What happened
On July 10, 2016, a Piper PA-25-235 (registration PT-OMW) was performing a ferry flight from Guaxupé to Curvelo, Minas Gerais, when it experienced a runway excursion during landing at the Curvelo Aerodrome (SNQV). The pilot performed a visual approach to runway 09 but bypassed the standard traffic pattern, executing a direct approach that resulted in an unstabilized flight path.
Upon touchdown, the aircraft experienced a hard impact on the right landing gear. This initial contact caused the aircraft to bounce, and during the subsequent contact, the right wing and the propeller tip struck the runway surface. The impact caused the aircraft to veer to the right and rotate approximately 180 degrees before coming to a stop in a grassy area adjacent to the runway. The pilot was uninjured, but the aircraft sustained substantial damage to the fuselage, wings, landing gear, engine, and propeller.
The investigation
CENIPA investigators examined the flight history, pilot qualifications, and aircraft maintenance records. The investigation established that the pilot was properly licensed and medically certified, with sufficient experience for the flight type. The weather conditions were favorable for operations, and the aircraft was within weight and balance limits.
However, the investigation revealed that the aircraft's Certificate of Airworthiness was invalid at the time of the accident. The last annual inspection (IAM) had been performed over 13 months and 152 flight hours prior to the occurrence, exceeding the 12-month regulatory limit. Additionally, maintenance logs for the airframe, engine, and propeller were not up to date.
Findings
- The pilot executed a direct approach rather than following the standard traffic pattern, leading to an unstabilized approach.
- The hard touchdown and subsequent loss of control were driven by improper application of flight controls and errors in pilot judgment.
- The aircraft was operating with an expired Certificate of Airworthiness.
- Maintenance documentation for the engine, propeller, and airframe was not current.
