Barton Aerodrome Maintenance Facilties

Our Part CAO approval (UK.CAO.0096) enables us to carry out ARC issues and extensions.

Careful and thorough record keeping is essential nowadays and the best way to ensure this is to have your aircraft maintained on a constant basis by a Part 145 approved maintenance organisation such as Westair Engineering Services. This ensures that the required maintenance is carried out and properly recorded, Airworthiness Directives and Service Bulletins are monitored and reviewed on a regular basis making ARC renewals a simple and inexpensive matter.

Airworthiness Review Certificates

The Airworthiness Review Certificate (ARC) is designed to ensure that all aircraft have a “life history”, a traceability for all Airworthiness Directives, mandatory Service Bulletins as well as Minor and Major modifications. It is also to verify the required servicing has been carried out in accordance with CAA, EASA & FAA regulations.

Basically all aircraft, to be legally issued an ARC, must have complete and concise traceability check carried out by either an approved company such as Westair Engineering Services, or by the CAA.


The Costs

At Westair, we can issue Initial Airworthiness Review Certificates at highly competitive prices. We also offer a complete Airworthiness Management Contract Package.

We will ensure your aircraft log books, Service Bulletins, Airworthiness Directives and all associated records are maintained to EASA requirements, which allows us to issue ARC`s instantaneously, saving you a great deal of hassle, time and the expensive costs of having an initial ARC every year.

Having Westair Engineering Services control the airworthiness for your aircraft means you only need an initial ARC every 3 years with the subsequent 2 years being a simple extension.
