THIS WAS THE 2ND OF 3 POSSIBLE FLIGHTS SCHEDULED FOR THIS AIRCRAFT TO PROVIDE PROFICIENCY & CURRENCY TRAINING FOR AN FAA INSPECTOR. AFTER A PREFLIGHT INSPECTION AND RUNUP, THE FLIGHT INSTRUCTOR (CFI) & FAA INSPECTOR TAXIED TO THE SOD RUNWAY (RUNWAY 13) FOR TAKEOFF. AS THE AIRPLANE ACCELERATED, THE FAA INSPECTOR NOTICED THE ENGINE WAS NOT DEVELOPING FULL TAKEOFF POWER & INFORMED THE CFI. ACCORDING TO THE FAA INSPECTOR, THE CFI REACHED OVERHEAD (APPARENTLY) TO ADJUSTED THE MIXTURE CONTROL & INSTRUCTED THE FAA INSPECTOR TO CONTINUE THE TAKEOFF. AS THE AIRSPEED APPROACHED 60 KNOTS, THE FAA INSPECTOR WAS INSTRUCTED TO ROTATE. A WITNESS NEAR THE DEPARTURE END OF THE RUNWAY OBSERVED THE AIRPLANE AS IT BECAME AIRBORNE & NOTICED A REDUCTION IN ENGINE RPM AFTER LIFTOFF. SUBSEQUENTLY, THE AIRCRAFT SETTLED & COLLIDED WITH TREES ABOUT 700' BEYOND THE END OF THE RUNWAY. AN EXAM OF THE AIRCRAFT & ENGINE FAILED TO REVEAL A MECHANICAL PROBLEM. THE WIND WAS REPORTED TO BE FROM 290 DEGREES AT 7 KNOTS.
Probable Cause: LOSS OF ENGINE POWER FOR AN UNDETERMINED REASON. A FACTOR RELATED TO THE ACCIDENT WAS: IMPROPER PLANNING/DECISION BY THE FLIGHT INSTRUCTOR (CFI).
