About
Airline technical judgement. Trading-floor commercial sense.
Harrier Aviation Advisory is a boutique advisory firm, led personally by its founder, for lessors, traders and USM suppliers.
Founder & Managing Director
Antonio Rodríguez Feans
Aeronautical engineer with more than twelve years of hands-on experience across the full life of an aircraft asset — from airline operation and the engine shop to USM, leasing, trading and asset management.
His background brings together the operational, shop and commercial views of the same asset. He has worked in airline continuing airworthiness, in the engine shop on shop visit documentation, on the redelivery of aircraft and engines, and on the leasing and trading side, assessing assets for acquisition, lease and part-out. Each stage adds a different reading of the records: how the asset was operated, how it was maintained and repaired, and how the market will value it.
That broad view is matched by detailed work at every stage. Daily use of the technical manuals, service bulletins and airworthiness directives, and a working knowledge of each process from removal to release certificate, give every conclusion a solid and verifiable technical basis — and show where the records add value to the asset and where they put it at risk.
As Technical Director he led technical teams through records audits, transitions, workscope decisions and pre-acquisition assessments, setting the standard of detail and reviewing every deliverable.
He founded Harrier Aviation Advisory to apply that experience personally to every asset: technical confidence down to the detail, and a clear view of how each finding affects the value of the asset.
