## Petition for Exemption

*Docket No.:*                         FAA-2009-0320.                    

*Petitioner:*                         The Boeing Company.                    

*Sections of 14 CFR Affected:*                         §§ 25.301, 25.303, 25.305, 25.307, 25.601, 25.603, 25.613, 25.901(b)(2), 25.901(c), 25.1103(d), 25.1191, and 25.1301(d).                    

*Description of Relief Sought:*                         The petitioner requests an exemption from the requirements for the thrust reverser inner wall structure and operating temperatures, and from the requirements for addressing a pneumatic duct failure condition. The exemption would apply to certain Boeing Model 777-200 and -300 series airplanes equipped with Rolls-Royce RB211 Trent 800 series turbofan engines. The exemption, if granted, would be time-limited to permit the incorporation of incremental design improvements to the thrust reverser and engine as they become available, in order to reduce the risk of a hazardous thrust reverser inner wall failure.
