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


WYVERN Level 4 SMS Certification Unprecedented in MRO Industry

Constant Aviation, WYVERN and MRO Insider Collaborate to Enhance MRO SMS Visibility and Adoption Industry-wide

CLEVELAND, OH:  Constant Aviation today announced that 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), and 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,” said 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 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,” said 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, said, “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.”

About Aviation Safety Management Systems

Safety Management System (SMS) data have been maintained by the International Civil Aviation Organization (ICAO) since 1997. Analyses of these data demonstrate that SMS programs help mitigate aviation safety risk. As a result, the SMS concept has become the standard for safety programs in aviation worldwide. Although SMSs are optional for Constant Aviation and other maintenance and repair organizations (MRO)s, they increasingly are requested by both domestic customers and foreign certificate holders.

The Federal Aviation Administration (FAA) Part 5 SMS Program, established in 2015, provides aviation organizations with systematic procedures, practices and policies to manage safety risk. Constant Aviation has progressed through the program’s three levels: Active Applicant, Active Participant and Active Conformant. Having gained Active Conformant status, coupled with other progressive SMS achievements, has  merited Constant Aviation receiving WYVERN’s first-ever SMS Level 4 certification specific to MROs.
