The airplane was substantially damaged. The two certificated airline transport pilots and five passengers were not injured. Visual meteorological conditions prevailed and an instrument flight rules flight plan was filed for the corporate flight. The airplane was registered to and operated by Sony Aviation Incorporated under the provisions of Title 14 Code of Federal Regulations Part 91. The captain stated that while taxiing southbound on taxiway "Z," the flight crew felt a sudden "big thud/ jolt," and the airplane was brought to a full stop. He said that after checking the passengers, and the status of the airplane, he opened the main entry door and observed that there was damage to the left main wingtip due to a possible collision with a construction steamroller. The steamroller driver stated that he, the wing walker, and other construction crewmembers stopped work to go to lunch. He said after returning from lunch he began to operate the steamroller without having a wing walker present. Shortly thereafter, the airplane struck the upper roller cage and he stopped the steamroller. The steamroller driver further stated that prior to the impact, he did not hear or see the airplane as it approached. Examination of the airplane by a Federal Aviation Administration inspector revealed that the left wingtip and aileron were separated from the wing assembly. ## Aircraft - Registration: [N90TH](https://openairdocs.org/aircraft/N90TH), registered now, S/N 180, built 1999 (OpenAirDocs) - Reported make and model: Dassault Aviation Mystere Falcon 900 - Registry model: [Dassault MYSTERE FALCON 900](https://openairdocs.org/model/dassault-mystere-falcon-900) (registry code 2730172) (OpenAirDocs) - Registry engine: [Alliedsign TFE-731-2B](https://openairdocs.org/engine/alliedsign-tfe-731-2b) (registry code 02502, turbo-jet) (OpenAirDocs) - Category: Airplane - Serial number: 180 - Airframe hours: 3840 - Engines: Allied Signal TFE731-5BR-1C 4750 lbs thrust turbo fan; Allied Signal TFE731-5BR-1C 4750 lbs thrust turbo fan; Allied Signal TFE731-5BR-1C 4750 lbs thrust turbo fan - Damage: Substantial damage - Flight: Executive/Corporate, Part 91 - Registered owner: Sony Aviation Incorporated - Airworthiness certificate: Standard, Transport - Last inspection: Continuous airworthiness, September 1, 2007, 13 hours before - Departed: TEB, TETERBORO, NJ - Destination: SAN, SAN DIEGO, CA - Flight plan: IFR - Airport: TEB, Teterboro ## Flight crew As NTSB recorded them.
