14 CFR Part 39

[Docket No. FAA-2012-0275; Directorate Identifier 2012-CE-009-AD; 
Amendment 39-16981; AD 2012-05-09]
RIN 2120-AA64


Airworthiness Directives; Mooney Aviation Company, Inc. (Mooney) 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are issuing an airworthiness directive (AD) for all Mooney 
Aviation Company, Inc. (Mooney) Models M20B, M20C, M20D, M20E, M20F, 
M20G, M20J, M20K, M20L, M20M, M20R, M20S, and M20TN airplanes that 
supersedes an existing AD that is applicable to certain Model M20R and 
M20TN airplanes. The existing AD currently requires inspecting the tail 
pitch trim assembly for correct positioning and proper attachment and 
inspecting the Huck Bolt fasteners for proper security with repair as 
necessary for certain Models M20R and M20TN. That AD also requires 
sending the inspection results to the FAA and Mooney. This AD retains 
all of the actions, except the reporting requirement from the previous 
AD and adds airplane models to the applicability. This AD was prompted 
by a report of an incident on a Mooney Model M20TN airplane regarding 
failure of the tail pitch trim assembly, which could result in loss of 
control. We are issuing this AD to correct the unsafe condition on 
these products.

DATES: This AD is effective March 20, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of March 20, 
2012.

SUPPLEMENTARY INFORMATION: 

Discussion

    On February 16, 2012, we issued AD 2012-03-52, amendment 39-16958 
(77 FR 12179, February 29, 2012), for certain Mooney Aviation Company, 
Inc. (Mooney) Models M20R and M20TN airplanes. That AD requires 
inspecting the tail pitch trim assembly for correct positioning and 
proper attachment and inspecting the Huck Bolt fasteners for proper 
security with repair as necessary. That AD also requires sending the 
inspection results to the FAA and Mooney. That AD resulted from a 
report of an incident on a Mooney Model M20TN airplane regarding 
failure of the tail pitch trim assembly, which could result in loss of 
control. We issued that AD to detect incorrect positioning and improper 
attachment of the trim fitting, hinge, and filler plate of the tail 
pitch trim assembly and to verify security of the attaching Huck Bolt 
fasteners, which could lead to failure of the tail pitch trim assembly 
with consequent loss of pitch control.

Actions Since AD Was Issued

    Since we issued AD 2012-03-52 (77 FR 12179, February 29, 2012), we 
received a report from an owner/operator of a Model M20J airplane who 
had the airplane inspected and found the same unsafe condition. Since 
the Models M20B, M20C, M20D, M20E, M20F, M20G, M20J, M20K, M20L, M20M, 
and M20S airplanes have the same type design as the Models M20R and 
M20TN airplanes, we determined that these airplanes should be added to 
the applicability of the AD to ensure that the unsafe condition is 
addressed on all airplanes of the type design.
    Also, Mooney published new service information that includes the 
expanded airplane applicability and instructions for installing 
replacement fasteners, if necessary.

Relevant Service Information

    We reviewed Mooney Aviation Company, Inc. Service Bulletin No. M20-
313A, dated February 29, 2012; and Service Bulletin No. M20-314A, dated 
February 29, 2012. The service information describes procedures for 
inspecting the tail pitch trim assembly for correct positioning and 
proper attachment, inspecting the Huck Bolt fasteners for proper 
security, and installing replacement fasteners, if necessary.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information

[[Page 16136]]

and determined the unsafe condition described previously is likely to 
exist or develop in other products of the same type design.

AD Requirements

    This AD requires inspecting the trim fitting, hinge, and filler 
plate of the tail pitch trim assembly for correct positioning and 
proper attachment, and inspecting the Huck Bolt fasteners for proper 
security on all Mooney Models M20B, M20C, M20D, M20E, M20F, M20G, M20J, 
M20K, M20L, M20M, M20R, M20S, and M20TN airplanes. If incorrect 
positioning or improper/loose attachment is found, this AD requires 
installing replacement parts and fasteners. These are the same actions 
currently required by AD 2012-03-52 for certain Mooney Models M20R and 
M20TN airplanes, except the reporting requirement is no longer 
required.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
failure of the tail pitch trim assembly could result in loss of 
control. Therefore, we find that notice and opportunity for prior 
public comment are impracticable and that good cause exists for making 
this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
the docket number FAA-2012-0275 and directorate identifier 2012-CE-009-
AD at the beginning of your comments. We specifically invite comments 
on the overall regulatory, economic, environmental, and energy aspects 
of this AD. We will consider all comments received by the closing date 
and may amend this 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 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 6,630 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                      Cost per     Cost on U.S.
              Action                        Labor cost              Parts cost         product      operators
----------------------------------------------------------------------------------------------------------------
Inspection of the trim fitting,     1 work-hour x $85 per      Not applicable......        $85         $563,550
 hinge, and filler plate of the      hour = $85.
 tail pitch trim assembly, and
 security of the Huck Bolt
 fasteners.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacement of 
the parts and Huck Bolt fasteners that will be required based on the 
results of the inspection. We have no way of determining the number of 
aircraft that might need this repair:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                      Cost per
                    Action                                   Labor cost                Parts cost      product
----------------------------------------------------------------------------------------------------------------
Installation of replacement parts and          16 work-hours x $85 per hour = $1,360         $302        $1,662
 fasteners, including repair of an
 incorrectly positioned and/or improperly
 attached tail pitch trim assembly.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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 this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.
