What happened
On September 30, 2023, a Cessna 185E, registration LV-ASL, was participating in an aerial festival at the Paraná Aeroclub in Entre Ríos, Argentina. After completing its first skydiving mission of the day, the aircraft taxied toward its assigned parking area. During a 90-degree turn, the pilot perceived that the tail of the aircraft was lifting unexpectedly. In an attempt to correct the movement, the pilot reduced engine power; however, the aircraft's right wing and propeller subsequently made contact with the ground. The incident resulted in minor damage to the wing tip and a sudden engine stoppage, though no injuries were reported.
The investigation
The investigation examined the technical status of the aircraft, the meteorological conditions, and the airfield infrastructure. The Cessuna 185E was found to have a valid airworthiness certificate and all maintenance documentation was up to date. Functional checks of the flight controls and braking systems revealed no mechanical malfunctions.
Meteorological data indicated manageable conditions, with winds near 8 knots and no significant weather phenomena. The investigation also focused on the taxiway surface, noting that the aircraft had traveled through an area of uncompacted, plowed soil while moving toward its parking position.
Findings
- The aircraft's mechanical systems, including flight controls and brakes, were fully operational.
- Weather conditions were within safe operational limits.
- The plowed soil on the taxiway surface likely acted as a contributing factor by creating resistance during the turn.
- The pilot's attempt to reduce power was insufficient to prevent the wing and propeller from striking the ground.
- It remains undetermined if the specific application of brakes, power, or elevator control was appropriate for the maneuver.
