Requires an initial dye penetrant inspection of the main rotor drive forward flexplate (flexplate), and repetitive visual inspections of certain installed flexplates.
Full official abstract
This amendment supersedes an existing airworthiness directive (AD), applicable to Robinson Helicopter Company (RHC) Model R22 helicopters, that currently requires an initial dye penetrant inspection of the main rotor drive forward flexplate (flexplate), and repetitive visual inspections of certain installed flexplates. This amendment is prompted by three accidents reported by the airworthiness authority of Australia involving failure of the flexplate, located between the main rotor gearbox and clutch assembly. The actions specified by this AD are intended to prevent failure of the flexplate, failure of the main rotor drive system, and subsequent loss of control of the helicopter.
