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 
Dornier Luftfahrt GmbH Models Dornier 228-100, 228-101, 228-200, 228-
201, 228-202, and 228-212 airplanes that would supersede AD 2006-11-19. 
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 chafed or damaged 
wiring on the flight deck overhead panels (5VE and 6VE). We are issuing 
this proposed AD to require actions to address the unsafe condition on 
these products.

Discussion

    On May 24, 2006, we issued AD 2006-11-19, Amendment 39-14624 (71 FR 
32268; June 5, 2006). That AD required actions intended to address an 
unsafe condition on the products listed above.
    Since we issued AD 2006-11-19 (71 FR 32268; June 5, 2006), Dornier 
Luftfahrt GmbH changed the compliance time between repetitive 
inspections and incorporated those inspections into the Time Limits/
Maintenance Checks Manual (TLMCM).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2013-0244, dated October 4, 2013 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    RUAG Aerospace Services GmbH issued Time Limits/Maintenance 
Checks Manual (TLMCM) TM-TLMCM-090305-ALL, Revision 5 dated 20 March 
2011 respectively TM-TLMCM-228-00002-150610, Revision 1 dated 03 
March 2011, listing component life limits and describing maintenance 
instructions for the Dornier 228 type design. The Document TM-TLMCM-
228-00002-150610 is valid for airplane SN 8300 and up and other 
airplane SN modified according to CN-228-247. The instructions 
contained in that manual have been identified as mandatory actions 
for continued airworthiness.
    In 2005, chafed wiring was found on 5VE Panel due to lost 
adhesive of the TY-RAP holder and subsequent vibration of the cable 
harness.
    To address this potential unsafe condition, RUAG issued All 
Operators Telefax (AOT) No. AOT-228-24-028 and Temporary Revision 
(TR) 05-05 of the TLMCM introducing repetitive of the cockpit 
overhead panels 5VE and 6VE and, depending on findings, corrective 
actions(s). Subsequently, LBA issued AD D-2005-438 (EASA approval 
2005-6430) to require those actions.
    Since that AD was issued, the instructions of TR 05-05 have been 
incorporated into TM-TLMCM-090305-ALL, Revision 5 dated 20 March 
2011 respectively into TM-TLMCM-228-00002-150610, Revision 1 dated 
03 March 2011.
    For the reasons described above, this AD retains the 
requirements of EASA AD D-2005-438, which is superseded, and 
requires the implementation of the life limits and maintenance 
actions as specified in the TLMCM (TM-TLMCM-090305-ALL respectively 
TM-TLMCM-228-00002-150610) for zone 321 overhead panels 5VE/6VE.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-
2013-1056.

Relevant Service Information

    Dornier Luftfahrt GmbH has issued RUAG Aerospace Services GmbH 
Dornier 228 TLMCM, TM-TLMCM-090305-ALL, Revision 5, March 20, 2011; and 
RUAG Aerospace Services GmbH Dornier 228 Airplane Maintenance Manual, 
TM-AMM-228-00014-080184, Revision 3, October 30, 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 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 17 products 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 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 $2,890 or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 3 work-hours and require parts costing $1,000, for a cost of 
$1,255 per product. We have no way of determining the number of 
products that may need these actions.

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 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.

Identifier 2013-CE-046-AD.

(a) Comments Due Date

    We must receive comments by February 6, 2014.

(b) Affected ADs

    This AD supersedes AD 2006-11-19, Amendment 39-14624 (71 FR 
32268; June 5, 2006).

[[Page 77382]]

(c) Applicability

    This AD applies to Dornier Luftfahrt GmbH Dornier Models 228-
100, 228-101, 228-200, 228-201, 228-202, and 228-212 airplanes, all 
serial numbers, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 5: Time Limits.

(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 chafed or 
damaged wiring on the flight deck overhead panels (5VE and 6VE). We 
are issuing this AD to prevent chafing and damage to the wiring in 
the flight deck overhead panels, which could result in short-
circuiting of related wiring and possibly lead to electrical failure 
of affected systems and potential fire in the flight deck.

(f) Actions and Compliance

    Unless already done, do the following actions in paragraphs 
(f)(1) through (f)(3) of this AD:
    (1) Within the next 600 hours time-in-service (TIS) after the 
effective date of this AD and repetitively thereafter at intervals 
not to exceed 600 hours TIS, inspect the wiring in the flight deck 
overhead panels, 5VE and 6VE, for chafing, damage, and/or incorrect 
installation (wire tie attachment holders) following the Zonal 
Inspection Program for zone 321 in section 5-22-10 of Chapter 05 in 
RUAG Aerospace Services GmbH Dornier 228 Time Limits/Maintenance 
Checks Manual (TLMCM), TM-TLMCM-090305-ALL, Revision 5, March 20, 
2011; and subjects 31-10-07 and 31-10-08, dated November 25, 2009, 
of Chapter 31, Indicating/Recording Systems in RUAG Aerospace 
Services GmbH Dornier 228 Airplane Maintenance Manual, TM-AMM-228-
00014-080184, Revision 3, October 30, 2012.
    (2) If any chafed or damaged wires are found during any 
inspection required in paragraph (f)(1) of this AD, before further 
flight, repair the affected wire(s) and assure correct installation 
of the wiring in the flight deck overhead panels by reattaching or 
replacing the wire tie attachment holders and securing any loose 
wires to the wire tie attachment holders with plastic wire ties 
following subjects 31-10-07 and 31-10-08, dated November 25, 2009, 
of Chapter 31, Indicating/Recording Systems in RUAG Aerospace 
Services GmbH Dornier 228 Airplane Maintenance Manual, TM-AMM-228-
00014-080184, Revision 3, October 30, 2012.
    (3) To comply with the actions of this AD, you may insert a copy 
of this AD or a copy of the required actions of this AD into the 
airworthiness limitations section of the FAA-approved maintenance 
program (e.g., maintenance manual). This action may be done by an 
owner/operator (pilot) holding at least a private pilot certificate 
and must be entered into the airplane records showing compliance 
with this AD in accordance with 14 CFR 43.9 (a)(1)(4) and 14 CFR 
91.417(a)(2)(v). The record must be maintained as required by 14 CFR 
91.173 or 135.439.

(g) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager,
