Piper PA-11 Ground Control Loss at Aeródromo Juárez (LV-YPF)

Incident Overview and Aircraft Details On October 12, 2023, at 19:40 UTC, a Piper PA-11 with registration LV-YPF, owned by Aeroclub Benito Juárez, experienced a loss of control on the ground during the landing phase at Aeródromo Juárez in Buenos Aires Province, Argentina. The aircraft sustained minor damage, and the pilot, who held a Private Pilot License, was uninjured and exited the aircraft independently. ## Operational Context and Pilot Experience The flight was a general aviation training operation that departed at 18:50 UTC. After 50 minutes of visual meteorological conditions, an uncommanded movement during the final landing roll caused the tail to rise, resulting in the propeller striking the terrain. This led to a sudden engine stop and propeller destruction. The pilot had 382.4 total flight hours and 14.2 hours in the type. Notably, the pilot's last flight before the incident was on August 24, 2023, exceeding the 30-day limit for maintaining currency without instructor readaptation as per RAAC Part 61. ## Investigation Findings and Environmental Factors Field investigations ruled out mechanical failures in the braking system and confirmed control continuity. The aircraft was certified and maintained according to the manufacturer's plan. Meteorological data from the National Meteorological Service indicated wind from 200° at 4 knots, 15 km visibility, and no significant phenomena. The accident occurred on runway 18, which was in good condition, with slight crosswind conditions.
