Not an NTSB Report, but some background info. I had heard the same story that it broke, but gave normal indications so they received no takeoff warning horn for trim. It was when it rotated prematurely that they knew that had a a big problem.
L-1011, San Diego, California
In April of 1977, a Lockheed L-1011 trijet, Delta flight 1080, had one of the horizontal stabilizers jam in the full trailing edge-up position prior to an instrument flight rules departure out of San Diego. This resulted in a large noseup pitching and rolling moment that almost exceeded the capability of the flight controls. The airplane was just about to stall in the clouds, when the Captain, using amazing insight, retarded the wing engine throttles and firewalled the center engine. This allowed him to regain enough control to maintain flight. The crew learned rapidly, continuing to use the throttles to supplement the remaining flight controls and moving passengers forward to reduce the pitchup tendency. They completed a safe landing. A less-capable crew would likely have been unable to save this airplane.
