Airworthiness Directives; Embraer S.A. 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2012–07– 

08, for all Embraer S.A. Model ERJ 170 

airplanes. AD 2012–07–08 currently 

requires revising the Airworthiness 

Limitations Section (ALS) of the 

Instructions for Continued 

Airworthiness (ICA) to incorporate new 

structural inspection requirements. 

Since we issued AD 2012–07–08, we 

have determined that more restrictive 

maintenance requirements and 

airworthiness limitations are necessary. 

This proposed AD would require 

revising the maintenance or inspection 

program to incorporate new inspections. 

We are proposing this AD to detect and 

correct fatigue cracking of structural 

components, which could result in 

reduced structural integrity of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by April 14, 2014.

Discussion 

On March 29, 2012, we issued AD 

2012–07–08, Amendment 39–17014 (77 

FR 24342, April 24, 2012). AD 2012–07– 

08 requires actions intended to address 

an unsafe condition on all EMBRAER 

S.A. Model ERJ 170 airplanes. (AD 

2012–07–08 superseded AD 2010–11– 

13, Amendment 39–16318 (75 FR 

30284, June 1, 2010)). 

Since we issued AD 2012–07–08, 

Amendment 39–17014 (77 FR 24342, 

April 24, 2012), the Ageˆncia Nacional 

de Aviac ̧a ̃o Civil (ANAC), which is the 

aviation authority for Brazil, has issued 

Brazilian Airworthiness Directive 2012– 

10–01, effective October 29, 2012 

(referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

This [Brazilian] AD results from a new 

revision to the Airworthiness Limitations 

Section (ALS) of Embraer ERJ 170 

Maintenance Review Board Report (MRBR 

1621), to include new or modification of the 

current tasks and its respective thresholds 

and intervals. Failure to inspect these 

structural components, according to the new 

or revised tasks, thresholds and intervals, 

could prevent a timely detection of fatigue 

cracking. These cracks, if not properly 

addressed, could adversely affect the 

structural integrity of the airplane. 

The required action is revising the 

maintenance or inspection program to 

incorporate new structural inspection 

requirements. You may examine the 

MCAI in the AD docket on the Internet 

at http://regulations.gov by searching for 

and locating it in Docket No. FAA– 

2014–0059. 

Relevant Service Information 

EMBRAER has issued Part 2— 

Airworthiness Limitation Inspection 

(ALI)—Structures, of Appendix A, 

Airworthiness Limitations of the 

EMBRAER 170 Maintenance Review 

Board MRB–1621, Revision 8, dated 

August 20, 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 This 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 the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

This proposed AD would require 

revisions to certain operator 

maintenance documents to include new 

actions (e.g., inspections). Compliance 

with these actions is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired 

in the areas addressed by this proposed 

AD, the operator may not be able to 

accomplish the actions described in the 

revisions. In this situation, to comply 

with 14 CFR 91.403(c), the operator 

must request approval for an alternative 

method of compliance according to 

paragraph (k) of this proposed AD. The 

request should include a description of 

changes to the required inspections that 

will ensure the continued operational 

safety of the airplane. 

This proposed AD would retain only 

certain paragraphs from AD 2012–07– 

08, Amendment 39–17014 (77 FR 

24342, April 24, 2012). Because all of 

the paragraphs in AD 2012–07–08 are 

not included in this proposed AD, the 

organization of the retained paragraphs 

was changed. 

Costs of Compliance 

We estimate that this proposed AD 

affects 171 products of U.S. registry. 

The actions that are required by AD 

2012–07–08, Amendment 39–17014 (77 

FR 24342, April 24, 2012), and retained 

in this proposed AD take about 1 workhour per product, at an average labor 

rate of $85 per work-hour. Required 

parts cost about $0 per product. Based 

on these figures, the estimated cost of 

the actions that were required by AD 

2012–07–08 is $85 per product. 

We also estimate that it would take 

about 1 work-hour per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $0 per product. 

Based on these figures, we estimate the 

cost of this proposed AD on U.S. 

operators to be $14,535, or $85 per 

product. 


TKELLEY on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 79, No. 39 / Thursday, February 27, 2014 / Proposed Rules 11015 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference,

Airworthiness Directives; Airbus 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directive (AD) 2007–06– 

12, that applies to certain Airbus Model 

A330–200 and A330–300 airplanes. AD 

2007–06–12 requires, for certain 

airplanes, reinforcement of the structure 

of the center fuselage by installing 

external stiffeners (butt straps) at frame 

(FR) 53.3 on the fuselage skin between 

left-hand (LH) and right-hand (RH) 

stringer (STR) 13, and related 

investigative and corrective actions. 

Since we issued AD 2007–06–12, we 

have determined that the compliance 

times must be reduced in order to 

address the unsafe condition. This 

proposed AD would reduce the 

compliance times for reinforcing the 

structure of the center fuselage at FR 

53.3. We are proposing this AD to 

prevent fatigue cracking of the fuselage, 

which could result in reduced structural 

integrity of the fuselage. 

DATES: We must receive comments on 

this proposed AD by April 14, 2014.

any of the following methods:

Discussion 

On March 7, 2007, we issued AD 

2007–06–12, Amendment 39–14993 (72 

FR 12555, March 16, 2007) (‘‘AD 2007– 

06–12’’). AD 2007–06–12 requires 

actions intended to address an unsafe 

condition on the products listed above. 

Since we issued AD 2007–06–12, 

Amendment 39–14993 (72 FR 12555, 

March 16, 2007), we have determined 

that the compliance times must be 

reduced in order to address the unsafe 

condition. We have also added the
