§ 1037.635 Glider kits and glider vehicles.

Except as specified in § 1037.150, the requirements of this section apply beginning January 1, 2017.

(a) Vehicles produced from glider kits and other glider vehicles are subject to the same standards as other new vehicles, including the applicable vehicle standards described in Subpart B of this part. Note that this requirement for the vehicle generally applies even if the engine meets the criteria of paragraph (c)(1) of this section. For engines originally produced before 2017, if you are unable to obtain a fuel map for an engine you may ask to use a default map, consistent with good engineering judgment.

(b) Section 1037.601(a)(1) disallows the introduction into U.S. commerce of a new tractor or vocational vehicle (including a vehicle assembled from a glider kit) unless it has an engine that is certified to the applicable standards in 40 CFR parts 86 and 1036. Except as specified otherwise in this part, the standards apply for engines used in glider vehicles as follows:

(1) The engine must meet the GHG standards of 40 CFR part 1036 that apply for the engine model year corresponding to the vehicle's date of manufacture. For example, for a vehicle with a 2024 date of manufacture, the engine must meet the GHG standards that apply for model year 2024.
