Federal Aviation Administration December 7, 2005 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all EMBRAER Model EMB-145, -145ER, - 145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The existing AD currently requires repetitive inspections to detect cracking or failure of the rod ends of the aileron power control actuator (PCA), and corrective actions if necessary. This proposed AD would require the same repetitive inspections of additional parts at new inspection intervals for certain airplanes; provide new corrective actions; and provide an optional terminating action for the proposed requirements. This proposed AD results from the issuance of mandatory continuing airworthiness information by the Brazilian airworthiness authority. We are proposing this AD to detect and correct cracking or breaking of the rod ends and connecting fittings of the aileron PCA, which could result in reduced controllability of the airplane.

This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and/or Weather Takeoff Minimums for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
