Jet Maintenance Solutions (Jet MS), a part of Avia Solutions Group, became one of the first MRO companies worldwide to complete the 7800 landings inspection on a Bombardier Challenger 604 (CL604) type aircraft. There are only 5-10 CL604s globally that have reached this milestone. Additionally, base maintenance work after 48 months of operation were also carried out.
“The experience and professionalism of Jet MS team, close coordination with aircraft producer, have enabled us to complete this challenging project successfully. This is a major achievement for our company and proof of our ability to solve complex and non-standard cases effectively,” says Darius Saluga, CEO at Jet Maintenance Solutions.
To perform the 7800 landings inspection, Jet MS engineers had to remove a majority of the main aircraft parts and components including engines, inner and backside fuel tanks, stabilizer and many others, which is not done during usual inspections after 48 and 96 months of aircraft operation.
Aircraft was almost disassembled, and all construction parts were inspected and a complex of non-destructive tests (NDT) such as x-ray, ultrasonic, eddy current, magnetic were performed.
That was a major and most crucial part of all the maintenance tasks. NDT inspections and related work usually make up about three percent of all base maintenance works scope. But, in this particular 7800 landings inspection, they made up almost 30 percent.
7800 landings inspection for this aircraft type is quite rare in the market, as most of CL604s have not yet reached that milestone. This particular aircraft was used very intensively in short-haul flights – making from 30 percent to 90 percent more landings than an average CL604 makes.
While performing the NDT inspections, Jet MS had to coordinate all technical issues with Bombardier, including communicating on technical documentation non-conformance cases and order AOG development for the standards that were not available in the market yet, search, set-up and tune of scanning probes and more.
“Despite all the challenges, Jet MS team managed to get this maintenance project done efficiently and with quality, meeting demands of aircraft owner,“ says CEO Saluga.
