Airworthiness Directive (AD) 69–13–03
for all Piper Aircraft, Inc. Models PA–
23, PA–23–160, PA–23–235, PA–23–
250, PA–E23–250, and PA–30 airplanes.
AD 69–13–03 required inspection of the
heater exhaust extension, replacement
of the extension as necessary, and
overhaul of the combustion heater
assembly. This AD retains the
inspection of the heater exhaust
extension with replacement of the
extension as necessary and removes the
overhaul requirement of the combustion
heater assembly. This AD was prompted
by a recently issued AD that applies to
the Meggitt (Troy), Inc. combustion
heaters, and the combustion heater AD
incorporates corrective actions for the
heater that contradict the overhaul
requirement of AD 69–13–03. We are
issuing this AD to continue to address
the unsafe condition on these products
and avoid potential contradiction of
actions.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 69–13–03,
Amendment 39–785 (34 FR 9748, June
24, 1969) as amended by AD 69–13–03,
Amendment 39–1749 (38 FR 33765,
December 7, 1973), (‘‘AD 69–13–03’’).
AD 69–13–03 applied to certain Piper
Aircraft, Inc. Models PA–23, PA–23–
160, PA–23–235, PA–23–250, PA–E23–
250, and PA–30 airplanes. AD 69–13–03
required inspection of the heater
exhaust extension to determine if it is
mild steel or stainless steel, repetitive
inspections of the mild steel extensions
for deterioration, replacement of the
extension as necessary, and overhaul of
the combustion heater assembly. AD
69–13–03 resulted from the potential of
carbon monoxide entering the airplane
cabin.
The NPRM was prompted by another
AD action that applies to the Meggitt
(Troy), Inc. combustion heaters installed
on the airplanes AD 69–13–03 applied
to. AD 2017–06–03; Amendment 39–
18827 (82 FR 15988, March 31, 2017),
which applies to the Meggitt
combustion heaters incorporates
corrective actions for the heater that
contradict the overhaul requirement of
AD 69–13–03. The NPRM proposed to
retain certain requirements of AD 69–
13–03 and remove the requirement for
overhaul of the heater assembly. We are
issuing this AD continue to address the
unsafe condition on these products and
avoid potential contradiction of actions.
Comments
We gave the public the opportunity to
participate in developing this AD. One
comment was received from Ahmed Ali
who agrees with the AD action. The
following presents the other comment
received on the NPRM and the FAA’s
response to the comment.
Request To Withdraw NPRM
Jeff Aryan stated the AD is not
necessary. The commenter has owned a
Model PA–30 airplane for 25 years and
does not believe heater fumes can enter
the cabin. He has used the heater for

Federal Register / Vol. 82, No. 140 / Monday, July 24, 2017 / Rules and Regulations
prolonged periods of time, with and
without the engine running, and has not
experienced any problems. He stated the
exhaust system was well designed and
does not need to be changed. He
believes owners are not maintaining
their airplane to the regulations. We
infer the commenter would like for us
to withdraw the NPRM.
We disagree with this comment. The
potential exists for carbon monoxide to
enter the cabin when the mild steel
exhaust extension deteriorates. The
required actions of this AD will
continue to address the unsafe
condition.
We have not changed this AD based
on 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
as proposed except for minor editorial
changes. We have determined that these
minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 1,950
airplanes of U.S. registry.
We estimate the following costs to
comply with this AD. The new
requirements of this AD add no
additional economic burden:

69-13-03 applied to. AD 2017-06-03; Amendment 39-18827 (82 FR 15988,
March 31, 2017), which applies to the Meggitt combustion heaters
incorporates corrective actions for the heater that contradict the
overhaul requirement of AD 69-13-03. The NPRM proposed to retain
certain requirements of AD 69-13-03 and remove the requirement for
overhaul of the heater assembly. We are issuing this AD continue to
address the unsafe condition on these products and avoid potential
contradiction of actions.
Comments
We gave the public the opportunity to participate in developing
this AD. One comment was received from Ahmed Ali who agrees with the AD
action. The following presents the other comment received on the NPRM
and the FAA's response to the comment.
Request To Withdraw NPRM
Jeff Aryan stated the AD is not necessary. The commenter has owned
a Model PA-30 airplane for 25 years and does not believe heater fumes
can enter the cabin. He has used the heater for
[[Page 34258]]
prolonged periods of time, with and without the engine running, and has
not experienced any problems. He stated the exhaust system was well
designed and does not need to be changed. He believes owners are not
maintaining their airplane to the regulations. We infer the commenter
would like for us to withdraw the NPRM.
We disagree with this comment. The potential exists for carbon
monoxide to enter the cabin when the mild steel exhaust extension
deteriorates. The required actions of this AD will continue to address
the unsafe condition.
We have not changed this AD based on 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 as proposed except for minor editorial changes. We have
determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 1,950 airplanes of U.S. registry.
We estimate the following costs to comply with this AD. The new
requirements of this AD add no additional economic burden:

We estimate the following costs to do any necessary corrective
actions that would be required based on the results of the inspection.
We have no way of determining the number of airplanes that might need
these corrective actions:

* There are currently no replacement parts available for the heater exhaust extension. The $1,000 parts cost is
the FAA's best estimate if parts were to become available.
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 have determined that 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.
