BELLANCA 17-30A
WHILE THE ACFT WAS FLYING OVER WOODED TERRAIN, THE ENG LOST POWER. THE PLT SAW A PLOWED FIELD APRX 3 MI AWAY & BEGAN AN EMERG APCH TO THE FIELD. THE ACFT STRUCK THE TOPS OF TREES ON FINAL APCH, BUT CONTINUED FLYING UNTIL THE PLT MADE A GEAR UP LANDING. AN EXAM REVEALED THAT THE EXHAUST MUFFLER HAD FAILED AT A WELD WHERE A BALL JOINT WAS CONNECTED. THIS ALLOWED HOT EXHAUST GASES TO ENTER THE ENG COMPARTMENT, BURN THE MAGNETO WIRES & RENDER THE MAGNETOS INOPERATIVE. AN AIRWORTHINESS DIRECTIVE, AD 76-23-03, WHICH REQUIRED AN INSPECTION OF THE EXHAUST SYS EACH 100 HRS, HAD BEEN COMPLIED WITH ON 10/7/83, BUT HAD NOT BEEN PERFORMED DURING THE LAST ANNUAL INSPECTION ON 12/7/84. THE ACFT HAD ACCUMULATED 68 HRS OF FLT TIME SINCE COMPLIANCE WITH AD 76-23-03.
