Airworthiness Directives; Cessna Aircraft Company Models 150 and 
152 Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Cessna Aircraft Company (Cessna) Models 150 and 152 airplanes. 
This proposed AD would require replacing the rudder stop, rudder stop 
bumper, and attachment hardware with a new rudder stop modification 
kit. This proposed AD also requires replacing the safety wire with 
jamnuts. This proposed AD results from two accidents where the rudder 
was found in the over-travel position with the stop plate hooked over 
the stop bolt heads. We are proposing this AD to prevent the rudder 
from traveling past the normal travel limit and becoming jammed in the 
over-travel position. This condition could result in loss of control.

DATES: We must receive comments on this proposed AD by June 15, 2007.

ADDRESSES: Use one of the following addresses to comment on this 
proposed AD:

the instructions for sending your comments electronically.

arguments regarding this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number, ``FAA-
2007-27747; Directorate Identifier 2007-CE-030-AD'' at the beginning of

regulatory, economic, environmental, and energy aspects of the proposed 
AD. We will consider all comments received by the closing date and may

Discussion

    This AD results from two spin accidents involving Cessna Model 152 
airplanes where the rudder was found in the over-travel position with 
the stop plate hooked over the stop bolt heads.
    In the first accident, which occurred in Canada, a flight 
instructor and student pilot were unable to recover after performing a 
spin maneuver. When the airplane was inspected, the rudder was found 
jammed.
    In the second accident the rudder bumper was found to be installed 
incorrectly, which resulted in a rudder jam during an attempted spin 
recovery.
    Upon recovery of the airplanes after the accidents, both accident 
airplanes had their rudder stop plates hooked over the stop bolts. 
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, if not corrected, could result in loss of control.

Relevant Service Information

    We have reviewed the following Cessna Aircraft Company service 
information, dated January 22, 2001:
     Service Bulletin SEB01-1;
     Service Kit SK152-25; and
     Service Kit SK152-24.
    The service information describes procedures for replacing the 
rudder stop, rudder stop bumper, and attachment hardware with a new 
rudder stop modification kit. The service information also describes 
the procedure for replacing the safety wire with jamnuts.

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 require replacing the rudder stop, rudder stop bumper, and 
attachment hardware with a new rudder stop modification kit. This 
proposed AD also requires replacing the safety wire with jamnuts.

Costs of Compliance

    We estimate that this proposed AD would affect 18,670 airplanes in 
the U.S. registry.
    We estimate the following costs to do the proposed modification:

----------------------------------------------------------------------------------------------------------------
                                                                                 Total cost per   Total cost on
                          Labor cost                              Parts cost        airplane      U.S. operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $80 per hour = $320...........................             $60             $380       $7,094,600
----------------------------------------------------------------------------------------------------------------

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); 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://dms.dot.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.

the over-travel position. This condition could result in loss of 
control.
