A few weeks ago, I signed up on the FAA's website to receive A.D.s relevant to Ercoupe & C-85 by e-mail. Guess I must have signed up for props, too. I just got a flurry of about 6 Service Bulletins at one time and all relating to props. I've only tried to decipher one so far; it was about vibration dampers attached to crankshafts, but said "except for small engines less than 200 h.p.," so that's not us. Did anyone else get this batch? And if so, can you please distill what they are trying to tell us? (if the rest of them are even relevant to our 'Coupes.) Thanks!
