SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA received a report from Piper that incorrect rivets were 
installed in the bulkhead assembly at fuselage station (FS) 79.00 
during the manufacture of certain serial-numbered Model PA-46-600TP 
(M600) airplanes. The rivets were not in accordance with the type 
design drawing, nor did they meet the strength requirements of the 
aircraft design. This condition, if not corrected, could result in 
failure of the rivets, which could lead to structural failure of the 
bulkhead assembly and loss of control of the airplane. The FAA is 
issuing this AD to correct the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Piper Service Bulletin No. 1332A, dated January 
29, 2019. The service bulletin contains procedures for inserting the 
temporary ground operating limitation into the pilot's operating 
handbook (POH) and installing a placard with the temporary ground 
operating limitation, either a fabricated placard or placard part 
number 46G110013-702, in the airplane cockpit. The service bulletin 
also contains procedures for inspecting the FS 79.00 bulkhead assembly 
for cracks, wrinkling, or missing rivets and for replacing the 
understrength rivets with new rivets. 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

    The FAA is issuing this AD because the FAA 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 inserting a ground operating limitation into the 
Limitations section of the AFM and installing a placard in the airplane 
cockpit that limits ground operations. This AD also includes an 
optional action to terminate the ground operating limitation by 
replacing the rivets to reinforce the bulkhead assembly. Although 
Piper's service information specifies inserting the operating 
limitation into the POH, Piper's POH for the Model PA-46-600TP 
constitutes its FAA-approved AFM.

Interim Action

    The FAA considers this AD interim action. The FAA may require 
replacement of the rivets to reinforce the bulkhead assembly. However, 
the planned compliance time for the replacement of the rivets would 
allow enough time to provide notice and opportunity for prior comment 
on the merit of the replacement.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because the required corrective actions must be accomplished before 
further flight. Providing prior notice and comment would delay 
implementing these safety actions needed to correct this known unsafe 
condition, which could result in structural failure of the FS 79.00 
bulkhead, resulting in loss of control of the airplane. Therefore, the 
FAA finds good cause that notice and opportunity for prior public 
comment are impracticable. In addition, for the reason stated above, 
the FAA finds 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, the FAA invites you to send any written data, views, 
or arguments about this final rule. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number FAA-2019-
0447 and Product Identifier 2018-CE-055-AD at the beginning of your 
comments. The FAA specifically invites comments on the overall 
regulatory, economic, environmental, and energy aspects of this final 
rule. The FAA will consider all comments received by the closing date 
and may amend this final rule because of those comments.
    The FAA will post all comments the FAA receives, without change, to 
http://www.regulations.gov, including any personal information you 
provide. The FAA will also post a report summarizing each substantive 
verbal contact the FAA receives about this final rule.

Costs of Compliance

    The FAA estimates that this AD affects 69 airplanes, of U.S. 
registry.
    The FAA estimates the following costs to comply with this AD:

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. The FAA does not control warranty coverage for affected 
individuals. As a result, the FAA has included all costs in their 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.
    The FAA is 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to small airplanes, gliders, 
balloons, airships, domestic business jet transport airplanes, and 
associated appliances to the Director of the Policy and Innovation 
Division.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because FAA has determined 
that it has good cause to adopt this rule without notice and comment, 
RFA analysis is not required.

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, and
    (2) Will not affect intrastate aviation in Alaska.

Instructions, Part II Rework, of Piper SB No. 1332A.
    (2) If the FS 79.00 bulkhead rivets have been replaced as 
specified in paragraph (h)(1) of this AD, you may remove the AFM 
revision and placard required by paragraph (g) of this AD.
