## Probable cause

INADEQUATE SUPERVISION OF THE FLIGHT BY THE FLIGHT INSTRUCTOR (CFI), FAILURE OF BOTH THE STUDENT AND THE CFI TO SEE-AND-AVOID THE STATIC LINE,  AND FAILURE OF THE PILOTS TO MAINTAIN ADEQUATE  CLEARANCE FROM THE POWER LINE/STATIC WIRE.  THE STATIC WIRE WAS A RELATED FACTOR.

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.
