Synopsis
On 26 August 2023 at 16:30 UTC, a Tecnam P92 Echo MKII with registration LV-S135 experienced a landing gear failure while landing at Saladillo Aerodrome in Buenos Aires Province, Argentina. The aircraft, operated privately for a recreational flight, sustained damage to the right main landing gear, right wing, and fuselage. Both the pilot and passenger were uninjured.
Flight History
The aircraft departed Saladillo Aerodrome at 15:50 UTC for a local recreational flight under visual meteorological conditions. After approximately 40 minutes of flight, during landing on runway 18, the right main landing gear failed, causing the aircraft to veer off the runway.
Damage
Examination revealed significant damage to the landing gear assembly, with minor damage to the right wing and fuselage. The right main landing gear failed due to a material fatigue crack originating from a corrosion pit at the pin hole of the landing gear spar.
Injuries
There were no fatalities or injuries. The pilot and passenger both reported no injuries.
Investigation Findings
The investigation conducted by the Junta de Seguridad en el Transporte (JST) determined that the failure resulted from progressive fatigue in the right main landing gear component. The fatigue crack initiated at a corrosion notch in the area where the pin engages the landing gear spar.
Probable Cause
The probable cause was identified as the failure of the right main landing gear component due to material fatigue, originating from a corrosion notch at the pin hole of the right main landing gear spar.
