MD11 INTL CREW DIVERTS TO PDX DUE TO INADEQUATE REST.

Narrative

THE NIGHT BEFORE THE SUBJECT FLT; I WENT TO BED ABOUT YA00. I GOT UP JUST AFTER YB00 AND WAS OUT THE DOOR AND ON THE ROAD TO THE ARPT BY XA00. I CAUGHT THE BUS FROM THE PARKING LOT AT APPROX XB30 AND WAS IN THE BRIEFING ROOM AT SC50. SIGN-IN FOR THIS TRIP WAS XD00; BUT TFC UNCERTAINTIES IN THE ATLANTA AREA REQUIRE ME TO PLAN FOR INCREASED TRAVEL TIME. THE PREDEP BRIEFING WAS HAMPERED BY THE LACK OF A PLOTTING CHART FOR THE EXTREMELY NORTHERN RTE OVER WHICH WE HAD BEEN DISPATCHED. FOLLOWING COORD WITH THE CHIEF PLT; ADEQUATE SUBSTITUTIONS WERE ARRANGED. LIKEWISE; THE PUSHBACK AND TAXI PHASES WERE COMPLICATED BY #2 FADEC; CARGO DOOR TEST AND AUTOBRAKE FAILURES; ALL OF WHICH WERE ULTIMATELY RESOLVED. DEP AND CLBOUT FROM ATL WERE NORMAL. SHORTLY AFTER TOP OF CLB; THE RELIEF CREW CONSTRUCTED THE RELIEF FACILITY AND BEGAN THEIR 3 HR BREAK. WHEN THEY RETURNED TO ASSUME THEIR FLYING DUTIES; THE FLT WAS AT A POINT W OF CHURCHILL; MANITOBA; ALONG HUDSON BAY. I INQUIRED AS TO THE AMOUNT OF REST THAT THEY HAD BEEN ABLE TO GET. THEY INFORMED ME THAT THEY HAD NOT SLEPT. WEIGHING THIS; AND MY OWN PRIOR INABILITY TO ACHIEVE PROPER REST IN THIS PARTICULAR TYPE OF REST FACILITY; I DECIDED THAT THIS CREW WOULD BE DANGEROUSLY FATIGUED WHEN IT CAME TIME TO APCH A HIGH DENSITY ARPT AT THE END OF ANOTHER TEN OR MORE HRS IN THE AIR. I DISCUSSED MY CONCERN WITH THE OTHER 3 PLTS; AND I DECIDED AT THAT POINT THAT IT WAS IN EVERYONE'S BEST INTERESTS TO DIVERT AND GET A FRESH CREW. PDX WAS THE LOGICAL DIVERT LOCATION DUE TO THE AVAILABILITY OF MD11 RESERVE CREWS; AND I DECIDED TO DIVERT THERE. FOLLOWING SOME INITIAL COMS DIFFICULTIES WITH FLT CTL; THE DIVERT WAS COORDINATED. THE REMAINDER OF THE FLT TO PDX WAS NORMAL. OUR PAX WERE ACCOMMODATED ON ANOTHER FLT FROM PDX TO NRT. I BELIEVE ALL THE DECISIONS I MADE ON THIS TRIP WERE OPERATIONALLY SOUND; PRUDENT AND SAFE; AND IN THE BEST INTERESTS OF THE PAX; THE CREW AND THE COMPANY.
