xxxx said they had a hydraulic problem (transfer I think). The crew brought it back to SFO. That night maintenance crews pinned the landing gear in place so they could raise the gear handle to troubleshoot the problem. The REAL problem is that whoever pinned the body gear (which is AFT of the wing gear) did it incorrectly. Basically the body gear wasn't pinned at all. When the gear handle was placed in the up position With 110,000# of fuel in the wing tanks and only the body gear retracted, the plane's CG went aft of the wing gear and down it went, settling now on the wing gear and the tail.
