C-130 Weldbonded Fuselage Panel Flight Evaluation Program.
Abstract
The objective of this program was to conduct an in-service evaluation of the C-130 weldbonded fuselage panel. A total of seven nondestructive inspections were conducted during which all of the inspections included visual and ultrasonic inspection of the weldbonded joints. Three of the seven inspections included radiographic inspections of a portion of the spot-welds in the weldbonded fuselage panel. All inspections were conducted coincident with aircraft isochronal inspections. The fuselage panel performed in an operational environment with a minimum of problems as the only defects detected were some small breaks in the interior paint finish over the skin-to-ring frame sealed fillets. These small breaks were detected with the aid of a pocket magnifier as they could not have been detected by the naked eye. These small paint finish breaks were repaired and recurrence or additional breaks were not detected in the two subsequent inspections. The Air Force will continue conducting periodic inspections on the weldbonded fuselage panel.
