The airworthiness directive
76-01-10 MCDONNELL DOUGLAS: Amendment 39-2493. Applies to all Douglas Model DC-10-10, -10F, -30, -30F, and -40 Series airplanes certificated in all categories, incorporating Bertea Corporation P/N 216000-5001 through -5013 inboard elevator actuator assemblies with serial numbers 240 through 500 inclusive.
Compliance required within the next 1500 hours' time in service after the effective date of this AD, unless already accomplished.
To prevent jamming of inboard elevator surfaces accomplish the following:
(a) Inspect the inboard elevator actuator manifold assemblies for interference between the internal control linkage and the manifold, and rework, if required, in accordance with Bertea Service Bulletin No. 27-48, Revision 1, dated October 9, 1975, or later FAA-approved revisions, or an equivalent inspection and rework procedure approved by the Chief, Aircraft Engineering Division, FAA Western Region. (Douglas Service Bulletin No. 27-141, dated October 10, 1975, calls attention to the Bertea service bulletin).
(b) Special flight permits may be issued per FAR's 21.197 and 21.199 to operate airplanes to a base for the accomplishment of this AD.
