The road sign was a factor. ## 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, approach - engine assembly,master rod - failure,total (cause) - Forced landing, emergency descent/landing - On ground/water collision with object, emergency descent/landing - object - sign (contributing factor) ## Analysis The airplane was damaged when it struck a road sign during a forced landing to a road following a complete loss of engine power. Examination of the airplane revealed that the radial engine's master connecting rod had failed. ## Factual narrative On July 22, 2007, about 1943 central daylight time, a North American T-6G, N22NA, piloted by an airline transport pilot, sustained substantial damage during a forced landing near Fond Du Lac, Wisconsin, following a loss of engine power. The 14 CFR part 91 flight was operating in visual meteorological conditions without a flight plan. No injuries were reported. The flight's origin was was not reported. The Fond Du Lac County Airport was the intended destination. After the loss of engine power the pilot executed a forced landing on the northbound lanes of U.S. Highway 41. A Wisconsin State Highway Patrol car heading northbound captured the landing on the car's on-board video camera. The video was broadcast on various television news networks and on the internet. The video showed the airplane landing amongst vehicle traffic. During the landing, the airplane struck a road sign which caused substantial damage to the right wing. An examination of the airplane subsequent to the accident revealed that the radial engine's master connecting rod had failed. As of November 27, 2007, the pilot had not submitted a report of the accident to the NTSB. ## Aircraft - Registration: [N22NA](https://openairdocs.org/aircraft/N22NA), registered now, S/N 49-3222, built 1946 (OpenAirDocs) - Reported make and model: North American T-6G - Registry model: [North American T-6G](https://openairdocs.org/model/north-american-t-6g) (registry code 6400432) (OpenAirDocs) - Registry engine: [Pratt & Whitney R1340 series](https://openairdocs.org/engine/pratt-whitney-r1340-series) (registry code 52016, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 49-3222 - Engines: Pratt & Whitney R-1340 600 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Departed: Unknown - Destination: Fond Du Lac, WI ## Flight crew As NTSB recorded them.
