Federal Register / Vol. 76, No. 71 / Wednesday, April 13, 2011 / Rules and Regulations 20503 

review conducted by Fokker Services on the 

Fokker 50 and Fokker 60 in response to these 

regulations revealed that, if chafing occurs 

between the Fuel Quantity Probe (FQP) and 

the probe wiring, with additional factors, this 

may result in an ignition source in the wing 

tank vapour space. 

This condition, if not corrected, in 

combination with flammable fuel vapours, 

could result in a wing fuel tank explosion 

and consequent loss of the aeroplane. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Inspection and Installation 

(g) At a scheduled opening of the fuel 

tanks, but not later than 13 years after the 

effective date of this AD, do a general visual 

inspection for the presence of the rubber 

sleeve and cable tie on the cables of each 

FQP, in accordance with Part 1 of the 

Accomplishment Instructions of Fokker 

Service Bulletin SBF50–28–027, Revision 1, 

dated August 20, 2010. 

(h) If, during the inspection required by 

paragraph (g) of this AD, an FQP does not 

have the rubber sleeve or cable tie installed: 

Before further flight, install the rubber sleeve 

and cable tie on the affected FQP and wiring, 

in accordance with Part 2 of the 

Accomplishment Instructions of Fokker 

Service Bulletin SBF50–28–027, Revision 1, 

dated August 20, 2010. 

Maintenance Program Revision To Add Fuel 

Airworthiness Limitation 

(i) Before further flight after accomplishing 

the inspection required by paragraph (g) of 

this AD: Revise the airplane maintenance 

program by incorporating the CDCCL 

specified in paragraph 1.L.(1)(c) of Fokker 

Service Bulletin SBF50–28–027, Revision 1, 

dated August 20, 2010. 

No Alternative Actions, Intervals, and/or 

CDCCLs 

(j) After accomplishing the revision 

required by paragraph (i) of this AD, no 

alternative actions (e.g., inspection, interval) 

and/or CDCCLs may be used unless the 

actions, intervals, and/or CDCCLs are 

approved as an AMOC in accordance with 

the procedures specified in paragraph (l) of 

this AD. 

Credit for Actions Accomplished in 

Accordance With Previous Service 

Information 

(k) Actions accomplished before the 

effective date of this AD according to Fokker 

Service Bulletin SBF50–28–027, dated May 

27, 2010, are considered acceptable for 

compliance with the corresponding action 

specified in this AD. 

FAA AD Differences 

Note 1: This AD differs from the MCAI 

and/or service information as follows: 

Although EASA Airworthiness Directive 

2010–0157, dated August 3, 2010, specifies 

both revising the maintenance program to 

include airworthiness limitations, and doing 

certain repetitive actions (e.g., inspections) 

and/or maintaining CDCCLs, this AD only 

requires the revision. Requiring a revision of 

the maintenance program, rather than 

requiring individual repetitive actions and/or 

maintaining CDCCLs, requires operators to 

record AD compliance only at the time the 

revision is made. Repetitive actions and/or 

maintaining CDCCLs specified in the 

airworthiness limitations must be complied 

with in accordance with 14 CFR 91.403(c). 

Other FAA AD Provisions 

(l) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, Transport Airplane 

Directorate, FAA, has the authority to 

approve AMOCs for this AD, if requested 

using the procedures found in 14 CFR 39.19. 

In accordance with 14 CFR 39.19, send your 

request to your principal inspector or local 

Flight Standards District Office, as 

appropriate. If sending information directly 

to the International Branch, send it to ATTN:

1149. Information may be e-mailed to: 9- 

ANM-116-AMOC-REQUESTS@faa.gov. 

Before using any approved AMOC, notify 

your appropriate principal inspector, or 

lacking a principal inspector, the manager of 

the local flight standards district office/ 

certificate holding district office. The AMOC 

approval letter must specifically reference 

this AD. 

(2) Airworthy Product: For any 

requirement in this AD to obtain corrective 

actions from a manufacturer or other source, 

use these actions if they are FAA-approved. 

Corrective actions are considered FAAapproved if they are approved by the State 

of Design Authority (or their delegated

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. 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: 

It has been found occurrence of screw units 

manufactured with metallographic nonconformity that may increase their 

susceptibility to brittle fracture. The screw 

failure may result in loss of the related 

balance washer causing a possible ram air 

turbine (RAT) imbalance event, which may 

result in RAT structural failure, which 

associated with an electrical emergency 

situation, could result in loss of power to 

airplane flight controls hydraulic back-up 

system. 

* * * * * 

Loss of power to the hydraulic back-up 

system for airplane flight controls could 

reduce the ability of the flightcrew to 

maintain the safe flight and landing of 

the airplane. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on December 1, 2010 (75 FR 

74670). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

It has been found occurrence of screw units 

manufactured with metallographic nonconformity that may increase their 

susceptibility to brittle fracture. The screw 

failure may result in loss of the related 

balance washer causing a possible ram air 

turbine (RAT) imbalance event, which may 

result in RAT structural failure, which 

associated with an electrical emergency 

situation, could result in loss of power to 

airplane flight controls hydraulic back-up 

system. 

* * * * * 

Loss of power to the hydraulic back-up 

system for airplane flight controls could 

reduce the ability of the flightcrew to 

maintain the safe flight and landing of 

the airplane. Required actions include 

doing a general visual inspection to 

determine the model, part number, and 

serial number of the RAT, and to 

determine if a certain symbol is marked 

on affected RATs. Corrective actions 

include replacing the RAT balance 

screw and marking the RAT 

identification plate. You may obtain 

further information by examining the 

MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comment received. 

Request To Include Service Bulletin for 

Model ERJ 190–100 ECJ Airplanes 

EMBRAER requested that we add 

EMBRAER Service Bulletin 190LIN–24– 

0006, dated July 27, 2010, to the NPRM, 

because it applies to Model ERJ 190–100 

ECJ airplanes which are included in the 

NPRM applicability. The commenter 

requested that we change paragraphs (g), 

(h), (i), and (k) of the NPRM 

accordingly. 

We agree that EMBRAER Service 

Bulletin 190LIN–24–0006, dated July 

27, 2010, is acceptable for 

accomplishing the required actions of 

the AD for Model ERJ 190–100 ECJ 

airplanes. We have added a new 

paragraph (i) to this AD (and 

renumbered subsequent paragraphs 

accordingly) to refer to that service 

bulletin as an optional method of 

compliance for the requirements of this 

AD for those airplanes. This addition 

has been coordinated with the Ageˆncia 

Nacional de Aviac ̧a ̃o Civil (ANAC), the 

aviation authority for Brazil. 

Clarification of Terminology 

Paragraph (g)(2)(ii) of the NPRM 

specified to ‘‘replace the RAT balance 

screw with a new balance screw,’’ while 

some RATs in fact have more than one 

balance screw. We have clarified that 

instruction by stating ‘‘replace the RAT 

balance screw(s) with a new balance 

screw(s),’’ in this final rule. 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of the 

AD. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

about 241 products of U.S. registry. We 

also estimate that it will take about 9 

work-hours per product to comply with 

the basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $0 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of this AD 

to the U.S. operators to be $184,365, or 

$765 per product. 

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 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 this AD: 

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); and 

3. 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 AD: 

2011–08–08 Empresa Brasileira de 

Aeronautica S.A. (EMBRAER): 

Amendment 39–16658. Docket No. 

FAA–2010–1161; Directorate Identifier 

2010–NM–152–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective May 18, 2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to all Empresa 

Brasileira de Aeronautica S.A. (EMBRAER) 

Model ERJ 170–100 LR, –100 STD, –100 SE, 

and –100 SU airplanes; and Model ERJ 170– 

200 LR, –200 SU, and –200 STD airplanes; 

and Model ERJ 190–100 STD, –100 LR, –100 

ECJ, and –100 IGW airplanes; and Model ERJ 

190–200 STD, –200 LR, and –200 IGW 

airplanes; certificated in any category. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 24: Electrical power. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

It has been found occurrence of screw units 

manufactured with metallographic nonconformity that may increase their 

susceptibility to brittle fracture. The screw 

failure may result in loss of the related 

balance washer causing a possible ram air 

turbine (RAT) imbalance event, which may 

result in RAT structural failure, which 

associated with an electrical emergency 

situation, could result in loss of power to 

airplane flight controls hydraulic back-up 

system. 

* * * * * 

Loss of power to the hydraulic back-up 

system for airplane flight controls could 

reduce the ability of the flightcrew to 

maintain the safe flight and landing of the 

airplane. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Actions 

(g) Within 1,200 flight hours or 6 months 

after the effective date of this AD, whichever 

occurs first: Do a general visual inspection 

(GVI) to determine the RAT model, part 

number, and serial number, in accordance 

with Part 1 of the Accomplishment 

Instructions of EMBRAER Service Bulletin 

170–24–0048, Revision 01, dated May 12, 

2010; or EMBRAER Service Bulletin 190–24– 

0019, Revision 01, dated May 11, 2010; as 

applicable. A review of airplane maintenance 

records is acceptable in lieu of this 

inspection if the model, part number, and 

serial number of the RAT can be conclusively 

determined from that review. 

Note 1: For the purpose of this AD, a GVI 

is: ‘‘A visual examination of an interior or 

exterior area, installation or assembly to 

detect obvious damage, failure or irregularity. 

This level of inspection is made from within 

touching distance, unless otherwise 

specified. A mirror may be necessary to 

enhance visual access to all exposed surfaces 

in the inspection area. This level of 

inspection is made under normally available 

lighting conditions such as daylight, hangar 

lighting, flashlight or drop-light, and may 

require removal or opening of access panels 

or doors. Stands, ladders or platforms may be 

required to gain proximity to the area being 

checked.’’ 

(1) For any RAT not having a serial number 

identified in EMBRAER Service Bulletin 

170–24–0048, Revision 01, dated May 12, 

2010; or EMBRAER Service Bulletin 190–24– 

0019, Revision 01, dated May 11, 2010: No 

further action is required by this paragraph. 

(2) For any RAT having a serial number 

identified in EMBRAER Service Bulletin 

170–24–0048, Revision 01, dated May 12, 

2010; or EMBRAER Service Bulletin 190–24– 

0019, Revision 01, dated May 11, 2010: 

Within 1,200 flight hours or 6 months after 

the effective date of this AD, whichever 

occurs first, inspect to determine if the 

symbol ‘‘24–5’’ is marked on the RAT 

identification plate. A review of airplane 

maintenance records is acceptable in lieu of 

this inspection if the RAT identification plate 

can be conclusively determined to be marked 

with ‘‘24–5’’ from that review. 

(i) If the symbol ‘‘24–5’’ is marked on the 

RAT identification plate: No further action is 

required by this paragraph. 

(ii) If the symbol ‘‘24–5’’ is not marked on 

the RAT identification plate: Within 1,200 

flight hours or 6 months after the effective 

date of this AD, whichever occurs first, 

replace the RAT balance screw(s) with a new 

balance screw(s), and mark the RAT 

identification plate with the symbol ‘‘24–5,’’ 

in accordance with Part 2 of the 

Accomplishment Instructions of EMBRAER 

Service Bulletin 170–24–0048, Revision 01, 

dated May 12, 2010; or EMBRAER Service 

Bulletin 190–24–0019, Revision 01, dated 

May 11, 2010; as applicable. 

(h) As of the effective date of this AD, no 

person may install a RAT identified in Part 

1 of the Accomplishment Instructions of 

EMBRAER Service Bulletin 170–24–0048, 

Revision 01, dated May 12, 2010; or 

EMBRAER Service Bulletin 190–24–0019, 

Revision 01, dated May 11, 2010; as 

applicable; on any airplane, unless that RAT 

is identified with the symbol ‘‘24–5’’ on the 

identification plate. 

Acceptable Method of Compliance for Model 

ERJ 190–100 ECJ Airplanes 

(i) Actions accomplished in accordance 

with EMBRAER Service Bulletin 190LIN–24– 

0006, dated July 27, 2010, for Model ERJ 

190–100 ECJ airplanes, are considered 

acceptable for compliance with the 

corresponding actions specified in this AD. 

Credit for Actions Accomplished in 

Accordance With Previous Service 

Information 

(j) Actions accomplished before the 

effective date of this AD in accordance with 

EMBRAER Service Bulletins 170–24–0048 or 

190–24–0019, both dated March 31, 2010, as 

applicable, are considered acceptable for 

compliance with the corresponding actions 

specified in this AD. 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 

(1) The Brazilian ADs apply to ‘‘airplanes 

equipped with Hamilton Sundstrand ram air 

turbine (RAT), Model ERPS37T, Part Number 

(P/N) 1703781 Series; with the serial 

numbers (S/N) contained in Embraer Service 

Bulletin[s 170–24–0048 or 190–24–0019],’’ 

and their first action is an inspection to 

determine if affected equipment is installed. 

This AD applies to all of the airplanes, with 

the first action in the AD being an inspection 

to determine if affected equipment is 

installed, because the affected part could be 

rotated onto any of the airplanes listed in the 

applicability of this AD. 

(2) Although the MCAI states not to install 

the part identified in paragraph (h) of this AD 

after accomplishing the actions specified in 

paragraph (g)(2) of this AD, this AD prohibits 

installation of the part as of the effective date 

of this AD.
