The litigation arose from the July 13, 1982 crash of a Navy T-34C Turbo-Mentor aircraft at Middleton Field, Alabama, during touch-and-go exercises. Lieutenant Commander Barbara Ann Rainey, a flight instructor, and her student Ensign Donald Bruce Knowlton were killed when the plane banked sharply right after a premature left turn, lost altitude, and crashed.
The surviving spouses of the pilots filed a product liability action against Beech Aircraft Corporation, the manufacturer, and Beech Aerospace Services, Inc., which serviced the plane, alleging that a defect in the fuel control system caused an engine rollback and loss of power. Because the aircraft was destroyed and there were no survivors, the cause of the accident could not be determined from the available evidence. The defense presented an investigative JAG Report prepared by Lieutenant Commander William Morgan pursuant to Navy authority.
The report contained sections on findings of fact, opinions, and recommendations, including statements that the engine was operating at reduced power at impact and that the most probable cause was the pilots' failure to maintain proper interval, while noting the possibility of rollback. Five or six months after the accident, plaintiff John Rainey, the deceased pilot's husband and a Navy flight instructor, sent a letter to Morgan outlining his own investigation and concluding that the most probable cause was a loss of useful power due to a pneumatic sensing or fuel flow malfunction.
At trial, the defense called Rainey as an adverse witness and questioned him about portions of the letter concerning his wife's attempt to cancel the flight and a hard right turn by the aircrew. On cross-examination, the court sustained an objection to a question asking whether Rainey had stated in the letter that rollback was the most probable primary cause. After a two-week trial, the jury returned a verdict for the defendants. A panel of the Eleventh Circuit reversed, and on rehearing en banc the court divided evenly on one issue while unanimously holding that the district court erred in restricting cross-examination. The Supreme Court granted certiorari.
