# NTSB NYC03LA101: Bombardier CL-600-2B19, N484CA, Boston, MA, May 7, 2003 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 7, 2003, 12:15 local (16:15 UTC) - Place: Boston, MA - Coordinates: 42.366943, -71.008613 - Nearby events: https://openairdocs.org/map.md?lat=42.3669&lon=-71.0086&mi=10 - Phase of flight: [Standing](https://openairdocs.org/ntsb-phases/150) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report June 30, 2004 - Report: Approved by Office Director - Parties: FAA FSDO-01 - NTSB case key (mKey): 56953 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC03LA101 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/56953/pdf - Page: https://openairdocs.org/ntsb/NYC03LA101 ## Probable cause The operator's loss of control of the belt-loader while operating in the proximity of the airplane. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Miscellaneous/other, standing - engine(s) not operating - equipment,other - uncontrolled, driver of vehicle (cause) ## Analysis The airplane was chocked, the seat belt sign had been turned off, and the passengers were disembarking. As the operator of a belt-loader approached the airplane, he tested the brakes, and they operated normally. When the belt-loader was about 3-4 feet from the airplane, the belt-loader operator again applied the brakes; however, they were either jammed or stuck, and would not work. He switched the transmission into neutral, but the belt-loader continued to roll forward, until it struck the fuselage of the airplane. The belt-loader operator further stated that he did not think to use the emergency brake. Post-accident examination of the belt-loader revealed no mechanical discrepancies. ## Factual narrative On May 7, 2003, at 1215 eastern daylight time, a Bombardier CL-600-2B19, N484CA, operated by Comair Inc., as flight 5347, was substantially damaged when a baggage belt-loader collided with it, while parked at the General Edward Lawrence Logan International Airport (BOS), Boston, Massachusetts. There were no injuries to the 3-person crew, or the operator of the belt-loader. Visual meteorological conditions prevailed at the time of the accident. An instrument flight rules flight plan was filed for the flight, between the Ronald Reagan Washington National Airport, Washington, DC, and Boston. The scheduled passenger flight was conducted under 14 CFR Part 121. The airplane was chocked, the seat belt sign had been turned off, and the passengers were disembarking. The operator of the belt-loader stated that when he initially approached the airplane with the belt-loader, he tested the brakes and they operated normally. When the belt-loader was about 3-4 feet from the airplane, he again applied the brakes; however, they were either jammed or stuck. He switched the transmission into neutral, but the belt-loader continued to roll forward, until it struck the fuselage of the airplane. The belt-loader operator further stated that he did not think to use the emergency brake. A Federal Aviation Administration (FAA) inspector reported that the loader had punctured the fuselage about 2 feet below the cargo door threshold, creating a 15-inch by 9-inch hole. Additionally, two stringers were damaged. Post-accident examination of the belt-loader revealed no mechanical discrepancies. ## Aircraft - Registration: N484CA (not matched to a registry record) - Reported make and model: Bombardier CL-600-2B19 - Category: Airplane - Serial number: 7702 - Airframe hours: 1449 - Engines: General Electric CF-34-3B1 9220 lbs thrust turbo fan; General Electric CF-34-3B1 9220 lbs thrust turbo fan - Damage: Substantial damage - Flight: Part 121 - Registered owner: Comair Inc - Airworthiness certificate: Standard, Transport - Last inspection: Continuous airworthiness, May 2, 2003, 51 hours before - Departed: DCA, Washington, DC - Destination: BOS, Boston, MA - Flight plan: IFR - Airport: BOS, Logan International Airport ## Flight crew As NTSB recorded them.
