Expired ARC airworthiness review EASA

Sure many a forumite will dig thru the published paperwork, but as AFAIK for those 2 cases:

• if no repositioning need, the aircraft is readied for the ARC by an authorised person or company, then the ARC performed by either a NAA inspector, or a different designated person or company
• if the aircraft is to be flown before a new ARC can be issued, a ferry permit is required. Again, the aircraft will be readied/inspected according permit requirements by an authorised person or company, and then flown to the designed place following conditions as set by the NAA in the ferry permit
  For both of these matters, the NAA of registration will be the driving authority.

If you really have to reposition the aircraft without an ARC, then you need a one-time permit to fly from the CAA. Here in Czechia, it costs 700 Kč.
Alternatively, you can contract an authorised airworthiness inspector to perform an annual and issue an ARC right where your aircraft is. In this case, the annual and the airworthiness review should be done by one and the same person. The list of authorised inspectors in Czechia is here.

If it is only a couple of month overdue and still undeleted on registry, usually a normal part 145 maintenance shop (and in some cases certain CAO) can clear it for airworthiness again. If it needs repo, the shop needs to either have a standard procedure for AOG (aircraft on ground) procedures enabling them to do the work off site, or they have a special permit application to fly the aircraft out, the latter also being possible for certain cases of expired registry. The shop and/or the corresponding NAA will be the once to speak to.

@MichaLSA, an expired ARC is not a reason for deregistration of aircraft, otherwise long-term refurbishment projects would all lose their registration.
Part-145 organisations cannot issue an ARC, only Part-CAMO, some Part-CAO, authorised freelance inspectors and the CAA itself can.

Hmm… Not short term, but at least after something on the scale of 7 to 10 years, there is at least one CAA that starts inquiring whether you’ll get an ARC or will deregister the aircraft.

We have had several long term projects without ARC’s and very few questions have been asked. May be this is because the authorities know we always have a few back of the hangar projects that get done during slack periods.

As long as there is a reasonable expectation of the aircraft returning to service there is no reason to de-Register the aircraft.

@Ultranomad: My experience is different, expired ARC will get your aircraft off the registry at many NAAs. Happened twice to us: first year no problem, as it appears authorities accept that there may be repairs and upgrades hindering a new ARC, but second year in both cases we got a simple questionnaire. In one case the project was performed at a workshop and they were able to extend the period without ARC each year until the end of the project after 5 years – but had two workshop inspections looking also at the project in detail. The other one got deregistered by authorities in the fourth year, which was the way to the scrapyard for the project aircraft as it lost all grandfathering rights by that.

What is the rationale for a de-registration after x years?

I was told the requirement to show the active fleet on registration only – limited number of possible registrations.
