    I always choose ASG for handling in Guernsey, because they are very friendly, it feels like I’m coming home! Nothing is too much trouble and on the odd occasion my aircraft has maintenance issues whilst I’m there, the engineers are very quick to sort things out and get me on my way. Bravo ASG!
  • PA46 Malibu owner

    ASG are very experienced on all Piper models, they maintained my previous aircraft before I traded up to my latest Mirage. I always get clear, detailed reports on what work needs doing along with cost estimates, before I commit to the work being done, which gives me peace of mind and enables me to budget ahead.

    ASG are easily the most experienced Commander maintenance company outside the USA. No wonder there are so many Commanders in their hangars when I visit them for maintenance – I simply would not trust anyone else with my aircraft, having used them for the last 5 annual inspections.

    I flew my Cirrus from Europe to ASG in Guernsey to have the CAPS replaced because they have a good reputation for fast, efficient service. I was not disappointed as they completed the work in 2 days at a fixed price that I was very happy with.
  • SR22 owner

    I’ve had my Cirrus maintained by ASG for the past 4 years, since it was new and I’m always impressed with their detailed knowledge of the aircraft and it’s systems. ASG have really looked after me and my aircraft, which still looks as fresh as when it was built.
