AD 2026-14-08 Airworthiness Directives; Diamond Aircraft Industries GmbH
Makes named: diamond. Models named: DA 42, DA 42 M-NG, DA 42 NG. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all Diamond Aircraft Industries GmbH (DAI) Model DA 42, DA 42 M-NG, and DA 42 NG airplanes, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
For the purpose of this AD, the following definitions apply: (1) An “affected part” is an NLG hydraulic actuator rod end having part number (P/N) X11-0006-SMRCD10IRMR.7403 or P/N X11-0006-GARSW-10RR. (2) A “serviceable part” is an affected part that is new (never previously installed on an airplane) or that, before installation, has been inspected and corrected as required by paragraphs (h)(2) and (3) of this AD. (3) A “flight cycle” is defined as one takeoff and one landing. Each additional takeoff and landing associated with a touch-and-go, or a go-around, is accounted for as an additional take-off and landing.
Unsafe condition
This AD was prompted by occurrences of uncommanded rudder deflection caused by a cracked nose landing gear (NLG) hydraulic actuator rod end. The FAA is issuing this AD to prevent cracked rod ends from leading to the failure of the NLG actuator and interference with the rudder control system. The unsafe condition, if not addressed, could result in restricted rudder travel in the landing gear retracted configuration and result in reduced control of the airplane.
Affected ADs
None.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
