Nov 28 1979
From The Space Library
NASA said the launch of a FltSatCom scheduled for December 4 had been postponed to January 1980. A leak in the Atlas vehicle's highpressure pneumatics system detected during routine testing November 26 was traced to a cracked sleeve and nut assembly; defective parts were removed and replaced. Analysis of the sleeve showed that it had been made from stainless steel that did not meet specifications; NASA immediately began investigating all similar sleeves on the launch vehicle and made changes as necessary. Investigation revealed that the problem was more serious: other sleeves located in stock did not meet specifications, and NASA now planned to check all appropriate fittings on the launch vehicle.
