AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2013-24-14 for Diamond Aircraft Industries GmbH Models DA40 and DA40F airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 fatigue strength found in the aft main spar not ensuring unlimited lifetime structural integrity. We are issuing this AD to require actions to address the unsafe condition on these products.

DATES:

This AD is effective August 27, 2014.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of August 27, 2014.

The Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD as of January 7, 2014 (78 FR 72568; December 3, 2013).

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to add an AD that would apply to Diamond Aircraft Industries GmbH Model DA 40 airplanes. That NPRM was published in the Federal Register on April 14, 2014 (79 FR 20827), and proposed to supersede AD 2013-24-14, Amendment 39-17689 (78 FR 72568; December 3, 2013) (“AD 2013-24-14”).

Since we issued AD 2013-24-14, the inspections required by AD 2013-24-14 are tied to calendar time and the major structural inspection (MSI) identified in Chapter 5 of the airplane maintenance manual (AMM). This compliance time mirrors the mandatory continuing airworthiness information (MCAI) issued by the State of Design for these products. However, U.S. operators are not required to comply with the requirement to inspect before the next MSI since the Limitations in Chapter 4 of the AMM are mandatory, and the MSI in Chapter 5 of the AMM is not mandatory.

The NPRM proposed to correct an unsafe condition for the specified products and was based on MCAI originated by an aviation authority of another country. The MCAI states that:

Structural fatigue testing of the DA 40 aeroplane carried out for an extension of the Major Structural Inspection (MSI) interval has shown that the fatigue strength of the aft main spar in the cabin area does not ensure unlimited lifetime.

This condition, if not corrected, could adversely affect the structural integrity of the aeroplane.

Diamond Aircraft Industries (DAI) issued Mandatory Service Bulletin (MSB) 40-074/MSB D4-094/MSB F4-028, including Work Instruction (WI) WI-MSB 40-074/WI-MSB D4-094/WI-MSB F4-028 (published as a single document), providing instructions to reinforce the aft main spar in the cabin area.

For the reasons described above, this AD requires modification of the aft main spar in the cabin area.

The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/​#!documentDetail;​D=​FAA-2014-0226-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 20827, April 14, 2014) or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM (79 FR 20827, April 14, 2014) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 20827, April 14, 2014).

Costs of Compliance

We estimate that this AD will affect 747 products of U.S. registry. We also estimate that it will take about 6 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $100 per product.

Based on these figures, we estimate the cost of this AD to the U.S. operators to be $455,670, or $610 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 Start Printed Page 42648detail 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 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.

Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2014-0226; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
