Airworthiness Directive 2008-18-06
one-timeAirworthiness Directives; McDonnell Douglas Model DC-9-10, DC-9-20, DC-9-30, DC-9-40, and DC-9-50 Series Airplanes, Equipped With a Tail Cone Evacuation Slide Container Installed in Accordance With Supplemental Type Certificate (STC) ST735SO
What this AD requires
We are adopting a new airworthiness directive (AD) for McDonnell Douglas Model DC-9-10, DC-9-20, DC-9-30, DC-9-40, and DC-9-50 series airplanes, equipped with tail cone evacuation slide containers as specified above. This AD requires modifying the tail cone slide. This AD also requires additional tail cone drops and slide deployments, and repair if necessary. This AD results from several reports of inadvertent tail cone deployments in which the tail cone slide failed to deploy. We are issuing this AD to ensure that the tail cone evacuation slide deploys correctly. Failure of the slide to deploy during an emergency evacuation could result in injury to flightcrew and passengers.
Which aircraft AD 2008-18-06 applies to
Whether AD 2008-18-06 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
