# NTSB MIA98LA242: Cessna 177RG, N2679V, Covington, GA, September 5, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: September 5, 1998, 11:19 local (15:19 UTC) - Place: Covington, GA - Location: 33.6054° N, 83.8466° W: Placed by OpenAirDocs: center of Covington, GA, within about 6 miles (OpenAirDocs) - Nearby events: https://openairdocs.org/map.md?lat=33.6054&lon=-83.8466&mi=10 - Phase of flight: [Unknown](https://openairdocs.org/ntsb-phases/990) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report March 30, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 43907 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA98LA242 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/43907/pdf - Page: https://openairdocs.org/ntsb/MIA98LA242 ## Probable cause slippage of the No. 3 connecting rod bearing resulting in blockage of the oil port, oil starvation, and subsequent connecting rod failure. A factor was the fence. ## 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, unknown - engine assembly,bearing - slipped (cause) - lubricating system,oil port/passage,internal - blocked(total) - fluid,oil - starvation - engine assembly,connecting rod - failure - Forced landing, emergency landing - On ground/water collision with object, landing - roll - object - fence ## Analysis The pilot reported that about 10 minutes after takeoff he experienced a loss of indicated engine oil pressure. The engine began to run rough and seized about two miles short of his divert airport. The pilot initiated an emergency landing in a grass field and during the landing rollout, the airplane collided with a fence. Subsequent examination of the engine revealed the No. 3 connecting rod bearing had become unsecured and rotated about its installed location ultimately blocking its lubrication port. The No. 3 connecting rod failed and a hole was observed in the crankcase adjacent to the No. one cylinder. ## Factual narrative On September 5, 1998, about 1119 eastern daylight time, a Cessna 177RG, N2679V, registered to Mile High Aviators, LLC., operating as a 14 CFR Part 91 personal flight, crashed in a field during a forced landing following an engine failure, near Covington Municipal Airport, Covington, Georgia. Visual meteorological conditions prevailed and no flight plan was filed. The airplane received substantial damage and the private-rated pilot, the sole occupant, was not injured. The flight originated from Atlanta about 1101 the same day. According to the pilot, about 10 minutes after takeoff, just after activating his flight plan to St. Simons Island, Georgia, with Atlanta Approach Control, he experienced a loss of indicated engine oil pressure. The pilot was being vectored to the Covington airport when the engine started to run rough and seized about 2 miles short of the airport. The pilot felt his only option was to execute an emergency landing to a grass field. The airplane collided with a fence on landing rollout. Postcrash examination of the engine by an FAA inspector revealed a large hole in the crankcase next to the No. 1 cylinder, and chunks of metal on top of the heater muff hose. Subsequent disassembly examination of the engine revealed that the No. 3 connecting rod bearing had become unsecured and spun about its installed location, plugging its lubrication oil source, and causing failure of the No. 3 connecting rod. Large chunks of metal within the crankcase and oil system caused subsequent blockage and additional internal failure.
