FAA modifies rules for commercial parts use
“Proposed Advisory Circular: Commercial Parts,” along with a change to FAR Part 21 regarding commercial parts, might prove a case of a pound of prevention

“Proposed Advisory Circular: Commercial Parts,” along with a change to FAR Part 21 regarding commercial parts, might prove a case of a pound of prevention providing an ounce of cure.

“The revisions to the Part 21 manufacturing rule that the FAA published on Oct. 16, 2009, included a variety of new rules. One of those changes was a modification to the standards for manufacturing. Under the old standards, only parts that were manufactured for installation in type-certified aircraft were regulated by the FAA. Such parts were required to be made under FAA production approval [PC, PMA, TSOA] or under another recognized exception [such as owner-operator produced parts and standard parts],” said Jason Dickstein, general counsel for the Aviation Suppliers Association (ASA).
