Specifying Gas Springs for Aerospace Use: The Honest Starting Point
Gas springs for aerospace use split into two very different categories, and almost everything else about the specification depends on which one applies. Certified flight-critical hardware requires AS9100 production, NADCAP special process approval, DO-160 environmental qualification, and full material traceability through the airframe manufacturer’s approval chain. Everything else — ground support equipment, experimental and light-sport aircraft, UAV airframes, hangar and maintenance equipment — is territory where a well-engineered, non-certified gas spring is a legitimate and common choice. Knowing which category an application actually falls into settles most of the confusion up front.
We hear a version of the same question from engineers fairly often: a tow-bar builder, an experimental aircraft owner fabricating a canopy strut, or a UAV airframe designer googles “aerospace gas spring” and finds page after page claiming aerospace qualification without ever explaining what that actually requires or whether it applies to their project. At Newtone Gas Springs, we manufacture in Turkey and export to more than 60 countries, and this page exists to give a straight answer to that confusion rather than add another vague claim to the pile.
Who this page is for: ground support equipment builders, experimental and light-sport aircraft owners and kit manufacturers, UAV and drone airframe designers, and MRO or hangar equipment builders trying to work out what “aerospace-suitable” actually means for their specific application.
Gas Springs for Aerospace Use: Certified vs. Non-Certified
The single most useful thing this page can tell you is where the line actually sits, because most suppliers blur it. Certified flight-critical gas springs are built and documented under AS9100 (the aerospace-specific extension of ISO 9001, adding risk management, configuration control, and first article inspection), qualified against RTCA DO-160 environmental requirements (vibration, altitude, temperature cycling, EMI), manufactured through NADCAP-approved special processes for plating and heat treatment, and traceable through the airframe manufacturer’s own FAA or EASA airworthiness approval chain. That standard exists for primary flight control surfaces, safety-of-flight structure, and cabin systems on Part 23 and Part 25 type-certificated aircraft.
Outside that category, a large and legitimate market runs on well-engineered gas springs without the certification stack: ground support equipment like tow bars, maintenance stands, and ground power carts; experimental and amateur-built aircraft, where the builder or kit manufacturer — not a type-certification authority — accepts the component; light-sport aircraft under LSA consensus standards; UAV and drone airframes outside manned-aircraft certification requirements; and hangar, MRO, and simulator equipment. This is where Newtone fits, and where we’re straightforward about it: we hold ISO 9001, ISO 14001, and ISO 45001 certification, but not AS9100 or NADCAP, and we don’t perform DO-160 qualification testing. If a program genuinely needs certified flight-critical hardware, that’s a different supplier conversation, and we’d rather point that out than let a vague claim stand in for it.
Why Rod Diameter Matters More Here Than Almost Anywhere Else
Weight is the design constraint that separates aerospace-adjacent applications from most industrial ones, and the gas spring’s own weight comes down to a simple relationship between force, pressure, and rod diameter.
Fundamental Force Law
F = ΔP × A
Rod Cross-Sectional Area
A = π × d² ÷ 4
Take a target force of 200 N (45 lbf) and compare two rod diameters. At 6 mm (0.24 in):
A = π × 6² ÷ 4 = 28.3 mm² (0.044 in²)
ΔP = 200 ÷ 28.3 ≈ 7.1 MPa (1,030 psi)
And at 10 mm (0.39 in):
A = π × 10² ÷ 4 = 78.5 mm² (0.122 in²)
ΔP = 200 ÷ 78.5 ≈ 2.6 MPa (370 psi)
Same force, very different internal pressure — and the smaller rod, thinner tube, and lighter fittings that go with it can add up to meaningful weight savings on an airframe-adjacent build, provided the seal system is rated for the higher pressure. We saw this trade-off directly with an experimental aircraft builder specifying a canopy strut for a homebuilt design: their initial dimensions assumed a rod diameter that would have added unnecessary weight to hit their target hold-open force. Running the actual hinge geometry and center-of-gravity numbers showed a smaller rod at higher fill pressure reached the same force at a noticeably lower weight, and we corrected the spec before the first article was cut.
Where the panel opens and closes repeatedly — an access hatch or overhead bin rather than a static-hold canopy — the force progression ratio also matters for how the motion feels: K = P2 ÷ P1, typically 1.2–1.4 for a smooth, rising-resistance feel toward the closed position rather than an abrupt one.
Temperature Range and Material Choice for Aerospace-Adjacent Use
Newtone’s standard operating range of −40°C to +100°C (−40°F to +212°F) covers the great majority of ground support, experimental aircraft, and hangar equipment conditions, including cold-weather ramp operations and hot climate storage. It is not the same thing as DO-160 qualification, which tests specific combinations of altitude, rapid decompression, vibration profile, and EMI that go beyond a standard temperature and cycle rating — worth flagging honestly rather than letting the number imply more than it covers.
Material selection follows exposure, same as any other application: HNBR seals are standard for UV and ozone resistance on anything left outdoors, and stainless steel is worth reviewing for coastal-based ground support equipment or salt-air hangar environments, while a black-nitrided rod is generally sufficient for protected interior or hangar-stored equipment.
Specification Quick-Reference by Application
| Application | Typical Weight | Recommended Force | Spring Count | Notes |
|---|---|---|---|---|
| GSE tow bar / equipment cover | 3–8 kg (7–18 lb) | 80–150 N (18–34 lbf) | 1 | Outdoor ramp exposure — review stainless |
| Experimental/LSA canopy strut | 4–10 kg (9–22 lb) | 100–220 N (22–49 lbf) | 1–2 | Confirm against builder/kit requirements |
| Experimental cowling access panel | 2–5 kg (4–11 lb) | 60–120 N (13–27 lbf) | 1 | Weight-sensitive — smaller rod diameter |
| UAV/drone airframe access hatch | 1–4 kg (2–9 lb) | 50–100 N (11–22 lbf) | 1 | Lightest end of the range |
| MRO / hangar equipment panel | 5–14 kg (11–31 lb) | 130–250 N each (29–56 lbf) | 1–2 | Higher cycle count — verify duty cycle |
These figures are starting-point estimates. Final force depends on hinge offset, opening angle, and — as shown above — the weight tradeoff between rod diameter and fill pressure, so share your dimensions and target weight with our team and we’ll run the numbers rather than quote off a single force figure.
Why Ground Support and Experimental Aircraft Builders Source from Newtone
We’re a manufacturer, not a distributor. Every spring is built in our own facility in Turkey, which means we control tolerances, material sourcing, and lead times — not a third party.
Frequently Asked Questions
It depends which category the application falls into. Certified flight-critical hardware requires AS9100 production, NADCAP special process approval, DO-160 environmental qualification, and full material traceability through the airframe manufacturer’s approval chain. Non-flight-critical applications — ground support equipment, experimental and light-sport aircraft, UAV airframes, hangar and maintenance equipment — can legitimately use a well-engineered gas spring without that certification stack, provided force, temperature range, and corrosion resistance are specified correctly for the environment.
No. Newtone holds ISO 9001, ISO 14001, and ISO 45001 certification, but not AS9100 (the aerospace-specific quality management extension) or NADCAP special process approval, and we do not perform DO-160 environmental qualification testing. We supply custom gas springs for ground support equipment, experimental and light-sport aircraft, UAV airframes, and other non-flight-critical aerospace-adjacent applications, and we say so plainly rather than imply broader certification.
In many cases, yes, because owner-produced experimental aircraft and light-sport categories are typically accepted by the builder or kit manufacturer rather than requiring the same certified-parts chain as a Part 23 or Part 25 type-certificated aircraft. The builder or kit manufacturer’s own requirements govern this, so it should always be confirmed against the specific aircraft’s build standard before specifying.
A smaller rod diameter needs higher internal pressure to deliver the same force, since force equals pressure differential multiplied by rod area. A 6 mm (0.24 in) rod needs roughly 7.1 MPa (1,030 psi) to produce 200 N (45 lbf), while a 10 mm (0.39 in) rod needs only about 2.6 MPa (370 psi) for the same force — but the smaller rod and thinner body typically save meaningful weight, which matters more in aerospace-adjacent applications than almost anywhere else.
Yes. Newtone manufactures gas springs in Turkey and exports to more than 60 countries, supplying custom force, stroke, and material configurations for ground support equipment, experimental and light-sport aircraft, UAV airframe, and hangar equipment builders, alongside aftermarket replacement from the same product platform.
Conclusion
Most of the confusion around “aerospace gas springs” comes down to suppliers not drawing a clear line between certified flight-critical hardware and everything else. Once that line is clear, specifying a gas spring for ground support equipment, an experimental build, or a UAV airframe is a straightforward engineering exercise — force, temperature range, material, and for weight-sensitive builds, the rod-diameter-versus-pressure tradeoff.
Newtone supplies custom gas springs for exactly that non-flight-critical territory, with the scope of what we do and don’t certify stated plainly rather than implied. If you’re specifying a component for ground support equipment, an experimental or light-sport aircraft build, or a UAV airframe, share your dimensions, target force, and weight constraints with us.
