What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
A brake test had been done on the ramp before taxiing and that they had completed the run up holding short of runway 5L with no problems with the brakes. Once they were cleared on to the runway they taxied to the edge of the pavement to perform a short field takeoff. When he applied the right brake to align the aircraft with the centerline, he got no response. He notified his instructor who was sitting in the left seat. He applied his right brake to turn the aircraft and also got no response. At this point the pilot took the power to idle and they worked to stop the aircraft and attempted to avoid hitting any lights. They did end up hitting a runway end identifier light. They informed tower of their issue and that they needed to shut down to be able to turn the aircraft and get it back on the runway. They then proceeded to taxi back to the ramp very slowly as they did not have any right brake. Once they got back on the ramp they shut down and noticed a chip in the propeller and that it was bent. It was also noted that the right main tire was covered in brake fluid.
As the FAA filed it
A BRAKE TEST HAD BEEN DONE ON THE RAMP BEFORE TAXIING AND THAT THEY HAD COMPLETED THE RUN UP HOLDING SHORT OF RUNWAY 5L WITH NO PROBLEMS WITH THE BRAKES. ONCE THEY WERE CLEARED ON TO THE RUNWAY THEY TAXIED TO THE EDGE OF THE PAVEMENT TO PERFORM A SHORT FIELD TAKEOFF. WHEN HE APPLIED THE RIGHT BRAKE TO ALIGN THE AIRCRAFT WITH THE CENTERLINE, HE GOT NO RESPONSE. HE NOTIFIED HIS INSTRUCTOR WHO WAS SITTING IN THE LEFT SEAT. HE APPLIED HIS RIGHT BRAKE TO TURN THE AIRCRAFT AND ALSO GOT NO RESPONSE. AT THIS POINT THE PILOT TOOK THE POWER TO IDLE AND THEY WORKED TO STOP THE AIRCRAFT AND ATTEMPTED TO AVOID HITTING ANY LIGHTS. THEY DID END UP HITTING A RUNWAY END IDENTIFIER LIGHT. THEY INFORMED TOWER OF THEIR ISSUE AND THAT THEY NEEDED TO SHUT DOWN TO BE ABLE TO TURN THE AIRCRAFT AND GET IT BACK ON THE RUNWAY. THEY THEN PROCEEDED TO TAXI BACK TO THE RAMP VERY SLOWLY AS THEY DID NOT HAVE ANY RIGHT BRAKE. ONCE THEY GOT BACK ON THE RAMP THEY SHUT DOWN AND NOTICED A CHIP IN THE PROPELLER AND THAT IT WAS BENT. IT WAS ALSO NOTED THAT THE RIGHT MAIN TIRE WAS COVERED IN BRAKE FLUID.
