In order to be considered capable of safe air navigation, aircraft needs to be repaired and regularly maintained in accordance with the approved maintenance programme.
Depending on the purpose of aircraft and complexity of required services, maintenance may be carried out by:
- approved maintenance organisations,
- licenced avio-mechanics,
Maintenance organisations and mechanics are approved (certified) by Croatian Civil Aviation Agency in accordance with enforceable EU regulations. Therefore, their certifications will remain valid in EASA member states and EASA approved organisations even after Croatia's accession to EU.
Annex II aircraft maintenance organisations and mechanics are approved (certified) in accordance with national regulations effective in Croatia, and therefore their approvals are valid only in the Croatian territory.
