Our RV-6 is 10 yrs old with 350 hours on it. We were wondering about Hartzell recomending OH at 6 years and knowing ours was low time and always hangered we figured all good. Hartzell says the time limit is there for corrosion mainly so we knew we should get an OH some time but wasn't sure when. Well yesterday, we noticed a fine speckling on the nose area behind the spinner after flying for a couple hours. We removed the spinner and top cowl to find it was grease leaking from the hub joint close to the blade seal. It appears the grease leaked and was slung against the backplate and slipped between the spinner/backplate and then was slung against the cowling in little specs. Now that we see this...we remember seeing very tiny specs on the canopy but couldn't determine what it was or where it was comming from. Now we know. We are surly glad is isn't oil and didn't coat out canopy in flight like some stories we have read about. I'm assuming we will now have the prop Overhauled!! I just thought I'd post this information for others to see and maybe learn from. We checked Hartzells website and found this hub isn't the model that cracks! So we are thankful of that as well. Any commets or sharing of experiances would be appreaciated.
