Aviation parts sourcing · AOG support

Aviation parts, sourced and delivered.

Specialists in Sikorsky S-61, S-64, UH-60 and CH-53, and equipped to source across the wider fleet. Send us a part number and we will tell you what we can get, what condition it is in, and how fast.

Who We Are

Specialized in Sikorsky. Sourcing across the fleet.

We supply parts to aircraft operators, aerial firefighting outfits, MRO facilities and repair stations across the United States.

The aircraft we support have one thing in common: the factory stopped stocking them. Once the OEMs moved away from holding inventory, lead times on new production stretched out to a year or more, and the surplus pool has been getting thinner every season since.

That is the problem we solve. We keep the parts moving so an overhaul is not sitting on a shelf waiting for one line item, and so a machine is not down through the middle of fire season.

Sikorsky is where we go deepest, and it is deliberate. Knowing a handful of airframes properly beats knowing twenty of them badly. It is the difference between a part that fits and a part that almost fits, and on these machines that difference matters.

That focus is our specialty, not our limit. Operators rarely run one type, so we take requirements across the wider fleet as well, rotary and fixed wing alike. Send it over and we will work it the same way.

We are based in Sparks, Nevada. You deal directly with the people doing the sourcing, so there is no ticket number and no call queue between you and an answer.

Our Capabilities

What we handle.

One hard line item or a full overhaul kit. Either way, same treatment.

Parts Sourcing

Rotables and expendables for legacy and in-service fleets. The jobs we take on are usually the ones that came back empty somewhere else.

AOG Support

AOG requirements get quoted the day they land. Price, condition and lead time in the first reply so you can make the call without chasing us for details.

Exchange & Core Pool

An overhauled unit ships out, your core comes back to us. Keeps an expensive rotable on your shelf instead of stuck in a repair queue when you need it.

Overhaul & Preload Kits

The wear items for a gearbox or component overhaul, put together as one kit. One quote, one shipment, instead of forty separate chases.

Manufacturing Coordination

When there is nothing left to buy, we get it made. Established shops, and quantity pooled across operators so the unit price comes down for everyone.

Documentation & Trace

Material arrives with the paperwork your inspector is going to ask for. FAA 8130-3, EASA Form 1, OEM certs or a certificate of conformance.

Where We Specialize

Four airframes we know inside out.

We do not sell aircraft and we do not fly missions. We supply the parts that keep them working. These four are where our depth is, and they are not the only ones we source.

Sikorsky S-61N Sea King helicopter in search and rescue configuration SIKORSKY

S-61 Sea King

S-61 / SH-3 · MEDIUM LIFT

Still working hard in utility, offshore, construction and firefighting fleets decades after the line closed. Support is out there, but the surplus pool keeps thinning, particularly around the gearboxes and the fuel system.

GEARBOXESFUEL SYSTEMROTABLESAIRFRAME
Sikorsky S-64 Skycrane / CH-54 Tarhe heavy-lift helicopter SIKORSKY

S-64 Skycrane

S-64 / CH-54 TARHE · HEAVY LIFT

Heavy lift and aerial firefighting. Thin OEM support and a shrinking surplus market mean planning ahead beats scrambling, which is why we build kits for these gearboxes rather than chase them one part at a time.

Sikorsky UH-60 / S-70 Black Hawk helicopter SIKORSKY

UH-60 Black Hawk

UH-60 / S-70 · MEDIUM LIFT

A big fleet, getting older, and moving into civil, utility and firefighting work. Demand for wear items is climbing faster than the supply behind it. We are putting depth into this platform now rather than later.

CH-53 Sea Stallion

CH-53 · HEAVY LIFT

Shares a good deal with the Skycrane across the drivetrain and rotor system, which gives us somewhere else to look when Skycrane stock runs out. United States customers only.

Beyond Sikorsky

We source across the wider fleet.

Sikorsky is our specialty, not the boundary of what we handle. Operators rarely run a single type, and neither do the repair stations that support them. We take requirements for Boeing, Bell, Airbus, Leonardo and fixed-wing platforms as well, and we work them the same way as everything else: a straight answer on availability, condition and lead time, or a straight answer that we cannot help.

Component Support

Components and overhaul support.

The parts that get replaced at scheduled overhaul, and the awkward ones holding an aircraft on the ground.

Helicopter rotable components, bearings and seals

Components & Rotables

Bearings, seals, gearbox components, generators, valves, latches and structural hardware. New, new surplus, overhauled or serviceable, with the condition confirmed before you commit.

Helicopter gearbox overhaul and component maintenance

Overhaul & Exchange

Overhaul kits put together as a set, and exchange arrangements that keep an expensive rotable available to you instead of tied up in a shop.

How We Work

Straight answers, and the part shows up.

Most complaints we hear about suppliers come down to three things: no reply, a condition that was not what was promised, and paperwork that fails at receiving. We work to not be that supplier.

01

You get an answer

Send a requirement and you hear back the same business day. If we can supply it, you get price, condition and lead time. If we cannot, we say so rather than leave you waiting on a quote that is never coming.

02

Condition is what we said

New, overhauled, repaired, serviceable or as removed. Whatever is written on the quote is what arrives on your dock. We would rather lose the order than talk up a unit and have it come back.

03

Paperwork sorted first

We confirm what your inspector needs before the part moves, not after it has been rejected. Anything that controls flight is supplied fully certified, or we pass on the job.

Quality & Compliance

Traceable and documented.

What arrives on your dock matches what was quoted, with the paperwork to back it up.

  • Condition and trace on every quoteYou know exactly what is coming before you order.
  • Flight-critical parts supplied certifiedAnything that controls flight comes fully documented, or we pass on the job.
  • Serialized material trackedTag, overhaul facility and certification date supplied with the unit.
  • United States domestic supplyInternational inquiries are reviewed case by case under applicable export licensing.

Export Control

Certain rotary-wing components are controlled defense articles under the ITAR or the EAR. GCS Aerospace screens end use and destination on every inquiry, and does not ship controlled material internationally without the required license and a signed end-user statement.

Send us the part number.

Include the quantity, the condition you need and whether it is AOG. The more detail in the first message, the faster we can come back with something useful.
