The observations, test data, and conclusions obtained during the course of six full-scale fuselage burnthrough tests are presented. A comprehensive data base was developed which represented the flammability resistance of an intact fuselage when exposed to an exterior fuel fire. Three tests were conducted with the fuselage on the ground simulating a wheels-up condition, and three tests were conducted with the wheels down. Test results: (1) the aluminum skin provides protection from a fully developed fuel fire for 30 to 60 seconds; (2) the fiberglass acoustical insulation is an effective thermal barrier; (3) flame penetration into the cheek area provides a fire path into the cabin through the floor air return grills; (4) the aircraft with its gear extended is more vulnerable to burnthrough from a pool fire than an aircraft resting on its belly; and (5) areas, such as the empennage crawlthrough, that are not acoustically insulated are more vulnerable to burnthrough than other parts of the insulated fuselage.
