## Narrative

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

DURING DESCENT FOR A LANDING, PILOT EXTENDED THE FLAPS TO FULL.  WITHIN A FEW SECONDS, THE RIGHT FLAP PARTIALLY RETRACTED CAUSING PILOT TO USE ALMOST FULL AILERON DEFLECTION TO CONTROLL AIRCRAFT.  PILOT LANDED WITHOUT ANY INCIDENT.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
