Cargo spacecraft crashed because of fuel supply problem

MOSCOW, September 9 (Itar-Tass) -- The Progress cargo spacecraft
crashed in August because of a fuel supply problem in the third stage of
the Soyuz booster, the Roskosmos space agency said late on Thursday
quoting the results of an investigation by a government commission.
It said the fuel supply tract to the gas generator of the third stage
was choked up due to a production fault.
"The analysis of the operating parameters of the third stage engine
and the results of telemetric information provided a conclusion about
decreased fuel consumption in the gas generator because of choked supply
tract. This resulted in incorrect operating conditions and decreased
parameters of the engine which was stopped by the emergency engine stop
command," Roskosmos said.
"The exposed production defect was accidental," it said adding the
reason may be qualified as an isolated case only after checking all
available engines.
