NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE PILOT REPORTED THAT AT ABOUT 500 FEET MSL DURING THE INITIAL CLIMB, THE ENGINE LOST POWER. HE STARTED A LEFT TURN BACK TOWARD THE AIRPORT. AFTER CLEARING SOME TREES, THE AIRCRAFT WAS FORCE LANDED IN A GRASSY AREA. AN INSPECTION OF THE AIRCRAFT REVEALED A PIECE OF SILICON BAFFLING MATERIAL, 8 INCHES BY ONE INCH, LODGED INSIDE THE CARBURETOR AIRBOX, WITH 2 INCHES OF THIS MATERIAL EXTENDING INTO THE CARBURETOR VENTURI. WHEN THE MATERIAL WAS REMOVED, THE ENGINE RAN NORMALLY DURING A TEST RUN. THE ORIGIN OF THE FOREIGN MATERIAL COULD NOT BE DETERMINED, AND MAINTENANCE RECORDS DID NOT REVEAL ANY RECENT WORK WHICH WOULD REQUIRE SUCH A MATERIAL.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

A LOSS OF ENGINE POWER DUE TO A PARTIAL BLOCKAGE OF THE INDUCTION AIR SYSTEM BY A FOREIGN OBJECT (SILICON BAFFLING MATERIAL).
