Start Preamble

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 Diamond Aircraft Industries GmbH Models DA40 and DA40F airplanes that would supersede AD 2013-24-14, which resulted 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 fatigue strength found in the aft main spar not ensuring unlimited lifetime structural integrity. We are issuing this proposed AD to require actions to address the unsafe condition on these products and to change the compliance time to coincide with other regulatory requirements.

DATES:

We must receive comments on this proposed AD by May 29, 2014.

Discussion

On November 22, 2013, we issued AD 2013-24-14, Amendment 39-17689 (78 FR 72568; December 3, 2013). That AD required actions intended to address an unsafe condition on Diamond Aircraft Industries GmbH Models DA40 and DA40F airplanes and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country.

The inspections required by AD 2013-24-13 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.

Relevant Service Information

Diamond Aircraft Industries GmbH has issued Mandatory Service Bulletin MSB 40-074, MSB D4-094, and MSB F4-028 (co-published as a single document), dated May 10, 2013; Diamond Aircraft Industries GmbH Work Instructions WI-MSB 40-074, WI-MSB D4-094, and WI-MSB F4-028, (co-published as a single document), dated May 10, 2013; and DA 40 Series AMM, Chapter Section 05-28-50, Section 2 (Cockpit), page 11, Item 31, sub-item “The rear main bulkhead,” Rev. 7, dated April 1, 2013. 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.

Costs of Compliance

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

Based on these figures, we estimate the cost of the proposed AD on 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 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 proposed 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),

(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.

(g) Other FAA AD Provisions

The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Mike Kiesov, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4144; fax: (816) 329-4090; email: mike.kiesov@faa.gov.
