TALKEETNA, AK, USA

Aircraft #1

N74806

Cessna 180

Analysis

The pilot was departing in a tailwheel equipped airplane on runway 36. He reported that during the takeoff roll, there was a left crosswind that varied from a headwind to a tailwind, and the tail of the airplane began to swing to the right. The airplane ground looped to the left, and ran off the left edge of the runway. The right main landing gear strut collapsed, and the right wing struck the ground. The airplane came to rest partially up on its nose and received damage to the right landing gear attach point, the right wing, and propeller. At 1550, an Aviation Routine Weather Report (METAR) at Talkeetna reported the wind was from 245 degrees at 10 kts.

Factual Information

On May 2, 1997, at 1554 Alaska daylight time, a wheel equipped Cessna 180, N74806, crashed during takeoff at the Talkeetna Airport, Talkeetna, Alaska.
