Federal Aviation Administration 2021 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and A350-1041 airplanes. This AD was prompted by reports that suitable corrosion protection treatment had not been applied to certain areas of the seat track. This AD requires a one-time detailed inspection of the seat tracks between certain frames for suitable corrosion protection or presence of corrosion, and on- condition actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to amend low altitude RNAV route T-207 in Florida. The proposed change would remove the Cecil, FL (VQQ), VOR from the route description due to the planned decommissioning of that VOR. The removal would not affect navigation along the route.

This action proposes to modify the Miami International Airport, FL (MIA) Class B airspace area to ensure the containment of aircraft conducting instrument procedures. The FAA is proposing this action to improve the flow of air traffic, enhance safety, and reduce the potential for midair collision in the MIA terminal area. This action also proposes changes to the MIA Class B airspace area to ensure the containment of arriving and departing aircraft within Class B airspace as required by FAA directives contained in FAA Order 7400.2M. This proposed action is separate and distinct from the Florida Metroplex Project.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model EC 155B, EC155B1, SA-365N, SA- 365N1, AS-365N2, and AS 365 N3 helicopters, as identified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD. This proposed AD was prompted by a report of an in-flight loss of engine and main gearbox (MGB) cowlings. This proposed AD would require inspecting the MGB fixed cowling front fitting (MGB front fitting), and depending on findings, corrective action. This proposed AD would also require a new modification, which would constitute a terminating action for the inspection. These proposed AD requirements are as specified in an 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 adopt a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters.

This proposed AD would require modifying certain side facing utility seats and observer seats. This proposed AD would also prohibit installing those seats unless the modification has been accomplished. The FAA is proposing this AD to address the unsafe condition on these products.

This notice announces a meeting of the ARAC.

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.

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.

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. The collection involves the submission of FAA Form 8710-3 for the certification process of agricultural aircraft operators, and other reporting and recordkeeping activities required of agricultural aircraft operators. The information to be collected is necessary to evaluate the applicants' qualifications for certification. This collection also involves the submission of information in petitions for exemption by agricultural aircraft operators, plans for operations over congested areas, and recordkeeping requirements for agricultural aircraft operators.

This action amends VHF Omnidirectional Range (VOR) Federal airways V-12, V-74, and V-516, in the vicinity of Anthony, KS. The modifications are necessary due to the planned decommissioning of the VOR portion of the Anthony, KS, VOR/Tactical Air Navigation (VORTAC) navigation aid (NAVAID), which provides navigation guidance for portions of the affected VOR Federal airways. The Anthony VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, AS 365 N3, EC 155B, and EC155B1 helicopters. This AD was prompted by the FAA's determination that to improve the process and performance in collecting metal particles in the main gear box (MGB) certain existing magnetic plugs (electrical and nonelectrical) installed in the MGB pump intake must be replaced with improved non-electrical magnetic plugs. This AD requires replacing the existing magnetic plug with an improved non- electrical magnetic plug, as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2018-05- 09, which applied to all Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2018-05-09 required inspecting the tail rotor (T/R) flapping hinge link (hinge) and reporting the results. This AD requires repetitive inspections of the spindle bolts and the inner ring and needle bearings of each flapping hinge, corrective actions if necessary, and repetitive replacements of affected flapping hinge components, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. Replacement of all affected flapping hinge components on each flapping hinge is terminating action for the repetitive inspections. This AD also expands the applicability. This AD was prompted by a report of a damaged flapping hinge on a T/R blade. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. (Leonardo) Model AB139 and AW139 helicopters.

The actions of this AD are intended to address an unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. (Leonardo) Model AW189 helicopters. This AD requires various repetitive inspections of the main rotor (MR) damper. This AD was prompted by reports of in-service MR damper failures and the development of an improved MR damper. This condition, if not corrected, could lead to loss of the lead-lag damping function of the MR blade, possibly resulting in damage to adjacent critical rotor components and subsequent loss control of the helicopter. The actions of this AD are intended to address the unsafe condition on these products.

The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to Robinson Helicopter Company (RHC) Model R22 series helicopters. The NPRM was prompted by an in-flight break up of a helicopter on which both teeter stop brackets (brackets) failed. The NPRM would have required replacing each main rotor blade (blade) droop and teeter stop (stop) and bracket and associated hardware with redesigned and improved airworthy parts. Since issuance of the NPRM, the FAA has determined that failure of the brackets was caused by turbulence and other factors that are addressed in AD 95-26-04. Accordingly, the NPRM is withdrawn.

This action amends the time of designation for restricted areas R-3008A, R-3008B, R-3008C, and R-3008D; Grand Bay Weapons Range, GA, by expanding the timeframe during which the areas may be activated without prior issuance of a Notice to Airmen (NOTAM). The expansion of the published designated times for these restricted areas reflects their routine actual use. This change better informs the flying public of actual routine use periods of the restricted areas and reduces NOTAM System workload.

The FAA is adopting a new airworthiness directive (AD) for certain 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 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 AD requires 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, this AD requires a protrusion check and a pull-out test, and the replacement of inserts on the HMU/MEC idler adapter that fail either test. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by reports of deficiencies in the primary flight control computer (PFCC) and remote electronics unit (REU) software. This proposed AD would require installation of a software update to correct deficiencies in the PFCC and REU software, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes.

The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 727 series airplanes. This AD was prompted by a determination that excessive sealant coating on internal wing Structural Significant Items (SSIs) may not reveal cracks during inspections required by AD 98-11-03 R1. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate inspections that will give no less than the required damage tolerance rating (DTR) for certain SSIs of the wing. This AD also requires repetitive inspections for cracking of the affected SSIs and repair if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is revising an earlier proposal for certain The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding airplanes to the applicability and proposing to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. 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 that in the NPRM, the FAA is reopening the comment period to allow the public the chance to comment on these changes.

The FAA proposes to supersede Airworthiness Directive (AD) 2019-22-07, which applies to all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. AD 2019-22-07 requires revising the existing airplane flight manual (AFM) to include a limitation and an abnormal operating procedure for the Automatic Flight Control System (AFCS). Since the FAA issued AD 2019-22-07, it was found that the limitation and abnormal operating procedure did not include reference to a certain mode. This proposed AD would require revising the existing AFM and adding airplanes to the applicability. 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 Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed AD was prompted by reports of DC motor pump (DCMP) failures during production flight tests. This proposed AD would require installing a redesigned DCMP electric motor assembly. The FAA is proposing this AD to address the unsafe condition on these products.
