Just got my prop back from a complete overhaul 30 hours ago (hartzell HC-92Y-8) . Had trusted mechanic torque bolts to 65 ft/lbs and safety wire. The last 2 flights I had noticed a little bit of very fine oil on the very front of the cowl. Several people told me that it is not unusual for a prop to weep a bit. Saturday I was flying home from the Golden West flyin when suddenly there is oil everywhere. Declared an emergency and made it back to the field with no vibration at all. When I got it stopped and my shorts checked, we took the spinner off to find 3 sheared off prop bolt heads dangling around the spinner. WTF? I believe my prop was with in minutes of leaving the airframe. Has anyone had this happen? What are some possible reasons. Prop is on its way back to prop shop today. Yes all new prop bolts at overhaul.
