 To the Director of Air Commerce.

On, at a point about of , an airplane of United States registry piloted by a licensed airman, while being operated in scheduled flight carrying mail, express, and one non-pay passenger, accidentally collided with the ground, with resultant  and the complete destruction of the aircraft and cargo.

The airplane, a Stinson, model SM–6000–B, bore Department of Commerce license number NO–10894 and was being operated between Chicago, Illinois and New Orleans, Louisiana, by the Chicago and Southern Air Lines, Incorporated. The pilot, John B. Lyrr, held a Department of Commerce transport pilot's license and a scheduled air transport rating. Both the pilot and the passenger, Paul Gardner, were killed.

This flight, originating in Chicago, was cleared for Springfield, Illinois, at 10:00 p.m. No unusual weather was predicted nor is there any evidence that any unusual weather was encountered.

The plane was next observed at a point about two miles from where the accident occurred. Witnesses reported seeing the airplane approach from a north-westerly direction and flying just above the tree tops. Straight ahead from this point were some gulleys about 50 feet deep and a heavily wooded area. It is believed that the pilot saw the terrain ahead because at this time he made a sharp turn to the right which took him away from the trees. From marks on the ground it appears that in this turn he allowed the right wing of the plane to contact the ground. The first mark clearly indicated a wing tip and the green navigation light was found imbedded in the ground at this point. After the first contact the plane evidently cartwheeled and came to rest with the fuselage upside down and with the tail pointing in a direction opposite to the approach.

For some unknown reason the pilot had not followed a direct course from Springfield toward St. Louis. A broken ground fog was reported over this area, but was not sufficient to constitute a hazard to the flight. There was nothing to suggest any reason for the low flying and whether or not the pilot had any intention of landing in the vicinity of the accident.

No flares were dropped and up until the time the ground was contacted, the engines sounded normal to those who heard the airplane.

It it the opinion of the Accident Board that the probable cause of this accident was an unintentional collision with the ground while flying at too low and altitude.
