Airworthiness Directive · Amendment 39-17286 · Equipment/furnishings
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, certificated in any category, with Goodrich Corporation door escape slide part number (P/N) 5A3307-1, -3, -5, or -301, serial numbers (S/N) BNG0001 through BNG14499 inclusive.
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. 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. We are 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.
Within 36 months after the effective date of this AD: Modify the escape slide, in accordance with the Accomplishment Instructions of Goodrich Service Bulletin 5A3307-25-389, Revision 2, dated May 4, 2012.
(1) For slide P/N 5A3307-301: Prior to or concurrently with accomplishing the actions required by paragraph (g) of this AD, modify the escape slide, in accordance with the Accomplishment Instructions of Goodrich Service Bulletin 5A3307-25-339, Revision 5, dated May 4, 2012.
(2) For slide P/N 5A3307-301 or 5A3307-5: Prior to or concurrently with accomplishing the actions required by paragraph (g) of this AD, modify the Vespel piston in the regulator valves, or replace the Vespel piston with a new or serviceable Vespel piston P/N 3A3566-2 or 3A3832-2, as applicable, in accordance with the Accomplishment Instructions of Goodrich Service Bulletin 25-349, Revision 1, dated January 11, 2010.
