Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A319-151N and -153N; A320-251N, -252N, and -253N; and A321-251N, -252N, -253N, -251NX, -252NX, and -253NX airplanes. This AD was prompted by a report indicating that Kathon FP 1.5 biocide added to fuel and running through an airplane's engines can lead to engine performance degradation. This AD requires removing Kathon FP 1.5 biocide from the fuel tanks and engines and prohibits operation of an airplane with Kathon FP 1.5 biocide in a fuel tank or engine, as specified in a European Union Aviation Safety Agency (EASA) AD 2020- 0176, which is incorporated by reference. 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 certain Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report indicating that when the number 2 engine thrust reverser (T/R) was opened, the right-hand T/R hinge nut located at position 4 was found detached; investigation revealed that certain nuts could have been installed with noncompliant locking features, or with locking features that could degrade quicker than anticipated. This AD requires replacing any existing nut on the T/R hinge with a new nut, installing a new nut and washer if necessary, and applying a torque stripe at each T/R hinge location, 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 Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, and AS350D helicopters; Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters; and Model EC130 B4 and EC130 T2 helicopters. This proposed AD was prompted by a report of a missing retaining ring of the inner race of the main rotor mast (MRM) upper bearing. This proposed AD would require a one-time inspection to verify the presence and correct installation of the MRM upper bearing retaining rings, a repetitive inspection of the sealant bead on the MRM for damage, and corrective actions if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
Proposed Technical Amendment to Separate Terminal Airspace Areas from Norton Sound Low, Woody Island Low, Control 1234L, and Control 1487L Offshore Airspace Areas; Alaska
This action proposes to amend the following Offshore Airspace Areas in Alaska: Norton Sound Low, Woody Island Low, Control 1234L, and Control 1487L. The FAA found an error with the Offshore Airspace Legal Descriptions containing airspace descriptions not related to the need to apply IFR en route Air Traffic Control services in international airspace. This action would correct that error by removing terminal airspace, airspace associated with geographic coordinates, and airspace associated with NAVAIDs from the Offshore Airspace legal descriptions.
Airworthiness Directives; The Boeing Company Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, -200LR, and -300 series airplanes. This AD was prompted by the FAA's analysis of the Model 777 fuel system reviews conducted by the manufacturer. This AD requires modifying the fuel quantity indicating system (FQIS) to prevent development of an ignition source inside the center fuel tank due to electrical fault conditions. This AD also provides alternative actions for cargo airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
