Comments will be available in the AD docket shortly after receipt. Discussion We received three reports of failure of Ontic Engineering and Manufacturing, Inc. propeller governors. One of the reports was of a Diamond DA–40 airplane losing propeller pitch control during flight. The propeller governor controls propeller pitch by regulating oil pressure to the propeller pitch change mechanism. Changes in governor oil pressure are made by small changes in axial displacement of the governor’s pilot valve plunger assembly. A fly weight governor opposes a compressed spring that rides on a collar which forms a part of the pilot valve plunger assembly. Investigation revealed that the set screw securing the collar to the pilot valve plunger assembly shaft may not be installed properly on a batch of parts permitting the pilot valve plunger to float on the shaft. The pilot valve shaft plunger and captive thrust bearing are then free to move axially along the pilot valve shaft. When the pilot valve is unconstrained in the axial direction, the propeller governor cannot control oil pressure to the propeller pitch control mechanism. This results in a loss of propeller pitch control. Further, concurrent thrust bearing failure permits bearing debris to flow with the oil into the engine lubrication system. The engine in the incident airplane was internally damaged as a result of a E:\FR\FM\15MRP1.SGM 15MRP1 Federal Register / Vol. 75, No. 49 / Monday, March 15, 2010 / Proposed Rules propeller governor bearing ball becoming lodged between the valve lifter and engine case. This condition, if not corrected, could result in loss of propeller pitch control, damage to the propeller governor, and internal damage to the engine, which could prevent continued safe flight or safe landing. Relevant Service Information We have reviewed and approved the technical contents of Ontic Engineering and Manufacturing, Inc. Mandatory Service Bulletin (MSB) No. SB–DES– 353, Revision A, dated December 16, 2009. That MSB lists the affected propeller governors by P/N and S/N, and describes procedures for returning them to the manufacturer for repair. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. We are proposing this AD, which would require removal of affected propeller governors from service. The proposed AD would require you to use the service information described previously to identify the affected S/Ns of propeller governors. emcdonald on DSK2BSOYB1PROD with PROPOSALS Costs of Compliance We estimate that this proposed AD would affect 45 propeller governors installed on airplanes of U.S. registry. We also estimate that it would take about four work-hours per airplane to perform the proposed actions, and that the average labor rate is $85 per workhour. Required repair parts would cost about $842 per propeller governor. Based on these figures, we estimate the total cost of the proposed AD to U.S. operators to be $83,790. 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 VerDate Nov<24>2008 14:02 Mar 12, 2010 Jkt 220001 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 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 that the proposed AD: 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); and 3.

Discussion The Federal Office of Civil Aviation (FOCA), which is the aviation authority for Switzerland, has issued FOCA AD HB–2010–001, dated February 12, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: This Airworthiness Directive (AD) is prompted due to the discovery of corrosion at the bonding strap connections on the left and right lower longerons between fuselage frames 1 and 1A. The possibility of corrosion is increased because of the high electrical current flow between the tinned copper terminal lug of the bonding strap and the aluminum longeron.

In order to correct and control the situation, this AD requires a one time inspection of the longeron structure and the terminal lugs of the bonding straps for signs of corrosion. For left and right lower longerons where corrosion is found during the inspection, the MCAI also requires repair of any longeron where corrosion is found. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information PILATUS Aircraft Ltd. has issued PILATUS PC–7 Service Bulletin No. 53– 007, dated January 5, 2010. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences between this Proposed AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. Costs of Compliance We estimate that this proposed AD will affect 10 products of U.S. registry. We also estimate that it would take about 4.5 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $3,825, or $383 per product.

Discussion

    We received three reports of failure of Ontic Engineering and 
Manufacturing, Inc. propeller governors. One of the reports was of a 
Diamond DA-40 airplane losing propeller pitch control during flight. 
The propeller governor controls propeller pitch by regulating oil 
pressure to the propeller pitch change mechanism. Changes in governor 
oil pressure are made by small changes in axial displacement of the 
governor's pilot valve plunger assembly. A fly weight governor opposes 
a compressed spring that rides on a collar which forms a part of the 
pilot valve plunger assembly. Investigation revealed that the set screw 
securing the collar to the pilot valve plunger assembly shaft may not 
be installed properly on a batch of parts permitting the pilot valve 
plunger to float on the shaft. The pilot valve shaft plunger and 
captive thrust bearing are then free to move axially along the pilot 
valve shaft. When the pilot valve is unconstrained in the axial 
direction, the propeller governor cannot control oil pressure to the 
propeller pitch control mechanism. This results in a loss of propeller 
pitch control. Further, concurrent thrust bearing failure permits 
bearing debris to flow with the oil into the engine lubrication system. 
The engine in the incident airplane was internally damaged as a result 
of a

[[Page 12149]]

propeller governor bearing ball becoming lodged between the valve 
lifter and engine case. This condition, if not corrected, could result 
in loss of propeller pitch control, damage to the propeller governor, 
and internal damage to the engine, which could prevent continued safe 
flight or safe landing.

Relevant Service Information

    We have reviewed and approved the technical contents of Ontic 
Engineering and Manufacturing, Inc. Mandatory Service Bulletin (MSB) 
No. SB-DES-353, Revision A, dated December 16, 2009. That MSB lists the 
affected propeller governors by P/N and S/N, and describes procedures 
for returning them to the manufacturer for repair.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to exist or develop on other products 
of this same type design. We are proposing this AD, which would require 
removal of affected propeller governors from service. The proposed AD 
would require you to use the service information described previously 
to identify the affected S/Ns of propeller governors.

Costs of Compliance

    We estimate that this proposed AD would affect 45 propeller 
governors installed on airplanes of U.S. registry. We also estimate 
that it would take about four work-hours per airplane to perform the 
proposed actions, and that the average labor rate is $85 per work-hour. 
Required repair parts would cost about $842 per propeller governor. 
Based on these figures, we estimate the total cost of the proposed AD 
to U.S. operators to be $83,790. 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.

Regulatory Findings

    We have 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 that the proposed AD:
    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); and
    3. Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD. You may get a copy of this summary at the 
address listed under ADDRESSES.
