Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2015-0627; Directorate Identifier 2015-CE-002-AD; 
Amendment 39-18337; AD 2015-24-05]
RIN 2120-AA64


Airworthiness Directives; Piper Aircraft, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Piper Aircraft, Inc. Models PA-23-250, PA-24-250, PA-24-260, PA-24-400, 
PA-30, PA-31, PA-31-300, PA-31P, PA-39, and PA-E23-250 airplanes. This 
AD was prompted by an accident caused by fuel starvation where the 
shape of the wing fuel tanks and fuel below a certain level in that 
tank may have allowed the fuel to move away from the tank outlet during 
certain maneuvers. This AD requires installing a fuel system management 
placard on the airplane instrument panel and adding text to the 
Limitations Section of the pilot's operating handbook (POH)/airplane 
flight manual (AFM). We are issuing this AD to correct the unsafe 
condition on these products.

DATES: This AD is effective January 12, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 12, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Piper Aircraft, 
Inc. Models PA-23-250, PA-24-250, PA-24-260, PA-24-400, PA-30, PA-31, 
PA-31-300, PA-31P, PA-39, and PA-E23-250 airplanes. The NPRM published 
in the Federal Register on March 23, 2015 (80 FR 15171). The NPRM was 
prompted by an accident caused by fuel starvation where the shape of 
the wing fuel tanks and fuel below a certain level in that tank may 
have allowed the fuel to move away from the tank outlet during certain 
maneuvers. The NPRM proposed to require installing a fuel system 
management placard on the airplane instrument panel and adding text to 
the Limitations Section of the pilot's operating handbook (POH)/
airplane flight manual (AFM). We are issuing this AD to correct the 
unsafe condition on these products.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (80 
FR 15171, March 23, 2015) and the FAA's response to each comment.

Request for Local Fabrication of the Required Warning Placard

    Edward Rognerud and an anonymous commenter requested that the AD be 
written to allow for the local fabrication of the required warning 
placard as long as it contains the exact warning text mandated by the 
service information and is printed in 8-point type. The anonymous 
commenter also requested that the AD allow for the installation of the 
warning placard onto the instrument panel at any location that does not 
obscure existing controls, instruments, or markings and is in clear 
view of the pilot.
    The commenters requested this change as a means of controlling the 
cost of compliance without compromising safety.
    We agree with the commenters that local fabrication of the warning 
placard may be necessary if the shape of the placard available from 
Piper Aircraft, Inc. does not fit on the instrument panel. The service 
information contains the exact text, font size, and installation 
restrictions necessary for the local fabrication of a compliant 
placard. Paragraph (g)(2) of the proposed AD included instructions to 
fabricate and install the placard. This implied that the placard can 
only be fabricated if the placard available from Piper Aircraft, Inc. 
does not fit on the instrument panel.
    We revised the AD as requested to allow for the fabrication of the 
placard following the instructions in the service information under any 
condition.

Request for Local Fabrication of the Supplemental Page for Updating of 
the Aircraft's POH/AFM

    Edward Rognerud and an anonymous commenter requested the updating 
of the airplane's POH/AFM by inserting a locally fabricated 
supplemental page into the Limitation Section as an alternative to 
inserting a supplemental page bought from Piper Aircraft, Inc. We infer 
the commenter's meaning to be that a locally fabricated supplemental

[[Page 76202]]

page will meet the requirements of the AD.
    The commenters requested this change as a means of controlling the 
cost of compliance without compromising safety.
    We agree with the commenters that compliance can be shown with 
paragraph (h)(3) of the AD by inserting into the Limitations Section of 
the POH/AFM a locally made supplemental page containing the applicable 
placard text or a supplemental page procured from Piper Aircraft, Inc.
    We revised the AD as requested.

Request Private Pilot Certificate as a Minimum Credential for AD 
Signoff in Logbook

    An anonymous commenter requested a private pilot certificate as a 
minimum credential for AD signoff in airplane's logbook. The anonymous 
commenter requested this change to control cost of compliance without 
compromising safety.
    We agree with the anonymous commenter. We determined that the 
installation of a purchased or locally fabricated supplemental page 
into the POH/AFM can be done by the owner/operator with at least a 
private pilot certificate. We have also determined that the local 
fabrication and installation of the placard following the instructions 
in the service bulletin can be done by the owner/operator with at least 
a private pilot certificate.
    We revised the AD as requested.

Request Withdrawal of the NPRM

    Jeffrey Aryan commented that the proposed AD is not appropriate. 
The commenter also wrote that the proposed AD would add a more 
cumbersome display to an already crowded flight deck. We infer that the 
commenter requested withdrawal of the NPRM.
    We disagree. The FAA evaluated all relevant information and 
determined that the addition of the placard to the instrument panel and 
the supplemental pages to the Limitations Section of the POH/AFM will 
address the unsafe condition identified in the AD.
    We made no change to the AD as a result of this comment.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     [Agr]re consistent with the intent that was proposed in 
the NPRM (80 FR 15171, March 23, 2015) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 15171, March 23, 2015).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed Piper Aircraft, Inc. Service Bulletin No. 1266, dated 
December 16, 2014. Piper Aircraft, Inc. Service Bulletin No. 1266, 
dated December 16, 2014, calls for/describes actions for, when 
necessary, installing the correct fuel warning placard on the 
instrument panel and adding correct text of that fuel warning placard 
in the Limitations Section of the POH/AFM. This 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 of this AD.

Costs of Compliance

    We estimate that this proposed AD affects 3,000 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs

    We estimate the following costs to do any necessary placard/POH/AFM 
order and installation that would be required based on the results of 
the inspection. We have no way of determining the number of airplanes 
that might need any necessary placard/POH/AFM order and installation:

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

[[Page 76203]]

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.
