Membership is derived from the manufacturer's own designation grammar — the same grouping the crosswalk search shows — and restates recorded relations only. Search any variant on the Spec-Crosswalk for the graded view.
This crosswalk identifies candidate equivalents with cited evidence. It is not an airworthiness approval. Substitution decisions remain subject to your organisation’s procurement and engineering approval process and the governing maintenance data (AMM/CMM/SRM/CML/OMAT).
