What happened
On February 11, 2018, at approximately 13:3/UTC, an Ícaros Adventure trike, registration PU-ADD, took off from an open field in Rio Branco, Acre, Brazil. The aircraft was performing a local flight with a pilot and one passenger on board. Shortly after takeoff, while initiating a left-hand turn, the aircraft entered a steep descent. According to an eyewitness, the aircraft maintained a descent angle of approximately 45 degrees relative to the ground until it impacted the terrain. The impact caused substantial damage to the aircraft. The pilot died at the scene, and the passenger, who sustained serious injuries, passed away two days later.
The investigation
CENIPA investigators established that the aircraft held a valid Experimental Brand Certificate (CME) and a Flight Authorization Certificate (CAV). However, essential documentation, including the Annual Maintenance Inspection Report (RIAM) and the Aeronautical Insurance Certificate (RETA), was not on board the aircraft at the time of the accident.
Furthermore, the investigation revealed that the individual operating the aircraft was not legally qualified to fly. While the individual had initiated the process for an ANAC identification code, they had not completed the necessary training or certification. The investigation was ultimately interrupted because the operation was conducted in direct violation of established aeronautical regulations, meaning the occurrence was a result of non-compliance rather than a technical failure that could be addressed through safety recommendations.
Findings
- The pilot lacked a valid Recreational Pilot Certificate (CPR) or Sport Pilot Certificate (CPD).
- The pilot did not possess a valid Ultralight Pilot Medical Certificate (CMPU).
- The pilot was operating the aircraft without the required legal qualifications.
- Required maintenance and insurance documentation (RIAM and RETA) were not present on board.
