Applicability: Model 650 airplanes, having serial numbers 650-0174 through 650-0241 inclusive, 650-7001 through 650-7006 inclusive, and 650-7008 through 650-7076 inclusive, certificated in any category.

NOTE 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been otherwise modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Compliance: Required as indicated, unless accomplished previously.

To prevent electrical arcing of the alternating current wire and consequent fire hazard, accomplish the following:

(1) Perform a visual inspection to detect discrepancies (i.e., improper clearance, wear, and damage) of the wire bundle assembly from point 1 to point 2, in accordance with the service bulletin. If any discrepancy is detected, prior to further flight, replace the wire bundle assembly with a new wire bundle assembly or install a spiral wrap, as applicable, in accordance with the service bulletin.

(2) Perform a visual inspection to detect discrepancies (i.e., chafing, rubbing, nicks, scratches, and burn marks) of the hydraulic pump suction line in the area above the baggage compartment, in accordance with the service bulletin. If any discrepancy is detected, prior to further flight, repair it in accordance with the service bulletin.

(3) Modify the supports for the wire bundle cable assembly and the supports for the hydraulic pump suction line in accordance with the service bulletin.

(b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Wichita Aircraft Certification Office (ACO), FAA, Small Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Wichita ACO.

NOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Wichita ACO.

(c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished.

(d) The inspections and modification shall be done in accordance with Cessna Service Bulletin SB650-24-57, dated May 15, 1997. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be obtained from Cessna Aircraft Co., P.O.
