Airworthiness Directives; MD Helicopters, Inc. Model MD900 Helicopters

This amendment adopts a new airworthiness directive (AD) for MD Helicopters, Inc. (MDHI) Model MD900 helicopters that requires inspecting and, if necessary, repairing the longitudinal drive link (drive link) and modifying certain nonrotating swashplate (swashplate) assemblies. This AD also requires recording compliance with the AD on a component history card or equivalent record. This amendment is prompted by reports of damage to the drive link assembly caused by the sharp inner edge of the bushing in the swashplate assembly. The actions specified by this AD are intended to prevent damage to the drive link, loss of control of the main rotor system, and subsequent loss of control of the helicopter.
