What happened
On March 7, 1998, a Cessna 210L, registration PT-IQX, departed from an unauthorized airstrip in Laranjal do Jari, Pará, for a scheduled cargo flight. The mission involved transporting supplies and diesel to another clandestine landing strip at the Cruzado mining site. The flight was estimated to last approximately one hour.
Following the aircraft's failure to arrive at its destination, search and rescue operations were initiated. Debris, including a wing section and instrument panel components, was discovered by local miners in the bed of the Jari River, approximately 41 nautical miles from Laranjal do Jari. Two days later, search teams located the pilot's body roughly 300 meters from the wreckage. The pilot sustained fatal injuries at the scene, and the aircraft was a total loss.
The investigation
CENIPA investigators examined the circumstances surrounding the flight, noting that the pilot was experienced but was operating with an expired technical qualification. The investigation also revealed that the aircraft's airworthiness certificate and insurance were both expired. Furthermore, the aircraft had been sold, but the change of ownership had not been officially recorded with the Brazilian Aeronautical Registry.
Regarding the aircraft's mechanical state, investigators found that maintenance logs were outdated and there were no records of services performed since April 1996. While weather reports from other pilots in the area indicated a ceiling of 1,300 feet and visibility of 3,000 meters, the investigation could not definitively rule out spatial disorientation or an engine failure. However, the lack of maintenance records led investigators to consider a mechanical malfunction as a primary hypothesis, which may have forced an emergency landing in the rocky, fast-moving riverbed.
Findings
- Deficient Planning: The flight was planned using unauthorized, clandestine airstrips under restrictive conditions.
- Deficient Supervision: The operator allowed the flight to proceed despite the aircraft and pilot being in an irregular regulatory status.
- Flight Indiscipline: The operation was conducted under marginal conditions with an aircraft and pilot lacking valid documentation.
- Maintenance Uncertainty: The lack of documented maintenance and the expired airworthiness certificate suggested a high risk of mechanical failure.
- Operational Risks: The use of uncertified landing strips and the practice of flying at low altitudes in low visibility contributed to the hazardous environment.
