Aircraft
This was a return flight to the plane's base after a work related training flight. Our first approach to land runway 24 resulted in a go-around due to undesirable lineup on short final. On our second approach winds were from 300 degrees at 10 knots; gusting 25 knots. Tower notified us of wind shear experienced by the aircraft that landed before us. Standard procedural aircraft checks and proper configurations were made prior to landing with no abnormalities present. The landing was acceptable given the conditions. However; upon landing both pilots heard something come from the right side of the aircraft. This was at first thought to be a flat tire. However; handling tendencies were not consistent with a flat. Shortly after landing tower alerted us that possible landing gear problems were observed. The plane continued to handle fine. It wasn't until rolling further down the runway that the plane sank to the right and the right prop struck the ground. At this point both pilots shut down and secured the aircraft and made sure no one was injured.It seems a bolt that served as part of the gear broke. Preflight inspections did not reveal anything out of the ordinary as everything appeared intact and consistent with multiple prior preflight inspections. I am unsure at this point what caused the gear to collapse. My only assumption is that the bolt in question failed as a result [of aging].
PA23 pilot reported the right main landing gear collapsed on landing roll resulting in a prop strike.
