RIN 2120-AA64


Airworthiness Directives; Cessna Aircraft Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to revise an existing airworthiness directive (AD) 
that applies to all Cessna Aircraft Company (Cessna) Models 190, 195 
(L-126A,B,C), 195A, and 195B airplanes that are equipped with certain 
inboard aileron hinge brackets. The existing AD currently requires you 
to repetitively inspect the affected inboard aileron hinge brackets for 
cracks or corrosion and replace them if cracks or corrosion is found. 
Replacement with aluminum brackets would terminate the need for

[[Page 1156]]

the repetitive inspections. Since we issued AD 2004-21-08, the FAA, in 
recent months, has received reports of confusion between the casting 
number on the aileron hinge bracket and the part number (P/N) called 
out in the AD. This proposed AD would retain the actions of AD 2004-21-
08 while requiring future compliance following a revised service 
bulletin that clarifies the casting numbers and part numbers to be 
inspected. We are proposing this AD to correct the unsafe condition on 
these products.

DATES: We must receive comments on this proposed AD by February 22, 
2013.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2012-
18033; Directorate Identifier 2004-CE-16-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We

receive about this proposed AD.

Discussion

    On October 13, 2004, we issued AD 2004-21-08, amendment 39-13828 
(69 FR 62396, October 26, 2004), for all Cessna Models 190, 195 (L-
126A,B,C), 195A, and 195B airplanes that are equipped with certain 
inboard aileron hinge brackets. That AD requires you to repetitively 
inspect the affected inboard aileron hinge brackets for cracks or 
corrosion and replace them if cracks or corrosion is found. Replacement 
with aluminum brackets would terminate the need for the repetitive 
inspections.
    AD 2004-21-08 (69 FR 62396, October 26, 2004) resulted from several 
reports of cracks and corrosion found on the magnesium aileron hinge 
brackets. Magnesium is known to be susceptible to corrosion. We issued 
AD 2004-21-08 (69 FR 62396, October 26, 2004) 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.

Actions Since Existing AD Was Issued

    Since we issued AD 2004-21-08 (69 FR 62396, October 26, 2004), the 
FAA, in recent months, has received reports of confusion between the 
casting number on the aileron hinge bracket and the P/N called out in 
the AD. Due to this misunderstanding, proper inspections and/or 
replacement of the aileron hinge bracket may not be occurring following 
the AD. In one report, a service center provided an airworthiness 
compliance record stating ``aileron hinge brackets are of a different 
part <greek-i> than those specified in the note.'' However, during a 
later inspection of the bracket, a crack was found through the bearing 
boss.

Relevant Service Information

    We reviewed Cessna Aircraft Company Single Engine Service Bulletin 
SEB04-1, dated April 26, 2004, and Single Engine Service Bulletin 
SEB04-01, Revision 1, dated October 3, 2012. The service information 
describes procedures for:

--Inspecting 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.

    Revision 1 of the service information adds casting numbers for the 
parts to be inspected and clarifies the inspection.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would retain all requirements of AD 2004-21-08 (69 
FR 62396, October 26, 2004) while requiring future compliance following 
a revised service bulletin that clarifies the casting numbers and part 
numbers to be inspected.

Change to Existing AD

    This proposed AD would retain all requirements of AD 2004-21-08 (69 
FR 62396, October 26, 2004). Since AD 2004-21-08 was issued, the AD 
format has been revised, and certain paragraphs have been rearranged. 
As a result, the corresponding paragraph identifiers have changed in 
this proposed AD, as listed in the following table:

                      Revised Paragraph Identifiers
------------------------------------------------------------------------
                                      Corresponding requirement in this
    Requirement in AD 2004-21-08                 proposed AD
------------------------------------------------------------------------
          paragraph (e)(1)                        paragraph (h)
          paragraph (e)(2)                        paragraph (i)
          paragraph (e)(3)                        paragraph (j)
------------------------------------------------------------------------

Costs of Compliance

    We estimate that this proposed AD affects 643 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

     The new requirements of this proposed AD add no additional 
economic burden.
    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of aircraft that might need 
these replacements:

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, Section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    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.
    For the reasons discussed above, I certify that the proposed 
regulation:
    (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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

[[Page 1158]]

(h) Inspect Each P/N 0322709 and P/N 0322709-1 Inboard Aileron Hinge 
Bracket or Any Other Bracket Made From Magnesium for Cracks or 
Corrosion

    Within the next 100 hours time-in-service (TIS) after November 
30, 2004 (the effective date retained from AD 2004-21-08, Amendment 
39-13828 (69 FR 62396, October 26, 2004)), and repetitively 
thereafter at intervals not to exceed 100 hours TIS until each 
bracket is replaced with aluminum, inspect each P/N 0322709 and P/N 
0322709-1 inboard aileron hinge bracket or any other bracket made 
from magnesium for cracks or corrosion.

(i) Replace Any Cracked or Corroded Inboard Aileron Hinge Bracket

    Before further flight after any inspection where any cracked or 
corroded bracket is found, replace any cracked or corroded inboard 
aileron hinge.
    (1) If replacement is with an FAA-approved bracket made from 
magnesium, do the 100-hour TIS interval repetitive inspections as 
required in paragraph (h) of this AD.
    (2) If replacement is with an FAA-approved bracket that is made 
from aluminum, then no further inspections are necessary. These can
