Engineering Manager, Aircraft Appliances and Equipment Limited (AAE)

“We use a Cotta gearbox on our in-house stands used for testing aircraft generators, typically 60kVA to 90kVA. The gearbox has run for over 25 years without a major breakdown. When we’ve ever needed a part or reported a service issue, Cotta is always responsive and meets our need within a week. They have a good, very consistent group of people there. We may need to install another test stand in the future. So, when we need a new high-speed gearbox, Cotta is who we’ll call. AAE has specific requirements for stringent applications, like for running an F-18 aircraft generator at 26,000 RPM, and we can rely on high-quality results from their product.”
