ACTION: Final rule.
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from mandatory continuing
airworthiness information (MCAI)
issued by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
Occurrence of cracks in the exhaust
muffler in the area of the exhaust bottom and
exhaust flange were reported, which could
lead to toxic contamination inside the cabin.
We are issuing this AD to require
actions to correct the unsafe condition
on these products, which could result in
carbon monoxide contamination in the
cockpit, which can adversely affect the

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on September 12, 2008 (73 FR
52932). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states that:
Occurrence of cracks in the exhaust
muffler in the area of the exhaust bottom and
exhaust flange were reported, which could
lead to toxic contamination inside the cabin.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comments received.
Suggestion To Pressurize the Muffler
With Air To Detect Leaks
One commenter, a private citizen,
suggests that we change the proposed
AD to inspect for cracks by pressurizing
the muffler with air and using a soap
solution to detect leaks. The commenter
states that this method would detect
finer cracks than just a visual inspection
would find.
We partially agree. The suggested
inspection is likely more sensitive, but
the visual inspections specified in the
E:\FR\FM\22DER1.SGM
22DER1
78174
Federal Register / Vol. 73, No. 246 / Monday, December 22, 2008 / Rules and Regulations
proposed AD are sensitive enough to
detect an exhaust leak that could create
an unsafe condition. However, operators
can request approval to use another
inspection method instead of using the
method specified in the AD, by
requesting approval of an alternative
method of compliance (AMOC). We did
not change the AD.
Request To Allow Repair of a Cracked
Muffler
The same commenter requests that we
change the proposed AD to allow the
repair of a cracked muffler instead of
replacing the muffler. The commenter
infers that this would be more cost
effective.
We disagree. The cracks occurring in
the mufflers are in weld areas that were
part of the original manufacturing
process. The muffler manufacturing
process was changed to correct the
cracking problem. A repair in the area
of the original weld might not correct
the unsafe condition and could make
the muffler more susceptible to future
cracking, thereby requiring continued
inspections. However, operators can
request approval of an AMOC for a
muffler repair method, but operators
would have to address the repair
concerns mentioned previously. We did
not change the AD.
Suggestion To Install a Carbon
Monoxide (CO) Detector in the Cockpit
The same commenter suggests that
operators install a CO detector in the
cockpit to identify presence of harmful
levels of CO. The commenter infers that
this would provide an additional level
of protection.
We disagree. The inspections
specified in the proposed AD are
adequate to detect an exhaust leak that
could create an unsafe condition. Also,
maintenance checks of the CO detector
would be required to ensure its correct
operation, if it was being relied on as a
method to prevent the unsafe condition.
We did not change the AD.
Conclusion
We reviewed the available data,
including the comments received, and
determined that air safety and the
public interest require adopting the AD
as proposed.

Costs of Compliance
Based on the service information, we
estimate that this AD will affect about
VerDate Aug<31>2005

Jkt 217001
75 products of U.S. registry. We also
estimate that it will take about 2 workhours per product to comply with this
AD. The average labor rate is $80 per
work-hour. Required parts will cost
about $1,674 per product. Based on
these figures, we estimate the cost of the
AD on U.S. operators to be $137,550.
Our cost estimate is exclusive of
possible warranty coverage.
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.

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
■
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
■
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:
■
We 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 this AD:
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); and
3. 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on September 12, 2008
(73 FR 52932). That NPRM proposed to correct an unsafe condition for
the specified products. The MCAI states that:
Occurrence of cracks in the exhaust muffler in the area of the
exhaust bottom and exhaust flange were reported, which could lead to
toxic contamination inside the cabin.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comments received.

One commenter, a private citizen, suggests that we change the
proposed AD to inspect for cracks by pressurizing the muffler with air
and using a soap solution to detect leaks. The commenter states that
this method would detect finer cracks than just a visual inspection

We partially agree. The suggested inspection is likely more

create an unsafe condition. However, operators can request approval to
use another inspection method instead of using the method specified in
the AD, by requesting approval of an alternative method of compliance

Request To Allow Repair of a Cracked Muffler
The same commenter requests that we change the proposed AD to allow
the repair of a cracked muffler instead of replacing the muffler. The
commenter infers that this would be more cost effective.
We disagree. The cracks occurring in the mufflers are in weld areas
that were part of the original manufacturing process. The muffler
manufacturing process was changed to correct the cracking problem. A

condition and could make the muffler more susceptible to future
cracking, thereby requiring continued inspections. However, operators
can request approval of an AMOC for a muffler repair method, but
operators would have to address the repair concerns mentioned

required to ensure its correct operation, if it was being relied on as
a method to prevent the unsafe condition. We did not change the AD.
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
the AD as proposed.
Costs of Compliance
Based on the service information, we estimate that this AD will
affect about 75 products of U.S. registry. We also estimate that it
will take about 2 work-hours per product to comply with this AD. The
average labor rate is $80 per work-hour. Required parts will cost about
$1,674 per product. Based on these figures, we estimate the cost of the
AD on U.S. operators to be $137,550. Our cost estimate is exclusive of
possible warranty coverage.
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 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 this AD:
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); and
3. 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.

Reason
(d) Occurrence of cracks in the exhaust muffler in the area of
the exhaust bottom and exhaust flange were reported, which could
lead to toxic contamination inside the cabin.
We are issuing this AD to prevent carbon monoxide contamination
in the cockpit, which can adversely affect the pilot, and possibly
result in loss of control of the aircraft.
