Federal Aviation Administration – Federal Register Recent Federal Regulation Documents

The FAA is withdrawing the NPRM published in the Federal Register on December 28, 2018, proposing to amend United States Area Navigation (RNAV) route T-299, and establish T-318 and T-360 in support of transitioning the National Airspace System (NAS) from ground-based to satellite-based navigation.

This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This proposed AD was prompted by a report that some of the multi-function spoiler (MFS) anti-rotation plates failed in-service due to a thin wall design. This proposed AD would require replacing the MFS anti-rotation plates, inspecting the MFS anti-rotation plates for cracking and hinge bolts for evidence of rotation, accomplishing applicable corrective actions, and performing a functional test of the multi-function spoiler control surfaces. 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 Airbus SAS Model A350-941 airplanes. This proposed AD was prompted by a report the axis index washers on the forward and rear main landing gear door hinges were found inverted in production. This proposed AD would require a one-time detailed inspection of the axis index washers for correct installation, and, depending on findings, replacement of the axis index washers, 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 proposes to supersede Airworthiness Directive (AD) 2021-21-13, which applies to certain Rolls-Royce Deutschland Ltd. & Co KG (RRD) Model Trent 1000 engines. AD 2021-21-13 requires the operator to revise the airworthiness limitation section (ALS) of their existing approved aircraft maintenance program (AMP) by incorporating the revised tasks of the applicable time limits manual (TLM) for each affected model turbofan engine. Since the FAA issued AD 2021-21-13, the manufacturer has revised the TLM, introducing new and more restrictive instructions. This proposed AD would require revisions to the ALS of the operator's existing approved AMP, 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.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Austro Engine GmbH Model E4 and E4P engines. This proposed AD was prompted by reports of piston failures and the determination that certain batches of pistons were manufactured with a dimensional deviation in the piston pin bore and piston diameter. This proposed AD would require repetitive engine oil analysis for aluminum content outside the acceptable limits and, if necessary, replacement of the pistons, piston rings, con-rods assembly, and crankcase or, as an alternative, replacement of the engine core. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2019-07-05, which applies to all Airbus SAS Model A318 series 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 2019-07-05 requires repetitive inspections for cracking of the 10VU rack fitting lugs and repair of any cracking. Since the FAA issued AD 2019-07-05, it was determined that certain repetitive inspection intervals need to be revised. This proposed AD would retain the requirements of AD 2019-07-05, with reduced compliance times and would remove airplanes having a certain modification from the applicability. The FAA is proposing this AD to address the unsafe condition on these products.
