On department out of sea a dozer blade which was strapped down (it was 8' long 18' wide X 1 1/4' thick) broke the tie down strap and slid off about 20' and hit some other cargo which was pushed up and damaged a psu (passenger service unit). We didn't know the blade broke loose, so on landing rollout the blade slid (being on rollers) foreward 30' going through the cargo net...damaging the interior of the L-1 door, the slide housing. After arriving at the gate the captain discovered the damage. Considerations: to make sure the cargo handlers have used enough and strong enough cargo straps to hold the cargo down. Callback conversation revealed the following: cargo loaders were depending on tie down straps and did not take into account the shape and weight of the cargo. Had the cargo not shifted side ways when it came forward on landing it would probably have entered the cockpit area with possible serious damage.

Title: IMPROPERLY SECURED CARGO BROKE LOOSE ON TKOF SHIFTED AFT CAUSING DAMAGE AND THEN SHIFTED FORWARD ON LNDG RESULTING IN ACFT DAMAGE.
Narrative: ON DEPT OUT OF SEA A DOZER BLADE WHICH WAS STRAPPED DOWN (IT WAS 8' LONG 18' WIDE X 1 1/4' THICK) BROKE THE TIE DOWN STRAP AND SLID OFF ABOUT 20' AND HIT SOME OTHER CARGO WHICH WAS PUSHED UP AND DAMAGED A PSU (PASSENGER SERVICE UNIT). WE DIDN'T KNOW THE BLADE BROKE LOOSE, SO ON LANDING ROLLOUT THE BLADE SLID (BEING ON ROLLERS) FOREWARD 30' GOING THROUGH THE CARGO NET...DAMAGING THE INTERIOR OF THE L-1 DOOR, THE SLIDE HOUSING. AFTER ARRIVING AT THE GATE THE CAPT DISCOVERED THE DAMAGE. CONSIDERATIONS: TO MAKE SURE THE CARGO HANDLERS HAVE USED ENOUGH AND STRONG ENOUGH CARGO STRAPS TO HOLD THE CARGO DOWN. CALLBACK CONVERSATION REVEALED THE FOLLOWING: CARGO LOADERS WERE DEPENDING ON TIE DOWN STRAPS AND DID NOT TAKE INTO ACCOUNT THE SHAPE AND WEIGHT OF THE CARGO. HAD THE CARGO NOT SHIFTED SIDE WAYS WHEN IT CAME FORWARD ON LNDG IT WOULD PROBABLY HAVE ENTERED THE COCKPIT AREA WITH POSSIBLE SERIOUS DAMAGE.
