Compliance : Required as indicated in FAA AD 98-15-13

Amendment 39-10664; Docket No. 97-CE-92-AD.

Applicability: The following airplane models and serial numbers, certificated in any category.

NOTE 1: The airplane models and serial numbers listed in this AD take precedence over those listed in Raytheon Aircraft Service Bulletin No. 2718, Rev. 1, Issued: January, 1997; Revised: June, 1997.

NOTE 2: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been 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 (f) 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 in the body of this, unless already accomplished.

To prevent fuel flow interruption, which if not corrected, could lead to uncommanded loss of engine power and loss of control of the airplane, accomplish the following:

(a) For airplanes manufactured prior to January 1, 1994: within the next 200 hours time-in-service (TIS) after the effective date of this AD, check the airplane maintenance records for any MIL-H-6000B fuel hose replacement from January 1, 1994, up to and including the effective date of this AD. Accomplish the following in accordance with PART II of the ACCOMPLISHMENT INSTRUCTIONS section in Raytheon Aircraft Mandatory Service Bulletin (SB) No. 2718, Rev. 1, Issued: January, 1997; Revised: June, 1997:

(1) If the airplane records show that an MIL-H-6000B fuel hose has been replaced, prior to further flight, inspect the airplane fuel hoses for a 3/8-inch-wide red or orange-red, length-wise stripe, with the manufacturer’s code, 94519, printed periodically along the line in red letters on one side. The hoses have a spiral or diagonal outer wrap with a fabric-type texture on the rubber surface.

(2) Prior to further flight, replace any fuel hose that matches the description in paragraph (a)(1) of this AD with an FAA-approved MIL-H-6000B fuel hose that has a criss-cross or braided external wrap.

(b) An owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) can accomplish paragraph (a) required by this AD, and must enter the accomplished action into the aircraft records showing compliance with this AD in accordance with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).

(c) For Raytheon Models C90A, B200, and B300 airplanes that were manufactured on January 1, 1994, and after: within the next 200 hours time-in-service (TIS) after the effective date of this AD, replace the MIL-H-6000B fuel hoses in accordance with PART I of the ACCOMPLISHMENT INSTRUCTIONS section of Raytheon SB No. 2718, Rev. 1, Issued: January, 1997, Revised: June, 1997.

(d) As of the effective date of this AD, no person shall install a rubber fuel hose having spiral or diagonal external wrap with a 3/8-inch-wide red or orange-red, length-wise stripe running down the side of the hose, with the manufacturer’s code, 94519, printed periodically along the line in red letters on any of the affected airplanes.

(e) 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.

(f) An alternative method of compliance or adjustment of the compliance times that provides an equivalent level of safety may be approved by the Manager, Wichita Aircraft Certification Office, Room 100, 1801 Airport Rd., Wichita, Kansas 67209. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Wichita Aircraft Certification Office.

NOTE 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Wichita Aircraft Certification Office.

(g)The inspection and replacement required by this AD shall be done in accordance with Raytheon Aircraft Mandatory Service Bulletin No. 2718, Rev. 1, Issued:

January, 1997; Revised: June, 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 to Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201-0085.
