I have worked with SWS on a large project for the new crest rest installation on our Neos fleet. SWS are very professional and offer strong support, providing work on time. We have a very positive working relationship and can communicate effectively with SWS to collaborate and accomplish a common goal. SWS are brilliant at finding inventive ways to solve problems and move forward in our projects to gain the necessary approvals.
SWS has delivered an excellent and efficient service to aid the certification of our product on a very aggressive schedule.
Altitude contract SWS for their specific expertise in certification issues, and have continued to be impressed and have confidence in their ability to deliver. SWS Certification Services provided an EASA minor approval on a B737 VIP package, as with our previous experiences, SWS provided a very efficient service to a tight schedule.
SWS is the first choice for Airline Services Interiors for all our seat certification support and testing requirements, due to their in depth knowledge of aircraft seating, both mechanical and electrical.
The expertise and knowledge of SWS Certification Services has assisted Thompson Aero Seating to gain ETSO and TSO approval for our Vantage seats, as well as providing follow up data to enable seat installations via STC.
