A factor relating to the accident was: the airplane encountered uneven terrain during a forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - mech failure/malf, cruise - lubricating system,oil filter/screen - stripped thread (cause) - maintenance - inadequate (cause) - lubricating system,oil filter/screen - separation (cause) - fluid,oil - exhaustion (cause) - Forced landing, emergency descent/landing - On ground/water encounter with terrain/water, landing - roll - terrain condition - drop-off/descending embankment ## Analysis The pilot reported that he was operating the airplane over a fairground area, towing a banner, when he noted a complete loss of oil pressure. He stated that he tried to return to the airport, but the engine lost power. He made a forced landing in a freshly mown hay field. The pilot reported that the airplane encountered a drop off during the forced landing/landing roll and was damaged. Postaccident examination revealed that the oil filter adapter had separated from a boss on the crankcase cover. An FAA Inspector stated that about 80% of the threads in the crankcase cover boss were stripped. ## Factual narrative On August 26, 1995, at 1912 eastern daylight time, a Cessna R172K, N1439V, lost engine power and made a forced landing in an open field at Lisbon, Ohio.
