14 CFR Part 39
[Docket No. FAA-2011-0533; Directorate Identifier 2011-NE-16-AD;
Amendment 39-16948; AD 2012-03-07]
RIN 2120-AA64
Airworthiness Directives; Lycoming Engines Reciprocating Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Lycoming Engines reciprocating engines. This AD was prompted by a
report of a ``machined-from-billet'' HA-6 carburetor having a loose
mixture control sleeve that rotated in the carburetor body causing
restriction of fuel and power loss. This AD requires removing certain
``machined-from-billet'' Volare LLC (formerly Precision Airmotive
Corporation, formerly Facet Aerospace Products Company, formerly
Marvel-Schebler (BorgWarner)) HA-6 carburetors, inspecting for a loose
mixture control sleeve or for a sleeve that may become loose, repairing
the carburetor, or replacing the carburetor with one eligible for
installation. We are issuing this AD to prevent engine in-flight
shutdown, power loss, and reduced control of the airplane.
DATES: This AD is effective March 27, 2012.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of March 27,
2012.

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 published in the Federal Register on September 1, 2011 (76 FR
54397). That NPRM proposed to require removing certain ``machined-from-
billet'' Volare LLC (formerly Precision Airmotive Corporation, formerly
Facet Aerospace Products Company, formerly Marvel-Schebler
(BorgWarner)) HA-6 carburetors, inspecting for a loose mixture control
sleeve or for a sleeve that may become loose, repairing the carburetor,
or replacing the carburetor with one eligible for installation.
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.
Request To Incorporate All Affected Engine Models
One commenter, a private citizen, requested that we incorporate all
affected engine models with HA-6 model carburetors installed in the AD.
The commenter provided a list, which he compiled from reviewing all
applicable published Type Certificate Data Sheets (TCDS).
We partially agree. We agree that some additional models are
affected because the list provided by the commenter is mostly
consistent with the applicable TCDS. We do not agree with the commenter
on some of the models he thinks are affected, because we could not
confirm they are affected, based on the TCDS. However, we determined
that we need to change the applicability from a table of specific
engine models, to all Lycoming Engines reciprocating engines with
carburetor part numbers listed in Table 1 of the AD. We changed the AD
applicability to all Lycoming Engines reciprocating engines with
carburetor part numbers listed in Table 1 of the AD.
Change to the Alternative Methods of Compliance (AMOC) Paragraph
Since we issued the proposed AD, we found that we referenced the
wrong office in the AMOC paragraph. We changed that sentence to state
that the Manager, Atlanta Aircraft Certification Office, FAA, may
approve AMOCs for this AD.
Change to Service Information
Marvel-Schebler Aircraft Carburetors LLC has revised their Marvel-
Schebler Emergency Service Bulletin (SB) No. SB-18, dated October 14,
2010, to Revision A, dated March 15, 2011. We reviewed Revision A, and
determined that it also is acceptable. We changed the incorporated by
reference paragraph k of the AD to include the original issue and
Revision A.
Conclusion
We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting the
AD with the changes described previously. We also determined that these
changes will not increase the economic burden on any operator or
increase the scope of the AD.
[[Page 9838]]
Costs of Compliance
We estimate that this AD affects 10,700 engines installed on
aircraft of U.S. registry. We also estimate that it will take about 0.5
work-hours per aircraft to perform the inspection, and that about 409
carburetors will need repair. Approximately 2 work-hours per carburetor
are required to repair the carburetor. The average labor rate is $85
per work-hour. Required parts will cost about $600 per carburetor.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $769,680. Our 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
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.

(d) Unsafe Condition
This AD was prompted by a report of a ``machined-from-billet''
HA-6 carburetor having a loose mixture control sleeve that rotated
in the carburetor body causing restriction of fuel and power loss.
We are issuing this AD to prevent engine in-flight shutdown, power
loss, and reduced control of the airplane.
(e) Compliance
Comply with this AD within 50 flight hours after the effective
date of this AD, unless already done.
(f) Inspection
Inspect the carburetor to determine the type of body the
carburetor has. Use Marvel-Schebler Emergency Service Bulletin (SB)
No. SB-18, dated October 14, 2010, or Revision A, dated March 15,
2011, Figure (3) to determine which type of body is used.
(g) If the carburetor has a die-cast body, no further action is
required.
(h) If the carburetor has an affected ``machined-from-billet''
body, remove the carburetor; and replace the carburetor with:
(1) An HA-6 carburetor not listed in Table 1 of this AD; or
(2) An HA-6 carburetor that is listed in Table 1 but is exempted
as described in paragraphs 1.A. and 1.B of Marvel-Schebler Emergency
SB No. SB-18, dated October 14, 2010 or Revision A, dated March 15,
2011; or that has already been repaired using that Emergency SB.
