Federal Register Abstract
We are adopting a new airworthiness directive (AD) for certain Lycoming TIO-540-AJ1A reciprocating engines. This AD was prompted by several reports of cracked engine exhaust pipes. This AD requires inspection of the engine exhaust pipes for cracks and replacement of the turbocharger mounting bracket. We are issuing this AD to prevent failure of the exhaust system due to cracking, which could lead to uncontrolled engine fire, harmful exhaust gases entering the cabin resulting in crew incapacitation, and damage to the airplane.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain Lycoming TIO-540-
AJ1A reciprocating engines. The NPRM published in the Federal Register
on February 2, 2015 (80 FR 5489). The NPRM was prompted by several
reports of cracked engine exhaust pipes. The NPRM proposed to require
inspection of the engine exhaust pipes for cracks and replacement of
the turbocharger mounting bracket. We are issuing this AD to prevent
failure of the exhaust system due to cracking, which could lead to
uncontrolled engine fire, harmful exhaust gases entering the cabin
resulting in crew incapacitation, and damage to the airplane.
Related Service Information Under CFR Part 51
We reviewed Lycoming Engines Mandatory Service Bulletin No. 614A,
dated October 10, 2014. This service bulletin describes procedures for
exhaust system inspection and turbocharger mounting bracket
replacement. It also provides for the return of the turbocharger
mounting bracket to Lycoming. 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 AD.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (80 FR 5489, February 2,
2015) 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.
Costs of Compliance
We estimate that this AD affects about 111 engines installed on
airplanes of U.S. registry. We also estimate that it will take about 8
hours per engine to comply with this AD. The average labor rate is $85
per hour. Parts replacement will cost about $6,782 per engine. Based on
these figures, we estimate the cost of this AD on U.S. operators to be
$828,282. 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
[[Page 30346]]
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 to the extent
that it justifies making a regulatory distinction, 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:

(d) Unsafe Condition
This AD was prompted by several reports of cracked engine
exhaust pipes. We are issuing this AD to prevent failure of the
exhaust system due to cracking, which could lead to uncontrolled
engine fire, harmful exhaust gases entering the cabin resulting in
crew incapacitation, and damage to the airplane.
(e) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(1) For affected engines with an S/N listed in Figure 1 to
paragraph (c) of this AD with 400 hours or less time since new (TSN)
or time since last overhaul (TSLO), and for any TIO-540-AJ1A
reciprocating engine with a replacement turbocharger mounting
bracket installed that was purchased between April 5, 2012 and May
29, 2014, that has accumulated 400 hours or less time-in-service
(TIS), within 25 hours after the effective date of this AD, replace
the turbocharger mounting bracket with a part eligible for
installation, and inspect the exhaust pipes for cracks. Use Lycoming
Engines Mandatory Service Bulletin (MSB) No. 614A, dated October 10,
2014, Exhaust System Disassembly and Removal, paragraphs 1 through
22 to replace the bracket, and Exhaust System Inspection, paragraphs
1 through 5 to do the inspection.
[[Page 30347]]
(2) For affected engines with an S/N listed in Figure 1 to
paragraph (c) of this AD with more than 400 hours TSN or TSLO, and
for any TIO-540-AJ1A reciprocating engine with a replacement
turbocharger mounting bracket installed that was purchased between
April 5, 2012 and May 29, 2014, that has accumulated more than 400
hours TIS, replace the turbocharger mounting bracket with a part
eligible for installation, and inspect the exhaust pipes for cracks
at the next engine overhaul, separation of the crankcase halves, or
twelve years from the effective date of this AD, whichever comes
first. Use Lycoming Engines MSB No. 614A, dated October 10, 2014,
Exhaust System Disassembly and Removal, paragraphs 1 through 22 to
replace the bracket, and Exhaust System Inspection, paragraphs 1
through 5 to do the inspection.
(f) Installation Prohibition
After the effective date of this AD, do not return to service
any TIO-540-AJ1A engine with a turbocharger mounting bracket that
was removed from an engine identified in Figure 1 to paragraph (c)
of this AD or that was purchased between April 5, 2012 and May 29,
2014.
(g) Credit for Previous Action
(1) If, before the effective date of this AD, you replaced the
turbocharger mounting bracket with one eligible for installation you
may take credit for your prior corrective action. No further
turbocharger mounting bracket replacement is required.
(2) If, before the effective date of this AD, you performed the
crack inspection using either of the following:
(i) Lycoming Engines MSB No. 614A, dated October 10, 2014,
Exhaust System Inspection, paragraphs 1 through 5, or
(ii) Cessna Service Letter No. SEL-78-01, dated May 30, 2014,
you may take credit for your prior corrective action. No further
inspection is required. However, you must still replace the
turbocharger mounting bracket.
(h) Alternative Methods of Compliance (AMOCs)
The Manager, New York Aircraft Certification Office, FAA, may
approve AMOCs to this AD. Use the procedures found in 14 CFR 39.19
to make your request.
