What happened
On May 8, 2022, an ICP Savannah S, registration EI-GHR, was performing a private local flight departing from Craughwell Airfield in County Galway. While on final approach to Runway 16, the pilot was managing the aircraft at a low altitude and reduced power. After crossing the airfield boundary wall at approximately 50 feet, the aircraft encountered turbulence, causing the right wing to drop abruptly.
In an attempt to stabilize the aircraft, the pilot applied flight control inputs and a burst of power. However, these actions resulted in an unintended pitch-up. The pilot attempted to correct the pitch by pushing the stick forward, but a subsequent pull back on the stick led to the nosewheel and propeller striking the ground to the left of the runway. The aircraft subsequently rolled onto its back. Despite the impact, the two occupants were uninjured and were able to exit the aircraft unaided.
The investigation
The AAIU examined the wreckage and the flight conditions at the time of the accident. The investigation confirmed that the aircraft's nosewheel sheared upon impact and the propeller sustained significant damage, with two blades fracturing and separating. The investigation also verified that the aircraft's controls remained functional and that there were no pre-existing mechanical defects reported.
Meteorological data indicated a south-westerly surface wind of 5 to 10 knots, which would have presented a crosswind component within the aircraft's operational limits. The pilot's licenses and medical certificates, as well as the aircraft's permit to fly, were all valid at the time of the occurrence.
Findings
- The sudden drop of the right wing was likely caused by a stall resulting from a high angle of attack during maneuvering or the encounter with turbulence.
- The pilot's corrective actions, including the use of power, led to an unintended pitch-up.
- There was insufficient altitude remaining to complete the necessary recovery maneuvers after the pilot's subsequent control inputs.
