[Docket No. FAA-2004-18033; Directorate Identifier 2004-CE-16-AD;
Amendment 39-13828; AD 2004-21-08]
RIN 2120-AA64
Airworthiness Directives; Cessna Aircraft Company Models 190, 195
(L-126A,B,C), 195A, and 195B Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA adopts a new airworthiness directive (AD) for all
Cessna Aircraft Company (Cessna) Models 190, 195 (L-126A,B,C), 195A,
[[Page 62397]]
and 195B airplanes that are equipped with certain inboard aileron hinge
brackets. This AD requires you to repetitively inspect the affected
inboard aileron hinge brackets for cracks or corrosion and replace them
if found cracked or corroded. Replacement with aluminum brackets would
terminate the need for the repetitive inspections. This AD results from
several reports of cracks and corrosion found on the magnesium aileron
hinge brackets. Magnesium is known to be susceptible to corrosion. We
are issuing this AD to detect and correct corrosion damage to the
inboard aileron hinge brackets. Such damage could result in the
brackets cracking across the bearing boss and could lead to the aileron
separating from the airplane with consequent reduced or loss of control
of the airplane.
DATES: This AD becomes effective on November 30, 2004.
As of November 30, 2004, the Director of the Federal Register
approved the incorporation by reference of certain publications listed
in the regulation.

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD? The FAA has received several
reports of cracks and corrosion on part number (P/N) 0322709 and P/N
0322709-1 inboard aileron hinge brackets on Cessna Models 190, 195 (L-
126A,B,C), 195A, and 195B airplanes. These inboard aileron hinge
brackets are constructed of magnesium, which is highly susceptible to
corrosion.
When corrosion starts to develop, the inboard aileron hinge
brackets could crack across the bearing boss.
What is the potential impact if FAA took no action? Cracked or
corroded inboard aileron hinge brackets, if not detected and corrected,
could result in the ailerons separating from the airplane with
consequent reduced or loss of control of the airplane.
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 all Cessna Models 190, 195 (L-
126A,B,C), 195A, and 195B airplanes. This proposal was published in the
Federal Register as a notice of proposed rulemaking (NPRM) on July 15,
2004 (69 FR 42358). The NPRM proposed to require you to repetitively
inspect the affected inboard aileron hinge brackets for cracks or
corrosion and replace them if found cracked or corroded. Replacement
with aluminum brackets would terminate the need for the repetitive
inspections.
Accomplishment of the proposed inspections would be following
Cessna Single Engine Service Bulletin SEB04-1, dated April 26, 2004.
Comments
Was the public invited to comment? We provided the public the
opportunity to participate in developing this AD. The following
presents the comments received on the proposal and FAA's response to
each comment:
Comment Issue No. 1: Allow for Replacement of Inboard Aileron Hinge
Brackets Other Than Cessna Inboard Aileron Hinge Brackets
What is the commenter's concern? Several commenters point out that
the NPRM is confusing. They state that the NPRM preamble states that
you must replace any inboard aileron hinge bracket made from magnesium
with one made from aluminum. However, the actual AD portion of the NPRM
refers to replacing with inboard aileron hinge brackets as specified in
Cessna Single Engine Service Bulletin SEB04-1, dated April 26, 2004.
The commenters believe that this could be confusing in the field as to
whether you can install non-Cessna parts.
Some of these commenters wanted FAA to list the parts that were
approved for installation, including Cessna parts, supplemental type
certificate (STC) parts, and parts manufacturer approval (PMA) parts.
What is FAA's response to the concern? The FAA agrees that the NPRM
is confusing. The intent was to allow installation of any FAA-approved
inboard aileron hinge bracket that is made from aluminum as terminating
action for the repetitive inspections. We will rewrite this portion of
the AD to ensure that the intent is communicated correctly.
However, listing all approved replacement inboard aileron hinge
brackets in the AD is a tedious task and one that could become
burdensome if others wanted the list updated at a later time.
Therefore, we are not including a list of FAA-approved replacement
parts. We will include information that states that FAA-approved
replacement parts may be Cessna parts, STC parts, or PMA parts, etc.
The final rule reflects the change in wording to ensure the
understanding that you may install non-Cessna parts.
Comment Issue No. 2: Refer to the Model 195 Airplanes as Model 195 (L-
126A,B,C) Airplanes
What is the commenter's concern? One commenter recommends that FAA
change reference to the Model 195 airplanes in the applicability to
Model 195 (L-126A,B,C) airplanes. This would coincide with Type
Certificate Data Sheet A-790, Revision 36, dated March 31, 2003.
What is FAA's response to the concern? The FAA agrees and will
change the final rule AD accordingly.
Conclusion
What is FAA's final determination on this issue? We have carefully
reviewed the available data and determined that air safety and the
public interest require adopting the AD as proposed except for the
changes discussed above and minor editorial corrections. We have
determined that these changes and minor corrections:
--Are consistent with 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.
Docket Information
Where can I go to view the docket information? You may view the AD
docket that contains information relating to this subject in person at
the DMS Docket Offices between 9 a.m. and 5 p.m. (eastern standard
time), Monday through Friday, except Federal holidays. The Docket
Office (telephone 1-800-647-5227) is located on the plaza level of the
Department of Transportation NASSIF Building at the street address
stated in ADDRESSES. You may also view the AD docket on the Internet at

http://dms.dot.gov.
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 1,180 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 do this proposed
inspection:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on U.S.
Labor cost Parts cost airplane operators
----------------------------------------------------------------------------------------------------------------
1 workhour x $65 per hour = $65....... No special parts $65 1,180 airplanes x $65 =
necessary for inspection. $76,700.
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements
that would be required based on the results of this proposed
inspection. We have no way of determining the number of airplanes that
may need this replacement:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
6 workhours x $65 per hour = $2,954 $3,344
$390...........................
------------------------------------------------------------------------
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
``Docket No. FAA-2004-18033; Directorate Identifier 2004-CE-16-AD'' in
your request.
