What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On December 11, 2011, at 2038 pacific standard time, a Bombardier BD-100-1A10 (challenger 300), N54HA, registered to and operated by orange hawk express, inc, kirkland, Washington, as a title 14 code of federal regulations (CFR) part 91 flight collided with a parked Gulfstream G-550, cs-dkf, as it was being marshaled into parking by ramp personnel at the King county international airport, Boeing field, Seattle, WA. There were no injuries. Night visual meteorological conditions prevailed at the time. The Bombardier BD-100-1A10 (challenger 300) originated from the long beach municipal airport, (lgb), long beach, California, at approximately 1800 pacific standard time, on December 11, 2011. The purpose of the flight was described as a private transport flight for the owners of the aircraft. In a statement provided to the federal aviation administration inspector-in-charge, the pilot in command stated that he was moving the aircraft with reference to the commands of a marshaller, who was positioned ahead and was directing the pilot in command to pull ahead into a parking area with lighted wands. The pilot in command noted the presence of wing walker standing by the left wing. The pilot in command stopped and shut down the aircraft after a "bump" was felt similar to "rolling over a chock". Inspection revealed that the left wing tip had impacted the nose of the parked Gulfstream 550. In a separate statement provided to the federal aviation administration inspector-in-charge by the fixed base operator, the wing walker who was positioned off the left wing of the Bombardier BD-100-1A10 (challenger 300), attempted to signal the lead marshaller with hand and radio signals prior to impact, but could not successfully establish communication in time. The lead marshaller stated that from his position the left wing tip had already cleared the nose of the parked Gulfstream 550, and he had lost sight of the wing walker's hands. The wing walker was not using lighted wands. Once the aircraft were separated, they were both secured for further examination and maintenance action. Both aircraft were visually examined the following morning by federal aviation administration inspectors. Extensive scraping was observed on the left leading edge tip and winglet of the Bombardier BD-100-1A10 (challenger 300). The radome of the Gulfstream 550 had been fractured and a crescent shape gash was noted on the forward and left side of the radome. The resuts of the damage were communicated to the national transportation safety board, who determined the event classification as an incident.
