## Summary

The procurement process detailed here involves Defence Equipment and Support, a central government public authority based in Bristol, United Kingdom. This process pertains to an extension of the TIESE (Troop Insertion and Extraction System Equipment) contract for a further twelve months, specifically focused on services related to special-purpose aircraft and helicopter repair and maintenance. The procurement method used is a direct award, attributable to technical reasons, particularly since IrvingGQ Limited holds exclusive technical expertise, proprietary information, and the necessary certifications pertinent to these activities. The contract period spans from 1 April 2026 to 31 March 2027, with significant milestones scheduled, such as the future signature date set for 30 March 2026.

This tender presents considerable opportunities for business growth primarily for suppliers with established expertise in the defence and security sectors, particularly those specialising in aircraft systems and helicopter maintenance. While the procurement method of direct award limits wider competition, it ensures that the intricate standards and technical competencies required by the UK's Military Aviation Authority’s regulatory frameworks are fulfilled. Businesses with a specific focus on defence aerospace technologies may find potential collaboration with IrvingGQ advantageous, despite their exclusive ownership of the necessary certifications and technical skills pertinent to the TIESE system.

## Notice

Extension of a further twelve (12) months to the existing CHC/647 TIESE (Troop Insertion and Extraction System Equipment) contract.

### Procurement Information

IrvingGQ are the original equipment manufacturers and Design Authority of the TIESE fitted on the UK Chinook aircraft. As such, the In Service support of the TIESE (including the provision of repairs and spares) together with the related Project Management, can only be carried out by IrvingGQ as IrvingGQ exclusively holds the relevant skills, technical data, proprietary information (including drawing and design information) and know-how that is needed to meet the requirement. IrvingGQ previously confirmed that it is not prepared to share or license the use of that proprietary information outside of the Company and the UK Ministry of Defence does not have a right to obtain the necessary documentation from IrvingGQ. The aforementioned skills, technical data, drawing and design information are necessary for the performance of the requirement. Furthermore, only IrvingGQ holds the level of certification (under the Authority's Design Approved Organisation (DAOS) and Maintenance Approved Organisation (MAOS) Schemes) necessary to carry out the activities that are required in order to meet the Military Aviation Authority's Regulatory Articles applicable to TIESE. It is not possible for another company to obtain the relevant level of certification without access to the skills, knowledge and technical information that only IrvingGQ hold.
