**ACTION :**  Notice of proposed rulemaking (NPRM).

**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


### 12467 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. 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. List of Subjects in 14 CFR Part 39

**AGENCY :**  Federal Aviation Administration (FAA), Department of Transportation (DOT).

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for all Quartz Mountain Aerospace, Inc. Model 11E airplanes. This proposed AD would require you to clean and lubricate the aileron pushrod bearings. This proposed AD results from reports of the aileron control stick force increasing and of the controls being very noisy. We are proposing this AD to detect and correct insufficient lubrication and residual metallic paint particles in the pushrod end ball joints, which could result in difficulty actuating aileron controls sometime during flight after takeoff. This condition could lead to difficulty controlling the airplane in flight.

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

**ADDRESSES :**  Use one of the following addresses to comment on this proposed AD:

• Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments. • Fax: (202) 493–2251.

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
