We are revising an earlier proposed airworthiness directive (AD) for certain Piper Aircraft, Inc. Model PA-31-350 airplanes. The NPRM proposed to require inspecting the fuel hose assembly and the turbocharger support assembly for proper clearance between them, inspecting each assembly for any sign of damage, and making any necessary repairs or replacements. The NPRM was prompted by a report of an engine fire caused by a leak in the fuel pump inlet hose. This action revises the NPRM by requiring the use of revised procedures in a new service bulletin. We are proposing this supplemental NPRM (SNPRM) to correct the unsafe condition on these products. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

Airworthiness Directives; Piper Aircraft, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) for certain Piper Aircraft, Inc. Model PA-31-350 airplanes. The 
NPRM proposed to require inspecting the fuel hose assembly and the 
turbocharger support assembly for proper clearance between them, 
inspecting each assembly for any sign of damage, and making any 
necessary repairs or replacements. The NPRM was prompted by a report of 
an engine fire caused by a leak in the fuel pump inlet hose. This 
action revises the NPRM by requiring the use of revised procedures in a 
new service bulletin. We are proposing this supplemental NPRM (SNPRM) 
to correct the unsafe condition on these products. Since these actions 
impose an additional burden over that proposed in the NPRM, we are 
reopening the comment period to allow the public the chance to comment 
on these proposed changes.

Discussion

    We issued an NPRM to amend 14 CFR part 39 by adding an AD that 
would apply to certain Piper Aircraft, Inc. Model PA-31-350 airplanes. 
The NPRM published in the Federal Register on June 3, 2014 (79 FR 
31888). The NPRM proposed to require inspecting the fuel hose assembly 
and the turbocharger support assembly for proper clearance between 
them, inspecting each assembly for any sign of damage, and making any 
necessary repairs or replacements.

Actions Since Previous NPRM Was Issued

    Since we issued the NPRM (79 FR 31888, June 3, 2014), Piper 
Aircraft, Inc. has revised the related service information to clarify 
which engines are part of the airplane applicability and to revise the 
accomplishment instructions for inspecting for proper clearance between 
the fuel hose assembly and the turbocharger support assembly, 
inspecting the fuel hose assembly and the turbocharger support assembly 
for any signs of damage, and taking all necessary corrective actions.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM (79 FR 
31888, June 3, 2014) and the FAA's response to the comment.

Request To Change the Applicability of the AD

    Joe Miller of Werbelow's Air Ventures, Inc., requested that the 
Applicability section of the AD be changed so that it applies only to 
Piper Aircraft, Inc. Model PA-31-350 airplanes with TIO-540-J2B engine 
configurations.
    The commenter stated that Model PA-31-350 airplanes configured with 
TIO-540-J2B engines have fuel pumps orientated such that their inlet 
fuel hose assemblies can adversely contact a nearby turbocharger 
support assembly. The commenter also stated that the other type 
certificated engine configurations of applicable Model PA-31-350 
airplanes have engine fuel pumps orientated such that their inlet fuel 
hose assemblies cannot adversely contact the nearby turbocharger 
support assembly.
    The commenter requested that the AD exclude Model PA-31-350 
airplanes that have the fuel pump installed on a Lycoming (L)TIO-540-
J2BD engine.
    We partially agree with the commenter. We agree that there is more 
than one orientation for the engine fuel pump in the applicable Model 
PA-31-350 airplanes with (L)TIO-540 series engines because this is 
shown in the Lycoming parts catalog for the TIO, LTIO-540-J2B, and -
J2BD engines, which were type certificated on the Model PA-31-350 
airplane.
    We disagree with the commenter's request to change the actions of 
the AD so that they apply only to the inlet hose assembly for the 
engine fuel pump of the TIO-540-J2B engine configuration of applicable 
Model PA-31-350 airplanes. We reviewed the Lycoming parts catalog for 
the TIO, LTIO-540-J2B, and -J2BD engines and applicable Model PA-31-350 
airplanes with (L)TIO-540-J2BD engines and found that the TIO and LTIO-
540-J2B and -J2BD engines each have a fuel pump with one fuel hose 
assembly (either and inlet or exit) that can be incorrectly installed 
so that it is in contact with the nearby turbocharger support assembly.

Related Service Information Under 1 CFR Part 51

    We reviewed Piper Aircraft, Inc. Service Bulletin No. 1257A, dated 
August 4, 2015. The service information describes procedures for the 
following. 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 of this 
SNPRM.

--Inspecting for a minimum 3/16-inch clearance between the fuel hose 
assembly and the turbocharger support assembly and making any necessary 
adjustments.
--Inspecting the fuel hose assembly for any signs of damage and, if 
necessary, replacing with a serviceable part.
--Inspecting the turbocharger support assembly for any signs of damage 
and, if necessary, repairing or replacing with a serviceable part.
--Performing an engine run-up to check for any leaks.

FAA's Determination

    We are proposing this SNPRM 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. 
Certain changes described above expand the scope of the NPRM (79 FR 
31888, June 3, 2014). As a result, we have determined that it is 
necessary to reopen the comment period to provide additional 
opportunity for the public to comment on this SNPRM.

Proposed Requirements of This SNPRM

    This SNPRM would require accomplishing the actions specified in the 
service information described previously, except as discussed under 
``Differences Between this Proposed AD and the Service Information.''

Differences Between This SNPRM and the Service Information

    There are differences between the compliance times for the 
corrective actions in this proposed AD and those in the related service 
information.
    We based the compliance times in this proposed AD on risk analysis 
and cost impact to operators. There has only been one event of the 
reported incident in the operational history of Piper Model PA-31-350 
airplanes. Cost was also a strong consideration due to the age of the 
fleet and the number of airplanes still in service.
    The one-time inspection required in this proposed AD is very 
inexpensive and requires minimal time to accomplish. It is expected 
that almost all airplanes in service can be cleared with a single 
inspection, and no additional actions or costs would be incurred by the 
vast majority of the fleet.
    We determined that a single inspection with any necessary 
corrective actions is an adequate terminating action for the unsafe 
condition. The risk related to future maintenance on the fuel line 
would be mitigated by the related service information and awareness 
from this proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 773 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.
