Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes

本地自动翻译 · 来源原始语言

摘要

The FAA is revising a notice of proposed rulemaking (NPRM) that would have applied to certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12 airplanes. This action revises the NPRM by changing the applicability. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM for different airplanes, the FAA is requesting comments on this SNPRM.

Airworthiness Directives; Diamond Aircraft Industries Inc. Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for certain Diamond Aircraft Industries Inc. (DAI) Model DA20-C1 airplanes. This proposed AD was prompted by a report of a certain emergency locator transmitter (ELT) not activating due to a missing jumper wire. This proposed AD would require a continuity inspection of the D-sub connector of the Artex ELT 1000 and, if necessary, corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus SAS Airplanes

The FAA is superseding Airworthiness Directive (AD) 2025-03- 07, which applied to certain Airbus SAS Model A318, A319, and A320 series airplanes; and Model A321-111, -112, -131, -211, -212, -213, - 231, -232, -251N, -252N, -253N, -271N, -272N, -251NX, -252NX, -253NX, - 271NX, and -272NX airplanes. AD 2025-03-07 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2025-03-07, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2025-03-07 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, and expands the applicability. The FAA is issuing 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.

Since the FAA issued AD 2023-20-05, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023-20-05 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Airbus SAS Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-841 and Model A330-941 airplanes. This proposed AD was prompted by reports of crack findings on the sloping rib. This proposed AD would require a repetitive inspection of the external surface of each sloping rib and each slat 1 inboard seal, and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
