## Analysis

PILOT STATED THAT WHILE DEPARTING FROM A SMALL 2000 FOOT LONG PRIVATE STRIP THE ENGINE APPEARED TO LOOSE POWER. THE AIRCRAFT WOULD NOT CLIMB AND COLLIDED WITH A TREE AT THE DEPARTURE ENS OF THE RWY. THE ACFT THEN COLLIDED WITH SEVERAL OTHER TREES PRIOR TO COLLIDING WITH THE GRND. POST CRASH RUNNING OF THE ENG REVEALED NO EVIDENCE TO INDICATE ANYPRECRASH MECHANICAL FAILURE OR MALFUNCTION. WITNESSES STATED THAT AFTER LIFT-OFF THE ACFT APPEARED TO LEVEL OFF AT 10 TO15 FT AGL AND FLEW STRAIGHT AHEAD COLLIDING WITH THE TREES. THERE WAS NO ATTEMPT TO AVOID THE TREES WHICH HAD CLEAR AREAS ON BOTH SIDES. IN A WRITTEN STATEMENT, THE PLT REPORTED LIFTING OFF AT 80 KTS, BUT IN A VERBAL STATEMENT, HE SAID HE HAD LIFTED OFF AT 40 KTS. ALSO, A WITNESS SAID THE GEAR STARTED RETRACTING JUST AFTER LIFT-OFF. ACCORDING TO THE PLT'S HANDBOOK, THE MAX PERFORMANCE CLIMB SPEED WAS 72 KTS & THE GEAR SHOULD HAVE BEEN RETRACTED AFTER OBSTACLES HAD BEEN CLEARED.
