What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Aircraft was dispatched on an air ambulance flight. Co-pilot began taxi and used excessive thrust to taxi over ground power cord that runs to the air ambulance helicopter parked next to the Learjet. Jet blast caused two Cessna 172 aircraft to be blown into each other causing substantial damage to both Cessna 172S. The Cessna 172 aircraft were parked with their tails towards the Learjet, which is contrary to FBO policy and the FBO agreement with the air ambulance operator.
