4.6 Modification of FTDs

4.6.1 Operators must notify the MSP at least 21days prior to making software program or hardware changes which impact flight or ground dynamics. A complete list of these planned changes and identification of proposed updates to the MQTG, must be provided in writing. Operators should maintain a configuration control system to ensure the continued integrity of the device and to account for changes incorporated.

4.6.2 Modifications which impact flight or ground dynamics, systems functions and significant QTG revisions may require a TC evaluation of the FTD.
