What happened
The aircraft veered off the paved surface and came to rest in a plowed field located approximately 200 feet beyond the midpoint taxiway turnoff. Evidence on the ground indicated that skid marks from both main landing gear began on the runway roughly 100 feet before the turnoff point. These marks angled toward the exit, leaving the runway surface at an approximate 30-degree angle, which suggested the aircraft was maintaining a high groundspeed during the maneuver.
The investigation
Following the event, Federal Aviation Administration inspectors reviewed the pilot's certification records. They discovered that the biennial flight review, which had been conducted four months prior to the accident, was incomplete in terms of standard training requirements. The record showed only 0.5 hours of flight time with no corresponding logged ground instruction.
Findings
The physical evidence pointed to a loss of directional control or an excessive speed during the turnoff maneuver. The discrepancy in the pilot's recent proficiency check raised questions about the adequacy of their recent training coverage, particularly regarding ground-based knowledge components.
