Hahn Air Lines is now operating a fleet of Cessna Citation CJ4s for scheduled airline service, making the CJ4 the first Citation to be used for such a role, said manufacturer Textron Aviation. The German scheduled and charter airline operator uses the CJ4 for its 155-mile Dusseldorf-Luxembourg route.

According to Textron Aviation, the CJ4 is the first jet in its class to achieve authorization for use in airline service. As a member of the International Air Transport Association (IATA), Hahn Air was required to submit the CJ4 for an operational safety audit.

“Cessna is proud that the Citation CJ4 is the first business jet in its class to pass the IATA audit, proving it met or exceeded more than 1,000 rigorous standards for safety and advanced flight operations,” said Textron Aviation vice president of sales for Europe Tom Perry. “The CJ4 is an excellent fit for Hahn Air’s growth in scheduled and charter operations in what is one of the most dynamic business centers in Europe.”

The IATA Operational Safety Audit program assesses the operational management and control systems of an airline and it accommodates both FAA and EASA standards for commercial air transport. Several aircraft and operating modifications were made to the CJ4 to accommodate standards, including a locking cockpit door, other cockpit modifications, emergency lighting, passenger safety briefing and conducting flight operations with multiple flight crews.
