SUPPLEMENTARY INFORMATION:

Discussion

    On October 1, 2015, we issued AD 2015-20-13, Amendment 39-18292 (80 
FR 61725), (``AD 2015-20-13''), for certain Piper Aircraft, Inc. Models 
PA-28-161, PA-28-181, and PA-28R-201 airplanes. AD 2015-20-13 required 
inspecting the right wing rib at wing station 140.09 for cracks and 
taking necessary corrective action. AD 2015-20-13 resulted from a 
report from Piper Aircraft, Inc. of a production quality control 
problem on certain Models PA-28-161, PA-28-181, and PA-28R-201 
airplanes. A change in production tooling and processes caused cracks 
to form along the edge of rib stiffening beads during manufacture. 
These cracks cause reduced structural integrity of the wing, which 
resulted in the inability of the wing rib to carry ultimate load. We 
issued AD 2015-20-13 to detect and correct cracks in the wing rib, 
which if not corrected, could result in reduced structural integrity of 
the wing with consequent loss of control.

Actions Since AD 2015-20-13 Was Issued

    Since we issued AD 2015-20-13, we received reports that operators 
in the field found the same cracks in airplanes outside the original 
applicability. After further investigation, Piper Aircraft, Inc. issued 
a new service bulletin expanding the serial number applicability of the 
affected airplane models. 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. 1279A, dated 
March 3, 2016. The service bulletin describes procedures for inspecting 
the right wing rib at wing station 140.09 for cracks and for obtaining 
an FAA-

[[Page 21262]]

approved repair if cracks are found. 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 
cracks in the wing rib, if not detected and corrected immediately, 
could result in reduced structural integrity of the wing 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 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-2016-5432 and directorate identifier 2016-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 725 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
----------------------------------------------------------------------------------------------------------------
Inspect the right wing rib at    1 work-hour x $85  Not applicable..............             $85         $61,625
 wing station 140.09 for cracks.  per hour = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs that 
will be required based on the results of the inspection. This estimate 
is based on replacement of the rib. We have no way of determining the 
number of airplanes that might need these repairs:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                 Labor cost               Parts cost        product
----------------------------------------------------------------------------------------------------------------
Repair of the of the wing rib.................  35 work-hours x $85 per hour =              $125          $3,100
                                                 $2,975.
----------------------------------------------------------------------------------------------------------------

    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.
    The only cost difference between this AD and AD 2015-20-13 is the 
cost associated with adding 710 airplanes to the Applicability section.

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.
