What happened
On 19 October 2013, at approximately 13:25 UTC, a Pilatus PC-6 engaged in aerial work for parachute drops crashed near the village of Gelbressée, located about 12.5 km east-northeast of EBNM airfield. The aircraft, which was performing a climb at the time of the accident, was carrying 10 parachutists and one pilot. The impact resulted in 11 fatal injuries.
The investigation
The AAIU(Be) conducted a full safety investigation, supported by international authorities including the Swiss SUST, Canadian TSB, US NTSB, and French BEA. The technical examination involved a detailed reconstruction of the wreckage and a visual inspection of the accident site to locate all debris. Investigators focused on several critical components, including the flight controls, the engine, the propeller, and the trim actuator and its electrical circuits. Furthermore, laboratory analysis was performed on fractures found in the left wing and strut to determine the sequence of structural failure. The team also analyzed radar data, air traffic control communications, meteorological conditions, and bird activity reports, while interviewing witnesses and members of the parachute club.
Safety action
Following an initial review of the legal framework governing parachute operations, the AAIU(Be) identified a need for improved organizational structures and enhanced surveillance of such activities by the competent authority. On 2 January 2014, the AAIU(Be) issued a safety recommendation to the Belgian Civil Aviation Authority (BCAA) to review regulatory requirements for parachute drops to ensure safety levels are acceptable and oversight is appropriately adapted. In response, the BCAA began developing new operating procedures and implemented the EASA Part-SPO regulation in April 2015 to provide a more robust framework for parachute clubs.
