Federal Aviation Administration (FAA), DOT.
The FAA adopts a new airworthiness directive (AD) that will supersede AD 86-26-04, which applies to certain Cessna Aircraft Company (Cessna) 120, 140, 140A, 150, F150, 170, 172, F172, FR172, P172D, 175, 177, 180, 182, 185, A185E, 190, 195, 205, 205A, 206, P206, P206E, TP206A, TU206, TU206E, U206, U206E, 207, T207, 210, T210, 336, 337, and T337 series airplanes. AD 86-26-04 currently requires you to inspect and, if necessary, modify the pilot/co-pilot upper shoulder harness adjusters that have certain Cessna accessory kits incorporated. This AD is the result of reports that additional airplanes have the same unsafe condition and the manufacturer revised the service information to add these airplanes and correct the part number of the shoulder harness adjusters. Consequently, this AD retains the actions of 86-26-04, adds additional airplanes to the applicability section of this AD, and incorporates the revised service information. We are issuing this AD to prevent slippage of the pilot/co-pilot shoulder harness, which could result in failure of the shoulder harness to maintain proper belt length adjustment and tension. Such failure could result in pilot/co-pilot injury.
This AD becomes effective on November 1, 2004.
As of November 1, 2004, the Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation.
You may get the service information identified in this AD from The Cessna Aircraft Company, Product Support P.O. Box 7706, Wichita, Kansas 67277; telephone: (316) 517-5800; facsimile: (316) 942-9006.

What is the background of the subject matter? Cessna designed add-on shoulder harness assembly accessory kits for the pilot/co-pilot seats for certain Cessna airplanes. These shoulder harness assemblies incorporate a retainer spring in the adjuster on the upper and lower shoulder harness. The retainer spring may have been inadvertently installed on the belt friction pin. This installation of the spring in the upper shoulder harness adjuster will not allow the belt webbing to lock in place.
This caused us to issue AD 86-26-04, Amendment 39-5503 (52 FR 520, January 7, 1987). AD 86-26-04 currently requires the following on certain Cessna 120, 140, 140A, 150, F150, 170, 172, F172, FR172, P172D, 175, 177, 180, 182, 185, A185E, 190, 195, 205, 205A, 206, P206, P206E, TP206A, TU206, TU206E, U206, U206E, 207, T207, 210, T210, 336, 337, and T337 series airplanes:
—Inspecting the upper shoulder harness adjuster for the presence of a retainer spring;
—If a retainer spring is found, removing the retainer spring; and
—Stamping out the -401 identification number.
What has happened since AD 86-26-04 to initiate this action? We have received reports that additional airplanes have the same unsafe condition. Cessna has revised the related service information to include these additional airplanes.
Cessna also revised the service information to correct the reference to the part number (P/N) of the shoulder harness adjusters. The P/N is referenced as 44030-401 in Cessna Single Engine Service Bulletin SEB86-8 and Cessna Multi-engine Service Bulletin MEB86-22, both dated November 21, 1986. The correct P/N is 443030-401.
What is the potential impact if FAA took no action? If not corrected, the shoulder harness could fail to maintain proper belt length adjustment and Start Printed Page 55944tension. Such failure could result in pilot/co-pilot injury.
Has FAA taken any action to this point? We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Cessna Models 120, 140, 140A, 150, F150, 170, 172, F172, FR172, P172D, 175, 177, 180, 182, 185, A185E, 190, 195, 206, P206, U206, TP206, TU206, 207, T207, 210, T210, 336, 337, and T337 series airplanes. This proposal was published in the Federal Register as a supplemental notice of proposed rulemaking (NPRM) on February 27, 2004 (69 FR 9277). The supplemental NPRM proposed to supersede AD 86-26-04 with a new AD that would require you to:
—Inspect the upper shoulder harness adjuster for the presence of a retainer spring;
—If a retainer spring is found, remove the retainer spring; and
—Stamp out the -401 identification number.
Was the public invited to comment? The FAA encouraged interested persons to participate in the making of this amendment. The following presents the comment received on the proposal and FAA's response to the comment:
Comment Issue: Clarify Whether Retainer Springs, Part Number (P/N) 443030-401, Used in Cessna Service Kits Are Affected by This AD
What is the commenter's concern? The commenter states that there is confusion about whether retainer springs, P/N 443030-401, used in Cessna service kits are affected by this AD. The commenter states that the service kits are different and unrelated to the shoulder harness assembly accessory kits referenced in the AD. The commenter believes this is confusing and may result in a mechanic cutting the spring on the service kit adjusters in an effort to comply with this AD.
The commenter wants us to put a note in the AD to clarify that Cessna service kits that incorporate the use of P/N 443030-401 are not affected by this AD.
What is FAA's response to the concern? We concur with the commenter and will add a paragraph in the AD for clarification. We will change the final rule AD action based on this comment.
What is FAA's final determination on this issue? We carefully reviewed all available information related to the subject presented above and determined that air safety and the public interest require the adoption of the rule as proposed except for the changes discussed above and minor editorial corrections. We have determined that these changes and minor corrections:
—Provide the intent that was proposed in the NPRM for correcting the unsafe condition; and
—Do not add any additional burden upon the public than was already proposed in the NPRM.
Changes to 14 CFR Part 39—Effect on the AD
How does the revision to 14 CFR part 39 affect this AD? On July 10, 2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs the FAA's AD system. This regulation now includes material that relates to altered products, special flight permits, and alternative methods of compliance. This material previously was included in each individual AD. Since this material is included in 14 CFR part 39, we will not include it in future AD actions.
Costs of Compliance
How many airplanes does this AD impact? We estimate that this AD affects 75,329 airplanes in the U.S. registry.
What is the cost impact of this AD on owners/operators of the affected airplanes? We estimate the following costs to accomplish the inspection:
|Labor cost||Parts cost||Total cost airplane||Total cost on U.S. operators|
|1 workhour × $65 per hour = $65||No parts required||$65||$65 × 75,329 = $4,896,385.|
We estimate the following costs to accomplish any necessary modification that will be required based on the results of this inspection. We have no way of determining the number of airplanes that may need this modification:
|Labor cost||Parts cost||Total cost per airplane|
|1 workhour × $65 per hour = $65||No parts required||$65|
What is the difference between the cost impact of this AD and the cost impact of AD 86-26-04? The difference is the addition of 26 airplanes to the applicability section of this AD. There is no difference in cost to perform the inspection and the modification.
Will this AD impact various entities? We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect 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.
Will this AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this AD:
1. Is not a “significant regulatory action” under Executive Order 12866;
2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
3. 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.
We prepared a summary of the costs to comply with this AD and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include “AD Docket No. 2003-CE-40-AD” in your request.Start List of Subjects
