EASA Part 21J DOA · EASA.21J.849
Design Organisation Approval for modification concepts, structural and systems design, STC programmes, and approved data packages — AIR TEAM Engineering.
Design, Production, Handover — One Chain
EASA Part 21G POA · CZ.21G.0075
Production Organisation Approval for custom panels, cable harnesses, structural parts, and approved sub-assemblies built to DOA data.
Part 145 Handover
Installation, ground testing, and return-to-service at Kunovice — one trace from drawing number to certificate of release.
Five Programmes. One Engineering Team.
Modify, certify, convert, complete, or upgrade — each route starts with the same DOA discipline and ends with approved data ready to fly.
Modify
Modify Your Aircraft
The modification is approved. The programme is ready to fly. DOA design, POA parts, and installation readiness for STC and minor change programmes.
Plan a Modification
Certify
Certify Your Change
Certification starts with the data on the table. Change classification, compliance evidence, test coordination, and Part 145 handover package.
Start Certification
Convert
Convert Your Aircraft
A new role for the aircraft. One programme to get it there. Role change, medevac, VIP, special mission, and structural modification routes.
Shape Conversion Scope
Complete
Complete Your Interior
Interior complete. Documentation confirmed. Aircraft ready for the customer. VIP completions, connectivity, and redelivery support.
Discuss Interior
Upgrade
Upgrade Your Avionics
From panel cut-out to approved data. One avionics programme — glass cockpit, targeted upgrades, panel manufacturing, and cabin tech integration.
Plan Avionics UpgradeDifferent Aircraft. Same Engineering Discipline.
Business jet, commercial fleet, or government aircraft: the programme still has to hold together from first brief to approved data.
Business & Executive
Your aircraft. Your requirements. Our process.
For VIP operators, aircraft owners, management companies, lessors, and completion partners who need discreet programme control, precise documentation, and a clean route to delivery.
Typical use cases: VIP/VVIP completion, cabin refresh, redelivery, avionics personalization, glass cockpit retrofit.
Business ProgrammesCommercial & Fleet
Fleet change on schedule. Documentation complete. Aircraft back in service.
For airlines, fleet operators, lessors, and technical partners managing upgrades across aircraft where downtime, approved data, and repeatability matter from the first work package.
Typical use cases: mandated upgrades, retrofit programmes, redelivery and transition, LOPA cabin changes, ADS-B compliance.
Fleet ProgrammesDefense & Government
Mission-specific. Certified. Accountable.
For government and defense programmes that need accountable engineering, discreet coordination, and documented compliance across the full aircraft change.
Typical use cases: special mission configurations, role change, medevac, CASEVAC, and EMAR-type programmes.
Mission ProgrammesPlatform coverage: Airbus A320 family · Boeing 737 family · ATR 42/72 · turboprops · business jets · GA types · helicopters (incl. CS-29 design capability)
