10350 Federal Register / Vol. 79, No. 37 / Tuesday, February 25, 2014 / Rules and Regulations 

(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

(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

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,

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: 

• Are 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: 

ESTIMATED 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, 


tkelley on DSK3SPTVN1PROD with RULES
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 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 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 

This AD is effective April 1, 2014. 

(b) Affected ADs 

None. 

(c) Applicability 

(1) This AD applies to The Boeing 

Company Model 737–100, –200, –200C, 

–300, –400, and –500 series airplanes, 

certificated in any category, as identified in 

Boeing Service Bulletin 737–21–1186, dated 

April 17, 2012. 

(2) Installation of Supplemental Type 

Certificate (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.
