## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(.19) ON AUGUST 17, 2002, ABOUT 1330 EASTERN DAYLIGHT TIME, A BELLANCA 8GCBC, N86714, WAS SUBSTANTIALLY DAMAGED DURING A FORCED LANDING IN GUILFORD, CONNECTICUT. THE CERTIFICATED COMMERCIAL PILOT WAS NOT INJURED, AND VISUAL METEOROLOGICAL CONDITIONS PREVAILED AT THE TIME. NO FLIGHT PLAN HAD BEEN FILED FOR THE LOCAL FLIGHT, FROM SKYLARK AIRPORT (7B6), EAST WINDSOR, CONNECTICUT. THE BANNER TOW FLIGHT WAS CONDUCTED UNDER 14 CFR PART 91. ACCORDING TO A FEDERAL AVIATION ADMINISTRATION (FAA) INSPECTOR, THE AIRPLANE WAS CRUISING AT AN ALTITUDE OF 1,200 FEET WHEN THE ENGINE LOST POWER. THE PILOT JETTISONED THE BANNER, AND CONDUCTED THE FORCED LANDING TO A FIELD. DURING LANDING ROLLOUT, THE AIRPLANE FLIPPED OVER. A POST-FLIGHT EXAMINATION OF THE ENGINE REVEALED THAT THE NUMBER 3 CYLINDER WAS CRACKED BETWEEN THE NUMBER 3 AND NUMBER 4 FINS. IN ADDITION, THE NUMBER 3 CYLINDER EXHAUST VALVE WAS SEIZED. (-23) DURING A BANNER TOW FLIGHT THE AIRCRAFT EXPERIENCED ENGINE PROBLEMS. THE PILOT FOUND AN OPEN FIELD AND DROPPED THE BANNER, THEN HE FOUND ANOTHER OPEN FIELD AND LANDED. ON ROLLOUT, THE PILOT BRAKED HARD AND THE AIRCRAFT                                                                         FLIPPED OVER. INVESTIGATION FOUND THE #3 CYLINDER CRACKED BETWEEN THE #3 AND #4 FIN AND THE EXHAUST VALVE WAS STUCK. THE LAST ENGINE ANNUAL WAS COMPLETED 3/14/02. THE AIRCRAFT TOTAL TIME WAS 4520.43 HOURS. TOTAL TIME SINCE CYLINDER WAS CHANGED AT 625 HOURS. THE LAST ENGINE OVERHAUL WAS AT 2089 HOURS. THE WING ATTACH FITTING WAS DAMAGED AND THE VERTICAL FIN BENT. THE LYCOMING REP CHECKED THE ENGINE AND FOUND THE VALVE GUIDES WITH VARNISHED COMPOUND AROUND THEM. THIS CAUSED THE VALVE TO STICK THUS FORMING BACK PRESSURE AND THE CASE TO FAIL.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
