Synopsis

HOT START.

Narrative

DURING ENG START; CAPT TOLD ME TO START THE REMAINING ENG. OUR PROC IS TO CLOSE THE ISOLATION VALVE AND TURN ON THE R PACK AFTER THE START VALVE CLOSES AND THE RED OVERHEAT LIMIT LINE DISAPPEARS FROM THE EGT GAUGE ON THE CRT. I WAS SURPRISED TO SEE THAT THE STARTER WAS STILL ON. AFTER A FEW SECONDS; THE R START SWITCH MOVED TO AUTO AND A FEW SECONDS LATER; THE VALVE LIGHT EXTINGUISHED INDICATING THE VALVE WAS CLOSED. THE SLOW MOVING START VALVE BROKE MY ROUTINE AND I TURNED ON THE RIGHT PACK WITHOUT REFERENCING THE R EGT LIMIT LINE. I THEN BEGAN THE START SEQUENCE ON THE L ENG. AFTER THAT ENG STARTED; I BEGAN THE FLOW PATTERN FOR AFTER ENG START. AT THIS TIME THE CAPT NOTICED THE R ENG EGT WAS IN THE RED. HE SHUT DOWN THE ENG. WE MOTORED THE ENG TO COOL IT. THE LIMIT WAS EXCEEDED BY 11 DEGS TO 496 DEGS. IT WAS RED FOR JUST A FEW SECONDS. WE INFORMED THE MECH OF THE OVERHEAT AND OUR INTENTION TO RESTART THE ENG. HE CONCURRED. THE ENG WAS RESTARTED AND OPERATED NORMALLY TO DEST. AT DEST; IT WAS DETERMINED BY MAINT THAT THE ENG REQUIRED A VISUAL INSPECTION. IT WAS HOT; THE AIRPLANE WAS FULL; AND WE WANTED OUR PAX TO MAKE THEIR CONNECTIONS. I SHOULD HAVE SUGGESTED WE CONSIDER RETURNING TO THE GATE TO DISCUSS THE SIT IN FURTHER DETAIL WITH MAINT PRIOR TO DEPARTING THE FIELD.
