I am a new owner (1 year in) of a 1970 PA-28 140/160. I have been trying to update and stay on top of maintenance issues. I have a learned a lot about the plane and truly love the way she flies and does so affordable. Does anyone know the best way to obtain a parts catolog for my airplane? Getting a part number has been a challenge at times. My A&P has been helpful but I feel like a pain when I call him often. Any help would be appreciated.
