Agency Information Collection Activities: Requests for Comments; Clearance of a New Approval of Information Collection: Operational Waivers for Small Unmanned Aircraft Systems
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 for a new information collection. The FAA proposes collecting information about requests for waivers from certain operational rules that apply to small unmanned aircraft systems (sUAS). The FAA will use the collected information to make determinations whether to authorize or deny the requested operations of sUAS. The proposed information collection is necessary to issue such authorizations or denials consistent with the FAA's mandate to ensure safe and efficient use of national airspace.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all General Electric Company (GE) CF6-80C2A1, CF6-80C2A2, CF6- 80C2A3, CF6-80C2A5, CF6-80C2A5F, CF6-80C2A8, CF6-80C2B1, CF6-80C2B1F, CF6-80C2B2, CF6-80C2B2F, CF6-80C2B4, CF6-80C2B4F, CF6-80C2B5F, CF6- 80C2B6, CF6-80C2B6F, CF6-80C2B6FA, CF6-80C2B7F, CF6-80C2B8F, and CF6- 80C2D1F model turbofan engines. This proposed AD was prompted by reports of incidents that resulted in a significant fuel loss during flight and an in-flight shutdown (IFSD) of the engine. This proposed AD would require initial and repetitive shim checks of the hydromechanical unit/main engine control (HMU/MEC) idler adapter on the accessory gearbox (AGB) assembly and, depending on the results of the shim check, possible replacement of the inserts on the HMU/MEC idler adapter. As a terminating action to the repetitive shim checks, this proposed AD would also require a protrusion check and a pull-out test and replacements of inserts on the HMU/MEC idler adapter that fail either test. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A320-214, -216, -231, -232, -233, -251N, and -271N airplanes. This proposed AD was prompted by a report that following the installation of a second cargo fire extinguishing bottle, insufficient clearance between the cargo compartment fire extinguishing pipes was found. This proposed AD would require inspection and modification of the cargo compartment fire extinguishing pipes, and on- condition actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2016-18-09, which applies to certain Airbus SAS Model A318, A319, and A320 series airplanes. AD 2016-18-09 requires repetitive detailed inspections for damage on the fuselage skin at certain frames, and applicable related investigative and corrective actions. Since the FAA issued AD 2016-18-09, additional chafing of the forward fuselage underneath the fairing structure was found. Investigation revealed the cause as contact between the belly fairing nut plate and the fuselage. This proposed AD would continue to require repetitive inspections of the fuselage skin for chafing damage at certain frames using a new inspection process, and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2019-03-11, which applies to certain Airbus SAS Model A350-941 and - 1041 airplanes. AD 2019-03-11 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. Since AD 2019-03-11 was issued, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain 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. This proposed AD was prompted by reports of crack findings in and around the fastener holes of the central and lateral window frame upper junction; those cracks were found on fastener holes outside of the inspection area specified in a certain airworthiness limitation item (ALI) task. This proposed AD would require repetitive inspections of the upper junction fastener holes at the lateral window frame for cracking; and for certain airplanes, repetitive inspections of the spotface around the fastener holes for cracking; and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-1A, CF34-3A, CF34-3A1, CF34- 3A2, CF34-3B, and CF34-3B1 model turbofan engines. This AD was prompted by an in-flight failure of a fan blade that led to an in-flight shutdown. This AD requires removal and replacement of the affected fan blades. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd. & Co KG Trent 1000-A2, Trent 1000- AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000-K2, and Trent 1000-L2 model turbofan engines. This proposed AD was prompted by the manufacturer revising the engine Time Limits Manual (TLM) life limits of certain critical rotating parts and direct accumulation counting (DAC) data files. This proposed AD would require operators to revise the airworthiness limitation section (ALS) of their approved maintenance program by incorporating the revised tasks of the applicable TLM for each affected engine model. The FAA is proposing this AD to address the unsafe condition on these products.
