138Z

Piper PA18

Analysis

The pilot reported that, before takeoff from an off-airport grass field, he consulted his mentor on best practices to takeoff and avoid obstacles. During the takeoff roll, he realized that the planned flightpath was "risky," so he "made a ground track deviation." Subsequently, the left wing struck a guy wire and folded back, and the right wing struck another guy wire. The airplane sustained substantial damage to the fuselage and both wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
