The NTSB's narrative final · quoted from the NTSB record
Prior to takeoff, the helicopter's upper Environmental Control System (ECS) panel was not properly secured. The helicopter departed to an off-station platform and returned back to the home base. At an unknown time during the flight the ECS panel departed the helicopter, resulting in damage to one main rotor blade and one tail rotor blade. The helicopter's ECS and auxiliary power unit panels were both painted the same color, impeding visual inspection of the panels for proper closure.
