(a) This section applies to any private entity operating OTRBs that takes one of the following actions:

(1) On or after the date on which this subpart applies to the entity, it remanufactures an OTRB so as to extend its useful life for five years or more or makes a solicitation for such remanufacturing; or

(2) Purchases or leases an OTRB which has been remanufactured so as to extend its useful life for five years or more, where the purchase or lease occurs after the date on which this subpart applies to the entity and during the period in which the useful life of the vehicle is extended.

(b) In any situation in which this subpart requires an entity purchasing or leasing a new OTRB to purchase or lease an accessible OTRB, OTRBs acquired through the actions listed in paragraph (a) of this section shall, to the maximum extent feasible, be readily accessible to and usable by individuals with disabilities, including individuals who use wheelchairs.

(c) For purposes of this section, it shall be considered feasible to remanufacture an OTRB so as to be readily accessible to and usable by individuals with disabilities, including individuals who use wheelchairs, unless an engineering analysis demonstrates that including accessibility features required by this part would have a significant adverse effect on the structural integrity of the vehicle.
