FAQ n.104902

Part 21 classification: Is the replacement of each Commercial Off-The-Shelf (COTS) equipment currently at least a minor change?

Answer

There are two possible cases. The replacement of a COTS having the same Part Number (p/n) is considered a maintenance action. Should the p/n be different, it has to be considered as a change.
