What happened
On April 30, 2000, at approximately 02:00, an R44 helicopter, registration PT-YPY, operated by América Air Táxi Aéreo, performed a forced landing in a coffee plantation near Carmo do Paranaíba, Minas Gerais. The flight originated from Araxá, MG, carrying three passengers for a return trip following a rodeo event.
After landing initially in a rodeo arena to drop off passengers, the pilot moved the aircraft to a nearby area to wait. During the subsequent takeoff attempt, the aircraft encountered obstacles including trees, houses, and high-voltage power lines located approximately 20 meters from the takeoff position. As the helicopter attempted to clear these obstacles, it experienced a sudden loss of power and lift, forcing the pilot to execute an emergency landing. The aircraft sustained severe damage to the main rotor and tail cone, but the pilot and all passengers emerged uninjured.
The investigation
CENIPA's investigation focused on the takeoff performance and operational planning. Investigators examined the aircraft's weight and balance, noting that the takeoff weight of 2,431 lb exceeded the maximum allowable takeoff weight of 2,400 lb for the specific altitude (2,900 ft) and temperature (18°C). Furthermore, the weight required for a hover maneuver exceeded the limit by 131.1 lb.
The investigation also reviewed the pilot's credentials, finding that while his commercial license was valid, his IFR rating had expired, which was a regulatory violation for a night flight exceeding 27 NM. The investigation also looked into the organizational structure of the operator, which relied on subcontracted pilots and aircraft, and lacked a robust flight safety culture.
Findings
- Inadequate takeoff planning: The pilot failed to account for the aircraft's performance limitations regarding weight, altitude, and temperature relative to the obstacles ahead.
- Improper takeoff path selection: The chosen takeoff axis required clearing significant obstacles with insufficient power and lift.
- Operational non-compliance: The pilot operated without the necessary local authorizations and performed a night flight without a valid IFR rating.
- Organizational deficiencies: The operator lacked adequate supervision and standardized procedures, creating an environment where regulatory non-compliance was common.
- Human factors: The pilot's decision-making was influenced by financial pressures and anxiety regarding the unsafe conditions encountered during the initial landing in the arena.
