Amending Test and Computation PMA (Parts Manufacturing Approval)

H

HIRFDER

Hello All,

I am having a hard time trying to figure how to put together a package to amend an exiting Test and Comp. PMA. I know the reg have changed recently but can not figure out all the documents that are required. I have read the PMA order in detail.

A check list will be very much appreciated.

By amending do you mean a Major or Minor Change? If it is a minor change than the package would be whatever your ACO requires. If it is a major change than you would want the data that would support the delta change.

Per the regs:


? 21.319 Design changes.
(a) Classification of design changes. (1) A “minor change” to the design of an article produced under a PMA is one that has no appreciable effect on the approval basis.

(2) A “major change” to the design of an article produced under a PMA is any change that is not minor.

(b) Approval of design changes. (1) Minor changes to the basic design of a PMA may be approved using a method acceptable to the FAA.

(2) The PMA holder must obtain FAA approval of any major change before including it in the design of an article produced under a PMA.

I would also recommend reviewing Order 8120.22 Chapter 4 (this replaces Order 8120.2 refereing in the PMA Order 8110.42C)
