[net.columbia] Engine Problem May Be a Design Flaw

alb (02/28/83)

Engineers yesterday found the same problem that occurred in the
Number 2 engine of the Challenger in her Number 3 engine as well
and pulled both engines today.  NASA says the problem, a crack
in a hydrogen fuel line, appears to be a design flaw in the new
engines.  Columbia's engines didn't have the ''improvement'' and
thus didn't have the design.  No word was given on the effect
on STS-6's launch date.
