Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

We are adopting a new airworthiness directive (AD) for Diamond Aircraft Industries Model DA 40 NG airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as chafing between the charge air tubing and the engine firewall that may cause a hole in the charge air tubing, which could result in loss of charged air pressure with consequent loss of engine power and loss of control. We are issuing this AD to require actions to address the unsafe condition on these products.

DATES:

This AD is effective May 21, 2013.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of May 21, 2013.

We must receive comments on this AD by June 17, 2013.

SUPPLEMENTARY INFORMATION:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2013-0018, dated January 21, 2013 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

An occurrence of loss of engine charge air pressure was reported, which prompted an in-flight Engine Control Unit warning. The investigation results identified that chafing caused a hole in the charge air tubing where it touched the engine firewall. Further investigation results identified other DA 40 NG aeroplanes with chafing marks in this area.

To prevent chafing between the charged air tube and engine firewall, DAI issued Recommended SB 40NG-011 to replace the charged air elbow hose between the turbocharger and intercooler with an aluminium tube to improve the durability of the charged air system.

After issuance of SB 40NG-011, an additional occurrence of a hole in a charge air tube was reported, apparently caused by chafing. The results of the subsequent investigation revealed that the improved design cannot assure the necessary clearance between the charged air tubing and surrounding parts.

This condition, if not corrected, could lead to loss of charged air pressure, possibly resulting in loss of engine power and reduced control of the aeroplane.

To address this unsafe condition, DAI issued Mandatory SB 40NG-18, providing instructions to inspect the charged air tubing from the turbocharger to the intercooler and replacement of affected parts with an improved design.

For the reasons described above, this AD requires repetitive inspections of charged air tubing for the presence of the chafing marks and, depending on findings, replacement of damaged tubing, or installation of improved design tubing.

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

Relevant Service Information

Diamond Aircraft Industries GmbH has issued Mandatory Service Bulletin 40NG-018/1, dated November 20, 2012. 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 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 issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because there is only one airplane on the U.S. registry affected by this unsafe condition, and the required modification has been completed on the specific airplane. Therefore, we determined that notice and opportunity for public comment before issuing this AD are unnecessary and that good cause exists for making this amendment effective in fewer than 30 days.Start Printed Page 25364

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2013-0348; Directorate Identifier 2013-CE-005-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.

We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

Costs of Compliance

We estimate that this AD will affect 1 product 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 AD. The average labor rate is $85 per work-hour. Required parts would cost about $1,381 per product.

Based on these figures, we estimate the cost of the AD on U.S. operators to be $1,551, or $1,551 per product.

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 AD will not have federalism implications under Executive Order 13132. This AD will 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 this 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),

(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.
