Accident Sequence
During the landing approach, the pilot reported that he had configured the airplane with what he believed was 20 degrees of flaps. While turning onto final approach, he maintained an airspeed of 80 knots and set the power to 15 inches of manifold pressure. As the airplane flew over trees before the runway threshold, the stall warning indicator activated. The pilot responded by applying full power, but the airplane subsequently impacted the runway surface. The impact caused the airplane to bounce, and during the bounce, the right wing struck bushes alongside the runway.
Post-Accident Findings
Following the accident, the pilot examined the airplane and discovered that the flaps were actually in the 30-degree position. He stated that he had never landed the airplane in this configuration before.
Pilot Statement
In his written statement, the pilot provided the account of the events, detailing his flap setting belief, airspeed, power setting, and the unexpected activation of the stall warning. He also noted the discovery of the flap misconfiguration after the accident.
