FAA PMA Solenoids  

 

NEW!  Sky-Tec is proud to introduce by popular demand, Sky-Tec aircraft solenoids!

 

Finally there is a true, high-quality, high-performance FAA CERTIFIED OE/reproduction solenoid available for most popular piston aircraft.   


Never again will you have to use overpriced "new old stock", questionable sources and non-certified tractor supply store products on your certified aircraft!

 

Sky-Tec has once again simply done what makes common sense.  In this case, we simply replicated the best OE solenoids using all new tooling and the highest quality materials to ensure the industry has access to exacting the real thing:  aviation (not automotive) solenoids that fit and wire the same as the originals did.  The terminals are the right size and in the right place and the internals are high quality and built to take the beating that only our smaller piston-engine aircraft can dish out.  We also enhanced inrush capability to ensure maximum performance with Sky-Tec high torque, lightweight starters.

 

And because we're Sky-Tec, you can be assured the price is reasonable and factory support, should you ever need it, is second to none.

 

No one else offers an FAA-certified solenoid at anywhere close to the same quality at anywhere close to the same price.  

 

Available today at all our stocking dealers.  Stock up for your shop TODAY!

SOLENOIDS:

WHAT'S THE POINT?

 

Here's the deal with solenoids:

 

Back in the day, there were mechanical solenoids - in industry, automotive, marine, and of course our adored aviation industry.

 

And while most industries stayed with the times and transitioned to solid state relays, our beloved aircraft remained stuck in time, as they are so often, certified with mechanical solenoids that were once on the aircraft type certificates and never to change.  

 

But let's admit, when they were good, mechanical solenoids were, well, GOOD.  The problem wasn't the solenoid, the problem became the disappearance of reliable sources of suitable mechanical solenoids.  Aircraft manufacturers scrambled finding solenoids overseas (cheap but unreliable) or buying up all new old stock they could get their hands on (making the products very expensive).  But who would be foolish enough to invest the huge sums of time, effort and expense tooling up for a product design that hasn't changed in 50+ years.  Sky-Tec!  That's who!

 

And so Sky-Tec is extremely proud to offer its customers REAL aviation solenoids once again.  

 

Sky-Tec solenoids are built out of the same "good stuff" that the original OE starters were built with in the good old days.  Okay, sure, we took the opportunity to make a few slight improvements (continuous current load capacity and silver tungsten-carbide terminals) but by and large, the goal was simply to get back to the good stuff:  mechanical solenoids that fit like the OE solenoids fit, had the same number and same size of terminals as the OE solenoids and put those terminals in the same location making replacing your aircraft solenoid simple and easy.  

 

And of course, Sky-Tec found a way to make it cost as little as possible.  The investment wasn't cheap, but we seriously think with your help we can sell enough of these to keep the prices well south of one "airplane bill."  So please, by all means, do your part and buy a few TODAY to help that cause!
