Flight Conducted Under: Part 91: General Aviation - Personal
Analysis
The pilot reported that, while en route, she diverted due to deteriorating weather at the intended destination. She added that, during landing, a second pilot in the right seat reported a right quartering crosswind and that, during the "transition to the roundout," she observed 65 knots on the airspeed gauge, she heard the stall warning horn, and the airplane developed a high sink rate. She attempted to go around, but the airplane landed hard and veered left. The airplane became airborne again, and the pilot attempted to regain the runway centerline, but the fuselage and wing struck objects on the left side of the runway. She decided a go-around was not possible, so she reduced power and landed the airplane in grass left of the runway.
The airplane sustained substantial damage to the right wing.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
An automated weather observation station located about 3 miles west of the airport reported that, about 2 minutes before the accident, the wind was from 020° at 8 knots and that, about 32 minutes after the accident, the wind was from 020° at 9 knots. The pilot landed the airplane on runway 27.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain a proper descent rate and landing flare during landing with a tailwind, which resulted in a hard landing and a subsequent loss of directional control, runway excursion, and collision with objects.
