The certificated commercial pilot was not injured. Visual meteorological conditions prevailed and no flight plan had been filed for the flight that departed South Jersey Regional Airport (VAY), Mount Holly, New Jersey, destined for the New Garden Airport (N57), Toughkenamon, Pennsylvania. The ferry flight was conducted under 14 CFR Part 91. In a telephone interview, the pilot stated he performed a normal pre-flight inspection and engine run-up prior to takeoff. Approximately 7 to 10 minutes after takeoff, while in cruise flight about 1,400 feet msl., the pilot heard a "loud bang" and experienced severe vibration. He then shut down the engine and performed a forced landing to a field. The airplane nosed over during the landing and came to rest inverted. The wreckage was examined by a Federal Aviation Administration inspector. The inspector stated that one of the airplane's wooden propeller blades had split down it's longitudinal axis and separated in-flight. The remainder of the propeller remained attached to the engine. According to the owner, the propeller installed on the airplane was uncertificated and built specifically for the accident airplane, which was a replica of a World War I fighter. The airplane, engine, and propeller had been operated for about 3 hours of flight time, and 5 to 7 hours of ground tests. ## Aircraft - Registration: [N1893](https://openairdocs.org/deregistered/N1893-2002-10-15), registration cancelled 2002-10-15, S/N PM7668, built 1999 (OpenAirDocs) - Reported make and model: Musso Nieuport 24 - Registry model: [Musso Paul A NIEUPORT 24 BIS](https://openairdocs.org/model/musso-paul-a-nieuport-24-bis) (registry code 0564031) (OpenAirDocs) - Registry engine: [Warner SS165 series](https://openairdocs.org/engine/warner-ss165-series) (registry code 64504, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: PM7668 - Airframe hours: 7 - Engines: Warner SS 165 165 horsepower reciprocating - Damage: Substantial damage - Flight: Ferry, Part 91 - Registered owner: Paul A.
