## Analysis

THE PILOT WAS EXECUTING A POWER-OFF GLIDE AND WHEN AN ATTEMPT WAS MADE TO RECOVER BY ADDING POWER, THE ENGINE DID NOT RESPOND. THE PILOT WAS THEN FORCED TO MAKE AN EMERGENCY LANDING IN A FIELD. DURING THE FORCED LANDING THE PILOT WAS UNABLE TO MAINTAIN CONTROL AND SUBSEQUENTLY CAUGHT A WINGTIP ON THE ROUGH TERRAIN AND CARTWHEELED THE AIRCRAFT. AS A RESULT THE AIRCRAFT WAS DESTROYED. INVESTIGATION OF THE ENGINE BY AN FAA INSPECTOR REVEALED THAT THE CARBURETOR WAS CONTAMINATED WITH A FIBERGLASS SUBSTANCE WHICH BLOCKED THE THROAT OF THE CARBURETOR. THERE WERE NO OTHER SIGNS OF THE SUBSTANCE AND AS A RESULT THE PLACE OF ORIGIN OF THE SUBSTANCE COULD NOT BE DETERMINED.
