Independent Structural Airworthiness Advisor (ISAA)

Our ISAAs work on client sites and remotely to provide prompt advice to engineering Delivery Teams. It is our rapid, flexible engagement and subsequent clear and concise independent advice that has proved invaluable to our customers in gaining immediate SME airworthiness advice that has assisted TAAs in making well informed airworthiness decisions. Typically, our ISAAs provide support in the following aspects of Structural and wider Integrity Management:

Usage Validation programmes

Our ISAAs understand in detail the requirements of MOD MAA Regulation (RA5726) and associated guidance material to carry out Operational Loads and Usage Validation via a suitable and appropriately scoped Operational Data Recording (ODR) programme (RW) or Operational Load Monitoring (OLM) programme (FW). Specialising particularly in using the most suitable methodology for each type, AR has unrivalled experience in innovative approaches to RW ODR. We support TAAs with the development of an ODR strategy and assessment of Usage data.

Statement of Operating Intent and Usage (SOIU)

Our ISAAs carry out expert independent annual and triennial reviews of platform SOIUs with the support of usage data analysis and in conjunction with one to one Aircrew interview panels.

Ageing Aircraft Audit (AAA)

Our ISAAs develop bespoke AAA strategies and plans that meet the regulatory guidelines in RA5723 and subsequently deliver full audits to enable platform TAAs to quantify the airworthiness risk due to the platform ageing.

Independent Technical Evaluator (ITE)

TAAs require our ISAAs to provide ITE assessment on a range of Type Airworthiness issues (e.g. Type Design changes, Release to Service changes, repairs, modifications, urgent operational airworthiness and structural damage issues and many more aspects concerned with maintaining platform integrity).

Independent Structural Airworthiness Advisor
(Rotary Wing, Fixed Wing & Remotely Piloted Air Systems)

We support MoD DE&S Delivery Teams with our team of highly specialist expert Independent Structural Airworthiness Advisors (ISAA). Our ISAAs provide independent Structural Airworthiness advice and Integrity Management (IM) support to Platform Type Airworthiness Authorities (TAA) on all Structural and wider IM aspects through life in accordance with Military Airworthiness Authority (MAA) Regulation (RA 5726).

Our ISAAs are key members of Structural, Propulsion and Systems Integrity Working Groups and through active participation at these forums our ISAAs inform the TAA’s assessment of the status of IM of the platform. An essential element of this assurance process is to have a periodic review of the manner in which the aircraft is operated; to confirm that usage assumptions, and thus strength substantiation remain valid. This requirement is achieved initially by independent review of the Statement of Operating Intent and Usage (SOIU).

AR ISAAs are also members of the MAA led MASAAG and AAPWG.
