Narrative:

Entered pattern for runway 29 in hazy conditions was unable to make radio contact due to radio failure. Was starting checklist when I located another VFR aircraft in pattern. I must have lost my place in checklist which is a completion type that moves from right to left around cockpit. Poor light conditions at checklist clip contributed as did failure of gear horn. Damage was confined to the propeller and lower cowl. Cause of horn failure and radio failure not yet determined. Inspection of main crank shaft runout not yet completed. Gear output shaft and propeller spline shaft are ok. I believe the checklist was not the best one I could have used but I am not sure what would have been a better way to make it. The cockpit is simple to an extreme, simpler than my small aircraft.
