Within the next 1,200 hours time-in-service or six (6) months after the effective date of this AD, whichever comes first, unless already accomplished, replace the straight orifice fittings on the Boeing part number 10-60513-18, -19, and -20 latch valves and manifold assemblies of the PSU with the redesigned barbed orifice fitting and O-ring in accordance with Boeing Service Bulletin 727-35-A18 dated July 6, 1979, or Boeing Service Bulletin 737-35-A1014 dated July 6, 1979, as applicable, and Puritan-Bennett Service Letter 210780-35-1 dated May 25, 1979, or later FAA-approved revisions.

The compliance time prescribed above may be extended to 2,400 hours time-in-service or one (1) year after the effective date of this AD, whichever comes first, by limiting the operational altitude of the airplane to 25,000 feet.
The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1).
