14 CFR Part 39

[Docket No. FAA-2009-1015; Directorate Identifier 2009-CE-039-AD]
RIN 2120-AA64

 
Airworthiness Directives; Piper Aircraft, Inc. PA-28, PA-32, PA-
34 and PA-44 Series 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 Piper Aircraft, Inc. (Piper) PA-28, PA-32, PA-34 and PA-44 
series airplanes. This proposed AD would require an inspection of the 
control wheel shaft for both the pilot and copilot sides and, if 
necessary, replacement of the control wheel shaft. This proposed AD 
results from two field reports of incorrectly assembled control wheel 
shafts. We are proposing this AD to detect and correct any incorrectly 
assembled control wheel shafts. This condition, if left uncorrected, 
could lead to separation of the control wheel shaft, resulting in loss 
of pitch and roll control.

DATES: We must receive comments on this proposed AD by December 29, 
2009.

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

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments regarding this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number, ``FAA-
2009-1015; Directorate Identifier 2009-CE-039-AD'' at the beginning of 
your comments. We specifically invite comments on the overall 
regulatory, economic, environmental, and energy aspects of the proposed 
AD. We will consider all comments received by the closing date and may 
amend the proposed AD in light of those comments.
    We will post all comments we receive, without change, to http://
www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive concerning this proposed AD.

Discussion

    We have received two reports of control wheel shafts that have been 
incorrectly assembled at Piper. The first incident concerned the loss 
of the control wheel on a Piper Model PA-34-220T airplane, where the 
right-hand control wheel shaft and universal joint separated due to a 
misdrilled hole for the threaded taper pin. The second report was of a 
ground inspection on a Piper PA-34-220T airplane that revealed a 
similar situation between the control wheel shaft and the universal 
joint in the left-hand side. Investigation following these reports 
revealed that the control wheel shafts had been incorrectly assembled 
at Piper and holes were misdrilled even though they may visually appear 
acceptable. The hole in the shaft may be too close to the end of the 
shaft, causing a significant reduction in joint strength. Since 
discovery of this problem, Piper has added a step to the manufacturing 
process and also introduced a fixture to ensure proper assembly of the 
control wheel shaft/universal joint.
    This condition, if not corrected, could result in separation of the 
control wheel shaft, resulting in loss of pitch and roll control.

Relevant Service Information

    We have reviewed Piper Aircraft, Inc. Service Bulletin No. 1197A, 
dated September 1, 2009.
    The service information describes procedures for:
     Inspection on both the pilot and copilot control wheel 
columns; and
     If necessary, replacement of the control wheel shaft and 
the universal joint.

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 a mandatory inspection of the control wheel shaft for 
both the pilot and copilot sides. This proposed AD results from two 
field reports of incorrectly assembled control wheel shafts. We are 
proposing this AD to detect and correct any incorrectly assembled 
control wheel shafts. This condition, if left uncorrected, could lead 
to separation of the control wheel shaft, resulting in loss of pitch 
and roll control.

Costs of Compliance

    We estimate that this proposed AD would affect 41,928 airplanes in 
the U.S. registry.
    We estimate the following costs to do the proposed inspection:

[[Page 56139]]

                                                                              Total cost per     Total cost on
                 Labor cost                            Parts cost                airplane        U.S. operators
----------------------------------------------------------------------------------------------------------------
0.5 work-hour x $80 per hour = $40.........  Not applicable...............               $40         $1,677,120
----------------------------------------------------------------------------------------------------------------

     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 airplanes that may need 
this repair/replacement:

------------------------------------------------------------------------
                                                         Total cost per
            Labor cost                  Parts cost          airplane
------------------------------------------------------------------------
16 work-hours x $80 per hour =                  $150             $1,430
 $1,280...........................
------------------------------------------------------------------------

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://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) 647-5527) 
is located at the street address stated in the ADDRESSES section. 
Comments will be available in the AD docket shortly after receipt.

List of Subjects in 14 CFR Part 39
