NTSB investigators have found that the right elevator was jammed on the chartered Ameristar Boeing MD-83 that ran off the runway on March 8 at Willow Run Airport in Ypsilanti, Michigan, with the Michigan men's basketball team, the Wolverines, on board. In an update released on Tuesday, the safety board said their post-accident examination revealed that movement of the control column in the cockpit appeared normal — the control columns were free to move, and the elevator control tabs moved as commanded. However, when investigators tried to move the elevator surfaces by hand, the left elevator moved normally, but the right elevator was jammed in a trailing‑edge-down position (airplane nose down). The airplane had flown to Willow Run two days before the accident, the NTSB said.
