RIN 2120-AA64

Airworthiness Directives; Cessna Aircraft Company 150, 152, 172, 177, 180, 182, 185, 188, 206, 207, 210, and 337 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

SUMMARY: This document proposes to adopt a new airworthiness directive (AD) that would apply to Cessna Aircraft Company (Cessna) Model 150, 152, 172, 177, 180, 182, 185, 188, 206, 207, 210, and 337 series airplanes. The proposed AD would require measuring the visible length of standpipe (tube) in the top assembly of the fuel strainer assembly for the correct length, and replacing any fuel strainer assembly that does not have the correct length of standpipe. This action is prompted by reports that the fuel strainer assemblies on the affected airplanes were manufactured with the fuel standpipes incorrectly installed in the assembly housing top. The actions specified by the proposed AD are intended to prevent foreign material from entering the fuel system and engine, which could result in loss of engine power or complete engine stoppage during flight.

DATES: Comments must be received on or before September 21, 1998.

ADDRESSES: Submit comments in triplicate to the Federal Aviation Administration (FAA), Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 97-CE-114-AD, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106. Comments may be inspected at this location between 8 a.m. and 4 p.m., Monday through Friday, holidays excepted.

Service information that applies to the proposed AD may be obtained from The Cessna Aircraft Company, P.O. Box 7706, Wichita, Kansas 67277, telephone: (316) 941-7550, facsimile: (316) 942-9008. This information also may be examined at the Rules Docket at the address above.

FOR FURTHER INFORMATION CONTACT: Paul O. Pendleton, Aerospace Engineer, FAA, Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Wichita, Kansas 67209; telephone: (316) 946-4143; facsimile: (316) 946-4407.

Availability of NPRMs

Any person may obtain a copy of this NPRM by submitting a request to the FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 97-CE-114-AD, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106.

Discussion

The FAA has received reports of problems with certain fuel strainer assemblies, part numbers (P/N) 0756005-2, 0756005-8, or 00756005-9, installed on certain Cessna Model 150, 152, 172, 177, 180, 182, 185, 188, 206, 207, 210, and 337 series airplanes. Cessna reported to the FAA that these fuel strainer assemblies were manufactured with the fuel filter standpipes (P/N 0756007) incorrectly installed in the assembly housing top sometime between December 1996 through September 1997.

This condition may cause a loss of fuel filtration between the fuel tank and the engine fuel metering system, resulting in loss of engine power or complete engine stoppage during flight.

Relevant Service Information

Cessna has issued Service Bulletins SEB97-9, dated November 17, 1997, and MEB97-12, dated November 17, 1997, which specify procedures for measuring the length of the standpipe in the top assembly of the fuel strainer assembly, and replacing any fuel strainer assembly with a standpipe that does not measure a maximum length of 1.68 inches.

The FAA's Determination

After 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 foreign material entering the fuel system and engine, which could result in loss of engine power or complete engine stoppage during flight.

Explanation of the Provisions of the Proposed AD

Since an unsafe condition has been identified that is likely to exist or develop in other Cessna Model 150, 152, 172, 177, 180, 182, 185, 188, 206, 207, 210, and 337 series airplanes of the same type design, the FAA is proposing AD action. The proposed AD would require measuring the fuel strainer assembly standpipe, and replacing any fuel strainer assembly that does not have a standpipe of the correct measurement.

Cost Impact

The FAA estimates that 50,000 airplanes in the U.S. registry would be affected by the proposed AD.

[[Page 39245]]

The proposed measurement is estimated to take 1 workhour per airplane with the average labor rate at approximately $60 an hour. The total cost impact to accomplish the proposed inspection would be $3,000,000 for the U.S. fleet, or $60 per airplane.

The proposed replacement of the fuel strainer assembly is estimated to take 2 workhours per airplane with an average labor rate of approximately $60 per hour. Approximately 300 of the affected parts are thought to have been manufactured. The cost of parts is approximately $180 per airplane. Therefore, based on these figures, the total cost impact to accomplish the proposed replacement, if applicable, on U.S. operators is estimated to be $90,000, or $300 per airplane.

Regulatory Impact

The regulations proposed herein would 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 proposal would not have sufficient federalism implications to warrant the preparation of a Federalism Assessment.

For the reasons discussed above, I certify that this action (1) is not a ``significant regulatory action'' under Executive Order 12866; (2) is not a ``significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated, will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. A copy of the draft regulatory evaluation prepared for this action has been placed in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.

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 (e) 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 12 calendar months after the effective date of this AD, unless already accomplished.

To prevent foreign material from entering the fuel system and engine, which could result in loss of engine power or complete engine stoppage during flight, accomplish the following:

(a) Measure the standpipe in the fuel strainer assembly (tube in the filter strainer top assembly) for a visible maximum length of 1.68 inches in accordance with the ACCOMPLISHMENT INSTRUCTIONS section and Detail A in Cessna Single Engine Service Bulletin (SB) No. SEB97-9, dated November 17, 1997, or Cessna Multi-engine SB No. MEB97-12, dated November 17, 1997, whichever is applicable.

(b) If the standpipe does not measure a maximum length of 1.68 inches, prior to further flight, replace the filter strainer top assembly in accordance with the ACCOMPLISHMENT INSTRUCTIONS section in Cessna Single Engine SB No. SEB97-9, dated November 17, 1997, or Cessna Multi-engine SB No. MEB97-12, dated November 17, 1997, whichever is applicable.

(c) As of the effective date of this AD, no person may install a fuel filter assembly that has a standpipe not measuring a maximum length of 1.68 inches on any of the affected Cessna airplanes.

(d) Special flight permits may be issued in accordance with Secs. 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.

(e) An alternative method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be approved by the Manager, FAA, Wichita Aircraft Certification Office (ACO), 1801 Airport Road, Room 100, 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 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.
