The airworthiness directive

79-19-11 MCDONNELL DOUGLAS: Amendment 39-3564. Applies to McDonnell Douglas DC-10-10, -10F, -30, -30F and -40 airplanes certificated in all categories.

Compliance required within the next 350 hours' time-in-service after the effective date of this AD, unless already accomplished.

To eliminate the possibility of one side of the dual brake control valve jamming due to a separated improperly swaged retaining bolt collar accomplish the following:

(a) Inspect the nameplate on the dual brake control valves, located in the left and right wheel wells above and aft of the brake system accumulators, to ascertain whether valves were manufactured by Weston Hydraulics or McDonnell Douglas Astronautics Company. Valves manufactured by Weston Hydraulics Company require no further action.

(b) Modify and reidentify McDonnell Douglas Astronautics Company dual brake control valves in accordance with Subpart 2, Accomplishment Instructions of McDonnell Douglas DC-10 Service Bulletin No. A32-169, dated August 27, 1979.

(c) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections required by this AD.

(d) Alternative inspections, modifications or other actions which provide an equivalent level of safety may be used when approved by the Chief, Aircraft Engineering Division, FAA Western Region.

This amendment becomes effective September 24, 1979.
