AD NUMBER: 2008-19-02
MANUFACTURER: Bell
SUBJECT: Airworthiness Directive 2008-19-02
SUMMARY: We are superseding an existing airworthiness directive (AD) for Bell Helicopter Textron Canada (Bell) Model 222, 222B, 222U, 230, and 430 helicopters. That AD currently requires visually inspecting the main rotor hydraulic actuator support (support) to verify the presence of all dowel pins and sealant between the support and transmission and verifying the proper torque of each attaching nut (nut).

This AD requires the same actions as the existing AD and also requires repetitive actions at intervals not to exceed 600 hours time-in-service (TIS) or 12 months, whichever occurs first.

This AD is prompted by the discovery that a 12-month compliance requirement was correctly included in an Emergency AD (EAD) that we issued but was inadvertently omitted when we published the Final rule; request for comments following the issuance of the EAD.

The actions specified by this AD are intended to prevent failure of the support and subsequent loss of control of the helicopter.
