New Delhi, India (PTI) Dec 08, 2006 An expert committee probing the crash of a satellite launch vehicle on July 10 this year has recommended "very stringent" quality checks on the supplied components, Rajya Sabha was informed Friday. Minister of State in the Prime Minister Office, Prithviraj Chavan, said the explosion in Geo-Stationary Launch Vehicle (GSLV), which was to put INSAT-4C communication satellite into the orbit, resulted in a loss of Rs 256 crore. The primary cause of mission failure was attributed to the loss of thrust in one liquid strap-on motor due to malfunctioning of propellent regulator. The entire engine system, including propellent regulator, is procured from the industry as per the Indian Space Research Organisation (ISRO) design at a cost of Rs 120 lakh per engine, Chavan said. "The propellent regulator is a complex and high precision device, and some of its critical dimensions can be checked at the stage of manufacture only. As the manufacturer's log book did not indicate the deviation in dimension, it went unnoticed," he said. "Over the past several years, nearly 50 engine systems have been successfully realised in Indian industries and have been put to use in flight as well as ground tests," he added.
