FAQs

What about shipping? Penn Yan Aero includes round trip shipping on all Penn Yan Aero overhauled engines from anywhere in the contiguous United States. For Penn Yan Aero overhauled engines outside of the contiguous United States, Penn Yan Aero will pay for shipping from a near point of entry (at Penn Yan Aero's discretion) to Penn Yan Aero and return to a near point of exit (at Penn Yan Aero's discretion). For Lycoming and Continental Factory engines, the customer is responsible for shipping to and from the appropriate Factory. Penn Yan Aero will provide customers with a shipping quote using our trusted and economical venders for consideration.

What's the difference between overhauled and rebuilt? The terms Rebuilt and Overhauled are specific terms with legal definitions. A "rebuilt" engine can only come from the Original Equipment Manufacturer (OEM), in this case, Lycoming or Continental. A “rebuilt” engine includes new and used parts and is entered into the Log Book as a "zero time" engine. An "overhauled" engine can come from any number of sources and may include some new and some overhauled parts or components. Penn Yan Aero overhauls engines to "new limits", or "zero-time" specifications. This is a good thing because it's like getting a rebuilt engine at overhaul price. Overhauled engines do not come with a "zero-time" entry in the logbook.

What is a Remanufactured or Reman engine? These terms used to be synonymous with the term rebuilt. However, the fact is that the term reman or remanufactured is not recognized by the FAA in the Federal Aviation Regulations.

What's the deal with sales tax? Penn Yan Aero is required by New York State law to either collect sales tax or a tax exempt certificate on all transactions with a New York State shipping address. There is no sales tax collected on shipments that are made out of New York State.

What has to be repairable on my core? The price is contingent upon the core engine being a normal run out, as removed, and with a repairable crankcase and crankshaft. (O-300 series also require accessory housing and sump to be repairable and 160HP O-320’s must pass 505). Engines that have had know failures may require special considerations. On Superhawk sales the propeller and propeller spacer cores also have to be repairable.

If I recently purchased new accessories and I send my engine in for OH can you use my accessories and deduct the cost from my OH price? Generally speaking, yes. However, it is important to note that the majority of time we are asked this question, what is perceived as “recently” often turn turns out to be not so recently. Our criteria is 10 hours or less.

If I request special paint for my engine can this be done? Absolutely! We have some very talented people on staff available for custom paint work. Feel free to ask your sales person for details.

Do you provide AOG service? Yes. However, it does depend on many factors. We will do everything we can to offer expedited service in AOG situations. Ask your sales person for more information.

What is the difference between a Static and a Dynamic balance? A static balance is just that…opposing parts are balanced on a scale and the weights are compared against each other. A dynamic balance uses special spin balancing equipment and spin balances the rotating assembly of the engine much like a wheel and tire would be balanced.

What do I send in with my engine? This largely depends on the engine. Typically, we want the complete fuel system, ignition system and starter to be with the engine. Airframe parts like vacuum pumps, alternators, sensors or special fittings and outer engine baffling should be removed prior to shipment. Most inner cylinder baffling can be left in place. Lastly, we do want the logbook with a removal entry.

Why does my low time engine have corrosion? This is a difficult question to answer. Corrosion can have many causes from environmental conditions like humidity to oil condition inside the engine to infrequent usage and even operating temperatures. It is also worth noting that some engine models tend to have more corrosion problems than others.

Why do some parts have corrosion but not others? For starters, these engines are made up of many different materials. Steel parts will rust faster than aluminum will corrode. Magnesium will corrode faster than steel or aluminum given the right conditions. Dependant on the situation, these dissimilar metals can do strange things when given the opportunity. Usage, maintenance and oil can also play a factor.

What does IRAN mean? IRAN is a term that has military origins. It simply stands for Inspect & Repair As Necessary.
