What happened
On March 31, 2006, a Robinson R22 helicopter, registration PP-MAK, crashed into a mountainside in the municipality of Taió, Santa Catarina. The flight originated from Lages (SBLJ) with the destination of Ponta Grossa (SSZW), as part of a larger relocation mission to move the aircraft to Ribeirão Preto for scheduled maintenance.
The pilot made his last radio contact with the Curitiba Area Control Center at 11:4 . After the aircraft failed to arrive at its destination, a search was initiated following a report from the pilot's family. The wreckage was eventually located on April 13, 2006, in a densely forested and difficult-to-access area. The pilot sustained fatal injuries at the scene, and the aircraft was destroyed.
The investigation
CENIPA's investigation established that the pilot was flying under Visual Flight Rules (VFR) but encountered low clouds and light rain. To maintain visual contact with the ground, the pilot began flying at increasingly lower altitudes. The investigation found that the pilot was navigating primarily via GPS without the use of aeronautical charts, which meant he was unaware of the high terrain located to the left of his intended track.
Investigators also noted that the pilot was performing his first long-distance cross-country flight alone and lacked sufficient experience in route navigation. Furthermore, evidence indicated the pilot had answered a cellular phone call during the flight prior to the Lages departure. The investigation concluded that the pilot's reliance on GPS provided a false sense of security, leading him to fly into terrain under conditions that effectively required IFR capabilities for which he was not rated.
Findings
- Inadequate flight planning: The pilot did not use aeronautical charts for route planning or execution, leaving him unaware of terrain elevations.
- Improper navigation: Over-reliance on GPS as a primary navigation tool rather than an auxiliary aid.
- Violation of safety minimums: The pilot failed to maintain the required altitude of 200 feet above the highest obstacle in the vicinity.
- Adverse weather: The presence of low ceilings and light rain prompted the pilot to descend into dangerous terrain.
- Lack of experience: The pilot was performing his first solo long-range navigation and lacked sufficient theoretical knowledge for such operations.
- Decision making: The pilot chose to continue the flight despite deteriorating meteorological conditions.
