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,

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.

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.
