(c) Applicability

This AD applies to DORNIER LUFTFAHRT GmbH Model 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 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 improper restoration of corrosion protection as the likely cause of initial fatigue cracking of the main landing gear (MLG) axle. 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) and (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 April 1, 2014 (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 10 years old or is more than 10 years old: Within the next 400 hours TIS after April 1, 2014 (the effective date of this AD) or within the next 6 months after April 1, 2014 (the effective date of this AD), whichever occurs first.

(ii) If, as of April 1, 2014 (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 April 1, 2014 (the effective date of this AD), whichever occurs first.

(2) If, during the inspection required in paragraph (f)(1) of this AD, any discrepancies are found outside the limits 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.

**SUPPLEMENTARY INFORMATION**

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. The NPRM published in the Federal Register on September 26, 2013 (78 FR 59304). The NPRM was prompted by reports of chaffing, arcing, and burning damage to the control cabin overhead wiring and ducting with smoke and fire caused by metal clamps installed on certain hoses. The NPRM proposed to require inspecting for the presence of metal clamps, replacing metal clamps installed on the hoses to the air conditioning temperature sensor, gasper air outlet, and diffuser on the left side of the control cabin with plastic tie straps, and inspecting for and repairing damaged wire bundles. We are issuing this AD to correct incorrectly installed metal clamps, which could cause wire bundle damage and electrical arcing that could result in a fire or smoke in the control cabin of the airplane.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the proposal (78 FR 59304, September 26, 2013) and the FAA’s response to that comment. Statement of Supplemental Type Certificate (STC) Effect on Applicability

Aviation Partners Boeing stated that the installation of winglets per STC ST01219SE ( http://rgl.faa.gov/ Regulatory

_ and

_ Guidance

_Library/ rgstc.nsf/0/BE866B732 F6CF31086257B9700692796? OpenDocument&Highlight=st01219se ) does not affect the accomplishment of the proposed requirements.

We have re-designated paragraph (c) of the NPRM (78 FR 59304, September 26, 2013) as paragraph (c)(1) in this final rule and added new paragraph (c)(2) to this final rule to state that installation of STC ST01219SE ( http://rgl.faa.gov/ Regulatory

_ and

_ Guidance

_ Library/ rgstc.nsf/0/BE866B732F6CF31086257 B9700692796?OpenDocument& Highlight=st01219se ) does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01219SE is installed, a ‘‘change in product’’ alternative method of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17.

Conclusion

We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD with the change described previously and minor editorial changes. We have determined that these minor changes:

• A re consistent with the intent that was proposed in the NPRM (78 FR 59304, September 26, 2013) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 59304, September 26, 2013).

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Costs of Compliance

We estimate that this AD affects 426 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:



### E STIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Inspection and Replacement. 2 work-hours × $85 per hour = $170 per replacement. $0 $170 per replacement ...... $72,420



### We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD. 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

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 that this AD:

(1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866,


## 10352 Federal Register / Vol. 79, No. 37 / Tuesday, February 25, 2014 / Rules and Regulations

(2) Is not a ‘‘significant rule’’ under 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. 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**

**§ 39.13 [Amended]**

■ 

### 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):
2014–04–05 The Boeing Company: Amendment 39–17763 ; Docket No. FAA–2013–0831; Directorate Identifier 2013–NM–125–AD.
(a) Effective Date
