§ 60.23 

(ii) A description of the corrective 

action taken for each discrepancy, the 
identity of the individual taking the 
action, and the date that action is 
taken is entered in the log. 

(iii) The discrepancy log is kept in a 

form and manner acceptable to the Ad-
ministrator and is kept in or adjacent 
to the FSTD. An electronic log that 
may be accessed by an appropriate ter-
minal or display in or adjacent to the 
FSTD is satisfactory. 

[Docket No. FAA–2002–12461, 71 FR 63426, Oct.

0391, Amdt. 60–4, 81 FR 18218, Mar. 30, 2016] 

§ 60.20

Logging FSTD discrepancies. 

Each instructor, check airman, or 

representative of the Administrator 
conducting training, evaluation, or 
flight experience, and each person con-
ducting the preflight inspection who 
discovers a discrepancy, including any 
missing, malfunctioning, or inoper-
ative components in the FSTD, must 
write or cause to be written a descrip-
tion of that discrepancy into the dis-
crepancy log at the end of the FSTD 
preflight or FSTD use session. 

§ 60.21

Interim qualification of FSTDs 

for new aircraft types or models. 

(a) A sponsor may apply for and the 

NSPM may issue an interim qualifica-
tion level for an FSTD for a new type 
or model of aircraft, even though the 
aircraft manufacturer’s aircraft data 
package is preliminary, if the sponsor 
provides the following to the satisfac-
tion of the NSPM— 

(1) The aircraft manufacturer’s data, 

which consists of at least predicted 
data, validated by a limited set of 
flight test data; 

(2) The aircraft manufacturer’s de-

scription of the prediction method-
ology used to develop the predicted 
data; and 

(3) The QTG test results. 
(b) An FSTD that has been issued in-

terim qualification is deemed to have 
been issued initial qualification unless 
the NSPM rescinds the qualification. 
Interim qualification terminates two 
years after its issuance, unless the 
NSPM determines that specific condi-
tions warrant otherwise. 

(c) Within twelve months of the re-

lease of the final aircraft data package 

by the aircraft manufacturer, but no 
later than two years after the issuance 
of the interim qualification status, the 
sponsor must apply for initial quali-
fication in accordance with § 60.15 based 
on the final aircraft data package ap-
proved by the aircraft manufacturer, 
unless the NSPM determines that spe-
cific conditions warrant otherwise. 

(d) An FSTD with interim qualifica-

tion may be modified only in accord-
ance with § 60.23. 

§ 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 soft-

ware or hardware that are intended to 
impact flight or ground dynamics; 
changes are made that impact perform-
ance or handling characteristics of the 
FSTD (including motion, visual, con-
trol loading, or sound systems for 
those FSTD levels requiring sound 
tests and measurements); or changes 
are made to the MQTG. Changes to the 
MQTG which do not affect required ob-
jective testing results or validation 
data approved during the initial eval-
uation of the FSTD are not considered 
modifications under this section. 

(b) 

FSTD Directive. 

When the FAA de-

termines 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 re-
gardless of the original qualification 
standards applicable to any specific 
FSTD. 

(c) 

Using the modified FSTD. 

The spon-

sor may not use, or allow the use of, or 
offer the use of, the FSTD with the 
proposed modification for flight crew-
member training or evaluation or for 
obtaining flight experience for the 
flight crewmember to meet any re-
quirement 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;
