Narrative

THE FOLLOWING NARRATIVE IS TO THE BEST OF MY RECOLLECTION OF THE EVENTS THAT OCCURRED ON MAR/XX/97; FLT FROM GUM TO HKG. WE BEGAN OUR DAY OUT OF GUAM NORMALLY; ALL CHKS AS WELL AS CHKLISTS WERE COMPLETED. AS WE TAXIED OUT IT WAS DETERMINED THAT IT WOULD BE MY LEG TO HONG KONG. AS WE REACHED THE END OF THE RWY WE WERE CLRED FOR TKOF. UPON ROTATION THE #1 AC AND DC BUSSES BECAME UNPOWERED (#1 GENERATOR PLACARDED INOP AND #1 ISOL RELAY OPENED). THIS CAUSED THE CAPT'S INSTS AMONG OTHERS TO BE DEPOWERED; I CONTINUED WITH THE DEP AND CLBOUT AS THE CAPT AND SO ADDRESSED THE PROB. THEY WERE ABLE TO REPOWER THE BUSSES AND WE DECIDED THAT WE WOULD PRESS ON. APPROX 1 HR OUT OF HONG KONG IN LEVEL FLT THE SAME PROB OCCURRED AND WAS AGAIN ADDRESSED BY THE CAPT AND SO. SHORTLY AFTER WE BEGAN OUR DSCNT FOR HKG; WE WERE INFORMED THAT THE IGS RWY 13 WAS IN USE AND WERE GIVEN VECTORS FOR THE INTERCEPT. WE TUNED THE IGS RWY 13 AND RECEIVED A PROPER IDENT; BUT WE HAD ABNORMAL INST INDICATIONS (FLAGS). ATC GAVE US THE FINAL HEADING TO INTERCEPT AND CLRED US FOR THE IGS RWY 13 APCH. I FELT VERY UNCOMFORTABLE WITH THESE INDICATIONS AND ASKED THE CAPT TO VERIFY WITH ATC THAT THE IGS WAS UP WHICH HE DID. ATC CONFIRMED THAT THE IGS WAS FUNCTIONING PROPERLY AND STATED THAT OTHER ACFT WERE RECEIVING THE SIGNAL. SHORTLY AFTER; ATC NOTIFIED US THAT WE WERE PASSING THROUGH THE LOC. THE LOC NEEDLE NEVER LEFT THE CAGED POS. AT THAT POINT WE ABANDONED THE APCH AND REQUESTED VECTORS TO THE VOR-DME RWY 13 AS IT APPEARED WE WOULD BE UNABLE TO FLY THE IGS RWY 13 APCH DUE TO EQUIP FAILURE. ATC VECTORED US INTO POS TO COMMENCE THE 2ND APCH TO RWY 13. THE ATIS CALLED THE WX FEW 13 SCATTERED 17; 6 KM WITH DRIZZLE; WIND: 100 DEGS/15 KTS. WITH THIS IN MIND WE FELT THAT THIS APCH COULD BE ACCOMPLISHED WITHOUT A PROB. WE FLEW THE PUBLISHED APCH AND UPON REACHING THE MDA HAD GND CONTACT. AS WE APCHED THE MISSED APCH WE LOST GND CONTACT AND AT THE MAP I EXECUTED THE PUBLISHED MISSED APCH; THE CAPT ADVISED ATC OF THE MISSED APCH AND STATED OUR INTENTION TO DIVERT TO MNL. AT THIS POINT I ASKED THE SO WHAT OUR FUEL WAS; HE STATED THAT IT WAS APPROX 24000 LBS. I THEN ASKED HOW MUCH WE NEEDED TO GET TO MNL THE CAPT SAID 22800 LBS. AT THAT POINT IT WAS OBVIOUS THAT WE COULD NOT MAKE IT TO MNL. I SUGGESTED THAT WE REQUEST THE PAR TO RWY 31 BECAUSE THE IGS AND VOR APCHS WERE NOW NOT AN OPTION. WE ALL AGREED AND THE PAR RWY 31 HKG WAS REQUESTED. AT THIS POINT I BELIEVE THE CAPT EXCUSED HIMSELF FROM THE FLT DECK. ATC GAVE US SEVERAL VECTORS AND THEN ISSUED US A HOLDING CLRNC IN WHICH I ACKNOWLEDGED AND COMPLIED WITH. AS I ENTERED THE HOLD ATC ADVISED US THAT IT WOULD BE APPROX 45 MINS IN THE HOLD BEFORE THEY COULD ACCOMMODATE US. AT ABOUT THIS TIME I NOTICED THAT CAPT B (A DEADHEADING PLT) WAS STANDING BEHIND THE CAPT'S SEAT. I ASKED HIM IF HE WANTED TO JOIN ME AND HE DID. CAPT B INFORMED ATC THAT THE HOLDING REQUIREMENT WOULD PLACE US IN A SHORT FUEL SIT. THEY ASKED US IF WE WANTED TO DECLARE AN EMER. WE STATED THAT WE COULD NOT HOLD FOR THAT LONG SO IF THAT REQUIRED US TO DECLARE AN EMER SO WE COULD START THE APCH SOONER THEN WE WOULD DO THAT; THEY SAID THAT IS THE CASE SO WE DECLARED AN EMER. FOLLOWING OUR DECLARATION OF THE EMER; WE WERE VECTORED TO THE PAR RWY 31 AND LANDED WITH NO FURTHER COMPLICATIONS. WE LANDED WITH 17400 LBS OF FUEL ON BOARD. IN CONCLUSION REGARDING THE CASE OF CAPT A LEAVING THE COCKPIT; I BELIEVE IT WAS A WISE AND COURAGEOUS EFFORT ON HIS PART TO INSURE THE SAFETY OF THE ACFT BY UTILIZING ALL HIS RESOURCES. HE OBVIOUSLY REALIZED AT SOME POINT THAT HE COULD NOT CONTINUE SO HE CALLED UPON HIS RESOURCES; CAPT B TO REPLACE HIM. I RESPECT THE DECISION THAT CAPT A MADE GIVEN THESE DIFFICULT CIRCUMSTANCES. SUPPLEMENTAL INFO FROM ACN 364644: FARS SHOULD NOT ALLOW PRIMARY ELECTRICAL SYS TO BE MEL'ED AFTER TERMINATION OF A FLT IN A PRIMARY AIRLINE HUB. FLT TIME LIMITATIONS SHOULD BE REDUCED. CAPT HAD FLOWN OVER 100 HRS FOR THE MONTH BECAUSE OF A LACK OF STAFFING BY AIRLINE IN HUB. ATC FACILITIES SHOULD NEVER FORCE A CREW INTO DECLARING AN EMER FOR PRIORITY SEQUENCING. ATC SPENT MORE TIME HARASSING US INTO DECLARING AN EMER THAN IT WOULD HAVE TAKEN TO JUST SEQUENCE US. AN EMER WAS DECLARED TO GET ATC TO SIMPLY COOPERATE WITH US. FAA SHOULD MANDATE THAT NO MGMNT PERSONNEL MAY QUESTION A CAPT'S DECISION TO DISCONTINUE A FLT FOR SAFETY REASONS. I DID NOT OBJECT TO THE CAPT'S DECISION TO INVOLVE THE DEADHEAD CREW IN THE FINAL PHASES OF OUR FLT. SPECIFICALLY; I THINK THE CAPT MADE AN EXCELLENT DECISION (AS ANY GOOD CAPT WOULD DO) TO UTILIZE ALL THE RESOURCES AVAILABLE TO HIM TO INSURE A POSITIVE OUTCOME TO THE SIT. HIS DECISION TO UTILIZE THE OTHER CREW WAS A SELFLESS CRM DECISION THAT PROVIDED EXCELLENT BACK UP TO THE FLYING CREW AND ENHANCED THE SAFETY OF THE ACFT BY PROVIDING EXTRA EYES AND SUPPORT IN A HIGH STRESS SIT. SUPPLEMENTAL INFO FROM ACN 365099: EXAMINING THE FUEL STATUS; IT WAS CLR THAT WE HAD CONSUMED OUR RESERVE FUEL DURING THE LOW ALT MANEUVERING AND HAD TO LAND IN HONG KONG. GIVEN ALL FACTORS; INCLUDING THE WX; WE ELECTED TO REQUEST A PAR APCH TO RWY 31. ATC ADVISED US THAT A 45 MIN HOLDING WOULD BE REQUIRED UNLESS WE DECLARED AN EMER. DURING THE MISSED APCH FROM THE VOR/DME; I BEGAN TO FEEL STRESSED AND TIRED FROM THE ACCUMULATED EFFECT OF THE PREVIOUS MONTH'S FLT TIME (APPROX 100 HRS DUE TO SHORT-STAFFING OF THE DC10 BASE); I WAS CONCERNED THAT OUR SIT COULD DETERIORATE FURTHER. TO MAXIMIZE SAFETY; I REQUESTED A DEADHEADING DC10 CAPT; TO ASSUME COMMAND OF THE ACFT; KNOWING HIS EXPERIENCE INTO HONG KONG WAS VASTLY GREATER THAN MINE. CONSIDERING ALL FACTORS; INCLUDING THE LIMITED APCH CAPABILITY; FUEL STATUS AND WX; WE DECLARED AN EMER; TO BE GIVEN THE PAR APCH TO RWY 31; LNDG WITH NO FURTHER COMPLICATIONS. BLOCK-IN FUEL WAS 17400 LBS. ON THE GND; THE ELECTRICAL SYS WAS QUICKLY FIXED; HOWEVER; THE RADIO PROB INDICATED THAT: 1) THE #2 ILS RECEIVER HAD FAILED. 2) THE SINGLE TUNING HEAD FOR BOTH ILS RECEIVERS HAD MALFUNCTIONED.
