Airworthiness Directives; Diamond Aircraft Industries Inc. (Type Certificate Previously Held by Diamond Aircraft Industries GmbH) Airplanes
The FAA is superseding Airworthiness Directive (AD) 2009-10-04 for certain Diamond Aircraft Industries GmbH (type certificate now held by Diamond Aircraft Industries Inc.) Model DA 40 and DA 40 F airplanes. AD 2009-10-04 required repetitively inspecting the nose landing gear (NLG) leg for cracks and replacing the NLG leg if cracks are found. Since the FAA issued AD 2009-10-04, Transport Canada updated mandatory continuing airworthiness information (MCAI) to correct this unsafe condition on these products. This AD results from changes made to the part replacement options and the repetitive inspections. This AD requires doing repetitive detailed inspections of the NLG leg pivot axle for cracking and if cracking is found replacing that part with a serviceable part. This AD also requires eventually replacing all NLG legs having certain part numbers with serviceable parts, if not already done, and prohibits installing affected parts. Replacing affected parts with serviceable parts is terminating action for the repetitive inspections specified in this AD. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Various Helicopters
The FAA is superseding Airworthiness Directive (AD) 2024-01- 11, which applied to all helicopters with certain Pacific Scientific Company rotary buckle assemblies (buckles) installed. AD 2024-01-11 required inspecting the buckle screws and, depending on the results, reidentifying the buckle, replacing the screws and reidentifying the buckle, or replacing the buckle. AD 2024-01-11 also prohibited installing certain buckles. This AD retains the requirements of AD 2024-01-11, expands the applicability, and updates the referenced material. As an option to the actions required by this AD, this AD allows removing the male side from the lap of the restraint system assembly and installing a placard stating that use of the seat is prohibited; use of that crewmember seat or passenger seat is then prohibited until the actions required by the AD are accomplished and the male side from the lap of the restraint system assembly is reinstalled. This AD was prompted by a manufacturing defect in the screws used inside the buckle. The FAA is issuing this AD to address the unsafe condition on these products.
