Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A319-113 and -114 airplanes, and Model A320-211 and - 212 airplanes. This AD was prompted by a report that a life-limit of 64,000 flight cycles has been established for certain titanium crossbeams of the forward engine mount. This AD requires repetitive replacements of all affected crossbeams of the forward engine mount, as specified in European Aviation Safety Agency (EASA) ADs, which are 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 is superseding Airworthiness Directive (AD) 2017-16- 10, which applied to all The Boeing Company Model 777 airplanes. AD 2017-16-10 required repetitive inspections of the left and right side underwing longerons for any crack, and related investigative and corrective actions if necessary. This AD retains the requirements of AD 2017-16-10, reduces certain compliance times for certain airplanes, and removes airplanes from the applicability. This AD was prompted by reports of cracks on the underwing longerons. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; CFM International S.A. Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) 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. This AD requires 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. The FAA is issuing this AD to address the unsafe condition on these products.
