INTERCHANGEABLE AND REPLACEABLE (I&R) PLAN
An I&R plan is a written description of the manufacturing, tooling and quality acceptance
plans necessary to achieve the engineering I&R requirements. I&R plans consist of a
primary item and its corresponding secondary item(s). I&R plans are normally developed
and/or require approval by the Customer. The I&R plan shall be updated and approved
prior to any changes made to the manufacturing process, engineering, tooling, or quality
plans. Any deviation from an approved I&R plan shall be requested in writing for review
and Customer approval prior to implementation.
INTERCHANGEABLE
Interchangeable items are defined by engineering and/or manufacturing operations and
are fabricated with the aid of control media tools. Interchangeable items are capable of
being readily installed, removed, or replaced without alteration, misalignment, or damage
to items being installed or adjoining items or structure.
JIG
