## Analysis

THE PILOT REPORTED THAT AFTER TAKEOFF, HE MADE A FEW TURNS AND THEN HEADED DOWNWIND FOR A LANDING WHEN HE LOST THE CONTROL OF AN AILERON. HE REPORTED THAT HE ENCOUNTERED A BAD VIBRATION, SO HE CUT THE POWER AND BROUGHT THE PLANE INTO A SMALL FIELD BY CROSSING UNDER HIGH POWERLINES. DURING THE LANDING, THE LEFT WING HIT SMUDGE POTS AND THE AIRCRAFT CARTWHEELED. AN INVESTIGATION REVEALED THAT THE LEFT AILERON, PUSH-PULL, ROD ASSEMBLY HAD PULLED LOOSE FROM THE ATTACHING SLEEVE AT THE BELL CRANK ATTACH POINT. THE ROD HAD BEEN BRAISED INTO THE SLEEVE RATHER THAN BEING RIVETED. THIS FAILURE RESULTED IN LOSS OF HALF OF THE AILERON AUTHORITY. THE PILOT WAS THE OWNER AND BUILDER OF THE AIRCRAFT.
