Aviation Accident Summary GAA19CA159

Pullman, WA, USA

Aircraft #1

N4100Z

Piper PA18

Analysis

The pilot of the tailwheel- and ski-equipped airplane reported that, while landing off airport on a snow-covered ridge, the back of the right ski struck about a 6-inch-tall, firm snow drift. The right ski then pitched forward, the tip dug into the "crusty" snow, and the airplane nosed over. The airplane sustained substantial damage to the fuselage, empennage, and lift strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
