Federal Aviation Administration August 2023 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2019-25-17, which applies to all The Boeing Company Model 737-600, - 700, -700C, -800, -900, and -900ER series airplanes. AD 2019-25-17 requires revising the existing airplane flight manual (AFM) to prohibit selection of certain runways for airplanes equipped with certain software. Since the FAA issued AD 2019-25-17, Boeing has developed new software to address the unsafe condition. This proposed AD would retain the requirements of AD 2019-25-17. This proposed AD would also require installing the new software and performing a software configuration check, which would terminate the AFM revision. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 190-300 and -400 airplanes. This AD was prompted by identification that, during simulations, analysis, and an in-service event of the airplane, a stall warning system activation (i.e., stick shaker) and angle of attack (AOA) limiter engagement may occur in certain vertical gust conditions with specific intensity and frequency. This AD requires revising the Limitations section of the existing airplane flight manual (AFM) to incorporate minimum operating speeds during flight at moderate or severe turbulence conditions, 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.

The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-300 and -400 airplanes. This AD was prompted by reports of missing parts on the main landing gear (MLG) side stay upper spindle assembly. This AD requires inspection of the left-hand (LH) and right-hand (RH) MLG side stay upper spindle assembly attachments, and corrective actions if necessary, 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.

The FAA is superseding Airworthiness Directive (AD) 2019-21- 06, which applied to certain Ipeco Holdings Limited (Ipeco) pilot and co-pilot seats. AD 2019-21-06 required modification and re- identification of the affected seats, initial and repetitive inspections of the affected track lock springs and, depending on the findings, replacement of the track lock springs with a part eligible for installation. Since the FAA issued AD 2019-21-06, the FAA determined the need for a mandatory terminating action to the track lock spring inspections. This AD is prompted by reports of track lock spring failures occurring on affected seats. This AD retains the requirements of AD 2019-21-06. This AD also adds a mandatory terminating action for the initial and repetitive inspections of the affected track lock springs. The FAA is issuing this AD to address the unsafe condition on these products.

This action changes the effective date of a final rule published in the Federal Register on July 17, 2023, that amends the United States Area Navigation (RNAV) route T-230 in the vicinity of St. Paul Island, AK, in support of a large and comprehensive T-route modernization project for the state of Alaska. The effective date in the final rule was incorrectly stated as August 10, 2023. The correct effective date for Airspace Docket No. 19-AAL-63 is October 5, 2023.

This notice contains a summary of a petition seeking relief from specified requirements of Federal Aviation Regulations. The purpose of this notice is to improve the public's awareness of, and participation in, the FAA's exemption process. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

This action establishes United States Area Navigation (RNAV) T-route, T-380, in the vicinity of Emmonak, AK in support of a large and comprehensive T-route modernization project for the state of Alaska.

The FAA proposes to supersede Airworthiness Directive (AD) 2019-12-07, which applies to all Airbus SAS Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and - 233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2019-12-07 requires replacement of both main landing gear (MLG) shock absorbers, an identification of affected MLG sliding tubes; inspection of affected chromium plates and sliding tube axles for damage; and replacement of the sliding tube if necessary. AD 2019-12-07 also requires repetitive inspections of affected MLG sliding tubes for cracking, replacement of cracked MLG sliding tubes, and eventual replacement of each affected MLG sliding tube. Since the FAA issued AD 2019-12-07, the FAA has determined that additional MLG sliding tubes are affected by the unsafe condition and that the repetitive inspection interval may be extended. This proposed AD would continue to require the actions specified in AD 2019-12-07 and would require repetitive inspections of additional MLG sliding tubes, replacement if necessary, and eventual replacement of the additional MLG sliding tubes. This proposed AD would also extend the repetitive inspection interval. This proposed AD would also prohibit the installation of affected parts under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to rule and invites public comment on the release of land at the Brunswick Golden Isles Airport(BQK), Brunswick, Georgia.

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 767 airplanes. This AD was prompted by reports of inoperative manual and alternate horizontal stabilizer trim switches. This AD requires repetitive inspections for immersion of each limit switch and position transmitter module (LSPTM) and of the LSPTM electrical wiring, repetitive inspections for blockage of the drain holes and cleaning of each drain hole, repetitive inspections for loose or cracked leveling compound, and applicable on-condition actions. For certain airplanes, this AD also requires installing two new drain holes, performing repetitive inspections for blockage of the drain holes and cleaning each drain hole, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
