Narrative

While in movement on ramp; C172 was taxiing toward hangar at FBO when E55P throttled up to begin taxi to taxiway from ramp. E55P was positioned nose facing west; with exhaust pointed toward car parking area and hangars; C172 was positioned facing east behind E55P oriented tail to tail; moving away from other aircraft. When E55P added power to begin moving; C172 was struck with jet thrust to aft of airframe and put into a ground spin to the right. C172 spun approximately 270 degrees and came to rest facing FBO entrance (north). At no time did the affected aircraft come in to contact with persons or property. After incident; C172 was unable to turn to the right to taxi to hangar; but was able to turn to the left 270 degrees to continue taxi to hangar area under its own power. Pilot of C172 was unable to control aircraft in spin phase of incident; but was able to hold brakes until aircraft stopped. Pilot of C172 did not see any ramp personnel directing E55P; was not personally under direction of ramp personnel; and had no indication power up was imminent. No injuries were sustained to pilot or passenger of C172; and no third party persons or property were damaged to pilots knowledge.
