Case studies on the site include a WestJet fleet management project delivered in 2025. Another covers a CAMO airworthiness project that took distressed aircraft out of India. A third describes mid lease inspections carried out at global scale for a lessor. The company describes its work as nose to tail services that support compliance, efficiency and peace of mind.
