AD: MD Helicopters, Inc.

AD NUMBER: 2012-21-01

PRODUCT: MD Helicopters, Inc. (MDHI), Model MD900 helicopters.
SUBJECT: Airworthiness Directive 2012-21-01
ACTION: Final Rule

SUMMARY: The FAA is adopting a new airworthiness directive (AD) to supersede an existing airworthiness directive for the product listed above.

The existing AD requires a visual inspection, and if necessary, an eddy current inspection of the main rotor lower hub assembly (lower hub) for a crack. If a crack exists, the AD requires replacing the lower hub with an airworthy lower hub before further flight. Because that AD was immediately effective, we declined to require certain long-term actions prior to public comment.

This superseding AD will require the same inspections as the existing AD but will also require long-term recurring inspections and replacing the lower hub with an airworthy lower hub. The FAA is issuing this AD to detect a crack in the lower hub and prevent failure of the lower hub and subsequent loss of control of the helicopter.

DATES: This AD is effective November 27, 2012.

FMI: AD
