SUPPLEMENTARY INFORMATION:

Discussion

    The FAA has received recent reports of misrouted emergency gear 
extension cables on Piper Models PA-44-180 and PA-44-180T airplanes. 
This condition spans many years beginning in 2007 where one of the 
airplanes experienced the left-side copilot rudder pedal snagging on 
the emergency landing gear extension cable during taxi maneuvers. Piper 
Modification Kit 884333 (Piper Service Bulletin No. 1188, dated April 
14, 2008) provides the parts and instructions to reroute the cable away 
from the pedal for airplanes in service and a production change was 
made to duplicate the kit configuration.
    In 2009, there was a quality escape on the production aircraft 
(after issuance of SB 1188), which was addressed with Piper Service 
Bulletin No. 1213, dated March 24, 2010. Recently, there has been 
another quality escape reported of the cable being routed incorrectly, 
resulting in the issuance of Piper Service Bulletin 1213A, dated 
October 23, 2015 to more fully address the incorrect routing of the 
emergency gear extension cables.
    Although the incidents occurred on the ground, the airworthiness 
concern is the potential for this rudder restriction to occur in flight 
at high angles of rudder deflection.
    The FAA believes that a majority of the airplanes have already 
incorporated Service Bulletin 1188 and Service Bulletin 1213. However, 
the only way to mandate its incorporation is through AD action. In 
addition, the FAA believes that a large percentage of the airplanes 
that were manufactured after SB 1213 was issued could have the 
emergency gear extension cable routed incorrectly because the P-clamp 
that secures the cable could be installed on the inboard bolt just as 
easily as the outboard bolt (the type design configuration).
    Piper is establishing a very robust assembly/inspection procedure 
going forward to ensure that the quality escape issue does not reoccur. 
The FAA has determined that this condition can be addressed by 
requiring:
     The modification in Service Bulletin 1188 for all Models 
PA-44-180 and PA-44-180T airplanes manufactured prior to April 14, 2008 
(the date of SB 1188); and
     The inspection of the emergency gear inspection cable for 
correct routing of all Model PA-44-180 airplanes manufactured after 
April 14, 2008 (the date of SB 1188) following SB 1213A, dated October 
23, 2015.
    This condition, if not corrected, could result in restriction of 
the rudder movement at high angles of rudder deflection with consequent 
loss of control. We are issuing this AD to correct the unsafe condition 
on these products.

Related Service Information Under 1 CFR Part 51

    We reviewed Piper Aircraft, Inc. Service Bulletin No. 1213A, dated 
October 23, 2015. The service information describes procedures for 
inspection of the routing and security of the emergency gear extension 
cable and, if necessary, instructions to reroute the emergency gear 
extension cable. Piper considers compliance with this service bulletin 
mandatory.
    We reviewed Piper Aircraft, Inc. Service Bulletin No. 1188, dated 
April 14, 2008. The service information describes procedures to reroute 
and restrain the emergency gear extension cable. Piper considers 
compliance with this service bulletin mandatory.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information described previously.

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 if 
the emergency gear extension cable is left routed incorrectly, it could 
allow the copilot's left rudder pedal to become entangled with the 
cable, resulting in a restriction of rudder movement at high angles of 
rudder deflection with consequent 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 was not preceded by notice and an opportunity for public 
comment. 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-2015-8311 and 
Directorate Identifier 2015-CE-039-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 415 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

Install Piper emergency gear       2 work-hours x $85   $21................            $191  (Estimated 380

                                                                                              $72,580.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the either the results of the 
inspection or other requirements. We have no way of determining the 
number of aircraft that might need this replacement:

                                               On-Condition Costs

Reroute the emergency gear extension cable...  2 work-hours x $85 per hour =               $21             $191
                                                $170.
----------------------------------------------------------------------------------------------------------------

    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

[[Page 147]]

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.
