## Narrative

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

THE AIRMAN DESCENDED FROM EN ROUTE ALTITUDE AND CONFIGURED THE AIRCRAFT FOR LANDING. AT APPROXIMATELY 1,800 FEET MSL, THE AIRMAN SLOWED THE AIRCRAFT TO BELOW 97 KIAS AND EXTENDED THE FLAPS FROM 50 PERCENT TO 100 PERCENT. A LOUD BANG OR POP WAS HEARD, FOLLOWED BY AN ASYMMETRIC FLAP FAILURE THAT RESULTED IN A RAPID RIGHT ROLLING MOTION AND LOSS OF AIRCRAFT CONTROL. THE AIRMAN DEPLOYED THE CIRRUS AIRCRAFT PARACHUTE SYSTEM (CAPS). THE AIRCRAFT CAME TO REST NOSE DOWN IN A WOODED AREA.

## NTSB investigation

None matched to this report by aircraft and date. Search the NTSB's own records: https://data.ntsb.gov/carol-main-public/basic-search

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.
