Increased safety with maintenance check flights

Maintenance check flights (MCFs) are of the utmost importance for the safety of all aeroplane and helicopters. They serve to test functions, which can only be checked during actual flights. MCFs are time-intensive, demanding and subject to strict processes. The experienced specialists in our licensed center of excellence guarantee that maintenance check flights and training sessions will be impartial and qualified. As a part 21J EASA design organization with our own flight testing operation, we meet all the requirements set out by the European Union Aviation Safety Agency.

With the new EASA regulations, all operators are now required to train their crews for check flights and to describe the corresponding procedures in a manual. On this page you will find all information about our course offers and the registration process for aeroplane and helicopters.

Advantages of maintenance check flights


Increased safety

Maintenance check flights form an essential safety component for aeroplane and helicopters. By conducting intensive checks of all functions after maintenance, we work with you to ensure the safety of your crews.

Customer-specific training courses

Your requirements are at the heart of our concerns. We provide you with tailor-made training courses with a view to optimizing your resources and increasing safety.

RUAG boasts long-standing experience as a service provider: Approximately 130 pilots and technicians have benefited from the professional training courses run by experienced RUAG factory and test pilots in the field of helicopter maintenance check flights.

Our course offer for you

  • Aeroplane
  • Helicopter

EASA is now regulating MCFs as of this year: Operators of “complex aircraft”* will be required to train an MCF crew to carry out Level A maintenance check flights and to describe the procedures in a manual. These requirements have already been in place for helicopters since 2019 (learn more about MCFs for helicopters). In Switzerland, these regulations came into force on 1 February 2020.

Theory training
