What happened
On May 7, 2013, a Cessna TU206G, registration PP-PMC, departed from Rondonópolis, Mato Grosso, for a verification flight following an initial technical inspection. The aircraft, carrying a pilot and three passengers, proceeded to the São Lourenço River dam to perform a water landing.
While the initial landing was completed without issue, the accident occurred during a subsequent 180-degree turn. According to the pilot, a wave struck the right float, causing the aircraft to capsize and settle in an inverted position. The four occupants successfully evacuated the cabin and climbed onto the floats to await rescue. However, while waiting for assistance, one passenger attempted to swim to the shore and subsequently drowned. The aircraft remained submerged for ten days, resulting in substantial damage.
The investigation
CENIPA's investigation focused on the sequence of events leading to the capsizing and the regulatory compliance of the crew. Investigators examined the aircraft's weight and balance, the pilot's qualifications, and the environmental conditions at the time of the occurrence. The investigation also noted that the aircraft was operating within its weight and balance limits, though a lateral imbalance of 43kg to the right and 47kg forward was identified.
Findings
- The pilot did not possess the required technical certificate (CHT) to operate a single-engine amphibious aircraft.
- None of the occupants were wearing life jackets at the time of the accident.
- The aircraft experienced a lateral weight imbalance during the maneuver.
- The pilot was not qualified to conduct the flight under the existing regulations.
