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