PAGE NUMBER: DOCKET NUMBER: 98-CE-54-AD AMENDMENT: 39-10584 AD NUMBER: 98-12-31 SUBJECT HEADING: Airworthiness Directives; British Aerospace Jetstream Model 3101 Airplanes ACTION: Direct final rule; confirmation of effective date SUMMARY: This action confirms the effective date of Airworthiness Directive (AD) 98-12-31, which applies to certain British Aerospace Jetstream Model 3101 airplanes. AD 98-12-31 requires repositioning the fuel cross feed pipes in the lower center fuselage to give an overall clearance of 2 inches when measuring from the bottom of Frame Station 223. This AD was the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified in this AD are intended to prevent the fuel pipe from fracturing during a wheels up landing because of the positioning of the fuel cross feed pipes, which could result in an airplane fire. DATES: Effective September 10, 1998. ADDRESSES: FOR FURTHER INFORMATION CONTACT: Mr. S.M. Nagarajan, Aerospace Engineer, FAA, Small Airplane Directorate, Aircraft Certification Service, 1201 Walnut, suite 900, Kansas City, Missouri 64106; telephone: (816) 426-6934; facsimile: (816) 426-2169. SUPPLEMENTARY INFORMATION: The FAA published this direct final rule with request for comments in the Federal Register on June 12, 1998 (63 FR 32121). The FAA uses the direct final rulemaking procedure for a non-controversial rule where the FAA anticipates that there will be no adverse public comment. This direct final rule advised the public that no adverse comments were anticipated, and that unless a written adverse comment, or a written notice of intent to submit such an adverse comment, was received within the comment period, the regulation would become effective on September 10, 1998. No adverse comments were received, and thus this notice confirms that this final rule will become effective on that date. REGULATORY TEXT: 98-12-31 BRITISH AEROSPACE (Type Certificate No. A21EU formerly held by Jetstream Aircraft Limited): Amendment 39-10584; Docket No. 98-CE-54-AD. Applicability: Jetstream Model 3101 airplanes, serial numbers 602 through 605, certificated in any category. NOTE 1: 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 (c) 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 within the next 100 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished. To prevent the fuel pipe from fracturing during a wheels up landing because of the positioning of the fuel cross feed pipes, which could result in an airplane fire, accomplish the following: (a) Reposition the fuel cross feed pipes in the lower center fuselage to give an overall clearance of 2 inches when measured from the bottom of Frame Station 223. Accomplish this action in accordance with British Aerospace Jetstream Service Bulletin 28-JM 7161, dated December 19, 1983. (b) 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. (c) An alternative method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be used if approved by the Manager, Small Airplane Directorate, Aircraft Certification Service, 1201 Walnut, suite 900, Kansas City, Missouri 64106. The request shall be forwarded through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, Small Airplane Directorate. NOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Small Airplane Directorate. (d) The repositioning required by this AD shall be done in accordance with British Aerospace Jetstream Service Bulletin 28-JM 7161, dated December 19, 1983. 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.
