ENG POD SCRAPE; APPARENTLY ON LNDG.

Narrative

FLT WAS SCHEDULED TO DEPART SEA-TAC ARPT FOR TOKYO WITH INTERVENING STOP IN ANC. FLT LEFT SEA AT XA45 HRS AFTER A 17-HR DELAY. CREW WAS FATIGUED. FLT PROCEEDED NORMALLY TO VICINITY OF ANC; BUT WX WAS BELOW MINIMUMS. AN APCH WAS BEGUN TO ELMENDORF AFB AND; PRIOR TO GLIDE PATH INTERCEPT; THE VISIBILITY AT ANC ROSE TO 6000 FT RVR. APCH CTL GAVE US VECTORS TO A L BASE FOR THE ANC ILS RWY 6R APCH. THERE WAS A FOG BANK OVER THE APCH END OF THE RWY AND THE APCH LIGHTS COULD BE SEEN REFLECTING OFF THE WATER UNDERNEATH THE SHALLOW CEILING. I FEEL THAT THIS CREATED A MINDSET IN THE CREW THAT THE APCH WOULD BE RELATIVELY EASY. THE COPLT ELECTED TO HAND FLY WITH THE AID OF THE FLT DIRECTOR. WE SAW THE APCH LIGHTS AT 400 FT WITH THE RWY ACTUALLY OBSCURED IN FOG. I EXPECTED BETTER VISUAL REFS. THE APCH BECAME UNSTABLE AS THE COPLT BEGAN MANEUVERING WITH RESPECT TO VISUAL REFS A LITTLE TOO EARLY. WE GOT ABOUT 1/2 DOT LOW ON GLIDE PATH AND; IN CORRECTING OUR VERT POS; GOT OFFSET R OF CTRLINE. TOUCHDOWN OCCURRED WHILE STILL CORRECTING L FOR THE OFFSET. THE TOUCHDOWN ALT WAS PLUS 1.5 DEGS PITCH AND 11.0 DEGS L BANK. THIS CAUSED THE #1 ENG (L OUTBOARD) TO SCRAPE THE RWY SURFACE. DUE TO DARKNESS AND THE NATURE OF THE DAMAGE; IT WAS NOT DISCOVERED DURING PREFLT AT ANC. FLT PROCEEDED NORMALLY TO TOKYO WHERE THE DAMAGE WAS DISCOVERED. ALTHOUGH ENG OP WAS NORMAL; THE DAMAGE WAS SUFFICIENT TO REQUIRE AN ENG CHANGE. IN RETROSPECT WE SHOULD HAVE: 1) REALIZED HOW DIFFICULT AN APCH INTO A LCL FOG CONDITION CAN BE; AND CREATE A MINDSET TO EXPECT THE WORST AT THE FINAL STAGES OF THE APCH. 2) USED A COUPLED APCH AT A MINIMUM; AND MAYBE AUTOLAND; TO COMPENSATE FOR FATIGUE AND ANY UNEXPECTED CONDITIONS AFTER RWY ENVIRONMENT IN SIGHT. 3) GONE AROUND WHEN THE APCH BECAME UNSTABLE. SUPPLEMENTAL INFORMATION FROM ACN 287458: TKOF FROM SEA WAS NORMAL. LNDG IN ANC WAS FIRM BUT NOT HARD. TKOF FROM ANC NORMAL. LNDG IN NRT NORMAL. TKOF TAXIING WASN'T DONE IN ANY AREA THAT MIGHT HAVE CAUSED A POD STRIKE. ALL WE CAN FIGURE IS THAT SO DID NOT CATCH IT ON HIS PREFLT IN SEA. IT WAS XA45 AM AND POURING RAIN. SUPPLEMENTAL INFORMATION FROM ACN 287600: ORIGINALLY SCHEDULED TO DEPART SEA XF00L OCT/XX/94. CREEPING DELAY AND DEPARTED XA45 AM LCL OCT/XY/94.
