Overview
A private certificated pilot was executing a left turn from a base leg entry to the final approach course for landing at an airstrip. During the turn, the pilot reported being about 100 feet above ground level (agl) and over the threshold of the airstrip.
Sequence of Events
According to the pilot, when he added engine power to arrest his descent, the engine rpm did not respond for approximately 3 to 4 seconds. Within that time period, the airplane stalled and descended to the ground. The pilot stated that he leveled the wings before runway contact, and the airplane collided with the runway surface in a wings-level attitude.
Aircraft Damage
The main landing gear collapsed upon impact with the runway. The airplane sustained damage to the left wing lift struts, the left wingtip, and the propeller.
