This December 2009 accident report is provided by the National Transportation Safety Board. Published as an educational tool, it is intended to help pilots learn from the misfortunes of others.
Aircraft: Cessna 172. Injuries: None. Location: Diamond Point, Wash. Aircraft damage: Substantial.
What reportedly happened: The pilot was landing at a non-controlled airport where variable gusty winds were present. While on final, she encountered a right crosswind and then both updrafts and downdrafts as she crossed over a cliff under the flight path.
The touchdown was uneventful but, as the airplane slowed during the landing roll, a crosswind gust from the right lifted the right wing. The left wing hit the runway and the airplane nosed over.
According to the pilot, there was no indication of any problem with the flight control or nosewheel steering systems. She also stated that the winds from the north were unusual for this airport, and that she based her assumptions as to what would happen on the runway on the normal westerly or southeasterly winds.
Probable cause: The pilot’s inadequate compensation for the variable and unfavorable wind conditions.
