Aircraft parts stock: what to confirm before ordering

A useful parts quote answers both what is being offered and what the supplier has actually confirmed. Use a consistent request so competing quotes can be compared.

Ask for a dated stock confirmation

Our suggested RFQ starts with the exact part number and suffix, quantity required, delivery location, and required date. Ask the supplier to state whether the part is physically available, where it is held, whether it is reserved, and how long the quoted availability remains valid. Keep the confirmation date with the quantity.

Keep approval evidence separate from a sales claim

The FAA publishes replacement-parts guidance, PMA resources, and unapproved-parts notifications. Use those resources and the applicable manufacturer data as part of a qualified review. A supplier’s statement of stock does not itself establish eligibility for installation. FAA parts resources.

Label missing information honestly

“Listed; availability unconfirmed” is different from “supplier confirmed at [time].” No listing is different from zero stock. For a quote comparison, leave unknown quantity, documentation, and lead time fields marked “not supplied” and request clarification.

AeroOps can help draft the request. Supplier stock results require connected, reviewed sources; this guide does not claim live inventory access.
