Federal Aviation Administration June 28, 2016 – Federal Register Recent Federal Regulation Documents

This action proposes to remove Class E surface area airspace at Farmington Regional Airport, Farmington, MO; and modify Class E airspace extending upward from 700 feet above the surface at Bill Martin Memorial Airport, Ava, MO; Cameron Memorial Airport, Cameron, MO; Chillicothe Municipal Airport, Chillicothe, MO; Farmington Regional Airport, Farmington, MO; and Festus Memorial Airport, Festus, MO. Decommissioning of non-directional radio beacons (NDBs), cancellation of NDB approaches, and implementation of area navigation (RNAV) procedures have made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the above airports.

The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by San Antonio International Airport under the provisions of 49 U.S.C. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR part 150. These findings are made in recognition of the description of Federal and nonfederal responsibilities in Senate Report No. 96-52 (1980). On December 29, 2014, the FAA determined that the noise exposure maps submitted by San Antonio International Airport under part 150 were in compliance with applicable requirements. On June 2, 2015, the FAA approved the San Antonio International Airport noise compatibility program. Both of the recommendations of the program were approved.

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS 365 N3 helicopters. This AD requires inspecting the cabin and cockpit for labels, placards, or markings that provide jettison procedure instructions for cabin doors, removing any labels, placards, or markings that are in an incorrect location, and installing placards where they are missing. This AD is prompted by the determination that placards had not been installed according to specifications on newly manufactured helicopters. The actions are intended to provide exit procedures during an emergency.

We are revising an earlier proposed airworthiness directive (AD) for all Airbus Model A318 and A319 series airplanes, A320-211, - 212, -214, -231, -232, and -233 airplanes, and A321 series airplanes. The NPRM proposed to require an inspection to identify the part number and serial number of the main landing gear (MLG) sliding tubes installed on the airplane; and inspection of affected chromium plates for damage; an inspection of affected sliding tube axles for damage; and replacement of the sliding tube if necessary. The NPRM was prompted by a report of a rupture of a MLG sliding tube axle. This action revises the NPRM by removing certain service information that does not adequately address the identified unsafe condition and revising the compliance method. We are proposing this supplemental NPRM (SNPRM) to detect and correct cracks in the axle and (partial) detachment of the axle and wheel from the sliding tube, which could result in failure of an MLG. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-700 and -700C series airplanes. This proposed AD was prompted by a report that for airplanes with blended winglets, the nose-up pitch trim limit and associated warning for the horizontal stabilizer control system will allow take-off with incorrect trim settings. This proposed AD would require, depending on airplane configuration, replacing the pitch trim light plates on the flight deck control stand, relocating the position warning horn switches of the horizontal stabilizer, revising the software, removing the placard, and doing related investigative and corrective actions if necessary. We are proposing this AD to prevent take-off with incorrect settings of the horizontal stabilizer pitch trim system. Settings outside of the appropriate pitch trim limits could result in loss of controllability of the airplane during take-off.
