Narrative:

Aircraft departed ZZZ via paved runway 14 for a local flight to check transponder functions. Contacted approach to receive a transponder code; altimeter setting and to verify altitude reporting. ATC verified all functions indicating properly. Terminated ATC interaction and returned to ZZZ for landing. A training flight had been doing takeoff and landing circuits using grass runway 22 and was continuing in that activity. Light breeze at that time was generally favoring grass runway 22. Typically I would utilize the paved runway 14-32 regardless of crosswind conditions however I elected to join the pattern for the grass runway rather than conflict with the training flight. Entered a left downwind for runway 22 and continued with intention to complete a standard approach to landing. The training aircraft landed ahead of me and cleared the runway. I continued through base to final anticipating a normal touchdown. Aircraft struck the ground resulting in a propeller strike; sudden engine stoppage; and a sliding stop on the runway.there was no damage to the structure or any of the control surface and no injury was sustained as a result of the event. The aircraft was raised by crane; the landing gear extended by normal operation of the landing gear system and then towed to its storage hangar. Having flown this particular aircraft for a full 21 years without incident; it is difficult to assign a clear cause for this operational failure. I conclude that a combination of the decision to land on a grass runway; a choice made only a couple of times over the past 12 years based at ZZZ and the distraction or lack of focus resulting from a quick check flight executed during an extremely hectic day led to a failure to execute my standard routine gump check and the resultant gear-up landing. There were no external factors relating to the environment; other aircraft activity of conditions upon which to place share of blame. This was solely a failure to adhere to a standard routine of practice and simple checklist items during a critical phase of flight. The obvious lesson learned is that there is no place for distraction whether internal or external and that all attention and focus must remain on the task at hand; especially during the most critical phases of flight.
