14 CFR Part 39

[Docket No. FAA-2007-0218; Directorate Identifier 92-ANE-56-AD; 
Amendment 39-16894; AD 2011-26-04]
RIN 2120-AA64


Airworthiness Directives; Lycoming Engines, Fuel Injected 
Reciprocating Engines

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

[[Page 79052]]

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.

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.
