Gastops delivers 20,000th MetalSCAN sensor to aerospace market

Gastops announced the delivery of its 20,000th MetalSCAN® oil‑debris monitoring sensor to the aerospace market during the Farnborough International Airshow, showing the Canadian firm’s long‑standing role in condition‑monitoring technology.

Milestone delivery at Farnborough

The sensor was handed over in June 2026 for Pratt & Whitney’s F135 engine program, the power plant behind every variant of the F-35 Lightning II. The event marks roughly three decades since the company began developing MetalSCAN® in the early 1990s, initially targeting the Pratt & Whitney F119 engine that drives the F-22 Raptor. The first production unit left the factory in 1997, and the technology has since become a standard component on several high‑performance propulsion systems.

Other platforms that now include the sensor are the Eurojet EJ200 engine for the Eurofighter Typhoon and the Pratt & Whitney GTF™ family, which powers a range of commercial aircraft.

Operators rely on MetalSCAN® to spot metallic particles in lubricated systems, a capability that supports condition‑based maintenance and helps avoid unexpected failures.

Impact on maintenance strategy

MetalSCAN® technology alerts crews to wear debris, giving them data to decide whether an engine needs inspection or can keep running. By reducing unnecessary checks, airlines and defense units can lower lifecycle costs while keeping aircraft ready for missions.

The sensor’s integration into the bill‑of‑materials of major engines means it is installed during production rather than added later as an aftermarket part.

Gastops, a small‑to‑medium enterprise based in Ottawa, sees the 20,000‑unit milestone as a validation of its research and partnership model. “For more than 35 years, our research and innovation, and collaboration with our partners have advanced our condition monitoring technologies that improve the safety, performance, and availability of critical aerospace assets,” said Daniel Obedi, Vice President, Aerospace Platforms at the company. He added that while MetalSCAN® remains a core product, the firm is also expanding its portfolio with complementary solutions such as ChipCHECK®, which broadens the range of diagnostics available to both commercial and defence operators.

The sensor has found use in marine, energy and other industrial sectors, taking worldwide deliveries past 50,000 units.

For technicians on the ground, the data can translate into a few concrete actions: schedule a targeted inspection, adjust oil change intervals, or confirm that a component is still within its expected wear limits.

Those decisions, made with real‑time evidence, can keep aircraft in the air longer and reduce the likelihood of costly unscheduled repairs.

In practice, the rollout of the 20,000th sensor means that a higher proportion of new aircraft will leave the factory already equipped with this monitoring capability.

Crews will no longer need to retrofit older fleets to achieve the same level of insight, which should ease logistical planning for airlines that operate mixed generations of aircraft.

Future outlook

The delivery comes at a time when the aerospace sector is emphasizing digital health monitoring and predictive maintenance. As engines become more complex and fleets grow, the amount of data needed to keep them running safely will only increase.

The company’s continued focus on sensor development and integration positions it to supply that data stream, whether for a fighter jet or a commercial airliner.

Industry observers note that the sensor’s inclusion in the design phase of engines like the F135 may set a precedent for future propulsion systems.

If manufacturers follow suit, the baseline for engine health monitoring could shift toward continuous, sensor‑driven analytics rather than periodic, manual checks.

The 20,000th MetalSCAN® sensor delivery highlights a blend of long‑term engineering effort and market adoption that has allowed a Canadian firm to maintain a foothold in a highly competitive field.

Next steps will likely involve expanding the sensor’s capabilities and integrating it with broader aircraft health‑management platforms.
