Auxiliary or Boost Pumps in 2024

[Learjetter]

One could use the grace in AC 20-62 and use the new pump in place of the old one. Just confirm same form, fit, function and that it’s a PMA’d article.

It would take a mechanic to deem it a minor alteration (logbook entry) or an IA to write it up as a major alteration (Form 337), or even get a field approval from the FSDO, depending on how conservative the owner is and how worried the mechanic is.

Personally, if it was mine, I’d call it a minor and go fly.
