Alternate-path review — find engineering-acceptable substitute parts
When the primary part is unavailable, PartsPerk surfaces alternates that are engineering-acceptable. Approval still belongs to your technical authority — PartsPerk never auto-substitutes.

Documents lined up for the alternate before quote
No interchange or PMA claim made by PartsPerk — engineering approves
Common questions
Does PartsPerk decide whether an alternate substitute is acceptable?
No. Substitution acceptance is determined through approved data and your engineering authority. PartsPerk surfaces candidates and the supporting paperwork — engineering decides.
