	Installation of the main engine heat shields is underway.  Electrical 
connections between LMS and Columbia are continuing.  The tunnel adapter 
installation has been rescheduled for Tuesday. The Interface Verification Test 
(IVT) is scheduled for Monday and Tuesday next week. Orbiter avionics system

OPF Bay 1

	Removal of the three main engines is underway today.  Brake inspections 
are also being performed.  The functional test of the forward reaction control 
system was completed yesterday and payload bay deconfiguration will be 
completed today.  Rocketdyne engineers have successfully repeated the failure 
of a main engine igniter from the last launch.  It works at ambient temperatures 
but fails at 32 degrees Fahrenheit.  The igniter will be returned to the vendor.
