Federal Aviation Administration January 11, 2012 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for all Agusta S.p.A. (Agusta) Model A109, A109A, A109A II, A109C, A109K2, A109E, A109S, and A119 helicopters. This proposed AD is prompted by a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI AD states that a Model A109E helicopter has experienced a failure of the tail rotor pitch control link assembly caused by a production defect. The proposed actions are intended to prevent failure of a tail rotor pitch control link and subsequent loss of control of the helicopter.

This rulemaking would allow qualified operators to conduct lower than standard instrument flight rules (IFR) airport operations at military airports or outside the United States when authorized to do so by their operations specifications. This action is necessary because the current regulatory section limits certain operators to a takeoff minimum visibility of 1 mile, and a landing minimum visibility of \1/2\ mile when conducting IFR operations at those airports, even when the operator has demonstrated the ability to safely conduct operations in lower visibility. The intended effect of this final rule is to bring the identified regulatory section into alignment with other sections of the regulations that currently permit lower than standard IFR operations at domestic civilian, foreign, and military airports when authorized to do so.

These special conditions are issued for the Boeing Model 767- 300 series airplanes. These airplanes will have a novel or unusual design feature associated with seats with inflatable lapbelts. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This action extends the comment period for an NPRM that was published on November 28, 2011. In that document, the FAA proposed to establish restricted area airspace within the Devils Lake East Military Operations Area (MOA), overlying Camp Grafton Range, in the vicinity of Devils Lake, ND. This extension is a result of a request from the North Dakota Aviation Council (NDAC), representing eight member groups including the Airport Association of North Dakota, North Dakota Business Aviation Association, North Dakota Pilots Association, North Dakota Professional Aviation Mechanics Association, and North Dakota Flying Farmers, to extend the comment period to the proposal.

We are adopting a new airworthiness directive (AD) for Schempp-Hirth Flugzeugbau GmbH Model Discus 2cT gliders. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as small cracks which have been found on engine pylons in the area of the lower engine support that have not been detected during the standard daily inspection. This condition, if not detected and corrected, could lead to an engine pylon failure resulting in loss of control of the glider. We are issuing this AD to require actions to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for Socata Model TBM 700 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as installation of the wrong (switched) aileron control cables in the wing. This unsafe condition could lead to restricted movement of the aileron, resulting in reduced control of the airplane. We are issuing this AD to require actions to address the unsafe condition on these products.
