Compliance required as indicated.

There have been instances in which the emergency airbrake handle shaft became disengaged from the remaining portion of the system. This condition may go undetected until the system use is required, therefore, accomplish the following on airplanes which have not been modified in accordance with Douglas DC-8 Service Bulletin 32-62 dated September 14, 1961, or its production equivalent, or an equivalent approved by the Aircraft Engineering Division, FAA Western Region.

(a) Within 150 hours' time in service after the effective date of this AD, inspect the emergency airbrake control linkage shaft assembly Douglas P/N 4644428 in accordance with paragraph 2A of Douglas Alert Service Bulletin A32-62, Reissue No. 1 dated October 9, 1961.

(b) If it is determined from the inspection that there is insufficient engagement of the emergency airbrake control linkage shaft assembly, modify the system before further flight in accordance with Douglas DC-8 Alert Service Bulletin A32-62, Reissue No. 1 dated October 9, 1961, or Douglas DC-8 Service Bulletin 32-62 dated September 14, 1961, or an equivalent approved by the Aircraft Engineering Division, FAA Western Region.

(c) If it is determined from the inspection that there is sufficient engagement of the emergency airbrake control linkage shaft assembly, or if Douglas DC-8 Alert Service Bulletin A32-62 is used in making the modification in accordance with paragraph (b), reinspect the emergency brake control shaft in accordance with paragraph 2A of Douglas Alert Service Bulletin A32-62, Reissue No. 1 dated October 9, 1961, each time after the glare shield or the panel supporting the emergency airbrake handle is installed or after maintenance is performed behind the instrument panel in the area of the emergency airbrake control linkage shaft assembly.

(d) The repetitive inspections required in paragraph (c) may be discontinued when the emergency airbrake control shaft assembly is modified in accordance with Douglas DC-8 Service Bulletin 32-62 dated September 14, 1961, or an equivalent approved by the Aircraft Engineering Division, FAA Western Region.

(Douglas DC-8 Service Bulletin 32-62 dated September 14, 1961, and Douglas DC-8 Alert Service Bulletin A32-62, Reissue No. 1 dated October 9, 1961, apply to this same subject.)
