What happened
During the landing phase of flight, the aircraft veered off the runway and impacted a ditch. According to the pilot, an attempt was made to correct a leftward movement, but the aircraft subsequently veered sharply to the right upon touchdown.
The aircraft came to rest approximately 57 feet from the left side of the runway, oriented roughly 180 degrees opposite to runway 30.
The investigation
Examination of the accident site identified two sets of skid marks on the runway and two sets of tire marks through the adjacent grass area preceding the aircraft. Both sets of marks were found to be similar. Investigation of the tires showed that none had flat spotting and all were in good condition.
Mechanical inspection of the aircraft revealed that the brake system operated without anomalies and the steering system linkage was functional up to the nose gear trunnion. The nose landing gear and right main landing gear had collapsed. All components of the landing gear system remained present, and any breakage observed was consistent with impact damage.
