description abstract	Description of Driving Event: The payload bay duct heater adds measured quantities of heat independently to each duct system. This raises the temperature of the process air from the cooling coils to the desired interface temperature leaving the portable purge unit and engine control system room. With no overtemp switches installed, excessive heat from the payload bay duct heaters burned through the duct insulation, causing severe damage with a potential for orbiter damage.
