What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Part 65/91 operation Cirrus SR20, registration privacy data omitted serial number 2775, with two pilots and one passenger, was struck by lightning while preforming engine run-up on taxiway. No injuries to aircraft occupants. Light strike causing parachute rocket recovery system to activate and launching. Light strike struck comm 1 antenna flowing thru aircraft exiting main landing gear. The lighting discharge left 3 cone shape holes and pavement fragments next to aircraft main landing gear.
Cfi/pilot stated they were in the designated runup area east of taxiway N8 at kopf. Shortly after they had finished our runup, decided to listen to the new ATIS broadcast that ground control advised all aircraft was current. Just as they listened to ATIS they saw a flash and an immediate loud bang that shook the entire airplane. Cfi/pilot stated noticing a bit of smoke coming from the cargo area and thought at first that there may have been a potential fire in the tail section and did notice something moving around the empennage. Shutting the engine down and secured the fuel valve, realized that the sulfur smell was from the caps system ballistic rocket which the lighting strike had triggered the caps system to deploy.
