Federal Aviation Administration March 8, 2018 – Federal Register Recent Federal Regulation Documents

The FAA proposes to rule and invite public comment on the release of land at the Arapahoe County Public Airport, Englewood, CO.

We propose to adopt a new airworthiness directive (AD) for all Quest Aircraft Design, LLC Model KODIAK 100 airplanes. This proposed AD was prompted by reports of cracks found in certain nose landing gear forks. This proposed AD would require a one-time inspection to determine if the affected nose landing gear fork is installed, repetitive inspections of the affected nose landing gear fork for cracks, repetitive inspections of the shimmy damper bracket for looseness if the affected nose landing gear fork is installed, and rework/replacement of parts as necessary. We are proposing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Honeywell International Inc. AS907 series turbofan engines. This AD was prompted by seven loss-of-thrust-control events attributed to water intrusion of the engine electronic control unit (ECU). This AD requires applying sealant to identified areas of the ECU and requires inserting a copy of certain airplane operating procedures into the applicable flight manuals. We are issuing this AD to address the unsafe condition on these products.

This action amends Class E airspace extending upward from 700 feet or more above the surface at Marshall County Airport, Moundsville, WV, due to the FAA's reevaluation of the airspace. This amendment results in an increase from a 6.2-mile radius to a 7.3-mile radius of the airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport. This action also updates the geographic coordinates of this airport.

This action amends Class E airspace at Berlin, NH, due to the addition of a localizer performance with vertical guidance function (LPV) to runway 18 being created for Berlin Regional Airport (formerly Berlin Municipal Airport). This action also updates the geographic coordinates of the airport to coincide with the FAA's aeronautical database.

We are adopting a new airworthiness directive (AD) for Pilatus Aircraft Limited Model PC-7 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 the brakes remaining activated after release of the brake pedal. We are issuing this AD to require actions to address the unsafe condition on these products.
