D Check Heavy Maintenance Slots A320 B737 MD-80 Sofia Bulgaria
NEDAVION provides heavy maintenance and D-Check slot availability in Sofia, Bulgaria for operators, lessors and asset owners operating A320, B737 and MD-80 aircraft. Heavy maintenance is performed at a fully licensed EASA Part-145 partner facility, supported by structured slot planning, engineering coordination and controlled execution to manage extended downtime and complex work scopes.
D-Checks represent the most comprehensive level of aircraft maintenance, involving deep structural inspections, corrosion control, systems overhauls, cabin refurbishment, modification embodiment and major compliance tasks. Slot availability is limited by hangar capacity, engineering resources and planning windows, making early reservation and disciplined project coordination essential.
