Event Description
During initial climb at approximately 300 feet above ground level, smoke began to enter the cockpit area, emanating from the windscreen defroster vent. The pilot decided to return to the airport for an immediate landing on runway 22.
Wind and Landing Sequence
As the pilot flared for landing, a gust of wind lifted the right wing. This caused the left wing to contact the runway surface. The airplane then ground looped, resulting in substantial damage to the left wing rear spar and left elevator.
Recorded winds at the airport around the time of the accident were from 240 degrees at 11 knots, gusting to 14 knots.
Smoke Source
A subsequent inspection revealed that the source of the smoke was two large holes in the muffler. Prior to departure, the pilot had reported that the engine backfired during his magneto check.
