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 theeffective 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.


### 54399 Federal Register / Vol. 76, No. 170 / Thursday, September 1, 2011 / Proposed Rules

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
