The Learjet 55, N600C, was substantially damaged when it was involved in an accident Greater Rochester International Airport (ROC/KROC), Rochester, New York. The occupants were not injured.
The copilot described the flight as uneventful to FAA inspectors and reported that the airplane landed in the touchdown zone "firmly, but not exceptionally so." He did not realize that the airplane was damaged until after landing, when he saw fuel leaking from the airplane after deplaning.
The pilot described a "stable approach" and stated that the landing was "firm," but that after landing, the crew could "tell something was wrong as the aircraft was leaning to the left." Once they deplaned, they found the left strut assembly collapsed, with damage to the landing gear attach point, damage to the left wing, and damage to the fuel tank.

During the approach, a passenger stated that she could hear altitudes called out, which sounded automated, and just prior to touchdown, she heard "too fast, too fast, which sounded like a person." She stated that the airplane "slammed" onto the runway, the oxygen masks deployed, compartments inside the airplane opened. The airplane bounced, and the second landing was "very bumpy." She said the pilot shouted an expletive after landing, was "apologizing profusely" as they deplaned.

A review of airport surveillance video revealed that the airplane touched down in the area of the displaced threshold prior to the landing runway, bounced, and continued about 270 feet before it touched down and rolled out on the runway.

Examination of photographs revealed skid marks, ground scars, and fractured and broken parts associated with the left main landing gear wheel assembly, the retaining system for its brakes, a fractured piece from the strut cylinder and a fractured piece of its snap ring (retainer).

The initial ground scar and skid marks consistent with the dimensions of the left main landing gear tires, began in the displaced threshold about 110 feet prior to the landing surface. The fractured parts were scattered over and beyond the ground scars and tire markings.
