MRO provider Constant Aviation has closed its facility at Phoenix-Mesa Gateway Airport (IWA), an airport official confirmed to AIN today. Airport spokesman Ryan Smith said the airport wasn’t given any official notice by Constant but learned of its closing by employees there turning in their security badges.

“Tuesday was the day I believe they notified employees,” Smith said. Constant was subleasing the 75,000-sq-ft building it occupied, which is likely the reason the airport was never officially notified, Smith added. “There were no conversations or anything like that.”

An official at the Cleveland, Ohio-based company didn’t immediately return voicemail and email messages to AIN on Monday morning. The company, which operates MRO facilities in Cleveland and Orlando, Florida, opened the IWA location in November 2017. The facility included a 50,000-sq-ft hangar. At its opening, the facility was expected to eventually employ 150 workers. It isn’t clear how many were employed there at the time of its closing.

In other Constant news, Stephen Maiden confirmed to AIN that he left the company as CEO effective January 1 but didn’t cite reasons for doing so. “I’ve been presented with a few opportunities to expand my career and I’m excited about the future,” Maiden said. “Constant Aviation including Nextant Aerospace is made up of some of the brightest minds in the industry and I’m beyond grateful for the team, their hard work, and determination to help grow Constant into what it has become. And I look forward to their continued success.”
