AD 97-01-13 ACTIVE

This amendment adopts a new airworthiness directive (AD) that applies to Cessna Aircraft Company (Cessna) 100, 200, 300, and 400 series airplanes. This action requires checking the airplane maintenance records for any fuel, oil, or hydraulic hose, Cessna part number (P/N) S51-10, replaced between March 1995 and February 3, 1997 (the effective date of this AD); immediately checking any of these hoses for a diagonal or spiral external reinforcement wrap; and immediately replacing any of these hoses that have a diagonal or spiral external reinforcement wrap with one that has a crisscross external reinforcement wrap. This action was prompted by reports of operators experiencing a loss of engine power because of low fuel feed, in addition to Cessna discovering that the rubber hose installed at the factory on certain Cessna Models 208 and 208B airplanes was defective. The Cessna P/N S51-10 rubber hose is utilized on fuel, oil, and hydraulic hoses on the affected airplanes. Theactions specified by this AD are intended to prevent fuel, oil, or hydraulic systems failure caused by a collapsed hose.

Discussion\n\tThe FAA has recently received several incident reports of fuel flow blockage to the engines of certain Cessna 208 series airplanes. Examination of the Cessna part number (P/N) S51-10 rubber hoses installed on these airplanes revealed a deterioration to the point of delamination of the inner tube from the external wrap. This rubber hose is utilized on fuel, oil, and hydraulic hoses on Cessna 100, 200, 300, and 400 series airplanes. This kind of deterioration eventually causes the rubber hose to collapse, which could result in failure of the fuel, oil, or hydraulic systems.\n\n\tFurther investigation revealed this particular rubber hose was manufactured by Buckeye Rubber Products Company in January 1995, and Cessna purchased 300 feet of this hose for factory installation on certain Cessna Models 208 and 208B airplanes between March 1995 and June 1995. The remaining portion of hose was distributed in March 1995 as replacement hose. With this in mind, the Cessna P/N S51-10 hose could be installed by field approval on any Cessna 100, 200, 300, and 400 series airplanes, as well as at manufacture on certain Cessna Models 208 and 208B airplanes.\n\nRelative Service Information\n\tCessna has issued the service bulletins presented below, which include ACCOMPLISHMENT INSTRUCTIONS for (1) checking for the installation of fuel, oil, and hydraulic hoses, Cessna P/N S51-10, with a diagonal or spiral external reinforcement wrap, and (2) replacing any of these hoses that have a diagonal or spiral external reinforcement wrap with one that has a crisscross external reinforcement wrap:\n\n\tREIMS/CESSNA Service Bulletin (SB) CAB96-21, dated October 18, 1996; Model Affected: F406\n\n\tCessna Aircraft Company SB CQB96-3, dated October 18, 1996; Model Affected: 425\n\n\tCessna Aircraft Company SB SEB96-15, dated October 18, 1996; Models Affected: 150, 150A, 150B, 150C, 150D, 150E, 150F, 150G, 150H, 150J, 150K, 150L, 150M, A150K, A150L, A150M, F150F, F150G, F150H, F150J, F150K, F150L, F150M, FA150K, FA150L, FRA150L, FRA150M, 152, A152, F152, FA152, 172, 172A, 172B, 172C, 172D, 172E, 172F, 172G, 172H, 172I, 172K, 172L, 172M, 172N, 172P, 172Q, FP172, F172D, F172E, F172F, F172G, F172H, F172K, F172L, F172M, F172N, F172P, FR172E, FR172F, FR172G, FR172H, FR172J, FR172K, 175, 175A, 175B, 175C, P172D, R172E(T41), R172F(T41), R172G(T41), R172H(T41), R172J, R172K, 172RG, 177, 177A, 177B, 177RG, F177RG, 180, 180A, 180B, 180C, 180D, 180E, 180F, 180G, 180H, 180J, 180K, 182, 182A, 182B, 182C, 182D, 182E, 182F, 182G, 182H, 182J, 182K, 182L, 182M, 182N, 182P, 182Q, 182R, F182P, F182Q, FR182, R182, T182, TR182, 185, 185A, 185B, 185C, 185D, 185E, A185E, A185F, 188, 188A, 188B, A188, A188A, A188B, T188C, 206, U206, U206A, U206B, U206C, U206D, U206E, U206F, U206G, TU206A, TU206B, TU206C, TU206D, TU206E, TU206F, TU206G, P206A, P206B, P206C, P206D, P206E, TP206, TP206A, TP206B, TP206C, TP206D, TP206E, 207, 207A, T207, T207A, 210, 210-5 (205), 210-5A (205A), 210A, 210B, 210C, 210D, 210E, 210F, 210G, 210H, 210J, 210K, 210L, 210M, 210N, 210R, P210N, P210R, and T210F.\n\n\tCessna Aircraft Company SB CAB96-15, Revision 1, October 18, 1996; Models Affected: 208 and 208B.\n\n\tCessna Aircraft Company SB MEB96-10, dated October 18, 1996; Models Affected: T303, 310P, 310Q, 310R, T310P, 310Q, 310R, 335, 336, 337, 337A, 337B, 337C, 337D, 337E, 337F, 337G, 337H, F337E, F337F, F337G, F337H, FT337E, FT337F, FT337GP, FT337HP, FTB337, T337B, T337C, T337D, T337E, T337F, T337G, T337H, T337H-SP, M337B, P337H, 340, 340A, 401, 401A, 401B, 402, 402A, 402B, 402C, 404, 411, 411A, 414, 414A, 421, 421A, 421B, and 421C.\n\nThe FAA's Determination\n\tAfter examining the circumstances and reviewing all available information related to the incidents described above, including the referenced service information, the FAA has determined that AD action should be taken to prevent fuel, oil, or hydraulic systems failure caused by a collapsed hose.\n\nExplanation of the Provisions of This AD\n\tSince an unsafe condition has been identified that is likely to exist or develop in other Cessna 100, 200, 300, and 400 series airplanes of the same type design, the FAA is issuing an AD. This AD requires checking the airplane maintenance records for any fuel, oil, or hydraulic hose, Cessna part number (P/N) S51-10, replaced between March 1995 and February 3, 1997 (the effective date of this AD); immediately checking any of these hoses for a diagonal or spiral external reinforcement wrap; and immediately replacing any of these hoses that have a diagonal or spiral external reinforcement wrap with one that has a crisscross external reinforcement wrap. Accomplishment of the hose check and replacement is required in accordance with the service bulletins referenced previously.\n\nDetermination of the Effective Date of the AD\n\tSince a situation exists that requires the immediate adoption of this regulation, it is found that notice and opportunity for public prior comment hereon are impracticable, and that good cause exists for making this amendment effective in less than 30 days.\n\nCompliance Time of This AD\n\tThe compliance time of this AD is presented in calendar time and hours time-in-service (TIS). Delamination of the rubber hose inner tubing and separation of the inner tube from the external wrap is caused by an error in manufacturing. This condition can develop regardless of whether the airplane is in flight. The breakdown of the hose may not be noticed initially, but as the hose continues to erode, collapse is inevitable, which could result in fuel, oil, or hydraulic systems failure. For these reasons, the FAA is requiring a compliance time of specific hours TIS and calendar time (the prevalent one being that which occurs first).\n\nComments Invited\n\tAlthough this action is in the form of a final rule that involves requirements affecting immediate flight safety and, thus, was not preceded by notice and opportunity to comment,comments are invited on this rule. Interested persons are invited to comment on this rule by submitting such written data, views, or arguments as they may desire. Communications should identify the Rules Docket number and be submitted in triplicate to the address specified above. All communications received on or before the closing date for comments will be considered, and this rule may be amended in light of the comments received. Factual information that supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether additional rulemaking action would be needed.\n\n\tComments are specifically invited on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify the rule. All comments submitted will be available, both before and after the closing date for comments, in the Rules Docket for examination by interested persons. A report that summarizeseach FAA-public contact concerned with the substance of this AD will be filed in the Rules Docket.\n\n\tCommenters wishing the FAA to acknowledge receipt of their comments submitted in response to this notice must submit a self-addressed, stamped postcard on which the following statement is made: "Comments to Docket No. 96-CE-46-AD." The postcard will be date stamped and returned to the commenter.\n\nRegulatory Impact\n\tThe regulations adopted herein will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. Therefore, in accordance with Executive Order 12612, it is determined that this final rule does not have sufficient federalism implications to warrant the preparation of a Federalism Assessment.\n\n\tThe FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and is not a significant regulatory action under Executive Order 12866. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the Rules Docket (otherwise, an evaluation is not required). A copy of it, if filed, may be obtained from the Rules Docket.\n\nList of Subjects in 14 CFR Part 39\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.\n\nAdoption of the Amendment\n\tAccordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:\n\nPART 39 - AIRWORTHINESS DIRECTIVES\n\t1. The authority citation for part 39 continues to read as follows:\n\tAuthority: 49 USC 106(g), 40113, 44701.\n§ 39.13 (Amended)\n\t2. Section 39.13 is amended by adding a new airworthiness directive (AD) to read as follows:
