Federal Aviation Administration April 16, 2018 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318 and A319 series airplanes; Model A320-211, A320-212, A320-214, A320-216, A320-231, A320-232, and A320-233 airplanes; and Model A321-111, A321-112, A321-131, A321-211, A321-212, A321-213, A321- 231, and A321-232 airplanes. This proposed AD was prompted by reports of missing assembly hardware on the trimmable horizontal stabilizer actuator (THSA). This proposed AD would require repetitive inspections and checks of the lower and upper THSA attachments and applicable related investigative and corrective actions; a one-time inspection of the THSA lower attachment and replacement as applicable; and, for certain airplanes, activation of the electrical load sensing device (ELSD) and concurrent modifications. We are proposing this AD to address the unsafe condition on these products.

This action proposes to establish Class E airspace extending upward from 700 feet above the surface, at Hobby Field, Creswell, OR, to accommodate new area navigation (RNAV) procedures at the airport. This action would ensure the safety and management of instrument flight rules (IFR) operations within the National Airspace System.

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by a report indicating that during a fleet survey on a retired Model 737 airplane, cracking was found common to the windshield and aft sill web. This proposed AD would require, at certain locations, repetitive high frequency eddy current (HFEC) inspections of the windshield and aft sill web, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2005-12-16, which applied to all Fokker Services B.V. Model F28 Mark 0100 airplanes. AD 2005-12-16 required an inspection to determine the part number of the passenger service unit (PSU) panels for the PSU modification status, and corrective actions if applicable. This new AD requires an inspection of the PSU panels and the PSU panel/airplane interface connectors for discrepancies, and corrective actions if necessary. This AD also removes airplanes from the applicability. This AD was prompted by reports of smoke in the passenger compartment during ground operations and in-flight, and a determination that the modification actions required by AD 2005-12-16 might not have been implemented correctly. We are issuing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2015-19-12, which applied to certain The Boeing Company Model 767 airplanes. AD 2015-19-12 required a general visual inspection of certain lap splices for missing fasteners, and all applicable related investigative and corrective actions. This AD retains the actions required by AD 2015-19- 12 and revises the applicability by adding airplanes. This AD was prompted by reports indicating that certain fasteners were not installed in a certain stringer lap splice on certain airplanes. We are issuing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2015-02- 17, which applies to all Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes. AD 2015-02-17 requires revising the electrical emergency configuration procedure in the Emergency Procedures section of the airplane flight manual (AFM) to include procedures for deploying the ram air turbine manually to provide sufficient hydraulic power and avoid constant speed motor/generator (CSM/G) shedding. Since we issued AD 2015-02-17, we have determined that replacement or modification of the two flight warning computers (FWCs) is necessary to address the identified unsafe condition. This proposed AD would add a requirement to replace or modify the two FWCs. This proposed AD would also remove airplanes from the applicability. We are proposing this AD to address the unsafe condition on these products.
