Pac Sky = Your answer for legacy T56 series 3.0 engine parts. Aftermarket manufacturing for platforms that still matter.
What Sets Us Apart
We’re not the OEM—and we respect them deeply—but we exist because they do. We’re aftermarket disruptors, competing with a legacy giant every single day.
They crafted timeless designs. We’ve spent our careers matching their excellence—if not surpassing it. We’re the scrappy little sibling, always close behind.
We are proud to support old platforms. Sustaining propulsion dominance across decades-old fleets is what we do. For us, “legacy” means more than age—it means responsibility, readiness, and respect for the platforms that still matter.
The Spirit of a Disruptor
We are a non-traditional defense manufacturer in the best way possible:
- We’re fast, persistent, and ready to pivot.
- We take initiative and manage risk with a clear vision.
- We stay creative, finding solutions where others say “no bid.”
- We understand the propulsion industrial base—and we see the white space others
overlook.
Disruption isn’t noise—it’s meaningful action. And that’s how we solve real problems in today’s Defense Industrial Base.
Many Parts in Stock
We don’t wait for a need—we anticipate it.
We stock parts proactively, even without a guaranteed PO, because we know when the call comes, it won’t come with time to spare. We’ve built our forecasting discipline over decades. The result? Real inventory, ready to ship.
A majority of our parts are backed by rigorous approvals from the Department of Defense and the FAA. That’s more than support—it’s reliability in action.
We put our manufacturing expertise to work for you.
In-House Manufacturing
We build it here. In Los Angeles. Down the road from where aircraft first took to the skies.
We machine, assemble, inspect, and document it ourselves. No excuses, no finger-pointing—just accountability and craftsmanship.
All within a city better known for movies than machines. We’re an outlier, and we like it that way.
Engineering Depth
When the OEM support is gone, we lean in.
Our engineering team thrives on the complexity of legacy platforms—bringing back to life parts others abandon. Materials, performance, tolerance stackups—we restore the full design language, and we make it producible again.
Global Support / Combat-Ready Reach
Combat-ready air power depends on parts you can trust—whether the aircraft is down the road or across the world.
We support domestic operators and allied forces globally, with full export compliance and an understanding of what “mission-critical” really means. Our parts sustain readiness in environments where failure is not an option.
Quality Assurance
Quality isn’t an afterthought—it’s the foundation.
It lives in our culture. It’s on our walls. It’s in the charts we track and the approvals we maintain. Our team knows that every job, no matter how routine, can affect a mission outcome. We treat every step accordingly.
