Airworthiness Directives; Pratt & Whitney Canada Corp. Turboshaft Engines
The FAA is superseding Airworthiness Directive (AD) 2015-20-04 for certain Pratt & Whitney Canada Corp. (P&WC) PT6B-37A turboshaft engines. AD 2015-20-04 required initial and repetitive inspections until replacement of the No. 10 bearing, and eventual replacement of the No. 9 bearing, both located in the engine reduction gearbox (RGB) assembly. This AD requires removal from service and replacement of the No. 9 and No. 10 position bearings. This AD was prompted by reports of incorrect engine torque for PT6B-37A turboshaft engines. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA is superseding Airworthiness Directive (AD) 96-25-04, which applied to certain Airbus SAS Model A320 series airplanes. AD 96- 25-04 required repetitive inspections of the wire looms in the wing and the horizontal stabilizer and in certain areas of the main landing gear (MLG) bays; repair or replacement, protection, and realignment, if necessary; installation of protective sleeves; and realignment of certain bundles. This AD partially retains the requirements of AD 96-25-04 and requires modification of the wing electrical installation; as specified in a European Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a determination that there were issues with protective sleeves previously installed as specified in AD 96-25-04. The FAA is issuing 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 all Airbus SAS Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This AD was prompted by a quality control review, which determined that the wrong aluminum alloy was used to manufacture several structural parts. This AD requires a one-time eddy current conductivity measurement of certain structural parts of the outer flaps to determine if the incorrect alloy was used, and replacement if necessary, as specified in a European 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; Dassault Aviation Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This proposed AD was prompted by a determination 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. The FAA is proposing 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 787-8 airplanes. This proposed AD was prompted by a report of fatigue cracking at certain frame tie rod locations of the wing. This proposed AD would require repetitive inspections for cracking of the left- and right-side frame tie rod assemblies and stub beam upper chords, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Dassault Aviation Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2018-19-27 and AD 2014-16-12, which apply to certain Dassault Aviation Model FALCON 2000EX airplanes. Those ADs require revising the maintenance or inspection program, as applicable, to incorporate new maintenance requirements and airworthiness limitations. Since AD 2018- 19-27 and AD 2014-16-12 were 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. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA proposes to supersede Airworthiness Directive (AD) 2017-09-06, which applies to all General Electric Company (GE) GEnx-1B and GEnx-2B model turbofan engines. AD 2017-09-06 requires updating electronic engine control (EEC) full authority digital electronic control (FADEC) software and replacing a certain fan hub frame assembly part installed on GEnx-2B turbofan engines. Since the FAA issued AD 2017-09-06, GE has developed a design change to remove the unsafe condition. This proposed AD would require removal from service of certain EEC FADEC software on GEnx-1B and GEnx-2B model turbofan engines and would also require replacing the affected fan hub frame assembly booster outlet guide vanes. The FAA is proposing this AD to address the unsafe condition on these products.
