Engineering design and regulatory support

Reverse engineering, design and approved modifications.

Practical engineering solutions for ageing aircraft, turbine engines and specialist components where original design support, materials or supply chains are limited.

Engineering beyond obsolescence

From a technical problem to a substantiated solution.

AFM combines hands-on aircraft and propulsion engineering with access to UK CAA BCAR A8-21 design organisation capability through an approved partner. This enables us to support reverse engineering, component recovery, repair development and proposed major or minor modifications.

Our approach brings together inspection, measurement, technical investigation, design data, calculations and, where needed, testing to build an engineering substantiation package appropriate to the application.

Not every legacy component can be reproduced or repaired economically or safely. Each proposal is assessed against its technical evidence, material and manufacturing requirements and the applicable approval route.

Engineering capabilities

Design and reverse engineering support.

Reverse engineering and component recovery

Engineering assessment of legacy or unavailable parts using available samples, drawings, dimensional and material analysis and technical evidence to establish a substantiated replacement or repair route. Any resulting design and embodiment require appropriate approval.

Engineering substantiation

Preparation and coordination of technical justification, drawings, calculations, material and process specifications, inspections and supporting test evidence appropriate to the proposed change.

Major and minor modifications

Support for airframe, systems, turbine and component changes, with classification, design substantiation and approval managed through an appropriately approved BCAR A8-21 design organisation partner.

Repair schemes and obsolescence

Investigation and development of proposed repairs and material substitutions where original parts, materials or processes are no longer practical, including suitable alternatives to legacy gasket materials.

Airworthiness and embodiment

Coordination between design, maintenance and continuing airworthiness functions so approved changes are incorporated into applicable maintenance data, records and ongoing inspection requirements.

Legacy fleet engineering

Integrated technical support for military, defence, commercial and specialist aircraft operators facing discontinued OEM support and fragmented supply chains.

Regulatory framework

Clear separation of approval responsibilities.

Atlantic Flight Maintenance holds UK CAA BCAR A8-23 maintenance and A8-25 continuing airworthiness approvals, subject to their respective approved scopes and privileges.

Design approval capability is provided through an appropriately approved BCAR A8-21 partner organisation. AFM can contribute technical investigation, engineering definition, substantiation and programme coordination, but AFM does not itself claim to hold that partner design approval. Modification and repair classification, approval and embodiment depend on the specific proposal and applicable regulatory requirements.

For turbine and airframe changes, we work with the design approval partner to establish the appropriate evidence and approval pathway before embodiment.

Examples of applications

Keeping legacy equipment supportable.

Applications may include substitution of obsolete materials, replacement gasket solutions for legacy turbine engines, assessment of unavailable airframe or engine components, alternative repair methods and modifications to maintainability or serviceability. Each is subject to technical assessment and the necessary approved data.
