Narrative:
During takeoff roll felt bump in rear of aircraft. Knowing we were carrying the new ballast containers that my company has (which have lots of play, some movement), I thought it was the play with the containers hitting the locks. During the takeoff the nosewheel came off the ground by itself at approximately V1. I held forward pressure on the yoke and climbed out at 15 degrees nose up, rather than our standard 18 degrees. The aircraft pressurized, and we did have a loadmaster on board so I sent him to the back to see if the containers did move. They indeed did move to the aft bulkhead. He moved the containers back in place and locked them in place using portable locks. Once we arrived at our destination (iln), mechanic met the aircraft. Damage to aircraft. #2 engine support bulkhead torn loose at bottom, where it meets the floor, beams and flooring and it also buckled the outer skin of aircraft below the #2 engine pylon. Container came within inches of pressure vessel also control cables in tailcone of the aircraft. Type aircraft, DC9.

Title: CARGO CONTAINER IN AN MLG CARGO ACFT SHIFTED DURING TKOF CAUSING AN AFT CTR OF GRAVITY AND DAMAGE TO THE FUSELAGE ENG MOUNT BULKHEAD.
Narrative: DURING TKOF ROLL FELT BUMP IN REAR OF ACFT. KNOWING WE WERE CARRYING THE NEW BALLAST CONTAINERS THAT MY COMPANY HAS (WHICH HAVE LOTS OF PLAY, SOME MOVEMENT), I THOUGHT IT WAS THE PLAY WITH THE CONTAINERS HITTING THE LOCKS. DURING THE TKOF THE NOSEWHEEL CAME OFF THE GND BY ITSELF AT APPROX V1. I HELD FORWARD PRESSURE ON THE YOKE AND CLBED OUT AT 15 DEGS NOSE UP, RATHER THAN OUR STANDARD 18 DEGS. THE ACFT PRESSURIZED, AND WE DID HAVE A LOADMASTER ON BOARD SO I SENT HIM TO THE BACK TO SEE IF THE CONTAINERS DID MOVE. THEY INDEED DID MOVE TO THE AFT BULKHEAD. HE MOVED THE CONTAINERS BACK IN PLACE AND LOCKED THEM IN PLACE USING PORTABLE LOCKS. ONCE WE ARRIVED AT OUR DEST (ILN), MECH MET THE ACFT. DAMAGE TO ACFT. #2 ENG SUPPORT BULKHEAD TORN LOOSE AT BOTTOM, WHERE IT MEETS THE FLOOR, BEAMS AND FLOORING AND IT ALSO BUCKLED THE OUTER SKIN OF ACFT BELOW THE #2 ENG PYLON. CONTAINER CAME WITHIN INCHES OF PRESSURE VESSEL ALSO CTL CABLES IN TAILCONE OF THE ACFT. TYPE ACFT, DC9.
