PREAMBLE 

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

SUMMARY: We are superseding an existing airworthiness directive (AD)
for certain fuel injected reciprocating engines manufactured by
Lycoming Engines. That AD currently requires inspection, replacement if
necessary, and proper clamping of externally
mounted fuel injector fuel lines. That AD also states that it is not
applicable to engines that have a Maintenance and Overhaul Manual with
an Airworthiness Limitations Section that requires inspection and
replacement, if necessary, of externally mounted fuel injector lines.
This new AD requires the same actions. This AD was prompted by Lycoming
Engines revising their Mandatory Service Bulletin (MSB) to add engine
models requiring inspections. We are issuing this AD to prevent failure
of the fuel injector fuel lines that would allow fuel to spray into the
engine compartment, resulting in an engine fire.

DATES: This AD is effective January 25, 2012.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of January 25,
2012.

ADDRESSES: For service information identified in this AD, contact
Lycoming Engines, 652 Oliver Street, Williamsport, PA 17701, or go to

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2008-14-07, Amendment 39-15602 (73 FR 39574,
July 10, 2008). That AD applies to the specified products. The NPRM
published in the Federal Register on February 15, 2011 (76 FR 8661).
That NPRM proposed to inspect, replace if necessary, and properly clamp
externally mounted fuel injector fuel lines. That AD also states that
it is not applicable to engines that have a Maintenance and Overhaul
Manual with an Airworthiness Limitations Section that requires
inspection and replacement, if necessary, of externally mounted fuel
injector lines.

Comments

We gave the public the opportunity to participate in developing
this AD. The following presents the comment received on the proposal
and the FAA's response to the comment.

Question

One commenter asked why the AD requirements are only for Lycoming
engines, and not also for Teledyne Continental Motors (TCM) engines.
The commenter inferred that we write ADs, just to make owners maintain
their aircraft.
In response, any AD made applicable to TCM engines with externally
mounted fuel injector lines, would have to be written by the Atlanta
Aircraft Certification Office (ACO), because that office has oversight
of TCM. The Atlanta ACO has informed us that at this time, there is
insufficient data to justify an AD for TCM engines with externally
mounted fuel injector lines, however, they realize there may be
justification for issuing a Special Airworthiness Information Bulletin
(SAIB), for TCM engines on this subject. They are looking into possibly
issuing an SAIB.

Conclusion

We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting the
AD as proposed.

Costs of Compliance

We estimate that this AD affects 21,180 four-cylinder engines,
21,449 six-cylinder engines, and 256 eight-cylinder engines installed
on aircraft of U.S. registry. We also estimate that it will take about
0.2 work-hour to inspect all lines on a four-cylinder engine, 0.5 work-
hour to inspect all lines on a six-cylinder engine, and 0.7 work-hour
to inspect all lines on an eight-cylinder engine. We also estimate that
the average labor rate is $85 per work-hour. We do not anticipate any
additional costs on U.S. operators, as the inspection would be done in
conjunction with other work performed concurrently. We anticipate no
parts to be required. Based on these figures, the total cost of the AD
to U.S. operators for one inspection of the fleet is $1,286,875.

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.

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:

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.

Sec. 39.13 [Amended]

2. The FAA amends Sec. 39.13 by removing airworthiness directive (AD)
2008-14-07, Amendment 39-15602 (73 FR 39574, July 10, 2008), and adding
the following new AD:
