AD 2015-24-05

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.

Final rule.

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/operatorwith 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 ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspection to determine if .5 work-hour x $85 per Not Applicable.... $42.50 $127,500
placard, if installed, and hour = $42.50.
Limitations Section of the POH/
AFM are compliant with Piper
Aircraft, Inc. Service Bulletin
No. 1266, dated December 16,
2014. ----------------------------------------------------------------------------------------------------------------

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:

On-Condition Costs ----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Order and install replacement placard...... 1 work-hour x $85 per hour = $85... $40 $125 Order updated POH/AFM and install updated .5 work-hour x $85 per hour = 300 342.50
pages. $42.50. ----------------------------------------------------------------------------------------------------------------

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.
