Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
The FAA is adopting a new airworthiness directive (AD) for all ATRGIE Avions de Transport R[eacute]gional Model ATR42-500 and ATR72 airplanes. This AD was prompted by a report of damage found on a wire bundle connecting an angle-of-attack (AOA) probe and a multi-function computer (MFC), which can inhibit activation of the stick pusher without any indication to the flight crew by the stall warning system. This AD requires a repetitive operational test for discrepancies of the stall warning system and stick pusher in the flight configuration, an inspection for discrepancies in the wiring bundles between AOA probes and MFCs, and corrective action if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Textron Aviation Inc. (Type Certificate Previously Held by Cessna Aircraft Company) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. (type certificate previously held by Cessna Aircraft Company) Model 560XL airplanes. This AD was prompted by an incident where a Model 560XL airplane experienced an uncommanded engine acceleration with the left engine throttle unresponsive to power commands, including engine shut-off. This AD requires an inspection of the rivet of the left and right throttle quadrant assembly (TQA) sensor link and sensor drive arm pivot for correct installation and corrective actions if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Pipeline Safety: Information Collection Activities
In accordance with the Paperwork Reduction Act of 1995, PHMSA invites comments on proposed revisions to Form PHMSA F 7100.2-1, ``Annual Report for Natural and Other Gas Transmission and Gathering Pipeline Systems,'' and Form PHMSA F 7100.4-1, ``Underground Natural Gas Storage Facility Annual Report,'' both under Office of Management and Budget (OMB) Control No. 2137-0522; and Form PHMSA F 7100.2, ``Incident ReportGas Transmission and Gathering Systems,'' under OMB Control No. 2137-0635.
Airworthiness Directives; Airbus Defense and Space S.A. (Formerly Known as Construcciones Aeronauticas, S.A.) Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2017-19-25, which applies to all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes; and Model C- 295 airplanes. AD 2017-19-25 requires repetitive inspections and operational checks of the affected fuel valves, and corrective actions if necessary. Since the FAA issued AD 2017-19-25, it has been determined that it is necessary to limit the installation of affected parts specified in AD 2017-19-25 to those parts that are maintained in accordance with certain instructions. This proposed AD would continue to require repetitive inspections and operational checks of the affected fuel valves, and corrective actions if necessary. This proposed AD would also limit the installation of affected parts to those that that are maintained in accordance with certain instructions, as specified in a European Union Aviation Safety Agency (EASA), which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A. (type certificate previously held by Embraer S.A.) Model ERJ 190-400 airplanes. This AD was prompted by a report of an in-flight shutdown (IFSD) due in part to failure in the low-pressure compressor (LPC) rotor 1 during operation in high altitude at high thrust settings. This AD requires amending the airplane flight manual (AFM) to incorporate a new limitation and revise certain normal procedures, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Special Conditions: Boeing Commercial Airplanes Model 777-9 Airplane; Overhead Flightcrew Rest Compartment Occupiable During Taxi, Takeoff, and Landing
These special conditions are issued for the Boeing Commercial Airplanes (Boeing) Model 777-9 airplane. This airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport- category airplanes. This design feature is an overhead flightcrew rest (OFCR) compartment occupiable during taxi, takeoff, and landing (TT&L). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
