Inspired thinking for the global market.

Inter-Tec Services Limited is a leading design, analysis, certification, problem- solving and training specialist serving aerospace clients around the world. The company has a highly experienced and skilled technical team that consistently rises to customers’ challenges to produce exacting and quality results across an extensive range of aircraft and helicopter platforms.

In 2005, Inter-Tec gained AS/EN9100 Approval which was up scaled in 2013 to Revision C, making them of the first consultancies in the UK to achieve this. Building on this, they enhanced their service offering in 2012 by gaining EASA Part 21 Subpart J Design Organisation Approval for Modifications and Repairs on aircraft and helicopter types, which catapulted their position within the global market. Due to their increasing presence in the Middle East, they added the GCAA Design Organisation Approval in 2013, to serve their customers in the UAE.
