Narrative:

While on climb out from fll, a drop in engine #1 EPR was noticed, throttle was adjusted to attain climb thrust, all other engine indications were normal. Later, engine #1 EPR indication dropped again at about FL250. Maintenance was notified and advised us to divert to mia for maintenance. Flight headed for mia, shortly after, cabin altitude started climbing and so switched bleed to #2 also. Generator relay #1 tripped. Decision to shut down engine #1 was made and done according to air carrier X SOP, dumped fuel (nozzle valved indicator stuck in disagreement), declared emergency and an uneventful landing was made at mia. All flight crew members including flight attendants were in the loop and decision making process.

Title: A B727-200 IN CLB AT FL250 DECLARED AN EMER AND DIVERTED DUE TO ENG PRESSURE RATIO DROP.

Narrative: WHILE ON CLBOUT FROM FLL, A DROP IN ENG #1 EPR WAS NOTICED, THROTTLE WAS ADJUSTED TO ATTAIN CLB THRUST, ALL OTHER ENG INDICATIONS WERE NORMAL. LATER, ENG #1 EPR INDICATION DROPPED AGAIN AT ABOUT FL250. MAINT WAS NOTIFIED AND ADVISED US TO DIVERT TO MIA FOR MAINT. FLT HEADED FOR MIA, SHORTLY AFTER, CABIN ALT STARTED CLBING AND SO SWITCHED BLEED TO #2 ALSO. GENERATOR RELAY #1 TRIPPED. DECISION TO SHUT DOWN ENG #1 WAS MADE AND DONE ACCORDING TO ACR X SOP, DUMPED FUEL (NOZZLE VALVED INDICATOR STUCK IN DISAGREEMENT), DECLARED EMER AND AN UNEVENTFUL LNDG WAS MADE AT MIA.
