21jAeroDesign is a trusted industry provider of the design and supply of new aircraft parts. We have extensive experience in the re-engineering of ‘problem’ parts to improve reliability, whilst at the same time reducing cost. We work closely with our established production partners to guarantee short lead-times and a robust supply chain.

CFM56-5B Thrust Reverser Adapter Ring Outer Flange Segments
Operators of CFM56-5B powered A320FAM aircraft have experienced severe corrosion damage effecting the lower flange segments of the thrust reverser adapter ring.
As in this case, the aim of 21jAeroDesign is not just to reverse engineer the ‘problem’ part, but rather to re-engineer the part to eliminate the inherent reliability problems associated with the original design.
Detailed failure analysis has allowed 21jAeroDesign to systematically correct four key deficiencies in the original design by meticulous attention to the new design specification.
A320FAM Cargo Compartment Panels
Floor, sidewall, partition and ceiling panels.
New panels are CNC precision machined from Airbus approved FST compliant honeycomb sandwich materials and expertly assembled using OEM specification parts and adhesives.
Installation is approved under a Part-21 minor design change and new parts certified for release by EASA/CAA Form 1. An AIPC supplement is issued as part of the design data package, listing the new part numbers and showing interchangeability with the OEM part numbers.


Working in coordination with our customers, common part numbers are held in stock and available for immediate dispatch. CNC programming allows our production partner’s state of the art facility to manufacture to order under short lead-times.
