Yes that is correct. There was an in-depth article in NTSB reporter about it. The elevator controls were rigged incorrectly after a D6 maintance check resulting in a restricted movement. That and the CG was aft of acceptable limits. The pilots had computed the balance correctly but the FAA's average weight was and is considered to be off. It is too bad as the aircraft pitched up 54 degrees after t/o and the pilots were full forward on the controls with no effect. Must have been a scary situation. The NTSB mainly blamed the Air Midwest maintance program.
