Airworthiness Directive · Amendment 39-23409 · Diamond Aircraft Industries GmbH Airplanes
Diamond Aircraft Industries GmbH Airplanes
This AD applies to Diamond Aircraft Industries GmbH DA 42, DA 42 M-NG, DA 42 NG.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
The FAA is adopting a new airworthiness directive (AD) for all Diamond Aircraft Industries GmbH (DAI) Model DA 42, DA 42 NG, and DA 42 M-NG airplanes. This AD was prompted by occurrences of uncommanded rudder deflection caused by a cracked nose landing gear (NLG) hydraulic actuator rod end, which could lead to failure of the NLG actuator and interference with the rudder control system, forcing the rudder into left-hand deflection. This AD requires revising the existing airplane flight manual (AFM) for your airplane to provide the flight crew with revised operating limitations, repetitively inspecting certain NLG hydraulic actuator rod ends for cracks, deformation, corrosion, damage, and free movement of the spherical bearing, and depending on the results of any inspection, replacing the affected NLG hydraulic actuator rod end with a serviceable part. This AD also prohibits the installation of an affected NLG hydraulic actuator rod end unless certain conditions are met. The FAA is issuing this AD to address the unsafe condition on these products.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
