## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ON JUNE 10, 2024 AT 2100 MDT, A BEECH D55 BARON, DEPARTED OFF THE RIGHT SIDE OF RUNWAY 17R AT THE COLORADO SPRINGS MUNICIPAL AIRPORT (KCOS) APPROXIMATELY 2260 FEET FROM THE APPROACH END OF THE RUNWAY. WEATHER AT THE TIME OF INCIDENT WAS VMC CONDITIONS WITH CALM WINDS. THE RIGHT TIRE WAS PUNCTURED WITH AN UNKNOWN OBJECT THAT PENETRATED BOTH THE TIRE AND TUBE. WHEN THE PIC APPLIED BRAKES, THE AIRCRAFT BEGAN TO PULL TO THE RIGHT SIDE OF THE RUNWAY. THE PIC RELEASED BRAKE PRESSURE AND THE AIRCRAFT CONTINUED TO PULL TO THE RIGHT. THE AIRCRAFT BEGAN TO VIBRATE OR WOBBLE, AS DESCRIBED BY THE PILOTS AND THE PIC ADDED LEFT RUDDER AND LEFT BRAKE TO CORRECT THE TRACK BACK TO CENTERLINE, BUT THIS ACTION WAS INEFFECTIVE.  THE VIBRATION FROM TIRE OSCILLATION INDUCED AN INADVERTENT RELEASE OF THE RIGHT MAIN LANDING GEAR OVER CENTER PIVOT, WHICH RESULTED IN THE COLLAPSE OF THE RIGHT MAIN LANDING GEAR. THE RIGHT PROPELLER CONTACTED THE GROUND AND THEN THE ENGINE NACELLE AND WING. THE INCREASED DRAG PULLED THE AIRCRAFT FURTHER TO THE RIGHT AND OFF THE RUNWAY INTO THE GRASS. TWO PEOPLE ABOARD SHUT DOWN THE AIRCRAFT AND INITIATED AN EVACUATION WITHOUT INJURIES.
