Calibration/Record. Review the part of the RSM/QCM describing the system and procedures used for calibrating MTE.
The PI will verify.
The repair station is calibrating MTE, in accordance with the intervals, the system and procedures described in the RSM/QCM
All MTE is calibrated and traceable to a standard acceptable to the FAA to include those recommended by the manufacturer and the National Institute of Standards and Technology (NIST) or other national authority
NOTE: The 14 CFR part 145 rules states that tooling are calibrated to a standard acceptable to the Administrator. Those standards may be derived from the National Institute of Standards and Technology (NIST), or to a standard provided by the equipment manufacturer. International agreements may also be accepted as a means of compliance. A list of international agreements referred to as Memorandum of Understanding (MOU) or Mutual Recognition Agreement (MRA) may be accessed from the NIST Web site (). Also, the National Voluntary Laboratory Accreditation Program (NVLAP) provides third-party accreditation to testing and calibration laboratories. NVLAP accreditation programs are established in response to Congressional mandates, administrative actions by the Federal Government, or from requests by private-sector organizations. NVLAP is in full conformance with the standards of the International Organization for Standardization (ISO) and the International Electro-technical Commission (IEC), including ISO/IEC 17025 and Guide 58. NVLAP identifies its accredited laboratories in a published directory, NIST Special Publication 810, which is published on the NIST Web site. Additionally, for foreign equipment, the standard of the country of manufacture may be used if
approved by the Administrator. An Exemption Authorization is required if a repair station uses equipment of a foreign manufacturer and the method of calibration it will use is not addressed through a MOU or MRA, or the FAA inspector cannot obtain the validity of the Calibration Laboratory. Exemption authorizations are granted through the issuance of an exemption IAW 14 CFR parts 11 guidance. Currently, exemptions of this type are issued for a 2-year period and can be renewed if requested by the repair station.
Also consider the following:
Does the repair station determine calibration status of new tools or equipment before they are put into service?
How and when is MTE recalled for calibration?
Does the calibration and tracking system include employee‑owned MTE?
How does the repair station establish calibration intervals?
Does the repair station maintain a list of all calibrated equipment by name, model or part number, serial number, date of calibration, and next calibration due date?
Are calibration records maintained for at least 2 years?
Is MTE identified to prevent the inadvertent use of non-calibrated equipment in the maintenance process? The identification usually includes the serial number or other identification, date of last calibration, date calibration is due, and the name or initials of the person who performed the calibration?
Are equipment and tools, that are not used to make airworthiness determinations, identified?
