Certain major electronic shops designated by the district commander as CALFAC may be utilized for the repair and calibration of avionics test equipment when that facility is traceable to the National standard and when calibration and repair will not exceed how long?

• A. 2 weeks after receipt
• B. 3 weeks after receipt of equipment
• C. 4 weeks after receipt
• D. 6 weeks after receipt

Answer: (B)

The key concept here is the allowed turnaround time for using CALFAC shops to repair and calibrate avionics test equipment. When a major electronic shop is designated CALFAC by the district commander and the work is traceable to the National standard, the calibration and repair must be completed within a specific window after receipt of the equipment. The correct limit is three weeks.

Why three weeks makes sense: it provides a practical balance between getting essential maintenance done promptly to keep equipment ready for flight operations, and giving the shop enough time to perform proper diagnostics, component replacement if needed, calibration, and verification against national standards. The traceability requirement ensures the calibration results are credible and acceptable for aviation maintenance programs, maintaining consistency and reliability across maintenance facilities.

Why not shorter or longer windows: a two-week window can be too tight for thorough troubleshooting and calibration, risking incomplete work or skipped steps. Longer windows, like four or six weeks, would extend downtime unnecessarily and could disrupt schedules and readiness without adding value in the sense of standardizing the calibration process.
