Quality Aircraft

From the beginning of AT Aviation in 2012 the writing was on the wall.

A combination of passion, business acumen and a desire to offer unmatched customer service, allowed Andy to grow the company at an explosive rate.

As in any situation where people are following their hearts and are passionate about what they are doing, the addition of focus, determination and hard work ensures that the right things happen at exactly the right time.

This continues to be the case today, and is the ethos with which AT Aviation forges forward.

Totally unmatched in the aviation space, we hold the largest stock in Europe with over 40 aircraft for sale, both on and off market, all on display in our showroom hangars at our Dunkeswell Aerodrome facility in Devon.

We have a constant stream of clients from the UK, Europe and beyond, many of whom enjoy spending a few days with us, our airport pick up services, and the various accommodation options we have available.

Now with a fully licensed maintenance facility and a helicopter flight training centre, 2019 is proving to be the start of a new phase of expansion for AT Aviation.

Anything is possible with the right attitude, and the right team.

The Team

Introducing AT AVIATION

Andy Twemlow

MD / Founder

Andy Twemlow our Founder (Mr T) enjoyed over 25 years in lead roles within the office automation sector. Following two sales director roles, Andy founded Peninsula business systems which developed into a highly successful multi million-pound turn over operation with over 50 staff.

Andy is married to Debs who supports his high-speed activities that have previously included 2 UK championship wins in Offshore Powerboat racing.  In 2010 Andy sold his controlling share in Peninsula to then find time to develop his love of aviation. Andy has clocked up several hundred types, flown in nearly 1300 hours of fixed wing flying in the last 5 years and has more recently moved to the dark side of rotary with over 300 hours flown in under 1 year.

As a serial entrepreneur, with a far-reaching network of contacts, Dean naturally builds new business relationships.

Now with a moderate to severe case of “the aviation bug,” he has thrown himself into both fixed wing and rotary training, from our new facility at Dunkeswell in Devon.
