                    Subpart E_Testing In-use Engines

 

Sec.  1048.401  What testing requirements apply to my engines that have 

gone into service?





    (a) If you produce engines that are subject to the requirements of 

this part, you must test them as described in this subpart. This 

generally involves testing engines in the field or removing them for 

measurement in a laboratory.

    (b) We may approve an alternate plan for showing that in-use engines 

comply with the requirements of this part if one of the following is 

true:

    (1) You produce 200 or fewer engines per year in the selected engine 

family.

    (2) Removing the engine from most of the applications for that 

engine family causes significant, irreparable damage to the equipment.

    (3) You identify a unique aspect of your engine applications that 

keeps you from doing the required in-use testing.

    (c) We may void your certificate of conformity for an engine family 

if you do not meet your obligations under this part.

    (d) Independent of your responsibility to test in-use engines, we 

may choose at any time to do our own testing of your in-use engines.

    (e) If in-use testing shows that engines fail to meet emission 

standards or other requirements of this part, we may pursue a recall or 

other remedy as allowed by the Act (see Sec.  1048.415).
