Context and positioning

Civil and business aviation is the core business of Kronos Engineering. Drawing on hands-on practice since 2009, we support the full aerospace value chain — OEMs (Airbus, Boeing, Dassault, Embraer, ATR, Bombardier, COMAC, Irkut), engine makers and Tier 1s (Safran, GE, Rolls-Royce, Pratt & Whitney, Honeywell, Liebherr, Collins Aerospace), commercial aviation and airlines (Air France-KLM, Lufthansa Group, IAG, Emirates, Qatar Airways, Singapore Airlines, Delta, United, ANA), business aviation and business jets (Dassault Falcon, Gulfstream, Bombardier Global, Embraer Executive, HondaJet, Pilatus, Cirrus), air cargo (FedEx, UPS, DHL Aviation, Cargolux, Atlas Air, Turkish Cargo, P2F Passenger-to-Freighter conversions) and MRO / maintenance (Lufthansa Technik, AFI KLM E&M, ST Engineering, AAR, HAECO, SR Technics, Iberia Maintenance, TAP M&E, Ameco, Joramco, ADAT, Emirates Engineering, GMF AeroAsia). Our special processes secure the fatigue life of structures and equipment — shot peening, cold working, HFMI, flapper peening, roto peening, precision boring.

We operate within the NADCAP Surface Enhancement and EN 9100 / AS9100 frameworks and OEM specifications (Airbus ABP, Boeing BAC, Safran, GE, Rolls-Royce) — directly for industrial customers and airlines, or as subcontractor and on-site support for approved organisations — on the most critical parts: primary structures, engine disks, landing gears, flight controls. Our teams also operate in line maintenance and 24/7 AOG worldwide, embedded within PART-145 organisations. Our expertise covers OEM serial production, scheduled maintenance (C-check, D-check, Heavy MRO), Line Maintenance, Component MRO, Major Repair and 24/7 AOG — worldwide.

Commercial aviation and air transport — short/medium/long-haul fleets A320/A321neo, A330, A350, A380, B737 Classic/NG/MAX, B747, B777, B787, ATR 42/72, E-Jets, CRJ. Business aviation — landing gears, wings, flight controls on business jets. Air cargo — reinforced structures, post-P2F-conversion rework, extended cargo-cycle life. Independent MROs — we operate as Tech Rep or process subcontractor inside your shop, worldwide.

Typical operations

Serial production — OEM assembly lines

Interventions on A320, A350, A220, 787, ATR, Falcon lines. Shot peening, cold working and flapper peening integrated into the production flow.

Heavy MRO — C-check, D-check, 6Y/12Y

Major repairs, Service Bulletin and Airworthiness Directive mods. Structures technical file, execution and documentation.

Line maintenance & AOG

Immediate aircraft intervention on the tarmac or in a hangar. On-wing flapper peening, in-line cold working, 2h response, 24h deployment.

Structures Tech Rep at third-party MRO

Kronos structures expert inside the MRO of your choice — repair monitoring, quality validation, technical interface.

Major Repair Data and repair files

Structures engineering office: MRB, stress notes, DOA files for repairs outside the SRM.

Business aviation — Falcon, Gulfstream, Global, HondaJet

Business jets: engine shot peening, wing flapper peening, bore cold working. Intervention at FBO or OEM shop. Owner confidentiality.

Airline maintenance — short/medium/long-haul fleets

Intervention on A320/A321neo, A330, A350, B737, B777, B787, ATR, E-Jets at major MRO bases / hangars. Bore cold working, critical-zone flapper peening, engine-component shot peening.

P2F conversion and cargo

Reinforced structures, post-passenger-to-freighter-conversion rework. Shot peening and cold working of modified zones to extend cargo-cycle life.

Frequently asked questions

Within which framework does Kronos operate in civil aviation?+

Our processes are performed within the NADCAP Surface Enhancement (shot peening, flapper peening), EN 9100 / AS9100, AMS 2430, AMS 2432, AMS 2590 and BACC 5060 frameworks, and to Airbus, Boeing, Dassault, ATR and Safran OEM specifications — directly or as a subcontractor for customers and approved organisations (including PART-145 organisations for maintenance).

Can you intervene on an aircraft in AOG?+

Yes. Our 24/7 AOG on-call service dispatches a technician qualified in flapper peening / cold working / manual shot peening with their tooling within 24 hours at most international airports. Phone response within 2 hours. Dedicated line +33 7 69 51 61 26.

Do you handle Major Repair files?+

Yes. Our structures engineering office produces the stress notes, repair instruction, MRB file and full traceability for off-SRM repairs. Support up to authority validation (EASA / FAA / ASND).

Can we hire a Technical Representative from you?+

Yes. Our Tech Rep service places a Kronos structures expert inside the MRO of your choice — anywhere in the world — to monitor the repair, validate quality and interface technically with your workshop.

Do you work on military aviation?+

Yes, under appropriate clearances (defense confidentiality). Our scope covers fighter aircraft, military helicopters and Service Life Extension Programs (SLEP). Dedicated contact for classified files.

Do you operate for airlines?+

Yes. We operate for airlines and their partner MROs — short-, medium- and long-haul fleets. Cold working, flapper peening, engine-component shot peening. Directly or via AOG / Tech Rep inside the maintenance hangar.

Do you cover business aviation (business jets)?+

Yes. Business jets Falcon, Gulfstream, Bombardier Global, Embraer Executive, HondaJet, Pilatus, Cirrus Vision. Confidential intervention at FBO or OEM shop. Shot peening / flapper peening / cold working on landing gears, wings and flight controls.
