CHAPTER I--FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATION 
                               (CONTINUED)
 
PART 60_FLIGHT SIMULATION TRAINING DEVICE INITIAL AND CONTINUING 
QUALIFICATION AND USE--Table of Contents
 
Sec.  60.23  Modifications to FSTDs.

    (a) Description of a modification. For the purposes of this part, an 
FSTD is said to have been modified when:
    (1) Equipment or devices intended to simulate aircraft appliances 
are added to or removed from FSTD, which change the Statement of 
Qualification or the MQTG; or
    (2) Changes are made to either software or hardware that are 
intended to impact flight or ground dynamics; changes are made that 
impact performance or handling characteristics of the FSTD (including 
motion, visual, control loading, or sound systems for those FSTD levels 
requiring sound tests and measurements); or changes are made to the 
MQTG.
    (b) FSTD Directive. When the FAA determines that FSTD modification 
is necessary for safety of flight reasons, the sponsor of each affected 
FSTD must ensure that the FSTD is modified according to the FSTD 
Directive regardless of the original qualification standards applicable 
to any specific FSTD.
    (c) Using the modified FSTD. The sponsor may not use, or allow the 
use of, or offer the use of, the FSTD with the proposed modification for 
flight crewmember training or evaluation or for obtaining flight 
experience for the flight crewmember to meet any requirement of this 
chapter unless:
    (1) The sponsor has notified the NSPM and the TPAA of their intent 
to incorporate the proposed modification, and one of the following has 
occurred;
    (i) Twenty-one days have passed since the sponsor notified the NSPM 
and the TPAA of the proposed modification and the sponsor has not 
received any response from either the NSPM or the TPAA;
    (ii) Twenty-one days have passed since the sponsor notified the NSPM 
and the TPAA of the proposed modification and one has approved the 
proposed modification and the other has not responded;
    (iii) Fewer than twenty-one days have passed since the sponsor 
notified the NSPM and the TPAA of the proposed modification and the NSPM 
and TPAA both approve the proposed modification;
    (iv) The sponsor has successfully completed any evaluation the NSPM 
may require in accordance with the standards for an evaluation for 
initial qualification or any part thereof before the modified FSTD is 
placed in service.
    (2) The notification is submitted with the content as, and in a form 
and manner as, specified in the applicable QPS.
    (d) User notification. When a modification is made to an FSTD that 
affects the Statement of Qualification, the sponsor must post an 
addendum to the Statement of Qualification until such time as a 
permanent, updated statement is posted.
    (e) MQTG update. The MQTG must be updated with current objective 
test results in accordance with Sec.  60.15(h) and (i) and appropriate 
objective data in accordance with Sec.  60.13, each time an FSTD is 
modified and an objective test or other MQTG section is affected by the 
modification. If an FSTD Directive is the cause of this update, the 
direction to make the modification and the record of the modification 
completion must be filed in the MQTG.
