Summary:

Full-scale light-airplane crashes simulating stall-spin accidents were conducted to determine the decelerations to which occupants are exposed and the resulting harness forces encountered in this type of accident. Crashes at impact speeds from 42 to 60 miles per hour were studied. The airplanes used were of the familiar steel-tube, fabric-covered, tandem, two-seat type.

In crashes up to an impact speed of 60 miles per hour, crumpling the forward fuselage structure prevented the maximum deceleration at the rear-seat location from exceeding 26 to 33 g. This maximum g value appeared independent of the impact speed. Restraining forces in the seat-belt - shoulder harness combination reached 5800 pounds. The rear-seat occupant can survive crashes of this type studied at impact speeds up to 60 miles per hour, if body movement is restrained by an adequate seat-belt -shoulder-harness combination so as to prevent injurious contact with obstacles normally present in the cabin. Inwardly collapsing cabin structure, is a potential hazard in the higher-speed crashes.
