ACTION: Final rule; request for comments. SUMMARY: 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. DATES: This AD is effective July 20, 2026. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 20, 2026. The FAA must receive comments on this AD by August 31, 2026. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to regulations.gov.
