(-23) THE PILOT-IN-COMMAND (PIC) REPORTED THE AIRCRAFT ENGINE SURGED JUST AFTER HIS 0900L TAKEOFF FROM ENTERPRISE AIRPORT, AL (EDN) ON SEPTEMBER 19, 1999. THE SOUND OF THE ENGINE SURGE WAS WITNESSED BY SEVERAL BYSTANDERS. HE ATTEMPTED A RETURN TO EDN FOR AN EMERGENCY LANDING BUT REPORTED AN INBOUND CESSNA 150 FLEW UNDER HIS PATH CAUSING HIM TO ABORT. THE ENGINE FAILED DURING HIS SECOND ATTEMPT TO LAND. HE MANAGED TO SET THE AIRCRAFT DOWN AT 0925L IN AN UN-TILLED FIELD APPROX. 3/4 OF A MILE OFF THE APPROACH END OF RUNWAY 05. THE PIC WAS ABLE TO EXIT THE WRECKAGE JUST BEFORE IT ENGULGING INTO FLAMES. A WITNESS ARRIVED MOMENTS LATER TO ASIST HIME AND SUBSEQUENTLY TOOK HIM TO THE AIRPORT TO WASH CHEMICALS OUT OF THIS EYES. HE WAS LATER TRANSPORTED TO A LOCAL HOSPITAL AND TREATED FOR MINOR INJURIES BEFORE BEING RELEASED. THERE WAS NO RADIO CONTACT BETWEEN THE CESSNA 150 AND THE ACCIDENT AIRCRAFT (6736Q). THE ACCIDENT AIRCRAFT WAS NOT EQUIPPED WITH A RADIO, ACCORDING TO THE PIC. "SEE ATTACHED" (.4) ACCORDING TO THE PILOT, HE DEPARTED ENTERPRISE AIRPORT WITH A FULL LOAD OF CHEMICALS FOR AERIAL APPLICATION TO A NEARBY COTTON FIELD. SHORTLY AFTER TAKEOFF, THE ENGINE BEGAN TO SURGE . HE ADJUSTED THE PROPELLER LEVER CONTROL TO THE 'HIGH' POSITION AND TURNED THE FUEL BOOST PUMP 'ON.' HE ELECTED TO RETURN TO THE AIRPORT AND WHILE ON SHORT FINAL HE OBSERVED ANOTHER AIRPLANE PASS BENEATH HIM. HIS AIRPLANE, ALTHOUGH SURGING, HAD BEEN PRODUCING SUFFICIENT POWER THEREFORE, HE EXECUTED A LEFT 360 DEGREE TURN FOR SPACING. WHEN THE TURN WAS NEARLY COMPLETE, THE ENGINE LOST ALL POWER AND HE MANEUVERED FOR AN OPEN FIELD. THE AIRPLANE COLLIDED WITH A TREE AND THEN THE GROUND. EXAMINATION OF THE WRECKAGE REVEALED THAT THE WINGS, EMPENNAGE, AND FUSELAGE WERE DESTROYED ALMOST BEYOND RECOGNITION. THE ONLY RECOGNIZABLE PORTION OF THE ENGINE WAS THE POWER SECTION AND THE ENTIRE TURBINE SECTION WAS DESTROYED. A FUEL SAMPLE OF THE JET-A FUEL USED IN THE AIRPLANE SHOWED NO VISIBLE EVIDENCE OF CONTAMINATION. THE AIRPLANE AND ENGINE WERE CONSUMED BY FIRE. ## The NTSB's investigation of this event (1) From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
