Zrakoplovno-Tehnički Centar

What Zrakoplovno-Tehnički Centar does

Zrakoplovno-Tehnički Centar d.d. (ZTC-ATC) is a Croatian state-owned joint-stock company headquartered in Velika Gorica that provides comprehensive maintenance, repair, and overhaul (MRO) services for military and civilian aircraft and helicopters. The company's portfolio covers firefighting aircraft (Canadair CL-415, Air Tractor AT-802), combat aircraft (MiG-21), combat and transport helicopters (Mi-8/17, Mi-171Sh, UH-60M Black Hawk), and training aircraft (Pilatus PC-9), supported by in-house laboratory, parts production, workshop, and 24/7 Intervention Team capabilities. Its primary customer is the Croatian Ministry of Defence / Croatian Air Force, with additional civil work for Croatia Airlines and international MRO contracts for Spain, Slovenia, North Macedonia, Montenegro, and (via Saab AB) Sweden.

ZTC generates revenue almost exclusively through negotiated multi-year government contracts and project-based MRO work; pricing is not publicly disclosed and labor rates were adjusted in 2024 for the first time in roughly 12 years. Distribution is direct and physical: aircraft are brought to the Velika Gorica facility, or mobile workshop teams deploy to customer sites during fire season. The organisation is EASA Part 145 certified, holds state-owned designated-entity status for Croatian national defense, and operates as a single integrated service organisation rather than a productised software or SaaS business.

Since November 2022, leadership under CEO Ivica Vidović has driven an operational turnaround: a new Collective Agreement (April 2024), new Salary and Systematization Regulations, and salary increases of 27% aggregate and 37% for aviation technical personnel. Operational metrics improved from late delivery cycles to delivering the full 12-aircraft firefighting fleet before the 2026 season for the first time. The company is also diversifying revenue via its Velika Gorica role in the €62.5M, 7-year Croatian Emergency Helicopter Medical Service (HHMS) consortium awarded in October 2023.
