UAS WAS AT PA34?S 12 O?CLOCK POSITION AND CAUSED THE PILOT OF THE PA34 TO DIVE 100 FEET IN ORDER TO AVOID IT RESULTING IN A NEAR MID-AIR COLLISION (NMAC).  ATC CONTACTED LOCAL LAW ENFORCEMENT WHO CONDUCTED A SEARCH OF THE GROUND AREA NEAR THE SIGHTING OF THE UAS.  NO UAS OPERATOR WAS IDENTIFIED.  INSUFFICIENT INFORMATION IS AVAILABLE TO PURSUE AN INVESTIGATION.  REFER TO NMAC REPORT # NGLTCPS21001.

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.
