[Docket No. FAA-2004-18033; Directorate Identifier 2004-CE-16-AD]
RIN 2120-AA64

Airworthiness Directives; Cessna Aircraft Company Models 190,
195, 195A, and 195B Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for all Cessna Aircraft Company (Cessna) Models 190, 195, 195A, and
195B airplanes that are equipped with certain inboard aileron hinge
brackets. This proposed AD would require you to repetitively inspect
the affected inboard aileron hinge brackets for cracks or corrosion and
replace them if found cracked or corroded with brackets that are not
made from magnesium. Replacement would terminate the need for the
repetitive inspections. This proposed AD is the result of 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 proposed 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: We must receive any comments on this proposed AD by September
10, 2004.

AD:

Discussion

What events have caused this proposed 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, 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.
Is there service information that applies to this subject? Cessna
has issued Single Engine Service Bulletin SEB04-1, dated April 26,
2004.
What are the provisions of this service information? The service
bulletin includes procedures for:

--Inspecting the P/N 0322709 and P/N 0322709-1 inboard aileron hinge
brackets for cracks or corrosion; and
--Replacing any bracket found cracked or corroded with a bracket that
is FAA-approved and made from aluminum.

FAA's Determination and Requirements of this Proposed AD

What has FAA decided? We have evaluated all pertinent information
and identified an unsafe condition that is likely to exist or develop
on other products of this same type design. Therefore, we are proposing
AD action.

[[Page 42359]]

What would this proposed AD require? This proposed AD would require
you to repetitively inspect the affected inboard aileron hinge brackets
for cracks or corrosion and replace them if found cracked or corroded
with brackets that are not made from magnesium. Replacement would
terminate the need for the repetitive inspections.
How does the revision to 14 CFR part 39 affect this proposed AD? On
July 10, 2002, we published a new version of 14 CFR part 39 (67 FR
47997, July 22, 2002), which governs 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 would this proposed AD impact? We estimate that
this proposed AD affects 1,180 airplanes in the U.S. registry.
What would be the cost impact of this proposed AD on owners/
operators of the affected airplanes? We estimate the following costs to
accomplish this proposed inspection:

----------------------------------------------------------------------------------------------------------------
Total cost on U.S.
Labor cost Parts cost Total cost per airplane operators
----------------------------------------------------------------------------------------------------------------
1 workhour x $65 per hour = $65 No special parts $65 per airplane............. 1,180 airplanes x $65 =
necessary for $76,700.
inspection.
----------------------------------------------------------------------------------------------------------------

We estimate the following costs to accomplish 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:

----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Total cost per airplane
----------------------------------------------------------------------------------------------------------------
6 workhours x $65 per hour = $390............ $2,954 $3,344 per airplane.
----------------------------------------------------------------------------------------------------------------

Regulatory Findings

Would this proposed AD impact various entities? We have determined
that this proposed AD would not have federalism implications under
Executive Order 13132. This proposed AD would 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.
Would this proposed AD involve a significant rule or regulatory
action? For the reasons discussed above, I certify that this proposed
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 proposed 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 FAA-2004-18033; Directorate Identifier 2004-CE-16-AD'' in
your request.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

Accordingly, under the authority delegated to me by the
Administrator, the Federal Aviation Administration proposes to amend 14
CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

2. The FAA amends Sec. 39.13 by adding the following new
airworthiness directive (AD):

Cessna Aircraft Company: Docket No. FAA-2004-18033; Directorate
Identifier 2004-CE-16-AD.

When Is the Last Date I Can Submit Comments on This Proposed AD?

(a) We must receive comments on this proposed airworthiness
directive (AD) by September 10, 2004.

What Other ADs Are Affected by This Action?

(b) None.

What Airplanes Are Affected by This AD?

(c) This AD affects Models 190, 195, 195A, and 195B airplanes,
all serial numbers, that are:
(1) certificated in any category; and
(2) equipped with at least one part number (P/N) 0322709 or P/N
0322709-1 inboard aileron hinge bracket.

What Is the Unsafe Condition Presented in This AD?

(d) This AD is the result of 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.

What Must I do To Address This Problem?

(e) To address this problem, you must do the following:
