AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; rescission.

SUMMARY: We are rescinding an airworthiness directive (AD) for Lycoming
Engines model TIO-540-A series reciprocating engines. The existing AD,
AD 71-13-01, was prompted by a report of a failed fuel injector tube
assembly. Since we issued AD 71-13-01, we became aware that Lycoming
Engines no longer supports Service Bulletin (SB) No. 335A, which was
incorporated by reference in AD 71-13-01. The intent of the
requirements of that SB is now in Lycoming Engines Mandatory SB No.
342F, which we have incorporated by reference into AD 2008-14-07. The
FAA determined, therefore, that this requirement is duplicated by
another AD.

DATES: This AD is effective March 8, 2012.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to rescind an AD that would apply to the specified products.
That NPRM published in the Federal Register on July 19, 2011 (76 FR
42609). That NPRM proposed to rescind AD 71-13-01 (Amendment number is
39-1231; 36 FR 11512-03, June 15, 1971) for Lycoming Engines model TIO-
540-A series reciprocating engines. That AD requires a one-time visual
inspection of external fuel injector lines on Lycoming Engines model
TIO-540-A series reciprocating engines for fuel stains, cracks, dents,
and bend radii under \5/8\ inch and, if necessary, removal from service
and replacement with serviceable parts. That AD also requires
installing, if necessary, fuel injector line support clamps in
accordance with Lycoming Engines SB No. 335 or later version of that
SB.
Since we issued AD 71-13-01 (Amendment number is 39-1231; 36 FR
11512-03, June 15, 1971), Lycoming Engines has informed us that it no
longer supports SB No. 335A. They also pointed out that Lycoming
Engines Mandatory SB No. 342F, dated June 4, 2010, or the Instructions
for Continued Airworthiness section of the Engine Overhaul Manual is
the service information that owners, operators, and certificated repair
facilities must use for initial and repetitive visual inspections of
external fuel lines on all affected Lycoming Engines reciprocating
engines.
We incorporated by reference Lycoming Engines Mandatory SB No.
342E, dated May 18, 2004, into AD 2008-14-07 (73 FR 39574, July 10,
2008). We will supersede AD 2008-14-07 to incorporate by reference
Lycoming Engines Mandatory SB No. 342F, dated June 4, 2010.

Comments

We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (76 FR 42609, July 19,
2011).

Conclusion

We reviewed the relevant data and determined that air safety and
the public interest require rescinding the AD as proposed.

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.
