Supplemental notice of proposed rulemaking (NPRM); reopening of the comment period.
We are revising an earlier NPRM 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.
We must receive comments on this proposed AD by April 18, 2014.

We proposed to amend 14 CFR part 39 with an NPRM for DORNIER LUFTFAHRT GmbH Models Dornier 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212 airplanes, which was published in the Federal Register on December 23, 2013 (78 FR 77380), and proposed to supersede AD 2006-11-19, Amendment 39-14624 (71 FR 32268; June 5, 2006). The NPRM proposed to require actions intended to address the unsafe condition for the products listed above and was based on mandatory continuing airworthiness information (MCAI) originated by another country. The MCAI states that:
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 Start Printed Page 12132respectively TM-TLMCM-228-00002-150610) for zone 321 overhead panels 5VE/6VE.
The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2013-1056-0002.
Since that NPRM was issued, we identified that we inadvertently omitted the calendar time compliance for the inspections of the wiring in the flight deck overhead panels. Because the compliance time is based on “whichever occurs first,” adding the calendar time with the hours time-in-service potentially increases the burden on the public.
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.
We did not receive any comments on the earlier NPRM.
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.
Certain changes described above expand the scope of the earlier NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on the proposed AD.
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.
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 on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

2. The FAA amends § 39.13 by adding the following new AD: End Amendment Part
Dornier Luftfahrt GmbH: Docket No. FAA-2013-1056; Directorate Identifier 2013-CE-046-AD.
(a) Comments Due Date
We must receive comments by April 18, 2014.
(b) Affected ADs
This AD supersedes AD 2006-11-19, Amendment 39-14624 (71 FR 32268; June 5, 2006).
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.
Air Transport Association of America (ATA) Code 5: Time Limits.
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 or within the next 12 months after the effective date of this AD, whichever occurs first, and repetitively thereafter at intervals not to exceed 600 hours TIS or 12 months, whichever occurs first, inspect the wiring in the flight deck overhead panels, 5VE and 6VE, for chafing, damage, and/or incorrect installation (wire tie attachment holders). For the inspection, refer to zone 321 on page 5 in the Zonal Inspection Program in section 05-22-10 and zone 321 on page 5 in the Low Utilization Zonal Inspection Program in section 05-26-10 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-Start Printed Page 1213310-07 and 31-10-08, both 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, both 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.
