Federal Aviation Administration March 2, 2021 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Airbus Helicopters
Document Number: 2021-03951
Type: Proposed Rule
Date: 2021-03-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model SA330J helicopters. This proposed AD was prompted by the failure of a second stage planet gear installed in the main gearbox (MGB). This proposed AD would require repetitively inspecting the MGB particle detector and the MGB bottom housing (oil sump) for metal particles, analyzing any metal particles that are found, and replacement of the MGB if necessary, as specified in a European Aviation Safety Agency (now 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.
Proposed Establishment of Area Navigation (RNAV) Routes T-322, T-392, T-403, and T-405; Central United States
Document Number: 2021-03931
Type: Proposed Rule
Date: 2021-03-02
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to establish area navigation (RNAV) routes T-322, T-392, T-403, and T-405 in the central United States. The proposed new RNAV routes would expand the availability of RNAV routing in support of transitioning the National Airspace System (NAS) from ground-based to satellite-based navigation. Additionally, a portion of the new RNAV routes would provide enroute structure where VHF Omnidirectional Range (VOR) Federal airway segments were removed due to the Sioux City, IA; Park Rapids, MN; and Huron, SD, VORs decommissioning in support of the FAA's VOR Minimum Operational Network (MON) program.
Airworthiness Directives; Airbus Helicopters
Document Number: 2021-03688
Type: Rule
Date: 2021-03-02
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding Airworthiness Directive (AD) 2015-26- 01, which applied to certain Airbus Helicopters Model AS332C1, AS332L1, AS332L2, EC225LP, AS-365N2, AS 365 N3, EC 155B, and EC155B1 helicopters with an energy-absorbing seat. AD 2015-26-01 required inspecting for the presence of labels (placards) that prohibit stowing anything under the seat, and if a label (placard) is missing or not clearly visible to each occupant, installing a label (placard). This AD retains all of the requirements of AD 2015-26-01, and also adds helicopters to the applicability and requires a modification (installing new labels (placards)). This AD was prompted by the determination that additional helicopters are affected by the unsafe condition, and that new labels (placards) are required for all affected helicopters. The FAA is issuing this AD to address the unsafe condition on these products.
