Federal Motor Vehicle Safety Standards; Air Brake Systems Control Line Pressure Balance

摘要

This notice denies a petition submitted by Mr. Robert Crail requesting the agency to reconsider a final rule that added control line pressure balance requirements to the pneumatic timing requirements applicable to air brake systems. Mr. Crail's petition was based on his allegations that NHTSA had not adequately considered the added costs to trailer manufacturers imposed by the rulemaking, including the hardware costs to achieve compliance with the new control line pressure balance requirements and the costs associated with certifying compliance with those requirements. In response to this petition, the agency has reexamined the final rule's evaluation of additional costs for this requirement and again concludes that those additional costs are not excessive or unreasonable. Therefore, Mr. Crail's petition is denied.
