Narrative:

We were at the end of our flight from osaka, kansai (rjbb) to anchorage. The first officer was hand flying the approach. The WX was VMC. We were cleared for a visual approach and cleared to land behind a 747 on runway 6R. The aircraft was flown with reference to the localizer and GS and it was a very stable approach down to about 30 ft. At that time, it appeared to me that the aircraft was sinking too rapidly. I applied back elevator in an attempt to stop the sink rate, it didn't seem to have any effect as the aircraft landed very hard and pitched up. At the same time forward pressure was applied to the elevator and I heard a loud bang. The aircraft then settled back down and the nose up attitude started to decrease. The rest of the rollout was normal. Post flight inspection revealed some damage to the aft lower fuselage. Possible cause or contributing factors: slightly late or slow flare. We may have encountered some wind shear or turbulence from the 747 that landed before we did. This airplane type (md-11) seems to be acquiring quite a lot of history throughout the industry for this type of occurrence.

Title: AN ACR MD-11 HAD A TAIL STRIKE.

Narrative: WE WERE AT THE END OF OUR FLT FROM OSAKA, KANSAI (RJBB) TO ANCHORAGE. THE FO WAS HAND FLYING THE APCH. THE WX WAS VMC. WE WERE CLRED FOR A VISUAL APCH AND CLRED TO LAND BEHIND A 747 ON RWY 6R. THE ACFT WAS FLOWN WITH REF TO THE LOC AND GS AND IT WAS A VERY STABLE APCH DOWN TO ABOUT 30 FT. AT THAT TIME, IT APPEARED TO ME THAT THE ACFT WAS SINKING TOO RAPIDLY. I APPLIED BACK ELEVATOR IN AN ATTEMPT TO STOP THE SINK RATE, IT DIDN'T SEEM TO HAVE ANY EFFECT AS THE ACFT LANDED VERY HARD AND PITCHED UP. AT THE SAME TIME FORWARD PRESSURE WAS APPLIED TO THE ELEVATOR AND I HEARD A LOUD BANG. THE ACFT THEN SETTLED BACK DOWN AND THE NOSE UP ATTITUDE STARTED TO DECREASE. THE REST OF THE ROLLOUT WAS NORMAL. POST FLT INSPECTION REVEALED SOME DAMAGE TO THE AFT LOWER FUSELAGE. POSSIBLE CAUSE OR CONTRIBUTING FACTORS: SLIGHTLY LATE OR SLOW FLARE. WE MAY HAVE ENCOUNTERED SOME WIND SHEAR OR TURB FROM THE 747 THAT LANDED BEFORE WE DID. THIS AIRPLANE TYPE (MD-11) SEEMS TO BE ACQUIRING QUITE A LOT OF HISTORY THROUGHOUT THE INDUSTRY FOR THIS TYPE OF OCCURRENCE.
