Does FSC 6140 guarantee part fit or interchangeability?

No. Classification groups supply items — it does not replace engineering review, OEM data, PMA data, repair data, MIL-SPEC callouts, or trace sufficiency.

Does PartsPerk certify airworthiness?

No. We organize sourcing workflows and neutral catalog references — engineering, PMA/AD applicability, paperwork, airworthiness approvals, trace, and suitability must be validated by authorized parties.

Is stock held or shipment guaranteed?

No. Timing, condition, certifications, alternate paths, quantity, inspection, customs, logistics, buyer requirements, seller capabilities, paperwork, conformity, and suitability for application require explicit confirmation.
