DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2014-0226; Directorate Identifier 2014-CE-009-AD; 
Amendment 39-17884; AD 2014-13-08]
RIN 2120-AA64

Airworthiness Directives; Diamond Aircraft Industries GmbH 
Airplanes

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).

ADDRESSES: 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, U.S. Department

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

[[Page 42648]]

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 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

     Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Amendment 39-17689 (78 FR 
72568; December 3, 2013) and adding the following new AD:

2014-13-08 Diamond Aircraft Industries GmbH: Amendment 39-17884; 
Docket No. FAA-2014-0226; Directorate Identifier 2014-CE-009-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective August 27, 
2014.

(b) Affected ADs

    This AD supersedes AD 2013-24-14, Amendment 39-17689 (78 FR 
72568; December 3, 2013).

(c) Applicability

    This AD applies to Diamond Aircraft Industries Model DA 40 
airplanes, serial numbers 40.006 through 40.009, 40.011 through 
40.1071, and 40.1073 through 40.1077; and Model DA 40 F airplanes, 
serial numbers 40.FC001 through 40.FC029; certificated in any 
category.

(d) Subject

    Air Transport Association of America (ATA) Code 57: Wings.

(e) Reason

    This AD was prompted by 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 fatigue 
strength found in the aft main spar not ensuring unlimited lifetime 
structural integrity. We are issuing this AD to correct an incorrect 
compliance time and to modify the aft main spar in the cabin area to 
ensure the structural integrity of the airplane.
