Federal Aviation Administration August 28, 2019 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2019-18518
Type: Rule
Date: 2019-08-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding Airworthiness Directive (AD) 2016-07- 22, which applied to all Airbus SAS 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); and Model A310 series airplanes. AD 2016-07-22 required modifying the electrical routing installation at the right-hand (RH) and left-hand (LH) wings to achieve a minimum distance between wiring bundles and surrounding structures. This new AD retains the requirements of AD 2016-07-22 and, for certain airplanes, adds a requirement to further modify the electrical installations in both wings, as specified in a European Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by reports of missing installation information for certain airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2019-18517
Type: Proposed Rule
Date: 2019-08-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to certain Bombardier, Inc., Model DHC-8-400 series airplanes. The NPRM was prompted by reports of wear on fuel couplings, bonding springs, and sleeves as well as fuel tube end ferrules and fuel component end ferrules. The NPRM would have required repetitive inspections of the existing clamshell coupling bonding wires, fuel couplings, and associated sleeves for certain criteria, and replacement as necessary. The NPRM would also have required repetitive inspections of the fuel tube end ferrules, fuel component end ferrules, and ferrule o-ring flanges for damage and wear, and rework as necessary. Since issuance of the NPRM, the FAA determined that more restrictive airworthiness limitations are also necessary, that an optional terminating modification is appropriate for certain airplanes, and that the NPRM does not adequately address the identified unsafe condition. Accordingly, the NPRM is withdrawn.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2019-18516
Type: Rule
Date: 2019-08-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding Airworthiness Directive (AD) 2018-20- 06, which applied to certain Airbus SAS Model A300 F4-600R series airplanes. AD 2018-20-06 required repetitive high frequency eddy current (HFEC) inspections of the aft lower deck cargo door (LDCD) frame forks; a one-time check of the LDCD clearances; a one-time detailed visual inspection of hooks, eccentric bushes, and x-stops; and corrective actions if necessary. This AD retains the actions of AD 2018-20-06 and requires new compliance times, depending on frame fork configuration. This AD was prompted by a report of two adjacent frame forks that were found cracked on the aft LDCD of two airplanes during scheduled maintenance, and a determination that certain compliance times need to be revised. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Learjet, Inc. Airplanes
Document Number: 2019-18427
Type: Rule
Date: 2019-08-28
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding Airworthiness Directive (AD) 2017-11-09 for certain Learjet, Inc. (Learjet), Model 60 airplanes. AD 2017-11-09 required a one-time fluorescent dye penetrant inspection of the fuselage skin for corrosion, additional related inspections and corrective actions as necessary, and reporting the inspection results to the FAA. This AD clarifies the compliance time for the inspection and corrects an error in the inspection area of the fuselage skin. This AD was prompted by the identification of an error in the fluorescent dye penetrant inspection of the fuselage skin and an ambiguity in the compliance time for the fluorescent dye penetrant inspection. The FAA is issuing this AD to address the unsafe condition on these products.
