I use understand your concern about the wing AD but I think you need to get some basic info. Some of which impacts the spar AD.........
What year is this airframe?
What is the AFTT?
When was is last flown?
Why was it parked?
Are all the log available?
Do understand and have a list of all the outstanding service bulletins and ADs that need to be incorporated?
When was the engine last majored?
Have you borescoped the cylinders?
What do the engine logs indicate or tell you?
Do you have an A&P in hand who is willing to work with you?
Do you have the necessary shop space?
Do you have the necessary tooling on hand?
Do you really have the skills to pull this off?
Do you have the time to invest to get this project completed?
Do you realize that almost every system on this plane will need to be gone through and most likely require a rebuild or replacement?
Have you and or your A&P inspected the airframe for corrosion?
Do you really have a handle on the cost of replacement parts in today’s market?
Have you done a balance sheet for the project?
Do you have the financial resources?
Are you married, and if yes, is she OK with what you’re about to undertake?
The above is just a short list. Yes any airplane can be brought back from the dead given enough time, money and determination. It’s tough to separate the emotion & passion from reality. Not trying to rain on your parade but just want you to fully understand the complexity of the task you are contemplating.
