Airworthiness Directives; Diamond Aircraft Industries Inc. Airplanes

Built by the Tribune's code from the Federal Register. No AI wrote this page. Published in the Federal Register May 15, 2026. Document 2026-09772. Updated Nov. 11, 2026.

What it does

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.
