If you are buying an aircraft it is essential that you invest in a thorough pre–buy aircraft inspection or survey and ACS Engineering can carry this out for you. We can ensure that the aircraft and paperwork records are thoroughly inspected by our skilled aircraft engineering team, which will:

Airworthiness Review Certificate (ARC)
Every European Aviation Safety Agency (EASA) aircraft that is registered in the UK and is operating on a full EASA Certificate of Airworthiness (CofA) is issued, at renewal, with a non-expiring CofA that is supported by an Airworthiness Review Certificate (ARC).
Airworthiness Review Certificates are valid for a period of 12 months. In order to allow legal flight to continue you need to ensure that before your ARC expires that a new ARC is issued or that the existing one is extended.
