What happened
On September 19, 2014, a PA 28-181 departed from Krems Langenlois for a flight to Friesach/Hirt. After approximately 75 minutes of flight, the pilot approached runway 17 at Friesach/Hirt. During the final approach, the pilot configured the aircraft with full flaps (40°) and reduced speed to between 70 and 80 knots.
The aircraft touched down approximately halfway down the runway. Upon application of the brakes, the pilot found that the aircraft was not decelerating sufficiently, likely due to the wet surface of the grass runway. In an attempt to recover, the pilot initiated a go-around, reducing flaps to 25° and applying maximum power. However, the aircraft climbed only about 30 meters before colliding with a cornfield at an altitude of approximately 2 meters. The aircraft came to a stop 75 meters past the threshold of runway 35. The pilot exited the aircraft without injury.
The investigation
The Austrian SUB examined the aircraft, the pilot's credentials, and the environmental conditions at the time of the accident. The investigation reviewed the aircraft's maintenance records, weight and balance, and the meteorological data from nearby stations. The SUB also reconstructed the flight path based on witness statements and physical evidence at the crash site.
Findings
- The aircraft was within its certified weight and center of gravity limits.
- There were no evidence of pre-existing mechanical failures or technical defects in the aircraft.
- The pilot held all necessary and valid licenses and medical certifications.
- The approach was conducted at a speed higher than the limits specified in the pilot's handbook.
- The pilot used an incorrect visual reference point, which resulted in the aircraft touching down approximately 200 meters past the displaced threshold of runway 17.
- The wet condition of the runway surface significantly contributed to the extended landing roll.
- The decision to initiate the go-around maneuver was made too late to prevent the excursion.
