What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-5) Challenger CL-604, N667LC, crew was in aircraft performing pre-flight check when they felt sudden jarring sensation (bump). They wondered if they had been struck by the adjacent Gulfstream g-iii, N100HG, beginning to taxi to depart the ramp. Challenger crew looked outside to discover that, in fact, they had been struck by the g-iii. Approximately 6-7" of the challenger's winglet had been torn loose. Challenger crew radioed g-iii on ground control to advise of the mishap. G-iii returned to ramp.
