The NTSB's narrative final · quoted from the NTSB record
THE PILOT STATED THAT JUST AFTER TAKEOFF, AND ABOUT 10 FEET ABOVE THE GROUND, THE ENGINE GRADUALLY LOST PARTIAL POWER, AND THE AIRPLANE CRASHED INTO THE BUSHES JUST OFF THE END OF THE REMOTE STRIP. INFORMATION SURROUNDING THE ACCIDENT WAS VERY MINIMAL AND SKETCHY. SEVERAL UNSUCCESSFUL ATTEMPTS WERE MADE TO GET MORE INFORMATION FROM THE PILOT AND PASSENGER. THE WRECKAGE WAS NOT RECOVERED, AND THE CAUSE OF THE POWER LOSS WAS NOT DETERMINED.
