NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

THE PLT STATED THAT START, TAXI & TAKEOFF WERE NORMAL UNTIL AFTER HE RAISED THE GEAR HANDLE & THE ACFT WAS CLIMBING THRU APRX 150 TO 200 FT AGL. AT THAT TIME, HE NOTICED THAT THE LEFT ENG RPM WAS DECAYING. THERE WAS INSUFFICIENT RWY REMAINING TO ABORT, SO HE ELECTED TO FEATHER THE LEFT ENG & CONTINUE THE TAKEOFF. THE LEFT PROP STOPPED ROTATING BEFORE IT FEATHERED. WITH ADDITIONAL DRAG FROM THE LEFT PROP, THE ACFT WOULD NOT CLIMB OR MAINTAIN LEVEL FTL. THE PLT WAS ABLE TO FLY THE ACFT OVER BUILDINGS & OTHER OBSTACLES (UP TO 75 FT TALL) NEAR THE ARPT BOUNDRY. JUST BEYOND THESE OBSTACLES, THE ACFT STRUCK TREES & CRASHED IN A WOODED AREA. THERE WAS A SMALL POST-IMPACT FIRE NEAR THE ACCESSORY SECTION OF THE RIGHT ENG. AN EXAM & TEARDOWN OF THE LEFT ENG REVEALED THAT AN IMPELLER SHAFT BEARING, PRATT & WHITNEY PART NUMBER 288943, HAD FAILED & ALLOWED THE IMPELLER TO RUB AGAINST THE DIFFUSER. NO OTHER PREIMPACT FAILURES WERE FOUND.
