We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Model PA-31-350 airplanes. This AD was prompted by a report of an engine fire caused by a leak in the fuel pump inlet hose. This AD requires 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. We are issuing this AD to correct the unsafe condition on these products.

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. Model PA-31-350 airplanes. This AD was prompted by 
a report of an engine fire caused by a leak in the fuel pump inlet 
hose. This AD requires 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. We are issuing this AD to correct 
the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 by adding an AD that would apply to certain Piper 
Aircraft, Inc. Model PA-31-350 airplanes. The SNPRM published in the 
Federal Register on January 26, 2016 (81 FR 4214). We preceded the 
SNPRM with a notice of proposed rulemaking (NPRM) that 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. The NPRM was prompted by a report of an engine fire on a 
Piper Aircraft, Inc. (Piper) Model PA-31-350 airplane. Investigation 
revealed that the fire was caused by a leak in the fuel pump inlet hose 
that resulted from repeated contact with an adjacent turbocharger 
support assembly caused by inadequate clearance between the two 
assemblies. The SNPRM proposed to require the same actions as proposed 
in the NPRM using revised service information issued by the 
manufacturer to clarify which engines are part of the airplane 
applicability and to revise the instructions for accomplishing the 
proposed actions.
    This condition, if not corrected, could result in damage to the 
fuel inlet hose assembly, which could cause the fuel pump inlet hose to 
fail and leak fuel in the engine compartment. This condition could also 
cause damage to the turbocharger support assembly, which could require 
the turbocharger support assembly to be repaired or replaced.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the SNPRM (81 FR 4214, January 26, 
2016) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM (81 FR 4214, January 26, 2016) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM (81 FR 4214, January 26, 2016).

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

[[Page 26107]]

available because the interested parties have access to it through 
their normal course of business or by the means identified in the 
ADDRESSES section.

--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.

Differences Between This AD and the Service Information

    There are differences between the compliance times for the 
corrective actions in this AD and those in the related service 
information.
    We based the compliance times in this 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 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 AD.

Costs of Compliance

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

    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.

before further flight, perform an engine run-up on the ground to 
check for leaks. Do the engine run-up following the INSTRUCTIONS 
section of Piper Aircraft, Inc. Service Bulletin No. 1257A, dated 
August 4, 2015.
    (2) If any leaks found during the engine run-up required in 
paragraph (j)(1) of this AD emanate from any fuel line component 
adjusted, repaired, or replaced during any actions required in 
paragraphs (g)(1) through (i)(2) of this AD, before further flight, 
take all necessary corrective actions following the INSTRUCTIONS 
section of Piper Aircraft, Inc. Service Bulletin No. 1257A, dated
