N73813 – Cessna 172 – 2007-03-10 NTSB Accident Report

On March 10, 2007, a Cessna 172 (N73813) was involved in an incident near Chugiak, AK. All 2 people aboard were uninjured. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this incident to be: The instructor pilot's inadequate supervision of the student while landing, which resulted in an undershoot, and subsequent in-flight collision with snow-covered terrain.

The certificated flight instructor was providing primary flight instruction to the student pilot under Title 14, CFR Part 91, at the time of the accident. The flight instructor reported that while on final approach to land, he inadvertently allowed the student pilot to descend into a snow-covered area, about 40 feet short of the runway threshold. As the airplane's main wheels contacted an area of deep, hard packed snow, the airplane nosed down, and right wing struck the snow-covered terrain, sustaining substantial damage. The instructor noted that there were no preaccident mechanical anomalies with the airplane.

This incident is documented in NTSB report ANC07CA023. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N73813.
