A lightweight, add-on structure which smoothly cuts general aviation airframes along an egress area periphery, jettisoning the severed portion for rapid pilot egress is described. Flexible charges held against the airframe's interior cut the airframe while reaction surfaces, attached to the airframe's exterior within the periphery, restrict deformation of the skin. The reaction surfaces envelop an external containment cell which provides adequate space for cutting to occur; changing the volume and shape of the external containment cell alters the roughness of the cut. The reaction surfaces also receive impulse forces from the charge to jettison the severed portion of the airframe. Sealing walls and retention surfaces shield the airframe's interior from explosive forces. The pilot initiates the charges by rotating a bellcrank assembly which activates a lanyard-detonator. Safe pilot egress is improved by reducing the roughness of the egress area periphery, and increasing the distance which the severed portion is jettisoned.
