What happened
On June 11, 2022, at approximately 18:40 UTC, an Aero Boero 180 RVR, registration LV-MFM, was performing a local pleasure flight departing from Cafayate Aerodrome in Salta, Argentina. After 30 minutes of flight, the aircraft attempted to land on runway 33. During the final deceleration phase, the aircraft drifted from the runway centerline due to the influence of a crosswind. In an attempt to maintain directional control, the pilot applied excessive braking, which induced a pitching moment that caused the propeller blades and the lower engine cowling to strike the asphalt surface.
The impact resulted in significant damage to the propeller, cowling, exhaust system, and the oil filter bowl. The engine suffered an abrupt shutdown following the strike. The pilot, who was the sole occupant, exited the aircraft without injury.
The investigation
Investigators examined the aircraft and interviewed the pilot to determine the sequence of events. The investigation confirmed that there were no mechanical failures regarding the engine, landing gear, or braking systems prior to the impact. Meteorological data indicated a wind direction of approximately 360° at 5 to 10 knots, which contributed to the lateral drift.
Technical analysis focused on the handling characteristics of conventional gear aircraft. Unlike tricycle gear aircraft, conventional gear designs require more precise management of pitch and direction during the landing roll, as the aircraft remains prone to aerodynamic lift and crosswind sensitivity. The investigation reviewed runway markings, which showed a lateral displacement of about nine meters from the initial contact point to the final position.
Findings
- The primary cause of the accident was the excessive application of brakes to correct a runway centerline deviation.
- A crosswind component contributed to the initial loss of directional control.
- The pilot's limited recent experience with conventional gear aircraft may have influenced the decision-making and control inputs during the landing roll.
