At 18:25 central time, a Beech BE-76 crashed near the Richard Lloyd Jones Airport, killing the pilot and flight instructor. The pilot radioed Tulsa Approach and said the flight was four miles north of the Okmulgee Airport and they had an engine on fire. The pilot requested a straight in landing on runway 1L at Richard Lloyd Jones Airport. Tower controllers saw the airplane approaching fast and saw smoke coming from the right engine. The pilot then said he did not have a green light and that he was going around to land on 19R. The airplane began a turn, then rolled to the right and crashed. Examination of the right engine compartment revealed an oil line had separated from a fitting.
