How does the repair station perform in-house calibration of the repair station’s equipment and tools?
NOTE: The tool or test equipment used as a standard for performing calibrations cannot be used to perform maintenance after it is calibrated and before being used as an in-house calibration standard.
Manufactures Requirements and Equivalency. Review the part of the RSM/QCM describing the system and procedures used for ensuring the equipment and tools used to maintain articles are those recommended by the articles manufacturer or the equivalent as accepted by the FAA.
Verify that the repair station is using the system and procedures in the RSM/QCM for ensuring the equipment and tools used to maintain articles are those recommended by the article’s manufacturer or the equivalent as accepted by the FAA.
NOTE: The basis of equivalency is the requirement that the article meet the manufacturer’s standards and specifications in all respects regarding tolerances, repeatability, and accuracy.
NOTE: This section is not intended to discuss industry standard tools and equipment (i.e., wrenches, multimeters, sockets, etc.) that are manufactured to a recognized industry standard.
NOTE: Designated Engineering Representatives (DER) may not approve or determine equivalency of tooling and test equipment. Neither the FAA nor a DER may approve equipment and / or test apparatus. The FAA and DERs may only make an acceptance of functional equivalency for special equipment or test apparatus. It is important to emphasize that the burden of demonstrating equivalency is borne by the repair station—not the FAA.
Verify that if the repair station manufactures test and measuring equipment to be used as
an equivalent piece of equipment for one recommended by an articles manufacturer that it meet the calibration standards recommended by the manufacturer of the article being measured or tested. This type of calibration would be expected to be traceable to a standard acceptable to the FAA.
Control, Maintenance and Storage. Review the parts of the RSM/QCM describing the system and procedures for the control, maintenance, use and storage of the equipment and tools used to maintain articles.
The repair station is following its system and procedures in the RSM/QCM for the control, maintenance, use and storage of the equipment and tools used to maintain articles.
The repair station has the equipment and tools necessary to perform the maintenance, preventive maintenance, or alterations under its repair station certificate; and
That equipment and those tools are located on the premises and under the repair station's control when the work is being done.
Also consider any of the following:
Does the repair station have the maintenance and service manuals for all equipment and tools used to perform the maintenance, preventive maintenance, or alterations under its repair station certificate?
Does the repair station fulfill the tool and equipment manufacture’s requirements for control, maintenance, use and storage?
If the repair station does not own the equipment and/or it is not kept at the facility:
