Analysis
As the Mcdonnell Douglas DC8 crew bgn the after lndg check, a decrease in qnty of hyd pres was noted. The capt elected to leave the flaps extdd, though the spoilers were retracted. Hyd pres rmnd nml & the crew contd to the ramp. While taxiing, the qnty suddenly went to zero; the nosewheel steering & nml brakes bcm inop. Atmts to stop by using emerg pneumatic braking were unsuccessful. The capt tried to reverse thrust fm #2 & #3 engs, but they would not reverse (#1 & #4 engs were shut dwn). The acft was on a slope; it subsequently rolled into a Boeing 727. An exam revealed the bogie trim cyl, pn 5616554-5503, on the l main lndg gear had ruptured. The air bottle for pneumatic braking was charged to operg pres, but movement of the airbrake lever would not oper the ctl vlv, pn 25600-5001; though no anomalies were fnd in rigging/alignment. Manufacturer didn't provide a rcmdd interval for checking the pneumatic braking sys, but the oper-ator checked it at 25,000 hr (d-check) intervals; the acft had been operd 19,339 hrs, since the vlv was last checked.
