Federal Aviation Administration June 3, 2020 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD requires a repetitive check of the fuel quantity indicating system (FQIS) fuel quantity calculation for the center wing tank (CWT) fuel quantity, developing a process to provide documentation to the flight crew that this check was done, and revising the existing airplane flight manual (AFM) to incorporate verification procedures and flight crew awareness. This AD was prompted by reports of discrepancies between the FQIS fuel quantity and the refueling truck uploaded fuel amount, followed by certain engine-indicating and crew-alerting system (EICAS) messages. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to amend VHF Omnidirectional Range (VOR) Federal airways V-2, V-14, V-31, V-33, V-36, V-84, V-164, V-252, and V- 510 due to the planned decommissioning of the VOR portion of the Buffalo, NY (BUF), VOR/Distance Measuring Equipment (VOR/DME) navigation aid (NAVAID). The Buffalo VOR provides navigation guidance for portions of the affected VOR Federal airways and is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.

The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to various normal and transport category rotorcraft with certain Honeywell enhanced ground proximity warning systems (EGPWS) installed. The NPRM was prompted by a software defect that prevents the EGPWS from providing terrain warnings. The NPRM would have required updating the software version of the EGPWS. Since issuance of the NPRM, the FAA has determined that the unsafe condition no longer exists and has confirmed that the majority of operators have updated their software as specified in the NPRM. Accordingly, the NPRM is withdrawn.

The FAA proposes to adopt a new airworthiness directive (AD) for Leonardo S.p.A. Model AW169 and AW189 helicopters. This proposed AD was prompted by a report of a broken extrusion rubber window seal. This proposed AD would require installation of a reinforcement around the rubber filler wedge where the extrusion rubber window seal meets the door's emergency exit handle. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Guntersville Municipal Airport-Joe Starnes Field (formerly Guntersville Municipal Airport), Guntersville, AL, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures serving this airport. This action would also update the geographic coordinates of the airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

The FAA is revising an earlier proposal for certain Piper Aircraft, Inc. (Piper) Models PA-28-140, PA-28-150, PA-28-151, PA-28- 160, PA-28-161, PA-28-180, PA-28-181, PA-28-235, PA-28R-180, PA-28R- 200, PA-28R-201, PA-28R-201T, PA-28RT-201, PA-28RT-201T, PA-32-260, and PA-32-300 airplanes. The notice of proposed rulemaking (NPRM) was prompted by a report of a wing separation caused by fatigue cracking in a visually inaccessible area of the lower main wing spar cap. This action revises the NPRM by adding and removing certain models of airplanes in the Applicability, proposing to require the use of service information that was issued since the NPRM, and clarifying some of the proposed actions. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those proposed in the NPRM, the FAA is reopening the comment period to allow the public the chance to comment on these changes.
