PRODUCT: Certain Boeing 737-600, -700, -700C, -800, -900, and -900ER series airplanes. SUBJECT: Airworthiness Directive AD 2012-25-05 ACTION: Final Rule
SUMMARY: This AD was prompted by reports of escape slides failing to deploy from the forward and aft right-hand doors during scheduled maintenance slide deployments.
This AD requires modifying the escape slide. Also, for certain airplanes, this AD requires modifying or replacing the Vespel piston. For certain other airplanes, this AD requires an additional modification of the escape slide.
The FAA is issuing this AD to prevent failure of an escape slide to deploy, which could result in the slide being unusable during an emergency evacuation and increased likelihood of injury to passengers or crewmembers due to the difficulty in evacuating the airplane.
