From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry 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.
What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On November 13, 2004, at 1418 PST, N502GL a model 2T-1A great lakes aircraft ground looped during landing rollout runway 28L, Montgomery airfield, San Diego CA. The flight was conducted under the provision of 14 CFR part 91. The pilot stated that during rollout he applied brakes but the left did not activate which caused the aircraft to depart the runway to the right. The soft ground caused N502GL to tip on the left lower wing and nose over. The aircraft was substantially damaged, the pilot and student pilot were not injured. Investigation revealed the left brake felt soft when activated (front and rear cockpit brake levers) however no mechanical abnormalities were noted. Possible air or bypass condition. M or d will be submitted.
