Department of Transportation August 9, 2021 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-8, 737-9, and 737-8200 (737 MAX) airplanes; and certain Model 737-800 and 737-900ER series airplanes. This AD was prompted by the determination that the aft cargo compartment fire suppression capability is reduced if the airplane is dispatched or released with failed electronic flow control of air conditioning packs, as is currently allowed by these airplane models' master minimum equipment lists (MMELs). This AD prohibits the carriage of cargo in the aft cargo compartment when the airplane is dispatched or released with failed electronic flow control of air conditioning packs. The FAA is issuing this AD to address the unsafe condition on these products.

In compliance with the Paperwork Reduction Act of 1995, this notice announces that the Information Collection Request (ICR) abstracted below is being forwarded to the Office of Management and Budget (OMB) for review and comments. Comments are invited on whether the proposed collection of information is necessary for the proper performance of the functions of the Department, including whether the information will have practical utility; the accuracy of the Department's estimate of the burden of the proposed information collection; ways to enhance the quality, utility and clarity of the information to be collected; and ways to minimize the burden of the collection of information on respondents, including the use of automated collection techniques or other forms of information technology. A Federal Register Notice with a 60-day comment period soliciting comments on the following information collection was published on April 7, 2021.

This notice sets forth the reasons for the denial of a petition, DP21-001, submitted by Mr. Derek Colvin to NHTSA (the ``agency'') by a letter dated November 20, 2020. The petition requests that the agency initiate a safety defect investigation into an alleged defect in the reversing light system experienced in certain Model Year (MY) 2013 Porsche 911 Carrera manual transmission vehicles (the ``subject vehicles''). As the driver shifts the gear into reverse, the reversing light fails to illuminate. After conducting a technical review of: (1) The consumer complaint submitted by the petitioner; (2) consumer complaint information in NHTSA's database; and (3) information provided by Porsche in response to our Information Request letter regarding reversing light failure to illuminate and complaints received by Porsche, NHTSA's Office of Defect Investigations (ODI) has concluded that no further investigation of the issue raised by the petition is warranted and the agency, accordingly, has denied the petition.

This action amends Class E airspace extending upward from 700 feet above the surface at County Memorial Airport, New Madrid, MO. The FAA is taking this action as a result of an airspace review caused by the decommissioning of the Malden Very High Frequency Omnidirectional Range (VOR) collocated with Tactical Air Navigation (VORTAC) navigational aid as part of the VOR Minimum Operational Network (MON) Program. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) in the area.

The FAA proposes to supersede Airworthiness Directive (AD) 2018-25-16, which applies to certain Airbus Defense and Space S.A. Model CN-235, CN-235-200, and CN-235-300 airplanes. AD 2018-25-16 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2018-25-16, the FAA has determined that additional new or more restrictive airworthiness limitations, including inspections for discrepancies (cracking) of certain structural elements, are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, and repetitive inspections for discrepancies (cracking) of certain structural elements and corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports of damage to the thrust reverser (TR) translating sleeve secondary sliders due to contact between the slider and the slider track liner. This damage was only found on TR sleeves installed on certain engines. This proposed AD would require determining the serial number of the TR and performing applicable on-condition actions; or replacing the TR with a serviceable TR. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as insufficient separation of ground terminations for individual power sources and static grounds. This proposed AD would require inspecting and separating, if applicable, the battery and generator common ground connections on the airframe. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Saab AB, Support and Services Model SAAB 340B airplanes. This proposed AD was prompted by a report that the circuit breaker for the emergency cabin lighting tripped without fault in the system. This proposed AD would require replacing a certain circuit breaker with a part having a higher rating, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
