Airworthiness Directives; CFM International, S.A. Turbofan Engines
The FAA is superseding Airworthiness Directive (AD) 2019-12-05 for certain CFM International S.A. (CFM) CFM56-5B, CFM56-5C, and CFM56- 7B model turbofan engines with a certain rotating air high-pressure turbine (HPT) front seal. AD 2019-12-05 required replacement of the affected rotating air HPT front seal with a part eligible for installation. This AD was prompted by cracks found in the rotating air HPT front seal. This AD requires replacement of affected rotating air HPT front seals installed on CFM CFM56-5B, CFM56-5C, and CFM56-7B model turbofan engines that have fewer cycles since being reconfigured than the engines affected by AD 2019-12-05. This AD also requires CFM56-5B or CFM56-7B model turbofan engines with a reconfigured rotating air HPT front seal that was previously operated in a CFM56-5C model turbofan engine to follow the removal requirements for the CFM56-5C model turbofan engine. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-10E model turbofan engines. This proposed AD was prompted by a manufacturer investigation that revealed Teflon material in the A-sump oil strainer (strainer assembly) screen after several reports of in-flight shutdowns (IFSDs) and unscheduled engine removals (UERs). This proposed AD would require initial and repetitive visual inspections of the strainer assembly screen. As a terminating action to the initial and repetitive visual inspections, this proposed AD would require the replacement of the stationary oil seal at the No. 1 forward bearing. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; De Havilland Aircraft of Canada Limited (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for De Havilland Aircraft of Canada Limited Model DHC-8-401 and -402 airplanes. This proposed AD was prompted by reports of a possible hard contact between the #2 top high level sensor (HLS) terminal screw head and the #6 outer wing fuel access panel stiffener flange. This proposed AD would require removing and replacing or reworking the #6 outer wing fuel access panel assembly. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2018-19-28, which applies to certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes; and AD 2014-16-16, which applies to all of those airplane models. AD 2014-16-16 requires, for certain airplanes, retorquing and replacing the pylon lower link fittings, and for all airplanes, repetitively retorquing those fittings. AD 2018-19-28 requires modifying the attaching parts of the pylon lower link fittings. Since the FAA issued AD 2014-16-16 and AD 2018-19-28, the FAA finds it necessary to change the compliance time for the modification. This proposed AD would require an inspection of certain shear pins, replacement if necessary, and revised compliance times for the modification, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) 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 SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, - 113, -114, -115, -131, -132, -133, -151N, and -153N airplanes; Model A320 series airplanes; and Model A321 series airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires 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 is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Defense and Space S.A. (Formerly Known as Construcciones Aeronauticas, S.A.) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Defense and Space S.A. Model C-212-CB, C-212-CC, C-212- CD, C-212-CE, C-212-CF, C-212-DE, and C-212-DF airplanes. This AD was prompted by a report of cracks on the left-hand (LH) and right-hand (RH) side fuselage skin and on a certain frame underneath the skin, near the leading edge of the wing. This AD requires repetitive inspections of the LH and RH side center wing fairings at a certain frame, around the wing leading edge for discrepancies (cracks), and repair 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.
Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-300, -400, and -500 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the frame splice between certain stringers is subject to widespread fatigue damage (WFD). This proposed AD would require an inspection of certain fuselage frame splices for existing repairs, repetitive inspections of certain fuselage frame splices for cracking, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2017-23-02, which applies to certain The Boeing Company Model 737-200, -200C, -300, -400, and -500 series airplanes. AD 2017-23-02 requires repetitive inspections, replacement, and applicable on-condition actions for certain fuselage crown skin panels. Since the FAA issued AD 2017-23-02, certain airplane configurations and inspection locations have been revised and additional airplanes have been determined to be subject to the unsafe condition. This proposed AD would retain the actions in AD 2017-23-02, revise certain airplane configurations and inspection locations, and add airplanes to the applicability. The FAA is proposing this AD to address the unsafe condition on these products.
Safety Management System for Certificated Airports
This action reopens the comment period for the Safety Management System for Certificated Airports SNPRM published July 14, 2016. In the SNPRM, the FAA proposed to amend certain requirements included in the notice of proposed rulemaking published on October 7, 2010. Most notably, the FAA revised the proposed applicability of the rule so that a Safety Management System (SMS) is only required for a certificated airport classified as a small, medium, or large hub airport in the National Plan of Integrated Airport Systems; serving international air traffic; or having more than 100,000 total annual operations. The FAA also proposed changes that would extend the implementation period from 18 to 24 months; require submission of an implementation plan within 12 months instead of 6 months of the effective date of the final rule; modify the training requirements; ensure consistency among various FAA SMS initiatives, and reduce the implementation burden.
