Airworthiness Directives; DORNIER LUFTFAHRT GmbH Airplanes

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 
DORNIER LUFTFAHRT GmbH Model 228-212 airplanes. 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 main landing gear axle failure caused by 
initial fatigue cracking and small pre-damage by corrosion. We are 
issuing this proposed AD to require actions to address the unsafe 
condition on these products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No.: 2013-0209, dated September 10, 2013 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

An event of a main landing gear (MLG) axle break during touchdown 
has been reported. The results of the subsequent technical 
investigation indicated that improper restoration of corrosion 
protection was the likely cause of the initial fatigue cracking.
    This condition, if not detected and corrected, could lead to 
failure of the main landing gear axle, possibly resulting in a 
runway excursion with consequent damage to the aeroplane and injury 
to the occupants.
    To address this potential unsafe condition, RUAG Aerospace 
Services GmbH issued Service Bulletin (SB) SB-228-300, Rev. 1.
    For the reason described above, this AD requires a one-time 
inspection of the MLG axle and, depending on findings, 
accomplishment of applicable corrective actions.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-
2013-0962.

Relevant Service Information

    RUAG Aerospace Services GmbH has issued Dornier 228 Service 
Bulletin No. SB-228-300, Revision 1, dated April 25, 2013. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI.

[[Page 69321]]

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 would affect 2 products of U.S. 
registry. We also estimate that it would take about 160 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 $27,200, or $13,600 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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 adding the following new AD:

Dornier Luftfahrt GmbH: Docket No. FAA-2013-0962; Directorate 
Identifier 2013-CE-028-AD.

(a) Comments Due Date

    We must receive comments by January 3, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to DORNIER LUFTFAHRT GmbH 228-212 airplanes, all 
serial numbers, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 32: Landing 
Gear.

(e) Reason

    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. This AD was prompted by a report of a main landing gear 
axle failure caused by initial fatigue cracking and detection of 
small pre-damage by corrosion. We are issuing this AD to detect and 
correct possible corrosion and cracking of the MLG axle, which could 
lead to failure of the MLG axle resulting in a runway excursion with 
consequent damage to the airplane and injury to the occupants.

(f) Actions and Compliance

    Unless already done, do the actions in paragraphs (f)(1) through 
(f)(2) of this AD:
    (1) Inspect the MLG axle following the Accomplishment 
Instructions in RUAG Aerospace Services GmbH Dornier 228 Service 
Bulletin No. SB-228-300, Revision 1, dated April 25, 2013, at the 
time specified in paragraphs (f)(1)(i) or (f)(1)(ii) of this AD.
    (i) If, as of the effective date of this AD, the main landing 
gear (MLG) has 6,000 or more hours time-in-service (TIS) since new 
or is more than 10 years old: Within the next 400 hours TIS after 
the effective date of this AD or within the next 6 months after the 
effective date of this AD, whichever occurs first.
    (ii) If, as of the effective date of this AD, the MLG has less 
than 6,000 hours TIS since new or is between 5 to 10 years old: 
Before or upon accumulating 6,400 hours TIS or within 6 months after 
the effective date of this AD, whichever occurs first.
    (2) If, during the inspections required in paragraph (f)(1) of 
this AD, any discrepancies are found outside the limits as specified 
in RUAG Aerospace Services GmbH Dornier 228 Service Bulletin No. SB-
228-300, Revision 1, dated April 25, 2013, before further flight, 
make all necessary corrective actions following the Accomplishment 
Instructions in RUAG Aerospace Services GmbH Dornier 228 Service 
Bulletin No. SB-228-300, Revision 1, dated April 25, 2013.
