Analysis

The pilot was approaching the runway for landing and stated that the initial touchdown and landing roll were uneventful. After the first 100 ft, the airplane began to pull to the left, and the right main landing gear collapsed. The pilot said that during a postaccident examination of the right main landing gear, he discovered a small nail that had punctured the tire and innertube. An examination of the airplane by a Federal Aviation Administration (FAA) inspector revealed the horizontal stabilizer and empennage had been substantially damaged during the accident sequence. The FAA inspector also confirmed the punctured tire and innertube. Additionally, the FAA inspector discovered nails on the pilot’s hangar floor that were identical to the nail that was found in the airplane’s tire.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s inadequate preflight inspection which resulted in a failure of the right main landing gear tire on landing rollout, a subsequent loss of directional control, and landing gear collapse.

Findings

Personnel issues Preflight inspection - Pilot
Environmental issues Debris/dirt/foreign object - Effect on equipment
