This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of VerDate Nov<24>2008 15:10 Mar 15, 2010 Jkt 220001 Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2010–0260; Directorate Identifier PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 2010–CE–015–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2009– 0279, dated December 23, 2009 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: The manufacturer has received a report of a failed canopy jettison test, during a regular maintenance check. The investigation revealed that a cable shroud of the jettison system protruded the canopy structure, which probably caused the malfunction. Inability to jettison the canopy in flight would prevent evacuation of the aeroplane in case of need. For the reason stated above, this AD mandates an additional one time canopy jettison test and repair if necessary. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Grob Aircraft AG has issued Service Bulletin No. MSB1078–164, dated July 21, 2009. 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 E:\FR\FM\16MRP1.SGM 16MRP1 Federal Register / Vol. 75, No. 50 / Tuesday, March 16, 2010 / Proposed Rules 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. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD. emcdonald on DSK2BSOYB1PROD with PROPOSALS-1 Costs of Compliance We estimate that this proposed AD will affect 3 products of U.S. registry. We also estimate that it would take about 2 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 $510 or $170 per product. In addition, we estimate that any necessary follow-on actions would take about 3 work-hours and require parts costing $68, for a cost of $323 per product. We have no way of determining the number of products that may need these actions. 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 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 VerDate Nov<24>2008 15:10 Mar 15, 2010 Jkt 220001 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); and 3. 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Discussion We have received reports of the aileron control stick force increasing and of the controls being very noisy on Quartz Mountain Aerospace, Inc. Model 11E airplanes. This condition may not be detectable before takeoff. In one actual instance, the condition occurred during flight. The stick force increased after preflight inspection and after takeoff. The airplane was operated by a student pilot, who had trouble flying the airplane when this occurred, and the certified flight instructor (CFI) had to take control and land the airplane. Lubricating the rod end removed the condition. Inspection revealed the left and right aileron push rod forward ends at the bellcrank were dry due to no lubrication. Further examination of the pushrod end ball joint hardware by the manufacturer found that the ball joint surfaces were additionally contaminated with specks of metallic paint as well as not being lubricated. A review of manufacturer build procedures found airplane painting with the rod ends exposed. Production procedures were changed to prevent further contamination. This condition, if not corrected, could lead to difficulty controlling the airplane in flight. Relevant Service Information We have reviewed Quartz Mountain Aerospace Service Bulletin No. SB 09– 02, dated May 5, 2009. The service information describes procedures for cleaning and lubricating the aileron pushrod bearings. FAA’s Determination and Requirements of the Proposed AD We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would require you to clean and lubricate the aileron pushrod bearings. Costs of Compliance We estimate that this proposed AD would affect 12 airplanes in the U.S. registry. We estimate the following costs to do the proposed cleaning and lubrication: Labor cost Parts cost Total cost per airplane Total cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $10 $95 $1,140 VerDate Nov<24>2008 15:10 Mar 15, 2010 Jkt 220001 PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 E:\FR\FM\16MRP1.SGM 16MRP1

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as: The manufacturer has received a report of a failed canopy 
jettison test, during a regular maintenance check. The investigation 
revealed that a cable shroud of the jettison system protruded the 
canopy structure, which probably caused the malfunction. Inability to 
jettison the canopy in flight would prevent evacuation of the aeroplane 
in case of need.
    The proposed AD would require actions that are intended to address 
the unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by April 30, 2010.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2009-0279, dated December 23, 2009 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    The manufacturer has received a report of a failed canopy 
jettison test, during a regular maintenance check. The investigation 
revealed that a cable shroud of the jettison system protruded the 
canopy structure, which probably caused the malfunction. Inability 
to jettison the canopy in flight would prevent evacuation of the 
aeroplane in case of need.
    For the reason stated above, this AD mandates an additional one 
time canopy jettison test and repair if necessary.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Grob Aircraft AG has issued Service Bulletin No. MSB1078-164, dated 
July 21, 2009. 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

[[Page 12467]]

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.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    We estimate that this proposed AD will affect 3 products of U.S. 
registry. We also estimate that it would take about 2 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 $510 or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 3 work-hours and require parts costing $68, for a cost of 
$323 per product. We have no way of determining the number of products 
that may need these actions.

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 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); and
    3. 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

    The manufacturer has received a report of a failed canopy 
jettison test, during a regular maintenance check. The investigation 
revealed that a cable shroud of the jettison system protruded the 
canopy structure, which probably caused the malfunction. Inability 
to jettison the canopy in flight would prevent evacuation of the 
aeroplane in case of need.

    For the reason stated above, this AD mandates an additional one-
time canopy jettison test and repair if necessary.
