Airworthiness Directives; Cessna Aircraft Company 150 and 152 
Series Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to revise Airworthiness Directive (AD) 2009-10-09, 
which applies to certain Cessna Aircraft Company (Cessna) 150 and 152 
series airplanes. AD 2009-10-09 requires either installing a placard 
prohibiting spins and other acrobatic maneuvers in the airplane or 
replacing the rudder stop, the rudder stop bumper, and the attachment 
hardware with a new rudder stop modification kit and replacing the 
safety wire with jamnuts. Since we issued AD 2009-10-09, we became 
aware of a need to clarify certain model and serial number 
designations, remove the duplicate requirement of replacing the safety 
wire with jamnuts, and clarify the conditional acceptability of using 
Modification Kit part number (P/N) SK152-25 as a terminating action to 
this proposed AD. Consequently, this proposed AD would retain the 
actions currently required in AD 2009-10-09, correct model designation 
for certain serial numbers, remove the duplicate requirement of 
replacing safety wire with jamnuts, and clarify the conditional 
acceptability of using Modification Kit P/N SK152-25 as a terminating 
action to this proposed AD. We are proposing this AD to prevent the 
rudder from traveling past the normal travel limit. Operation in this 
non-certificated control position is unacceptable and could cause 
undesirable consequences, such as contact between the rudder and the 
elevator.

DATES: We must receive comments on this proposed AD by September 28, 
2009.

Discussion

    Investigations of two spin accidents involving Cessna Model 152 
airplanes revealed the rudder was found in the over-travel position 
with the stop plate hooked over the stop bolt heads. After examining 
the accident airplanes and other Cessna Models 150 and 152 airplanes, 
accident investigators determined that, under certain conditions, it is 
possible to jam the rudder past its normal travel limit. The jam occurs 
when the stop plate is forced aft of the stop bolt head. The forward 
edge of the stop plate can then become lodged under the head of the 
stop bolt causing the rudder to jam in this over-travel position. 
Recovery from a spin may not be possible with the rudder jammed beyond 
the normal rudder travel stop limits. This condition caused us to issue 
AD 2009-10-09, Amendment 39-15904 (74 FR 22429, May 13, 2009) on 
certain Cessna 150 and 152 series airplanes. AD 2009-10-09 currently 
requires the following:
     Installing a placard prohibiting spins and other acrobatic 
maneuvers in the airplane; or
     Replacing the rudder stop, the rudder stop bumper, and the 
attachment hardware with a new rudder stop modification kit; and
     Replacing the safety wire with jamnuts.
    Since we issued AD 2009-10-09, we became aware of a need to clarify 
certain model and serial number designations and to remove the 
duplicate requirement to replace safety wire with jamnuts since this 
procedure is already included in the modification kit instructions. We 
also became aware of a need to clarify the conditional acceptability of 
using Modification Kit P/N S152-25 as a terminating action to this 
proposed AD.
    This condition, if not corrected, could cause contact between the 
rudder and the elevator and result in loss of control.

Relevant Service Information

    The service information referenced in AD 2009-10-09 is still 
applicable for this proposed AD.

FAA's Determination and Requirements of the Proposed AD

    We are proposing this AD because we evaluated all information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design. This proposed AD 
would revise AD 2009-10-09 with a new AD that would retain the actions 
currently required in AD 2009-10-09, correct model designation for 
certain serial numbers, remove the duplicate requirement to replace the 
safety wire with jamnuts, and clarify the conditional acceptability of 
using the P/N SK152-25 kit as a terminating action to this proposed AD. 
This proposed AD would require you to use the service information 
described previously to perform these actions.

Costs of Compliance

    We estimate that this AD affects 17,090 airplanes in the U.S. 
registry.
    We estimate the following costs to do the proposed insertion of the 
operational limitation:

----------------------------------------------------------------------------------------------------------------
                                                                             Total cost  per     Total cost on
                 Labor cost                            Parts cost                airplane        U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $80 per hour = $80...........  Not applicable...............               $80         $1,367,200
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do the proposed modification:

----------------------------------------------------------------------------------------------------------------
                                                                              Total cost per     Total cost on
                       Labor cost                            Parts cost          airplane        U.S. operators
----------------------------------------------------------------------------------------------------------------

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

[[Page 41098]]

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); 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 regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket that contains the proposed AD, the 
regulatory evaluation, any comments received, and other information on 
the Internet at http://www.regulations.gov; or in person at the Docket 
Management Facility between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Office (telephone (800) 647-5227) 
is located at the street address stated in the ADDRESSES section. 
Comments will be available in the AD docket shortly after receipt.

    Note: This AD revision clarifies the applicability of AD 2009-
10-09, eliminates a duplicate requirement for replacement of safety 
wire with jamnuts, and clarifies the intent of the conditional 
acceptability of using Modification Kit P/N SK152-25 as a 
terminating requirement to the AD. No further action is required for 
those already in compliance with AD 2009-10-09.

Unsafe Condition

    (d) Aircraft in full conformity with type design can exceed the 
travel limits set by the rudder stops. We are issuing this AD to 
prevent the rudder from traveling past the normal travel limit. 
Operation in this non-certificated control position is unacceptable 
and could cause undesirable consequences, such as contact between 
the rudder and the elevator.

Compliance

    (e) To address this problem, you must do either the actions in 
option 1 or option 2 of this AD, unless already done:

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

    (f) Kit P/Ns SK152-24 and SK152-25, which are listed in SEB01-1, 
were superseded by kit P/Ns SK152-24A and SK152-25A. Cessna has not 
revised the service bulletin to reflect the new P/Ns. The kits P/Ns 
SK152-24 and SK152-25 will automatically be filled with P/Ns SK152-
24A and SK152-25A, respectively.
    (1) The P/N SK152-24 kit does not address the unsafe condition 
because the nutplate in the kit can not be used due to rivet spacing 
on the aft bulkhead. In addition, a note was added to kit P/N SK152-
24A stating ``some airplanes in this serial range may have a forged 
bulkhead installed after leaving the factory. Service Kit SK152-25A 
or later revision must be used to modify these airplanes.'' 
Therefore, kit P/N SK152-24 is not allowed for installation for this 
AD.
    (2) The P/N SK152-25 kit did not address the unsafe condition 
because a washer that was too small, P/N NAS1149FN832P, was included 
in the kit. This error was corrected in the P/N SK152-25A kit. If a 
P/N SK152-25 kit is installed using the correct washer P/N 
NAS1149F0332P (and this information is recorded in the maintenance 
log), credit will be given for installing P/N SK152-25A kit because 
this was the only difference between the kits.
    (3) If you previously installed a kit P/N SK152-24 or a kit P/N 
SK152-25 with washer P/N NAS1149FN832P, and you choose the Option 2 
kit installation to comply with this AD, then kit P/N SK152-24A or 
either kit P/N SK152-25 with washer P/N NAS1149F0332P or kit P/N 
SK152-25A, as applicable, must be installed.
    (4) If a P/N SK152-25 kit was installed prior to this AD and the 
washer P/N used in the installation is unknown (not recorded in the 
maintenance log), and you wish to use Option 2 to comply with this 
AD, the washer installed in place of P/N NAS1149F0332P must be 
replaced with a washer P/N NAS1149F0332P, and this work must be 
recorded in the maintenance log.
