Synopsis
SA227 flight crew reported a fuselage cargo restraint point failed resulted in a cargo shift and a rejected takeoff.
Narrative
Just before XA00 local on Day 0; crew aborted a takeoff from ZZZ Airport due toexcessive noise from the back of the airplane. We contacted ZZZ Approach; cancelled our takeoffclearance and returned to the ramp. In the back of the airplane we found that part of our freight loadhad shifited rearward during acceleration and then returned to its original position during deceleration.The freight load was 3 skids total. The front skid was located in zone 2 and was secured with 2 strapsover the top and safety nets both front and rear. The skid and zone 2 were approximately the samelength and the skid did not move. The 2 remaining skids were located in zones 3 and 4. Zone 3 andzone 4 were both oversized compared to 1 skid alone so both skids were secured together in both zones3 and 4. They were secured with 2 straps over the top and an additional 3rd strap secured to the fuselagewalls wrapped around the rear of the skids applying forward force also with safety nets both front andrear. The remaining space after securing the 2 skids in zones 3 and 4 was about 3 feet.During acceleration for takeoff; it appeared that the attach point on the left fuselage wall failed andallowed the strap around the rear of the load to detach. This allowed the 2 skids to slide rearward untilthey contacted the strap attach points on the floor and the safety net 3 feet aft. During deceleration theskids moved to their original positions and stopped. The 2 attach points on the floor also released fromthe impact from the skids but the safety net held it's position and did not allow the load to move fartheraft.After securing the load using different methods; a different attach point on the left of the fuselage; and2 additional straps; the flight continued to destination without further incident.
