Analysis narrative
The pilot reported that while on the downwind leg of the traffic pattern he became distracted by a rain squall which resulted in his failure to extend the landing gear, and the airplane subsequently landed gear-up. The airplane sustained substantial damage to the fuselage during the gear-up landing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
