ATTEMPTING TO MAKE A VISUAL APCH AT MINIMUMS RESULT IN CLOSE PROX TO MOUNTAINOUS TERRAIN AND THE RESULTING MISS CAUSED THE ENGINES TO BE OVERTEMPED.

Narrative

WE WERE CLRED FOR AN ILS APCH. DURING THE APCH THE GLIDE SLOPE WAS SEPARATING AND THE LOC WAS UNSTEADY. A MISSED APCH WAS MADE DUE TO A LAYER OF CLOUDS OBSERVING THE RWY. I READ THE MISSED APCH PROCEDURE TO CAPT; AND HE ELECTED TO ENTER THE OUTBOUND RADIAL DOWNWIND FROM CONDOR CORCHA RATHER THAN FLYING OVER THE TOP OF CONDOR CORCHA SINCE WE WERE VFR AND HAD CLIMBED TO THE PROPER DOWNWIND ALT. DURING THE SECOND ATTEMPT ILS APCH ONCE AGAIN THE GLIDE SLOPE WAS INOPERATIVE AND LOC SIGNAL UNSTEADY. IT IS POSSIBLE THE ACFT MAY HAVE VEERED SLIGHTLY RIGHT OR LEFT OF THE LOC DURING THE APCH WHICH WAS CONTINUED AS A GLIDE SLOPE OUT APCH. ONCE AGAIN A MISSED APCH WAS MADE FOLLOWING THE NORMAL MISSED APCH PROCEDURE. DURING THE CLIMB OUT THE SECOND OFFICER CALLED OUT 'OVER TEMP ON #1' WHEREBY THE CAPT IMMEDIATELY RETARDED THE THROTTLES. IT IS POSSIBLE THAT THERE WAS A MOMENTARY OVERTEMP ON #1 ENGINE BUT NO RED OVERTEMP LIGHTS WERE ON AT ENGINE SHUTDOWN ON THE RAMP. THE THIRD APCH WAS SUCCESSFUL SINCE THE WEATHER OBSCURING THE RWY HAD MOVED TO ONE SIDE. A NORMAL LANDING WAS MADE. THE TWR NEEDS TO ADVISE OF ILS CONDITION PRIOR TO ACFT COMMENCING APCH. SUPPLEMENTAL INFORMATION FROM ACN 83082: I EXECUTED MISSED APCH BUT WAS IN THE CLEAR OVER RWY ON GO-AROUND. REQUESTED AND WAS APPROVED FOR RIGHT DOWNWIND AND VISUAL LANDING. ABEAM RWY END; WEATHER OFF END OF RWY WOULD NOT ALLOW VISUAL SO I REQUESTED SECOND IFR APCH. INFORMED TWR GLIDE SLOPE APPEARED TO BE INOPERATIVE BUT WAS INFORMED IT WAS OPERATING NORMALLY. OVERTEMP LIGHTS WERE NOT; TO MY KNOWLEDGE; ON AT ARRIVAL AT GATE NOR WAS IT SUGGESTED THAT A LOGBOOK ENTRY BE MADE. SUPPLEMENTAL INFORMATION FROM ACN 82994: MISSED APCH PROCEDURES WERE NOT FOLLOWED AND A NEAR COLLISION WITH TERRAIN WAS NARROWLY OVERTED BY SECOND OFFICER CALLING FOR GO AROUND AND ADDING POWER. DURING CLIMB OUT; ENGINES WERE OVERTEMPED. CALLBACK CONVERSATION WITH THE REPORTER HAS REVEALED THE FOLLOWING INFORMATION: COMPANY IS USING A COMMERCIAL CHART DEPICTING AN ILS PROC. IS SENDING A COPY OF THE PROC USED FOR THIS ARPT. PRIOR TO THE MERGER WITH ANOTHER COMPANY; IT WAS ACR POLICY TO REQUIRE A NEW CAPT TO OBSERVE THE OPERATION AT THIS HIGH ALT ARPT BEFORE BEING CERTIFIED TO FLY ACFT WITH PAX IN AND OUT. THIS POLICY HAS BEEN DROPPED AS TOO EXPENSIVE BY THE NEW COMPANY. SEVERAL DAYS LATER THE F/O WAS GETTING A CHECK RIDE AND MADE THE COMMENT TO THE CHECK PLT THAT THEY HAD AN INTERESTING APCH INTO QUITO. RESULT OF THE DISCUSSION THE ENTIRE CREW WAS PULLED OUT OF SCHEDULE WITH PAY AND DISCUSSED THE INCIDENT. DISCIPLINARY ACTION WAS TAKEN IN THE FORM OF CRM TRAINERS AND SIMULATOR TIME MAKING AN APCH TO QUITO. INSISTS ENGINE WAS NOT OVERTEMPED. AFTER HOLDING REPORT FOR SEVERAL WEEKS AND STILL NO APCH PLATE ELECTED TO PROCESS AND GET IN DATA BASE.
