No certificate will be issued after December 31 of the model year.
(b) The application must contain all the information required by this part and must not include false or incomplete statements or information (see Sec. 1042.255).
(c) We may ask you to include less information than we specify in this subpart, as long as you maintain all the information required by Sec. 1042.250.
(d) You must use good engineering judgment for all decisions related to your application (see 40 CFR 1068.5).
(e) An authorized representative of your company must approve and sign the application.
(f) See Sec. 1042.255 for provisions describing how we will process your application.
(g) We may require you to deliver your test engines to a facility we designate for our testing (see Sec. 1042.235(c)).
(h) For engines that become new after being placed into service, such as engines installed on imported vessels, we may specify alternate certification provisions consistent with the intent of this part. See the definition of ``new marine engine'' in Sec. 1042.901. [73 FR 37243, June 30, 2008, as amended at 75 FR 23000, Apr. 30, 2010]
