What happened
The local sightseeing flight departed from Marlboro Airport at approximately 1300 hours. The aircraft completed its circuit and returned to the airport around 1400 hours. Upon entering the downwind leg of the traffic pattern, the pilot maintained a normal approach configuration.
During the flare phase just before touchdown, the aircraft encountered a sudden gust of wind. This disturbance affected the aircraft's stability during the critical landing moment. After the wheels touched down, the pilot applied the brakes to slow the aircraft.
Despite the braking effort, the aircraft continued to roll forward along the runway surface. The deceleration was insufficient to stop the aircraft within the remaining pavement length. Consequently, the aircraft slid off the end of the runway, resulting in a landing overrun event.
