AD: Bell Helicopter Textron, Inc. (Bell) Helicopters

AD NUMBER: 2012-17-08

PRODUCT: Bell Model 204B, 205A, 205A-1, 205B, and 212 helicopters.
SUBJECT: Airworthiness Directive 2012-17-08
ACTION: Final Rule

SUMMARY: The FAA is superseding four airworthiness directives related to the main rotor yoke (yoke) on the products listed above to retain certain inspections and certain life limits, to require an increased inspection frequency for certain yokes, and to expand these inspections and retirement lives to other yokes.

This airworthiness directive is prompted by past reports of cracks in the yoke, another recent report of a cracked yoke, and the decision that other yokes, approved based on identicality, need to be subject to the same inspection requirements and retirement lives. The actions are intended to detect a crack in a yoke to prevent failure of the yoke, and subsequent loss of control of the helicopter.

DATES: This AD is effective February 27, 2013.
