FINAL REPORT: [official English translation]

4.1 Findings
 The Romanian Airclub had no information regarding the flying activity with aircraft certified by ASC, on this flight field;
 The pilot did not hold a license issued/recognized by the Romanian Airclub;
 Pilot was not authorized to perform adjustments on the controls chain;
 The technical expertise of the broken rods in the chain of the rotor head controls, confirmed that they failed before impact and fire.

4.2 Cause of accident
The cause of the accident was the loss of control of the rotor head as a result of the breakage of a threaded rod (Rod 1) from the roll control mechanism/system.
Favoring cause: several non-compliant adjustments made by the pilot, which have induced successive and repeated physical stresses within Rod 1.


Condolences, etc.
