                Subpart D_Testing Production-line Engines
 
Sec. 1051.301  When must I test my production-line vehicles or engines?


    (a) If you certify vehicles to the standards of this part, you must 
test them as described in this subpart. If your vehicle is certified to 
g/kW-hr standards, then test the engine; otherwise, test the vehicle. 
The provisions of this subpart do not apply to small-volume 
manufacturers.
    (b) We may suspend or revoke your certificate of conformity for 
certain engine families if your production-line vehicles or engines do 
not meet the requirements of this part or you do not fulfill your 
obligations under this subpart (see Sec. Sec. 1051.325 and 1051.340).
    (c) Other requirements apply to vehicles and 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 subpart do not 
affect our ability to do selective enforcement audits, as described in 
part 1068 of this chapter. Individual vehicles and 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 vehicles or engines. In your request, you must show us that the 
alternate program gives equal assurance that your products 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. 1051.235(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 vehicle or engine per engine family. If we reduce your 
testing rate, we may limit our approval to a any number of model years. 
In determining whether to approve your request, we may consider the 
number of vehicles or engines that have failed the emission tests.
    (f) We may ask you to make a reasonable number of production-line 
vehicles or engines available for a reasonable time so we can test or 
inspect them for compliance with the requirements of this part.
    (g) The requirements of this subpart do not apply to engine families 
certified under the provisions of Sec. 1051.630.
