CONTRIBUTING TO THE ACCIDENT WAS THE DIVERTION OF ATTENTION OF THE PILOT IN COMMAND TO THE AIRPLANE ON THE APCH END OF THE RWY. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, cruise - normal - engine assembly,valve,exhaust - failure,total (contributing factor) - engine assembly,valve,exhaust - undetermined (contributing factor) - Forced landing, descent - emergency - On ground/water collision with object, landing - roll - diverted attention, pilot in command (contributing factor) - object - tree(s) - directional control - not maintained, pilot in command (cause) ## Analysis DURING CRUISE FLT WITH THE STUDENT PLT FLYING THE ACFT, THE ENG EXPERIENCED A PARTIAL LOSS OF POWER. THE CFI TOOK CONTROL OF THE ACFT & WAS ADVISED BY ATC THAT A GRASS AIRSTRIP WAS BELOW. THE FLT CIRCLED WHILE DESCENDING & THE CFI ASKED ON THE UNICOM FREQUENCY IF ANYONE WAS MONITORING IT BUT RECEIVED NO REPLY. WHILE CIRCLING HE OBSERVED AN ACFT TAKE OFF TO THE SOUTH & ELECTED TO LAND IN THAT DIRECTION. WHILE ON A MODIFIED FINAL APCH, HE OBSERVED AN ACFT ON THE APCH END OF THE RWY. AFTER LANDING APRX 1/2 WAY DOWN THE 2,300 FT GRASS/SAND RWY, THE ACFT TRAVELLED OFF THE RT SIDE & COLLIDED WITH A TREE.
