Hi everyone! I'm looking to buy a Cessna 150. I have found one that I am interested in. I contacted the owner and he is a mechanic himself. He purchased the airplane from a friend. The airplane had not flown for 5-6 years. He ferried it home and did a annual and got all the instrument inspections done one the airplane. The airplane has been stored in a cool dry hangar the whole time. I guess my question is, is there anything I need to be concerned about after a airplane has sat for that long? Dried out gaskets or seals gone bad? I do plan to send a mechanic out to do a pre-buy. I just being cautious, I am a first time buyer.
