Airworthiness Directives; McDonnell Douglas Model 717-200 Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires repetitively replacing and testing a certain relay in the passenger oxygen release system in the forward cabin. This AD results from reports of a failed relay in the passenger oxygen release system. We are issuing this AD to prevent failure of the relay, which could result in the oxygen masks failing to deploy and deliver oxygen to the passengers in the event of a rapid decompression or cabin depressurization.
