Constant Aviation Honored as First MRO to Attain WYVERN’s Highest Safety Management System Ranking

Constant Aviation announces it has become the first independent maintenance, repair and overhaul business (MRO) to receive SMS Level 4 certification from WYVERN Ltd., a recognized leader in aviation safety risk management and training. The rating is specific to MRO safety management systems (SMS). Level 4-rated MROs have a fully effective SMS.

Additionally, Constant Aviation’s functional SMS had been accepted by the FAA in April 2021, making it only the fourth MRO overall out of the more than 4,500 maintenance organizations nationally to achieve that designation.

“The recognition by WYVERN of our safety management system affirms our dedication to making the highest standards of safety part of our daily operations,” says David H. Davies, chief executive officer, Constant Aviation. “This achievement is made possible by ensuring that all of our team members have the skills, training, resources and conditions they need to ensure their safety, the safety of the flight crews, and the safety of the passengers who fly on the aircraft entrusted to us.”

Based on WYVERN’s SMS certification criteria, recognized by regulators and international organizations around the world, Constant Aviation will be ranked in the top tier of MROs in an app-based searchable network of maintenance providers maintained by MRO Insider.

“WYVERN’s SMS ratings will now be featured prominently within an MRO’s profile on the MRO Insider platform,” says Andy Nixon, founder and president of MRO Insider. “Overall, we want to work with WYVERN and industry-leading MROs such as Constant to generate enhanced visibility around the importance of SMS to motivate more MROs to strive for full adoption.”

Sonnie Bates, WYVERN’s CEO, says, “Recognizing Constant Aviation as the first MRO to attain our SMS Level 4 rating, together with our partnership with MRO Insider to clearly identify the SMS standing of each MRO, promotes WYVERN’s mission to elevate safety and security worldwide. Applying our well-established SMS evaluation tools in the MRO segment empowers owners and operators to make MRO selections holistically and instills confidence that they are partnering with a world-class aircraft maintenance organization.”
