First Vision Jet SF50 100 Hours Inspection at Air Service Basel

Air Service Basel has taken on its first 100 hours inspection for a Vision Jet SF50. Our Maintenance Manager, Pirmin Schärli, takes us through the project - and highlights a couple of surprises along the way!

For those of you who may be unaware, every aircraft has to be inspected after a certain number of flying hours to comply with international maintenance regulations.

Inspection intervals are based on flight hours, aircraft cycles (amount of flights) or calendar months. These intervals depend on the manufacturer, model and size of aircraft as well as of the country where the aircraft is registered.

The Cirrus Vision Jet SF50 needs to be inspected when it reaches 100 flight hours or every 12 months if you don’t reach 100 hours in the year.

As with any inspection, the team go through the manufacturers manual step-by-step and check off every item. The standard tasks on all aircraft include a detailed list of components and systems. Checks are completed throughout the cabin of the aircraft, in the cockpit, the landing gear, as well as engine and flight controls.

For this project on the SF50, we had 20 Service Bulletin’s (SB’s) to work on, an average would be between 5-10 but as the Vision Jets are still new products, there are increased bulletins to ensure the highest level of safety, quality and reliability is obtained on the aircraft.

While working on this project we also received an emergency SB from Cirrus stating that all Vision Jet's needed to go into maintenance because of a fault with the circuit cards. It took about another 8 hours of work to remove the interior panels, extract the cards and reinstall the interior panels on this aircraft. Due to the announcement, we had 4 more AOG's to work on Vision Jets in various locations around Europe, which made it a busy week. The team managed really well and by the end of week all of our aircraft were ready to return to service.

We have several Cirrus technicians in-house who are fully trained on composite aircraft, but a particular highlight for me has been working on the Vision Jet because its a complete carbon fibre composite aircraft. I personally have experience working with composite materials but not for the whole structure, the SF50 is the first composite jet that I work on with the team, so I'm pleased to tick off a personal milestone on this project as well.

Cirrus also has an emergency system which is very innovative. I’ve worked on SR20’s and SR22’s with the FAA & EASA certified parachute system but the new generation of Vision Jets will have an additional emergency landing feature that will allow it to land automatically. I’m looking forward to seeing and learning more about it.

That’s a quick overview of our first Vision Jet SF50 100-hour inspection.

If you have any questions or comments let me know and I’ll get back to you.
