28 March, 2019: Jet Maintenance Solutions (Jet MS) has become one of the first MRO companies in the world to complete the 7800 landings inspection on a Bombardier Challenger 604 (CL604) type aircraft. There are just 5-10 CL604s globally that reached such milestone. Base maintenance work was also done after 48 months of exploitation.
To carry out the 7800 landings inspection, Jet MS engineers had to remove almost all of the main aircraft parts and components like engines, inner and backside fuel tanks, stabilizer and many others, which are not done during usual inspections after 48 and 96 months of aircraft operation.
“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,” said Darius Saluga, CEO at Jet Maintenance Solutions.
Aircraft was almost disassembled, and all construction parts were inspected and a number of non-destructive tests (NDT) such as x-ray, eddy current, ultrasonic, magnetic were performed.
If NDTs related works usually make up to 3 per cent of all base maintenance works scope, in this particular 7800 landings inspection they made up to 30 per cent.
For this aircraft type, 7800 landings inspection is quite rare in the market, as most of CL604s have not yet reached that milestone. This aircraft was used for intensive short-haul flights. It has made from 30 per cent to 90 per cent more landings than average CL604 makes.
Jet MS had to coordinate all technical issues with Bombardier while performing NDT. They had to communicate on technical documentation non-conformance cases and order the urgent basis (AOG) development for the standards that were not available in the market yet, search, set-up and tune of scanning probes and many more.
“Despite all the challenges, Jet MS team managed to get this maintenance project done efficiently and with quality, meeting demands of aircraft owner, “adds D. Saluga.
