Federal Aviation Administration August 21, 2017 – Federal Register Recent Federal Regulation Documents

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew a previously approved information collection. National Flight Data Center (NFDC) Web Portal forms are used to collect aeronautical information, detailing the physical description and operational status of all components of the National Airspace System (NAS).

This action modifies VOR Federal airways V-7 and V-67, in the eastern United States due to the planned decommissioning of the Graham, TN, VORTAC navigation aid.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This AD was prompted by reports of cracks initiating at the upper radius of a certain frame and a determination that the current inspection procedure is not reliable in detecting certain cracking of the forward fitting of the frame. This AD requires repetitive inspections to detect cracking of the upper radius of the forward fitting of a certain frame, and related investigative actions and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2014-20-09, which applied to certain Bombardier, Inc., Model DHC-8-400 series airplanes. AD 2014-20-09 required an inspection for missing clamps that are required to provide positive separation between the alternating current (AC) feeder cables and the hydraulic line of the landing gear alternate extension, and related investigative and corrective actions if necessary. This new AD requires removing airplanes from the AD applicability. This AD was prompted by reports of missing clamps that are required to provide positive separation between the AC feeder cables and the hydraulic line of the landing gear alternate extension. We are issuing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2014-16-01 for MD Helicopters, Inc. (MDHI), Model MD900 helicopters. AD 2014-16-01 required an eddy current inspection of the main rotor upper hub assembly (upper hub) for a crack. This AD requires additional inspections and replacing the fillet seal. This AD was prompted by three additional reports of upper hub cracks. The actions of this AD are intended to prevent an unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 777 airplanes. This AD was prompted by reports of cracks on the underwing longerons. This AD requires repetitive inspections of the left and right side underwing longerons for any crack, and related investigative and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.

We are revising an earlier proposal for certain The Boeing Company Model 777 airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding an inspection to determine a part number and to incorporate an airworthiness limitation (AWL) into the maintenance or inspection program. This action also revises the NPRM by specifying a new version of the airline information management system (AIMS) software for airplanes equipped with AIMS-2 software. We are proposing this Airworthiness Directive (AD) to address the unsafe condition on these products. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
