Shared standards. Aligned expertise. Collective responsibility.

Built on Collaboration

In aviation, progress is shaped by coordination, trust, and shared responsibility. In Türkiye, the aviation supply sector has grown steadily over the years, often developing in parallel rather than within a unified structure. THAT DER was established to bring these capabilities together.

The Association of All Aircraft Suppliers is a nonprofit industry organization based in İstanbul. It brings together companies across the aviation supply chain, from parts supply and manufacturing support to MRO, engineering, logistics, and training.

THAT DER strengthens collaboration and alignment across the sector, fostering closer engagement between industry stakeholders and institutions. Its work focuses on knowledge exchange, professional coordination, and long-term capability in line with international aviation standards.

By supporting a more connected and visible industry structure, the association contributes to the global competitiveness of Türkiye’s aviation supply sector.
