Factual narrative

THE ACFT LANDING GEAR COLLAPSED DURING A FORCED LANDING DUE TO A CABIN FIRE. THE LANDING OCCURRED JUST SHORT OF THE RWY AT MARATHON ARPT, FL. THE PLT HAD DEPARTED THIS ARPT ABOUT 30 MINUTES EARLIER ON THE 2ND LEG OF A STUDENT X-COUNTRY FLT.THE DEPARTURE WAS AT ABOUT 1105 EDT. AT 1130 WITNESSES SAW THE ACFT APPROACHING THE ARPT WITH FLAMES AND SMOKE VISIBLE INSIDE AND OUTSIDE OF THE ACFT. AFTER THE ACCIDENT THE PLT SAID THAT ABOUT 10 MINUTES AFTER TAKEOFF HE SMELLED SOMETHING AND TURNED AROUND TO SEE THE CABIN ON FIRE. A REVIEW OF THE ACFT LOG SHOWS THAT THE ALTERNATOR WAS REPLACED ON8/2/83. A POST ACCIDENT TEST OF THE ALTERNATOR SHOWED ITS PERFORMANCE WITHIN LIMITS. FUEL LINES IN THE CABIN AND THE FUEL SELECTOR ALONG WITH THE REMAINING D.C. ELECTRICAL HARNESSES WERE SENT TO THE NTSB LAB FOR EXAMINATION. THE LAB FOUND EVIDENCE THAT AN ALUMINUM CABLE WAS INTERNALLY HEATED MOST LIKELY FROM EXCESSIVE ELECTRICAL CURRENT. DUE TO THE FIRE OTHER COCKPIT EVIDENCE WAS DESTROYED. BASED UPON STATEMENTS THE FIRE ORIGINATED IN THE REAR OF THE ACFT. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
