Question --TO explain more since you said you didnt fully understand. I just figured I would update the engines to a more current powerplant. Is that a good idea. Of course a jet that old will be looked at very carefully in and out. I just like that Lear24 and 23. Always wanted one when I was a kid in the 70's. Who does that type of work... Lear, Garrett, GE, a local Aviation mechanic.-----------------------

Question -
I would like to buy a Lear 24 but since the aircraft is built in the late 60's or early 70's, would be OK to get another 2005 GE engine? Or is this a waste of money and time. Good idea or not?
Answer -
I do not fully understand your question but will attempt to give you some input. The age of an aircraft is not measured in real time only. Total time is only one parameter because the location of the aircraft must be considered. Was it operated and stored inland or on coastal areas prone to salt air corrosion. Stress corrosion is brought about by the total time and operating conditions like hard landings and flying in severe turbulence. When buying older aircraft beware of very clean aircraft that may give a false impression of its condition. I once inspected a Cessna 182 that is known for developing loose rivets in the nose wheel mounting on the firewall. The condition was not apparent in this aircraft but I noticed rivets galling on the belly between the main gear. Checking the baggage area revealed a wet bucket and cleaning materials. The owner flew in early in the day and cleaned all the tell tales signs of those loose rivets. Lucky for me he missed a few places between the gear and I was able to determine this aircrafts true condition. So buying old an aircraft requires a thorough inspection. Ad's and service bulletins must be checked even if they have been said to have been complied with.
When dealing with engine retrofits that requires looking to any STC's that may be required and best dealt with by people in that trade. Avantext will have this information should you want to research it yourself.
Another point to consider when buying an aircraft and that is the insurance cost for the make and model. I would suggest contacting an insurance agent to discuss the cost of insurance for various different models of aircraft you intend to buy. This is all part of budgeting the cost of owning a specific aircraft as well as the aircraft and engine maintenance cost.
Answer If your asking about updating the engines on that old aircraft then you should be contacting companies that do engine updates for Lears. Yahoo list many companies that do that type of work. They will be able to answer all your questions including the cost. Since I have never done any updates on a Lear I can't be of much help Those companies will know what structural changes might be needed to change engines. Bombardier now builds Lears they may steer you in the right direction.
