Analysis

DURING A DEPARTURE, THE ENG HAD A PARTIAL LOSS OF POWER. THE PLT REPORTED THAT AFTER CLIMBING TO ABOUT 75 FT, NEITHER THE ACFT'S SPEED NOR ALT WOULD INCREASE. HE LOWERED THE NOSE TO INCREASE THE ENG RPM & SPEED, BUT THE ENG DID NOT RESPOND. SUBSEQUENTLY, THE LEFT WING HIT A TREE & THE ACFT CRASHED INTO ANOTHER TREE & THE GROUND. THE PLT STATED THAT DURING THE TAKEOFF ROLL, THE ACFT HAD NOT ACCELERATED TO ITS TAKEOFF SPEED AT THE MIDPOINT OF THE 3000 FT RWY, YET HE CONTINUED THE TAKEOFF ROLL. AN EXAM REVEALED THAT THE COMPRESSION RING ON THE #1 PISTON WAS FROZEN IN COMPRESSION. NO OTHER PRE-ACCIDENT PART FAILURE OR MALFUNCTION WAS FOUND.
