FAA Proposes Robinson R22 Rotor Blade Airworthiness Directive

The FAA proposes to supersede an existing airworthiness directive for the Robinson R22, R22 Alpha, R22 Beta, R22 Mariner, R44 and R44 II with certain main rotor blades. The existing AD currently requires inspecting each blade at the skin-to-spar line for debonding, corrosion, a separation, a gap or a dent and replacing any damaged blade with an airworthy blade. The proposed actions are intended to detect debonding of the blade skin, which could result in blade failure and subsequent loss of control of the helicopter, and to correct the unsafe condition by replacing the main rotor blades with new blades that do not require the AD inspection.
