2003-09-09 Cessna Aircraft Company: Amendment 39-13138; Docket No. 2002-CE-18-AD; Supersedes AD 2002-09-13, Amendment 39-12746. (a) What airplanes are affected by this AD? This AD affects the following airplane models and serial numbers that are certificated in any category: Model Serial numbers 441 0001 through 0362 and 698 F406 0001 through 0089. (b) Who must comply with this AD? Anyone who wishes to operate any of the airplanes identified in paragraph (a) of this AD must comply with this AD. (c) What problem does this AD address? The actions specified by this AD are intended to detect, correct, and prevent chafing and/or arcing fuel boost pump wiring, which could result in arcing within the wing fuel system. Such a condition could lead to ignition of explosive vapor within the fuel storage system. (d) What actions must I accomplish to address this problem? To address this problem, you must accomplish the following: Actions Compliance Procedures (1) For Model 441 airplanes: Inspect the part number (P/N) 5718106-1 wire harness and fuel boost pump lead wires for chafing or damage. Initially at whichever occurs first, unless already accomplished: Within the next 25 hours time-in-service (TIS) or 60 days after May 31, 2002 (the effective date of AD 2002-09-13): Repetitively thereafter at intervals not to exceed 200 hours TIS. In accordance with Cessna Conquest Service Bulletin No.: CQB02-1, Revision 2, dated October 7, 2002. (2) For Model F406 airplanes: Inspect the P/N 5718106-4 wire harness and fuel boost pump lead wires for chafing or damage. Initially at whichever occurs first, unless already accomplished: Within the next 25 hours TIS after June 24, 2003 (the effective date of this AD) or 60 days after June 24, 2003 (the effective date of this AD): Repetitively thereafter at intervals not to exceed 200 hours TIS. In accordance with Reims/Cessna Caravan Service Bulletin No.: CAB02-8, dated June 3, 2002. (3) If chafingor damage is found during any inspection required in paragraph (d)(1) or (d)(2) of this AD: (i) For the Model 441 airplanes, replace the wire harnesses, repair fuel boost pump lead wires, or replace the fuel boost pump, as applicable. (ii) For the Model F406 airplanes, repair or replace the wire harnesses or lead wires, or fuel boost pump, as applicable. Before further flight after any inspection required in paragraphs (d)(1) and (d)(2) of this AD in which damage is found. If improved design wire harnesses and fuel boost pumps are not installed, continue to inspect as specified in paragraph (d)(1) or (d)(2) of this AD until these improved design parts are installed. For the Model 441 airplanes: In accordance with Cessna Conquest Service Bulletin No.: CQB02-1, Revision 2, dated October 7, 2002. For the Model F406 airplanes: In accordance with Reims/Cessna Caravan Service Bulletin No.: CAB02-8, dated June 3, 2002. (4) Perform the following installations: (i) For the Model441 airplanes: Install improved design fuel boost pump (P/N 1C12-17 or FAA-approved equivalent P/N) and improved design wire harness (P/N 5718106-6 or FAA-approved equivalent P/N). Installing both improved part numbers in each wing tank terminates the repetitive inspection requirements of paragraph (d)(1) of this AD. (ii) For the Model F406 airplanes: Install improved design fuel boost pump (P/N 1C12-17 or FAA-approved equivalent P/N) and improved design wire harness (P/N 406 28 01 or FAA-approved equivalent P/N). Installing both improved part numbers in each wing tank terminates the repetitive inspection requirements of paragraph (d)(2) of this AD. Within the next 400 hours TIS after June 24, 2003 (the effective date of this AD), unless already accomplished. For the Model 441 airplanes: In accordance with Cessna Conquest Service Bulletin No.: CQB02-1, Revision 2, dated October 7, 2002. For the Model F406 airplanes: In accordance with Reims/Cessna Caravan Service Bulletin No.: CAB02-8, dated June 3, 2002. (5) Remove the following warnings for the Model 441 airplanes after compliance with Cessna Conquest Service Bulletin No.: CQB02-1, Revision 2, dated October 7, 2002: (i) "PRIOR TO THE INITIAL INSPECTION: THE AIRPLANE SHOULD NOT BE OPERATED WITH LESS THAN 300 POUNDS OF FUEL IN EACH WING." (ii) "AFTER THE INITIAL INSPECTION: THE AIRPLANE SHOULD NOT BE OPERATED WHENEVER THE LEFT OR RIGHT LOW FUEL ANNUNCIATOR IS ILLUMINATED." As of June 24, 2003 (the effective date of this AD). Not applicable. (6) Only install improved design wire harnesses and fuel boost pumps as specified in paragraphs (d)(4)(i) and (d)(4)(ii) of this AD. As of June 24, 2003 (the effective date of this AD). Not applicable. (e) Can I comply with this AD in any other way?

Submit your request through an FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Wichita ACO. (2) Alternative methods of compliance approved in accordance with AD 2002-09-13, which is superseded by this AD, are approved as alternative methods of compliance for all inspection requirements of this AD. Regardless, you still must comply with the replacement requirements of this AD.
