This document grants in full the petition of Mazda Motor Corporation, (Mazda) in accordance with Sec. 543.9(c)(2) of 49 CFR Part 543, Exemption from the Theft Prevention Standard, for the Mazda CX-9 vehicle line beginning with model year (MY) 2008. This petition is granted because the agency has determined that the antitheft device to be placed on the line as standard equipment is likely to be as effective in reducing and deterring motor vehicle theft as compliance with the parts-marking requirements of the Theft Prevention Standard.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200 and -300 series airplanes. For certain airplanes, this AD requires repetitive inspections for discrepancies of the tube assemblies and insulation of the metered fire extinguisher system and the bleed air duct couplings of the auxiliary power unit (APU) located in the aft cargo compartment, and corrective actions if necessary. For certain other airplanes, this AD requires a one-time inspection for sufficient clearance between the fire extinguishing tube and the APU bleed air duct in the aft cargo compartment, and modification if necessary. This AD also requires an inspection for signs of chafing and to verify sufficient clearance between the fire extinguisher system and the bleed air duct couplings of the APU. This AD results from one report indicating that an operator found a hole in the discharge tube assembly for the metered fire extinguishing system; and another report indicating that an operator found chafing of the fire extinguishing tube against the APU duct that resulted in a crack in the tube. We are issuing this AD to prevent fire extinguishing agent from leaking out of the tube assembly in the aft cargo compartment which, in the event of a fire in the aft cargo compartment, could result in an insufficient concentration of fire extinguishing agent, and consequent inability of the fire extinguishing system to suppress the fire.
