Weirsdale, FL, USA

Aircraft #1

N71327

BOEING A75N1(PT17)

Analysis

The pilot of the tailwheel-equipped airplane was landing on a turf runway when a gust of wind caused the airplane to drift off the left side of the runway. The airplane traveled down an embankment, struck a tree, and came to rest nose down. The pilot stated that during the landing, the wind was gusting up to 18 knots from varying directions (initially a headwind, then a left crosswind, and then a right crosswind). He further stated that there were no preimpact mechanical malfunctions or failures that would have precluded normal operation. Postaccident examination revealed damage to the wings and right horizontal stabilizer. The recorded wind at an airport located about 10 miles southeast of the accident site about 20 minutes after the accident was from 110 degrees at 10 knots.

Factual Information
