Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA-360C helicopters. This action requires replacement of the main gear box (MGB) input bevel pinion (bevel pinion). This amendment is prompted by service reports of bevel pinion fatigue cracking. This condition, if not corrected, could result in failure of the MGB and a subsequent forced landing.
