Modification Concepts
Feasibility, impact assessment, and programme definition before design hours are committed.
What We Do
Modification concepts through manufacturing documentation — one DOA team owns the data package.
Structural & Systems Design
Loads, interfaces, wiring diagrams, and installation drawings to EASA CS requirements.
Technical Calculations
Weight and balance, EMI/EMC considerations, and performance substantiation where the change demands it.
Manufacturing Documentation
Approved parts lists, sub-assembly definitions, and POA-ready production data.
Approved Parts & Sub-Assemblies
Custom panels, harnesses, and structural components built under Part 21G to DOA release.
Supplier Coordination
OEM interfaces, STC holder liaison, and component traceability through the modification programme.
Fleet & Airline Modification Programmes
Repeat programme capability for fleet-wide implementation — one approved data package, rolled out across aircraft.
Cabin Modification Programmes
LOPA design, seat reconfiguration, galleys, lavatories, partitions, soft furnishing, windscreens, and lease return packages — for ACMI operators, charter airlines, regional carriers, and lessors.
Avionics Modification Programmes
ADS-B Out compliance, CPDLC readiness, cockpit modernization, and IPSS — fleet-wide repeat STC for airlines, charter operators, and CAMO managers.
In-House Cabin Component Production
Windscreens, partitions, seat covers, and ancillary parts manufactured under Part 21G POA to the same approved data — no external supplier on the critical path.

Certification Context
EASA Part 21J DOA · EASA.21J.849 — AIR TEAM Engineering holds Full DOA with self-approval for minor changes, STC programmes, and modification design.
Part 21G POA (CZ.21G.0075) produces approved parts to the same data package. Part 145 at Kunovice completes installation and return to service.
