Department of Transportation December 13, 2022 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports of a loss of water pressure during flight and water leaks that affected multiple pieces of electronic equipment. This proposed AD would require a detailed visual inspection of all door 1 and door 3 lavatory and galley potable water systems for any missing or incorrectly installed clamshell couplings and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2019-18-07, which applies to certain Airbus SAS 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 2019-18-07 requires repetitive rototest inspections of the open tack holes and rivet holes at the cargo floor support fittings of the fuselage, including doing all applicable related investigative actions and repair if necessary. AD 2019-18-07 also adds actions (modification) for certain airplanes. Since the FAA issued AD 2019-18-07, it was determined that certain airplanes need to do additional work. This proposed AD would continue to require the actions in AD 2019-18-07 and would require additional work for certain airplanes, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is revising a notice of proposed rulemaking (NPRM) that would have applied to certain Gulfstream Aerospace LP Model Gulfstream 200 airplanes. This action revises the NPRM by adding Model Galaxy airplanes to the applicability. 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 in the NPRM, the FAA is requesting comments on this SNPRM.

The FAA is correcting a final rule that appeared in the Federal Register on November 16, 2022. The Final Rule incorrectly listed the effective date as 0901 UTC, December 29, 2022. This action corrects the effective date to 0901 UTC, February 23, 2023.

The FAA proposes to supersede Airworthiness Directive (AD) 2015-09-04 R1, which applies to DG Flugzeugbau GmbH Model DG-1000T gliders equipped with a Solo Kleinmotoren GmbH (currently Solo Vertriebs-und Entwicklungs-GmbH) (Solo) Model 2350 C engine. AD 2015- 09-04 R1 prohibits operation of the engine and requires performing a magnetic particle or dye penetrant inspection of the propeller shaft and reporting the results of the inspection to Solo. This proposed AD is prompted by 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 occurrences of rupture of the eccentric axle on Solo Model 2350 C engines (installed on DG Flugzeugbau GmbH Model DG- 1000T gliders in the United States) and an occurrence on a Solo Model 2350 D engine (installed on Schempp-Hirth Flugzeugbau GmbH (Schempp- Hirth) Model Duo Discus T gliders in the United States). This proposed AD would require repetitive replacement of the eccentric axle, would add the Schempp-Hirth Model Duo Discus T gliders to the applicability, and would retain from AD 2015-09-04 R1 the option of operating the glider with the engine non-operative instead of replacing the eccentric axle. The FAA is proposing this AD to address the unsafe condition on these products.
