Federal Aviation Administration December 31, 2018 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A320-214, A320-232, A320-233, A321-211 and A321-231 airplanes. This AD was prompted by an investigation that revealed that the outer cylinder of a certain ram air turbine (RAT) actuator was not properly deburred in accordance with manufacturing specifications. This AD requires a replacement of affected RAT actuators. We are issuing this AD to address the unsafe condition on these products.

This action modifies Class E airspace extending upward from 1,200 feet above the surface in Alaska at Wiley Post/Will Rogers Memorial Airport, Barrow; Chevak Airport; Clarks Point Airport; Elim Airport; and Golovin Airport. This action adds exclusionary language to the legal descriptions of these airports to exclude Class E airspace extending beyond 12 miles from the shoreline, and ensures the safety and management of aircraft within the National Airspace System. Also, an editorial change is made in the associated airspace designation for Chevak Airport.
