Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by a report that during a C- check, corrosion was found in the vertical fin tension bolt hole located in the aluminum crown frames at Section 48. This proposed AD would require inspecting certain vertical fin tension bolt holes; reviewing the bolt sealant application installation procedure in the existing maintenance or inspection program, as applicable; checking maintenance records to determine the replacement status of vertical fin tension bolts; and doing applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
Amendment of VOR Federal Airways V-170, V-175 and V-250; Establishment of Area Navigation (RNAV) Route T-400; in the Vicinity of Worthington, MN.
This action changes the effective date of a final rule published in the Federal Register on January 14, 2022, amending VHF Omnidirectional Range (VOR) Federal airways V-170, V-175, and V-250, and establishing area navigation (RNAV) route T-400, due to the planned decommissioning of the VOR portion of the Worthington, MN, VOR/Distance Measuring Equipment (VOR/DME) navigational aid. The FAA is delaying the effective date to facilitate continued use of the current Air Traffic Procedures, while allowing sufficient time for redesign of the proposed procedures, in order to meet to required current procedure criteria.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-2 helicopters. This proposed AD was prompted by a report of restricted collective lever movement caused by entanglement of the emergency flashlight strap with the cargo hook emergency release lever, causing the emergency flashlight to leave its seat. This proposed AD would require replacing each affected emergency flashlight with a serviceable part, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332L2 and EC225LP helicopters. This AD was prompted by a report of loss of tightening torque on the nut that attaches the tail gear box (TGB) bevel wheel. This AD requires repetitive inspections (measurements) of the angular clearances of the TGB, and, depending on the findings, replacement of the TGB with a serviceable TGB, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also provides terminating action for certain repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.
Modification of Class E Airspace; Kit Carson County Airport, Burlington, CO
This action modifies the Class E airspace extending upward from 700 feet above the surface of the Earth, and removes the Class E airspace extending upward from 1,200 feet above the surface of the Earth at Kit Carson County Airport, Burlington, CO. This action ensures the safety and management of instrument flight rules (IFR) operations at the airport.
Agency Information Collection Activities: Requests for Comments; Clearance of Renewed Approval of Information Collection: Certification: Pilots and Flight Instructors
In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request Office of Management and Budget (OMB) approval to renew an information collection. FAA regulations prescribe certification standards for pilots, flight instructors, and ground instructors. The information collected is used to determine compliance with applicant eligibility.
Airworthiness Directives; CFM International, S.A. Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all CFM International, S.A. (CFM) LEAP-1B21, LEAP-1B23, LEAP-1B25, LEAP-1B27, LEAP-1B28, LEAP-1B28B1, LEAP-1B28B2, LEAP-1B28B2C, LEAP- 1B28B3, LEAP-1B28BBJ1, and LEAP-1B28BBJ2 model turbofan engines. This proposed AD was prompted by the detection of melt-related freckles in the billet, which may reduce the life of certain compressor rotor stages 6-10 spools, high pressure turbine (HPT) rotor mid seals, HPT rotor stage 2 disks, low pressure turbine (LPT) stage 2 disks, and LPT stage 3 disks. This proposed AD would require revising the airworthiness limitations section (ALS) of the applicable CFM LEAP-1B Engine Shop Manual (ESM), and the operator's existing approved continuous airworthiness maintenance program (CAMP) to incorporate reduced life limits for these parts. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; CFM International, S.A. Turbofan Engines
The FAA is superseding Airworthiness Directive (AD) 2013-26-01 for all CFM International, S.A. (CFM) CFM56-3 and CFM56-7B model turbofan engines with a certain accessory gearbox assembly (AGB) not equipped with a dynamic oil seal assembly in the handcranking pad. AD 2013-26-01 required an independent inspection to verify re-installation of the handcranking pad cover after removal of the pad cover for maintenance. This AD was prompted by a dual engine loss of oil event and 42 prior events of total loss of engine oil during flight. This AD requires independent inspection to verify re-installation of the AGB handcranking pad cover after maintenance. This AD also requires the replacement of the affected AGB as a terminating action to the inspection requirement. The FAA is issuing this AD to address the unsafe condition on these products.
