When should I replace my Slick magneto?

We strongly recommend following the manufacturers’ recommendations to pull mags at 500 hours time in service to replace them (Champion/Slick mags) or (Continental/Bendix mags) open them up, inspect and replace components as necessary (IRAN—more about IRAN later).

What are Slick magnetos?

A Slick magneto is a specific type of aircraft magneto manufactured by Champion Aerospace. Almost every Slick magneto is sold new, as overhauls to this kind of aircraft magneto are rare. Quality Aircraft Accessories is the only Slick Magneto Factory Authorized repair center.

What are the types of magneto?

There are various types and brands of aircraft magnetos and choosing the right one for your aircraft application is important. The predominant aircraft magneto types are Slick Magnetos, Bendix dual magnetos, and Bendix single magnetos.

How much does it cost to rebuild a magneto?

500 hour inspections to this magneto typically range from $300-$400 while overhauls are typically in the $500 to $600 price range. The 1200 has many parts, few of which may be reinstalled after being removed, and therefore must be replaced with new parts.

Which part should be replace on magneto overhaul?

The parts in question are the coil, impulse coupling assembly, block and gear. During the Factory Overhaul process all of these items are replaced 100% of the time with new parts from Champion.

How long do slick mags last?

Slick magnetos, model no. 4301 , approaching 500 hours, ( Have to check log if 500 since new, or 500 since last inspection ) installed on Continental O 200 , flies 100 hours a year. Motor runs fine , no problems, 1400 smoh .

How do Slick magnetos work?

The function of the aviation piston engine ignition system is to provide an electrical spark to ignite the fuel/air mixture in the engine cylinders. Magnetos are engine-driven self-contained units that supply electrical current without using an external source of current. …

How much does a slick magneto weigh?

3-3/4 lbs.
These lightweight aircraft magnetos are being used by many new equipment manufacturers. Weigh only 3-3/4 lbs. compared to 6-1/4 lbs. for typical old style magnetos.

What are the 3 circuit of a magneto?

The magneto system is generally divided into three distinct circuits that include magnetic, primary electrical circuit and secondary electrical circuits.

Does a magneto produce AC or DC?

A magneto is an electrical generator that uses permanent magnets to produce periodic pulses of alternating current. Unlike a dynamo, a magneto does not contain a commutator to produce direct current.

What causes a magneto to fail?

The voltage generated across magneto coils is quite high, in the order of 20,000 volt if no spark plugs are in place. The gap will widen as the wire ends melt further apart and soon the adjacent turns will be affected so the coil will eventually fail. …

What’s the difference between Bendix and slick magnetos?

Slick magnetos, now manufactured by Champion, are smaller than comparable Bendix mags; however, they are significantly less expensive. Due to price, some models are considered throwaway—after 500 hours in service, the cost of buying a rebuilt exchange mag is often the same as opening up and repairing the existing mag.

Is it economical to overhaul a slick Magneto?

In our opinion Slick Magnetos are NOT economical to overhaul. Champion Aerospace has a list of parts which MUST be changed to qualify as OVERHAULED. The cost of these parts far exceed the cost of an exchange (NEW) magneto. The following are Manditory Parts that must be changed to qualify as Overhaul.

What kind of magnetos are used on Lycoming Engines?

The D-2000/D-3000 series are “dual magnetos”—two magnetos driven via a single shaft. They are only used on Lycoming engines and Continental no longer supports them. Parts availability is reportedly still good. Slick magnetos, now manufactured by Champion, are smaller than comparable Bendix mags; however, they are significantly less expensive.

What happens if a mag on a Magneto goes bad?

If the engine smooths out on one mag, but continues to run rough on the other—shut off the mag that is causing the engine to run rough. A failure within a mag that causes the engine to misfire is potentially serious. Misfiring can lead to detonation and catastrophic failure of the engine.
