Safety record

Accident & incident history

2015-07-12 Accident · Escalante, UT Damage: Substantial Serious injury NTSB · GAA15LA131
Reported aircraft: Robinson R22 Beta — a different aircraft that carried the N441MM registration before this airframe.
Probable cause: The pilot s inadequate preflight planning and his subsequent decision to attempt to climb over rising terrain with the helicopter over maximum gross weight while operating in high-density altitude conditions with a tailwind, which resulted in its inability to maintain a positive climb rate and a subsequent impact with terrain.
