The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

The combination of the left turn and only the right brake operating caused the aircraft to vear off of the taxiway to the right. The main landing geat hit a taxiway light, damaging the light. No damage to the aircraft. The aircraft was returned to the FBO where the brake system was worked on. The aircraft departed later in the day.
