Help me use your eligibility search feature.
Here are some eligibility search tips:
- If you do not know your serial number, you can just select your aircraft make and model.
- The model you select must be specific: a 172 is not the same as a 172B.
- Serial numbers must be complete: for example, 15073660 cannot be entered as 73660.
- Hyphens in serial numbers are optional: for example, 28-7325001 and 287325001 are considered equivalent.
- For web browsers with JavaScript enabled, you do not need to click the Submit button when you select a make or model. After typing a serial number, you do need to click the submit button.
- Due to the limitations of our product database, some parts that are eligible for your aircraft may not appear on the returned list of products when your aircraft make, model, or serial number is selected. If you can't find what your looking for, please call or email us.
- Due to the possibility of error in eligibility data and the possibility of non-standard aircraft configurations, McFarlane Aviation, Inc. cannot be responsible for application of our products. The user of the products must verify correct eligibility and function of our products.

What is the difference between a non-dash, a dash one and a dash two aviation oil filter?
Height. Over the years aviation oil filters have gotten shorter to help with installation in tight spaces. The dash two filter by Tempest is the shortest of the certified aviation oil filters on the market.

What is the best way to judge an aviation oil?
Over the years, a number of oils have come and gone. Most new products perform great in one bench test or another, or even in a short-term engine test. But loboratory conditions may not duplicate real world conditions. The best way to judge an oil is to see how it performs in actual service, under real world conditions.
Some of these conditions may include sitting for weeks at a time, starting in less than ideal conditions, and flying on days that your mother would have told you to stay home. Oils with a proven track record, like AeroShell oils, can be counted on to deliver top performance year after year.

How is the D A M product different than other anti-seize products?
D A M anti-seize works on the principle of very small particles of inert dry lubricants imbedding themselves into the open pores of the stainless steel. The dry lubricants lowers friction and prevent corrosive adhesion of the two stainless steel surfaces. The dry lubricants prevent combustion by products from actually gripping the stainless steel. Other products rely on powdered metal such as copper or nickel in a mix of greases and graphite. The powdered metals themselves are often corrosive to the stainless steel at high temperatures and actually create adhesion by microscopic corrosive residue. The old failed theory is that the metal powder flakes will separate from each other and allow disassembly. This does not work at high temperatures and with stainless steel. Any graphite in the compound (graphite is required for MIL SPEC anti-seize compounds) sets up a severe galvanic corrosion action with the stainless steel and the powdered metals that produces corrosive by products that swell and lock the joint while attacking the grain structure of the stainless steel. This corrosive action is accelerated at high temperatures and contact with combustion by products.

Will the synthetic portion of semi-synthetic AeroShell Oil W 15W-50 harm an aircraft engine?
A number of pilots have asked this question. The answer is a definite no. When Shell first started evaluating multigrade aviation piston-engine oils over 25 years ago, testing proved that multigrades formulated only with mineral base oils did not have adequate base oil viscosity (thickness) to properly lubricate all high load points in the engine. Then we tested and flight evaluated a formulation made with all-synthetic base oils.
This formulation had excellent antiwear characteristics in all tests run. However, in the flight evaluations, some engines would reach 600 to 900 hours, then lose oil consumption control and/or compression. When the engines were disassembled, we found that the piston rings were covered with a gray tacky substance that was primarily made up of the lead by-products of combustion (from the use of leaded aviation gasoline).
Although synthetics are excellent lubricants with good high temperature stability and very good low temperature flow characteristics, they are relatively poor solvents.
In an aircraft engine, the lead by-products of combustion must be dissolved by the base oil so they can be carried away from the ring belt area and removed from the engine when the oil is changed. Anticorrosion, antiwear AeroShell Oil W 15W-50 is formulated with 50% synthetic base oils to give it the excellent low temperature flow needed for quick lubrication during cold starting.
The synthetic base oils, along with the unique antiwear additive system, give it antiwear protection unequaled by any other product on the market. In addition, its mineral base oils provide lead absorbency to guard against ring sticking and excessive sludge. The bottom line: The synthetic component of AeroShell Oil W 15W-50 will not harm your engine. Instead, it gives you the best of both oils.

Is the aircraft magneto connected to the rest of the electrical system?
No, the aircraft magneto ignition system is self-contained and independent from the aircraft electrical system. In the event of an electrical failure, the mechanical aircraft magneto will continue to provide spark to the engine.

What are the benefits associated with Marsh Brothers' product?
Longer life-time, grease-free operation, does not support corrosion, decrease in weight, self lubricates.
|
Do Tempest oil filters use a magnet?
Yes, all Tempest aviation oil filters use a magnet. This give us an extra layer of defense to help filter out smaller micron particles that may get past the filtration media.

If my aircraft engine has a Supplemental Type Certiļ¬cate for automotive gasoline, can I break in?
No. Most of the metallurgy in the valve train of aircraft engines was designed to be operated on leaded fuels. Even 80/87 engines were designed for fuels with 0.5 gram per gallon lead. Experience has shown that the lead level in aviation gasoline is especially critical during break-in. So, if you’re breaking in a new or an overhauled engine, make sure you use a leaded 80/87 or 100/130 low lead aviation gasoline for at least the first 50 hours of operation. Some fuel suppliers sell an unleaded 80/87, so make sure you're getting leaded gasoline for breaking in your engine.

Do I have to fill out a form 337?
No, PROP GUARD is an FAA-PMA/STC product, but the STC specifically states that a form 337 is not required. It does require an A&P mechanic endorsement for return to service.
|
How do I keep contaminants out of my fuel system?
The fuel selector valve works in unscreened fuel. Contaminated fuel can cause selector valve seal damage. When fueling from possibly contaminated fuel sources McFarlane recommends the use of a fuel filter, such as Mr. Funnel or another filtering device, to reduce trash in the fuel system.

All other anti-seize I have used are thick. How can this work when it is so thin?
The D A M high temperature anti-seize formula is based on inert high temperature dry lubricants suspended in a naptha carrier with a few other low viscosity additives. The thick grease base in other anti-seize products on the market burn and char at exhaust temperatures leaving sticky hard deposits that actually contribute to the lock-up of exhaust joints. The D A M product carrier evaporates leaving only a film of dry lubricants in the joints that penetrates the pores of the stainless steel.

How do I determine my sales tax exemption status?
State regulations require sales tax to be collected unless certain exemption forms or information is received. Sales tax is calculated based on the state and jurisdiction shipped to. Some states have specific general aviation tax exemptions and require shipping charges to be included in sales tax calculation. Sales Tax Exemption Wizard

Why is PROP GUARD glossy instead of flat? A satin or flat finish would match the flat black on the back of the propeller.
A flat finish material was tried but the manufacturing process to get a flat finish reduced the strength of the product. The glossy finish has little effect on light reflection in flight.
|
How does the D A M product work to loosen locked slip joints?
D A M’s light petroleum carrier uses capillary action to penetrate the joint and carry the small particles of dry lubricant into the joint. By mixing D A M and other solvents such as acetone, MEK or other solvents the viscosity is lowered more yet and the mixture will penetrate small spaces more effectively to loosen corrosion and combustion by products while lubricating the joint.
|
Why does a small can of the D A M product cost so much?
The high temperature inert dry lubricants are expensive to produce and refine. Since it only takes a thin film to be effective it is more economical than other anti-seize compounds. A can goes much further.
