                Subpart D_Testing Production-line Engines
 
Sec. 1048.301  When must I test my production-line engines?


    (a) If you produce engines that are subject the requirements of this 
part, you must test them as described in this subpart.
    (b) We may suspend or revoke your certificate of conformity for 
certain engine families if your production-line engines do not meet the 
requirements of this part or you do not fulfill your obligations under 
this subpart (see Sec. Sec. 1048.325 and 1048.340).
    (c) Other requirements apply to engines that you produce. Other 
regulatory provisions authorize us to suspend, revoke, or void your 
certificate of conformity, or order recalls for engines families without 
regard to whether they have passed these production-line testing 
requirements. The requirements of this part do not affect our ability to 
do selective enforcement audits, as described in part 1068 of this 
chapter. Individual engines in families that pass these production-line 
testing requirements must also conform to all applicable regulations of 
this part and part 1068 of this chapter.
    (d) You may ask to use an alternate program for testing production-
line engines. In your request, you must show us that the alternate 
program gives equal assurance that your production-line engines meet the 
requirements of this part. If we approve your alternate program, we may 
waive some or all of this subpart's requirements.
    (e) If you certify an engine family with carryover emission data, as 
described in Sec. 1048.235(c), and these equivalent engine families 
consistently pass

the production-line testing requirements over the preceding two-year 
period, you may ask for a reduced testing rate for further production-
line testing for that family. The minimum testing rate is one engine per 
engine family. If we reduce your testing rate, we may limit our approval 
to any number of model years. In determining whether to approve your 
request, we may consider the number of engines that have failed the 
emission tests.
    (f) We may ask you to make a reasonable number of production-line 
engines available for a reasonable time so we can test or inspect them 
for compliance with the requirements of this part.
