What happened
On December 9, 2010, a 95-B55 aircraft, registration PT-LEU, departed from Vitória (SBVT) bound for Brasília (SBBR). The flight, which included one pilot and four passengers, was initially operating under Visual Flight Rules (VFR) at flight level 065. During the flight, the pilot requested a change to Instrument Flight Rules (IFR) and an ascent to flight level 100.
Upon reaching 8,100 feet, the pilot reported an engine failure and declared an emergency, initiating a descent toward Ipatinga (SBIP). While navigating the area, the pilot identified a closer landing option at Caratinga (SNCT) but opted to continue toward Ipatinga, likely due to the superior infrastructure at that airport. Approximately 25 miles from the destination, the pilot attempted a forced landing in a sloping field near Córrego do Feijoal. The aircraft struck an obstacle and hit the ground, subsequently catching fire. The impact and subsequent fire resulted in four fatalities (the pilot and three passengers) and one serious injury to a passenger.
The investigation
CENIPA investigators examined the wreckage and the aircraft's maintenance history. The investigation focused on the cause of the right engine failure and the pilot's decision-making during the emergency. Technical analysis of the right engine revealed evidence of excessive carbonization in the cylinder heads and the intake manifold, suggesting a fuel-air mixture issue. Tests on the propeller flange indicated a breakage characteristic of low power at the moment of impact. The left engine was found in a feathered position, and subsequent testing showed no mechanical failures. The investigation also considered the pilot's experience level, noting that while qualified for multi-engine IFR operations, the pilot had limited experience specifically with this aircraft type and IFR procedures.
