A Continental Airlines McDonnell Douglas DC-10, N68041, on a crew training flight, departed from Tucson International Airport, Arizona at 11:52 local time. There were nine persons on board the flight.
Approximately 1 hour after departure, the No. 2 engine low-pressure turbine assembly, turbine rear frame, and reverser assembly separated
from the aircraft. The crew conducted a standard in-flight engine shutdown procedure and landed the aircraft at Tucson International Airport
without further incident at 13:06.

The National Transportation Safety Board determines that the probable cause of this incident was the failure of a stiffener ring on the pressure
tube located within the high-pressure turbine shaft of No. 2 engine. This failure resulted in a condition of rotor imbalance which precipitated a
sequence of component failures culminating in separation of the aft portion of the engine.
