What happened
The aircraft departed the departure end of the runway while attempting a go-around. During this maneuver, the landing gear collapsed upon impact with the ground. The pilot reported that the brakes failed during the initial landing phase, prompting the decision to initiate a go-around. He noted that he had retracted all flaps but believed one-third flap extension should have been maintained instead.
The investigation
A post-accident examination of the brake system was conducted to determine the cause of the reported failure. The inspection revealed no discrepancies within the mechanical components of the braking system. Records indicated that both brakes had been serviced on the day of the accident, suggesting the system was in a maintained state prior to the flight.
Findings
The primary factors contributing to the incident were the brake failure during landing and the subsequent loss of directional control or speed management that led to the runway excursion. The pilot's decision to retract all flaps during the go-around may have contributed to the aerodynamic conditions, although the mechanical integrity of the brakes was confirmed intact by investigators.
Safety message
Pilots should ensure proper flap configuration during go-around procedures and remain vigilant for brake performance anomalies. Regular pre-flight checks are essential, but mechanical failures can still occur despite recent servicing.
