RV-8 with AEIO-360 (200 hp) with a Hoffman 2 blade composite CS prop. Last year, the spinner bulkhead failed, causing the spinner to wobble and gouge the prop, requiring it to be removed and remanufactured. Got the prop back in June.
Now, 55 hours later, the new spinner bulkhead has gouged in to two pieces - fortunately, I found it as soon as it happened, preventing serious damage to my prop. I don't think I am doing anything unusual inflight. Prop full forward for takeoff, reduced to 2500 rpm for climb and aerobatics, 2400 for cruise. There are no rpm limits published in my prop manual.
Does anyone have any idea why this would happen?
