Frequently asked questions
How do I pick the correct part?
Start with the manufacturer part number from the illustrated parts catalog or maintenance manual. If an NSN is listed, search that next. Confirm finish, dash number, and engine or airframe applicability before opening an RFQ.
Are these listings in stock or certified?
No. Category pages show PartsPerk-owned observations for sourcing review. Stock, price, trace, and airworthiness stay off the page until a separate publication review.
Can fleet and shop orders be reviewed together?
Yes. Submit quantity, required documents, and need-by date through the sourcing desk. Volume review is human — these pages do not auto-discount.
PartsPerk catalog pages show PartsPerk-owned observations only. They are not live stock, not certification, and not OEM affiliation. Exact PN/NSN identity is for sourcing review; publication and sellability require separate approval.
