Low-cost carrier Frontier Airlines has selected Lufthansa Technik to repair and overhaul 21 CFM56-5B engines as well as to supply mobile engine services.

Under the terms of the five-year contract, Lufthansa Technik will perform overhauls and surgical repairs on the engines, which are installed on Frontier’s fleet of 112 Airbus A320 family aircraft.

Overhauls will be conducted at Lufthansa Technik’s Hamburg, Germany, base, while surgical repairs can be conducted locally at the company’s facility in Tulsa, Oklahoma. New tooling has been acquired for this latter facility, while its existing test cell has been upgraded to cover CFM56-5B testing and mechanics have received training.

Mobile engine services will also be performed in Tulsa for repairs necessary between overhauls, with the aim of significantly reducing operational downtime and avoid unnecessary shop visits.

Depending on the requirements of the individual repair solution, the available options range from on-wing and in-field services to more complex repairs performed at the shop in Tulsa.

“Lufthansa Technik is an important and longstanding partner for us, which makes us confident that they will meet our high expectations regarding engine maintenance, flexibility, and price,” said Frontier Airlines’ senior vice president of operations Trevor Stedke.

Lufthansa Technik’s vice president engines Dietmar Focke commented: “We are extremely happy that we were able to win the trust of Frontier. Engines are the most valuable asset of an aircraft. We look forward to growing our partnership and support Frontier’s growth, as one of the most successful airlines in the American market, with a focus on providing affordable air travel throughout the US and beyond. We will fulfil the trust placed in us and prove that we can provide high-quality and reliable services at a reasonable price.”
