What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot in command (PIC) was taxiing the aircraft for takeoff with a non-certificated passenger in the co-pilots seat. As he was taxiing, the passenger was having difficulty fastening his seat belt, the PIC reached over to assist him with his seat belt while the aircraft was in motion. The aircraft veered off the taxiway, causing the right hand propeller to strike a taxi way light on the taxi way edge which damaged the right hand propeller and the taxi light.
