What happened
On April 7, 2006, a Tecnam P92-JS, registration EC-JAV, was performing a routine training flight at Benabarre Aerodrome in Huesca. During the landing phase on runway 28, the aircraft encountered significant crosswind conditions, with winds measured between 200° and 230° at speeds of 10 to 15 knots.
As the aircraft approached the runway, the nose was already deviated 30° to the left of the centerline. Upon touchdown, the contact was abrupt, causing the aircraft to veer sharply to the left. In an attempt to execute a go-around, the pilot applied maximum power; however, the engine torque further increased the leftward deviation. The aircraft briefly lifted off the runway surface, gliding over uneven terrain and scrubland, but the left main landing gear leg eventually broke under the stress. The aircraft came to a stop after the left wing struck the ground. The pilot was uninjured and able to exit the aircraft independently.
The investigation
The investigation examined the aircraft's maintenance records, which were found to be in compliance with all servicing schedules. The investigation also analyzed the meteorological conditions and the pilot's flight maneuvers.
Technical analysis of the wind conditions revealed that the crosswind component was approximately 14 knots, nearly reaching the maximum demonstrated limit of 15 knots specified in the flight manual. The investigation also reviewed the pilot's application of the go-around procedure. It was noted that while the pilot applied maximum power, the flaps were not retracted as required by the manufacturer's instructions for an aborted landing, which resulted in excessive aerodynamic drag.
Findings
- The crosswind component was at the near-maximum limit allowed for landing.
- The aircraft's light weight intensified the weathercock effect, making it difficult to maintain directional control.
- The pilot failed to use standard crosswind landing techniques or attempt to align the aircraft with the runway axis prior to touchdown.
- The go-around maneuver was unsuccessful because the flaps were not retracted after applying power, preventing the aircraft from gaining sufficient lift to clear the terrain.
