## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) THIS INCIDENT DID NOT COME TO THE ATTENTION OF THE FAA UNTIL JULY 12, 2007 AFTER THE AIRCRAFT HAD BEEN MOVED AND WORKED ON. THE CFI PIC FROM MONTGOMERY AVIATION AT GAI WAS TAXIING OUT FOR A FAR PART 61 INSTRUCTION FLIGHT WITH A POTENTIAL STUDENT IN THE RIGHT SEAT. HE SAID THAT HE DID A THOROUGH PRE-FLIGHT AND TESTED THE BRAKES SATISFACTORILY AS HE STARTED HIS TAXI. DURING TAXI, HE HAD HIS FEET ON THE RUDDER AND BRAKES AND WAS TRYING TO TAXI SLOW. HE ALSO SAID HE WAS COMPENSATING FOR THE AIRCRAFT'S DESIRE TO DRIFT RIGHT BY USING LEFT RUDDER. HE SAID HE FELT THE RIGHT BRAKE GRAB AND THE AIRCRAFT VEERED TO THE RIGHT AND IMPACTED THE SECOND AIRCRAFT BEFORE HE COULD ACT. HIS RECOLLECTION OF WHAT TRANSPIRED WAS VAGUE AS HE SAID IT ALL HAPPENED SO FAST. DURING MY INVESTIGATION I QUESTIONED THE CHIEF INSPECTOR OF MONTGOMERY AVIATION AND HE SAID THAT N52870'S BRAKES CHECKED GOOD AFTER THE INCIDENT. ^PRIVACY DATA OMITTED^

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
