Are components with defects that are not visible to the naked eye always considered unsalvageable?

Yes, components with non-repairable defects, whether visible or not to the naked eye, should typically be classified as unsalvageable.

Can a component that has been subjected to an unacceptable modification be returned to service if the modification is reversible?

No, the regulation states that components subjected to unacceptable modification or rework that is irreversible should be classified as unsalvageable. If the modification is reversible, it is not covered by this specific criterion, but the component would still need to meet other criteria such as design specifications.

Is a component unsalvageable if it cannot comply with an airworthiness directive that is not yet applicable to it?

No, the regulation refers to 'an applicable airworthiness directive'. If the directive is not applicable, this criterion does not apply.

What documentation-related condition makes a component unsalvageable?

A component is unsalvageable if its maintenance records and/or traceability to the manufacturer cannot be retrieved.

AMC1 145.A.42(a)(iii) Components

Q: What types of components should typically be classified as unsalvageable according to AMC1 145.A.42(a)(iii)?

Components with non-repairable defects (visible or not), components that do not meet design specifications and cannot be brought into conformity, components subjected to unacceptable irreversible modification or rework, parts with mandatory life limitations that have reached/exceeded them or have missing/incomplete records, components whose airworthy condition cannot be restored due to extreme forces/heat/adverse environment, components for which conformity with an applicable airworthiness directive cannot be accomplished, and components for which maintenance records and/or traceability to the manufacturer cannot be retrieved.

Q: What should be done with a part that has a mandatory life limitation but its records are incomplete?

Such a part should typically be classified as unsalvageable, because the regulation lists 'parts with mandatory life limitations that have reached or exceeded these limitations, or have missing or incomplete records' as a type of unsalvageable component.

Q: If a component has been exposed to extreme heat but its airworthy condition can still be restored, is it unsalvageable?

No, the regulation specifies that components whose airworthy condition cannot be restored due to exposure to extreme forces, heat or adverse environmental conditions are unsalvageable. If the condition can be restored, this criterion does not apply.
