ARSA Seeks Response on Calibration of MTE

ARSA recently sent a letter to FAA about  confusion that exists regarding the calibration of measuring and test equipment (MTE). The uncertainty stems from a number of local FAA inspectors who contend that repair stations calibrating their own equipment may only use criteria and procedures developed by the manufacturer of the equipment.

The association is asking for a response from the FAA that reinforces its guidance in AC 145-9 and Order 8900.1. Specifically, a reply to its letter stating that the techniques and procedures used for calibrating MTE include both industry standards and those provided by the manufacturer of the equipment.

A copy of ARSA’s letter may be found here.
