AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: 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.

DATES: 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.

ADDRESSES: You may get the service information identified in this AD

SUPPLEMENTARY INFORMATION:

Discussion

    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

[[Page 55944]]

tension. 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.

Conclusion

    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:

----------------------------------------------------------------------------------------------------------------
                                                                       Total cost
              Labor cost                         Parts cost             airplane    Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
1 workhour x $65 per hour = $65......  No parts required............          $65  $65 x 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:

------------------------------------------------------------------------
                                                              Total cost
             Labor cost                    Parts cost            per
                                                               airplane
------------------------------------------------------------------------
1 workhour x $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.

Regulatory Findings

    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.

This packet is not an airworthiness determination and not legal or maintenance advice. AircraftDirectives reproduces official records and condenses their wording for easier reading. It does not decide, certify or imply whether any aircraft, engine, appliance or part is airworthy, compliant, affected by this directive, or eligible for return to service. No inspection, approval, or determination of any kind is performed or implied by this document.

Section 1 is a reading aid, not the rule. It is our own plain-language condensation, written to help a reader find the relevant directive quickly. It is NOT a substitute for the regulation, it may omit conditions, exceptions, compliance times, alternative methods of compliance (AMOCs) and applicability limits, and it has no legal force whatsoever. Only the official text governs. Where Section 1 and Section 2 differ in any respect, Section 2 - and the official source it was retrieved from - controls absolutely.

Responsibility remains with the owner/operator. Under 14 CFR §91.403 and §91.417 the owner or operator is responsible for maintaining airworthiness and for required records; under §39.7 no person may operate a product to which an airworthiness directive applies except in accordance with that directive. Determining applicability to a specific serial number and configuration, and performing or supervising any required action, is the responsibility of the owner/operator and appropriately certificated personnel.

Accuracy and currency. Section 2 was retrieved at the time stamped above and is reproduced without edit; Federal Register material is a work of the United States Government. Directives are amended, corrected and superseded over time, and this sheet is a snapshot, not a live record - it does not update after printing. Re-check the official sources before acting on it. This packet is provided without warranty of any kind, express or implied, including fitness for a particular purpose. We do not sell parts and have no commercial interest in any action a directive may require.
