NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

DURING A PRACTICE EMERGENCY APPROACH, THE AIRCRAFT STRUCK A STATIC WIRE ON A POWER LINE. IT THEN DESCENDED INTO TREES & TERRAIN & WAS DAMAGED. BOTH THE INSTRUCTOR & THE STUDENT STATED THAT BEFORE IMPACT, ONLY THE MAIN POWER LINES & TOWERS WERE VISIBLE. THEY DID NOT SEE THE STATIC LINE & THOUGHT THAT THEY WOULD BE CLEAR OF THE WIRES.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

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.
