Accident Sequence
After touchdown on the initial landing attempt, the pilot aborted the landing and performed a go-around. During the subsequent landing, the left main landing gear collapsed. The airplane then exited the runway and struck runway lights. A post-accident fire ignited when fuel leaking from under the left wing contacted a hot wire from the damaged runway lights.
Pilot Information
The commercial pilot had completed all company training requirements and satisfactorily completed the CFR Part 135 airman competency/proficiency flight check administered by the company check airman, as well as subsequent line checks. The pilot had accumulated 600 flight hours in the accident make and model.
Aircraft Examination
At the last annual inspection, the accumulated airframe time was 15,522.7 hours. Maintenance records did not reveal evidence of any anomalies or uncorrected maintenance defects. Examination of the left main landing gear revealed that the trunnion had fractured as a result of overload. No microscopic anomalies were found in the trunnion material.
