Airworthiness Directive · Amendment 39-14830 · Cessna Aircraft Company Airplanes
Cessna Aircraft Company Airplanes
This AD applies to Cessna Aircraft Company 750.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Cessna Model 750 airplanes. The existing AD currently requires repetitive inspections for clearance and chafing of an auxiliary power unit (APU) fuel tube assembly in the tail cone area of the airplane, and corrective actions if necessary. For certain airplanes, the existing AD also requires replacing the APU fuel line. This new AD adds airplanes to the applicability and allows operators to modify the APU fuel line by installing new fuel lines, fairleads, and clamping configurations, which is an optional terminating action for the repetitive inspections. This AD results from reports of chafed APU fuel tubes leaking into the tail cone area due to interference between the fuel tube assembly and elevator flight control cables, hydraulic lines, and high-temperature bleed air couplings. We are issuing this AD to detect and correct this interference, which could result in chafing, fuel leaking into an area where ignition sources are present, and possible fire in an area without fire detection or extinguishing provisions. DATES: This AD becomes effective December 6, 2006. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of December 6, 2006. On May 10, 2005 (70 FR 21139, April 25, 2005), the Director of the Federal Register approved the incorporation by reference of Cessna Alert Service Letter ASL750-49-09, Revision 2, dated March 10, 2005; and Cessna Service Bulletin SB750-49-05, Revision 1, dated January 17, 2000. We must receive any comments on this AD by January 22, 2007.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
