What happened
The accident occurred during the arrival phase of flight when weather conditions included active precipitation. The pilot initiated the approach and subsequently landed the aircraft on a runway that was wet due to the rain.
Post-landing, the pilot reported that the initial approach speed was approximately 15 to 20 knots higher than the recommended target for the specific aircraft type and conditions. This excess speed contributed to the landing dynamics on the contaminated surface.
Immediately after touchdown, the tires encountered hydroplaning conditions. The loss of tire-to-ground friction prevented the braking system from generating sufficient deceleration force. Consequently, the pilot was unable to bring the aircraft to a stop within the remaining length of the runway.
The aircraft continued its forward momentum past the end of the paved surface. It then entered an adjacent area covered in mud. The impact with the soft terrain resulted in structural damage to the airframe.
The investigation
Examination of the event focused on the interaction between the aircraft's landing gear and the runway surface conditions. The primary finding was the occurrence of hydroplaning, which negated braking effectiveness despite the pilot's attempts to stop the aircraft.
The investigation confirmed that the runway was wet at the time of the incident. No mechanical failures of the braking system or flight controls were identified as contributing factors. The damage was consistent with a high-speed departure from the runway end into soft ground.
