Got a question I hope you all can help with. I'm looking at an aircraft that has a T.T. of 1220 hours and 240 since an IRAN. I've done some research on Inspect, Repair as Necessary and it's not an overhaul. If I'm looking at the overall condition of the engine, does the IRAN 240 hours ago have any effect on the price? As near as I can tell the engine will still reach TBO in 780 hours.

The prop was overhauled 240 hours ago, I'm wondering if there was a prop strike. Anyway, does the IRAN influence the overall value of the plane or do I look at it as a 1220 hour O-360.

I would assume that means it had a prop strike. The IRAN entry likely means it had the appropriate and required prop strike inspection but no other work. The IRAN entry has no impact on the SMOH numbers. There should be no impact on the value of the aircraft unless you feel that having a maintenance entry devalues the aircraft. I don't buy airplanes to sell them, so not sure I really understand that point of view anyway...from the standpoint of the value of the airplane to me as a buyer it indicates that needed repairs were made and I would take that overall as a positive.

Thank you. That was what I was expecting to hear. I'm new to airplane buying and there are a bunch of little things that can add up to big things Thanks for taking the time and helping.

Much appreciated,

I thought IRAN halted all inspections when we pulled out of the nuclear agreement...no?

IRAN in the military actually meant "Paint and Return."

It would kind of depend on who was doing the inspection. Some people are more observant and critical. Look for an inspector that is OCD for those types of inspections.

Does the owner have a detailed list of what parts were inspected and what their condition was to warrant or not warrant repair/replace?
If not, it's useless.
Same as a logbook entry for overhaul with no paperwork... useless.

The owner has a detailed list of everything that was replaced. It was extensive. There was an insurance company involved in the prop strike and they wouldn't pay for a major overhaul and It was done by a reputable company. Apparently it was a few parts short of being a major overhaul.

That is standard. Insurance companies do not pay for regular wear items, including engine overhauls. Since the opening of the engine is a large part of the cost of an overhaul, it makes sense as an owner to pay the additional costs to get an overhaul done if the engine is past half of its hourly life or if the last overhaul was a long time ago. Basically in that case you get an overhaul for half price or less. But if it is a low time engine, even if the overhaul is a bit old in calendar time, the IRAN for a prop strike can be a useful inspection that solidifies your confidence in the engine condition.

Don't be fooled by the, 'few parts short' of being a major overhaul though. There is a difference between saying that a part is airworthy (not cracked, no worn areas of concern, not bent, etc.) and certifying it as being dimensionally suitable to qualify for re-installation as specfified in an overhaul manual. I would be totally comfortable with the engine you are looking at based on your description of the situation. But unless the crank and the cam and the lifters and the rocker arms and the pistons and the cylinders were measured and within MOH tolerances, it isn't particularly close to an overhaul. But you likely got all new gaskets and bearings, which is good. And you know stuff isn't bent or cracked, which is good.

I'm with Troy on this one. While the IRAN does nothing to change the TSO for the engine, if it was done by a reputable shop who knows what they are doing, it would add to my comfort level in purchasing the airplane. Definitely NOT a black mark!

I purchased an airplane whose engine had an unusual prop-strike. The stationary prop (airplane was died down on grass) got run into by an FBO employee with a mower. The roll bar hit the prop hard enough to bend it. Fortunately for the owner, a pilot acquaintance of his saw the whole thing, and gave him a call. The FBO's insurance paid for a new prop (bent way beyond repairable limits), and to have the engine IRAN'ed by Mattituck (back when that was a good thing). The engine was checked over pretty thoroughly, and had all the seals replaced as part of that work. That inspection only added to my confidence in the airplane's mid-time engine.

Your post lacks details. What was replaced during the IRAN? Was the bottom end essentially rebuilt? Knowing your cam and lifters are new or in excellent shape would interest me as a buyer. There are a ton of parts on the overhaul list, items like overhauling your mags, new harness, and through bolts.The internal components that wear are important to me....if I was buying.
