Discussion Volare Carburetors, LLC recently informed us of an airplane experiencing power loss. Volare reported that the airplane engine’s carburetor, formerly known as a Precision Airmotive ‘‘machined-from-billet’’ HA–6 carburetor, had a loose mixture control sleeve that rotated in the carburetor body. That rotation restricted fuel flow and caused power loss. Volare also reported that the sleeve rotation was a manufacturing defect. In 2008, a similar power loss event occurred. At that time, the manufacturer recovered five carburetors, which represented all known discrepant carburetors. With this recent failure, however, the population of five affected carburetors is too small, and must be expanded. This condition, if not corrected, could result in in-flight shutdown or power loss, possibly resulting in reduced control of the airplane. Relevant Service Information We reviewed Marvel-Schebler Aircraft Carburetors LLC Emergency Service Bulletin (SB) No. SB–18, dated October 14, 2010. The SB identifies the affected population of HA–6 carburetors. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between the Proposed AD and the Service Information.’’ Differences Between the Proposed AD and the Service Information This proposed AD has a compliance time of within 50 flight hours after the effective date of the AD. The MarvelSchebler Aircraft Carburetors LLC Emergency SB No. SB–18, dated October 14, 2010, has a compliance time of before further flight. This proposed AD would not require returning the carburetor to the manufacturer. The SB does. Costs of Compliance We estimate that this proposed AD affects 10,700 engines installed on aircraft of U.S. registry. We also estimate that it would take about 0.5 work-hour per aircraft to perform the proposed inspection, and that about 409 carburetors would 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 would cost about $600 per carburetor. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $769,680. 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 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.

Discussion

    Volare Carburetors, LLC recently informed us of an airplane 
experiencing power loss. Volare reported that the airplane engine's 
carburetor, formerly known as a Precision Airmotive ``machined-from-
billet'' HA-6 carburetor, had a loose mixture control sleeve that 
rotated in the carburetor body. That rotation restricted fuel flow and 
caused power loss. Volare also reported that the sleeve rotation was a 
manufacturing defect.
    In 2008, a similar power loss event occurred. At that time, the 
manufacturer recovered five carburetors, which represented all known 
discrepant carburetors. With this recent failure, however, the 
population of five affected carburetors is too small, and must be 
expanded.
    This condition, if not corrected, could result in in-flight 
shutdown or power loss, possibly resulting in reduced control of the 
airplane.

Relevant Service Information

    We reviewed Marvel-Schebler Aircraft Carburetors LLC Emergency 
Service Bulletin (SB) No. SB-18, dated October 14, 2010. The SB 
identifies the affected population of HA-6 carburetors.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Differences Between the Proposed AD and the Service 
Information.''

Differences Between the Proposed AD and the Service Information

    This proposed AD has a compliance time of within 50 flight hours 
after the effective date of the AD. The Marvel-Schebler Aircraft 
Carburetors LLC Emergency SB No. SB-18, dated October 14, 2010, has a 
compliance time of before further flight.
    This proposed AD would not require returning the carburetor to the 
manufacturer. The SB does.

Costs of Compliance

    We estimate that this proposed AD affects 10,700 engines installed 
on aircraft of U.S. registry. We also estimate that it would take about 
0.5 work-hour per aircraft to perform the proposed inspection, and that 
about 409 carburetors would 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 would cost about $600 per 
carburetor. Based on these figures, we estimate the cost of the 
proposed AD on U.S. operators to be $769,680. 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 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.

[[Page 54399]]

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.

Unsafe Condition

    (d) 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.

Compliance

    (e) Comply with this AD within 50 flight hours after the 
effective date of this AD, unless already done.

Inspection

    (f) 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, 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:
    (i) An HA-6 carburetor not listed in Table 2 of this AD; or
    (ii) An HA-6 carburetor that is listed in Table 2 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 that has already 
been repaired using that Emergency SB.

Alternative Methods of Compliance (AMOCs)

    (i) The Manager, Engine Certification Office, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19.
