Aircraft registered in the Swiss Aircraft Registry must either undergo an annual airworthiness review (EASA aircraft) or a review every two years (Non-EASA aircraft).
- Aircraft that fall within the scope of the EASA Basic Regulation (EC)
N° 2018/1139 (EASA aircraft) must generally inspected every 12 months in order to confirm their airworthiness. The airworthiness is attested with the issuance of an airworthiness review certificate
(ARC EASA Form 15) which is valid for one year. The airworthiness can be inspected either by authorized personnel or by an authorized organization (CAMO/CAO) or by the FOCA.
- In the case of aircraft that fall outside the scope of the EASA Basic Regulation, i.e. which are listed in Annex I to the Regulation
(Non-EASA aircraft), the Ordinance on the Airworthiness of Aircraft
(VLL; SR 748.215.1) applies. These aircraft are inspected exclusively by FOCA. The confirmation of review is valid for 2 years.
If the airworthiness review for an aircraft is due, ideally a review should be carried out in the 90-day period before the expiry date of the airworthiness review certificate or the confirmation of review. Aircraft without a valid airworthiness review certificate or a valid confirmation of review may no longer be operated. Infringements of this rule may lead to criminal prosecution.
For the operators of privately operated, non-complex aircraft in particular, the FOCA sends an information letter regarding the expiry of the validity and the examination agreement.
