Aircraft Crash in Vila Anhanguera After Takeoff from São Paulo-Congonhas (PT-IEE)

Incident Overview and Immediate Sequence of Events After departing runway 17 at São Paulo-Congonhas Airport, the crew received clearance to climb to 5,500 feet while maintaining heading 270. The flight took place in poor weather, with clouds, atmospheric turbulence, and strong winds. At 5,300 feet, the aircraft lost altitude and descended to 4,700 feet, a level it held for 17 seconds before entering an uncontrolled descent. The aircraft struck and destroyed four houses in the Vila Anhanguera district, approximately 5.5 km southwest of the airport. The aircraft and all four houses were destroyed. All seven occupants were killed, and six people on the ground were injured, one of them seriously. ## Official Probable Cause and Contributing Factors The official investigation attributed the accident to poor weather conditions and a sudden, rapid variation in the aircraft’s attitude, speed, and altitude during the initial climb. Investigators concluded that the pilot flying was under stress and believed the artificial horizons had technical problems. In that situation, the pilot likely made inadequate corrections, worsening the abnormal condition. Contributing factors included crew fatigue after more than 15 hours on duty and insufficient rest at Congonhas, which affected decision-making. The desire to return home and distrust of instruments in difficult conditions further compromised pilot performance. Direct contact with passengers, who were in mourning and eager to return to Maringá, added stress. Unfavorable weather and the pilots’ poor assessment of those conditions also contributed. The operators allowed working time beyond limits and failed to ensure adequate rest, and the captain’s recent instrument-flight training was insufficient.
