Airworthiness Directives; Airbus Helicopters

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, EC130B4, and EC130T2 helicopters. This proposed AD was prompted by reports of an incorrectly installed engine flange on the main gear box (MGB) engine coupling. This proposed AD would require inspecting the MGB engine coupling for correct installation and, depending on the results, corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus Helicopters

The FAA proposes to supersede Airworthiness Directive (AD) 2023-25-14, which applies to certain Airbus Helicopters Model EC130T2 helicopters. AD 2023-25-14 revises the procedures for inspecting the vibration level on the tail rotor drive shaft and, depending on these results, requires replacing certain parts. Since the FAA issued AD 2023-25-14, the manufacturer developed a modification of the rear drive shaft, sliding flange and equipped splined sleeve. This proposed AD would require installing this modification and repetitively inspecting the vibration level of the tail rotor drive shaft. This proposed AD would also prohibit the installation of certain parts and prohibit the performance of a balance correction unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Bell Textron Canada Limited Helicopters

The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited (BTCL) Model 407 helicopters. This AD was prompted by a determination that chafing can occur at various locations on the electrical harnesses located in the aircraft instrument panel area. This AD requires a one-time detailed visual inspection of the electrical harnesses for chafing and corrective actions if necessary. This AD also requires rotation of the backshell cast housing of connectors of the lower engine airframe unit and installation of a wire harness bracket and support, and for certain helicopters, installation of a wire bundle sleeve. 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 A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320 series airplanes; and Model A321-211, - 212, -213, -231, -232, -251N, -251NX, -252N, -252NX, -253N, -253NX, - 271N, -271NX, -272N, and -272NX airplanes. This AD was prompted by a review of the cold working process on the assembly line that detected a deviation to the manufacturing process. This AD requires repetitive inspections for the nominal design condition of the fastener holes in the pressure deck membrane to center wing box attachment and, as applicable, an inspection for cracking at the affected area and corrective actions. 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 A330-200 series airplanes; Model A330-200 Freighter series airplanes; Model A330-300 series airplanes; and Model A330-841 and -941 airplanes. This AD was prompted by a report of an in-service event and relevant investigation which found that, under specific conditions, a dormant failure of a standby fuel pump could lead to a certain amount of fuel being trapped in the aft section of the inner tank that would be unusable. This AD requires repetitive operational checks of the standby fuel pumps and corrective actions and limits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Leonardo S.p.a. Helicopters

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AB139, AW139, and AW189 helicopters. This AD was prompted by a report of cracks on the left-hand (LH) and right-hand (RH) tube assemblies installed on the brake pedal assemblies. This AD requires repetitively inspecting the LH and RH tube assemblies for Model AB139 and AW139 helicopters, and the LH and RH pedal shaft assemblies for Model AW189 helicopters, and depending on the results of the inspection, corrective actions. This AD also prohibits installing certain parts unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
