AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

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: 

Periodic operational check of the firewall 

hydraulic shutoff valves [FWSOV], made 

during routine maintenance, has revealed 

that the failure rate of that component is 

significantly higher than expected. Such a 

dormant failure, when combined with further 

possible failures, such as engine fire, may 

lead to an unacceptable reduction of safety 

margins. 

The unsafe condition is failure of the 

firewall hydraulic shutoff valve, which, 

in combination with an engine fire, 

could result in the spread of an engine 

fire beyond the firewall. We are issuing 

this AD to require actions to correct the 

unsafe condition on these products. 

DATES: This AD becomes effective May 

19, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of May 19, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (NPRM) to amend 

14 CFR part 39 to include an AD that 

would apply to the specified products. 

That supplemental NPRM was 

published in the Federal Register on 

June 26, 2008 (73 FR 36290). That 

supplemental NPRM proposed to 

correct an unsafe condition for the 

specified products. 

Since that NPRM was issued, Ageˆncia 

Nacional de Aviac ̧a ̃o Civil (ANAC), 

which is the aviation authority for 

Brazil, has issued Brazilian 

Airworthiness Directives 2007–02– 

01R2, and 2007–02–02R2, both effective 

July 17, 2009. The revised MCAI 

references suitable hydraulic shutoff 

valves for replacement valves. (This 

change is explained further in a 

comment from EMBRAER, which is 

discussed below.) The MCAI states: 

Periodic operational check of the firewall 

hydraulic shutoff valves [FWSOV], made 

during routine maintenance, has revealed 

that the failure rate of that component is 

significantly higher than expected. Such a 

dormant failure, when combined with further 

possible failures, such as engine fire, may 

lead to an unacceptable reduction of safety 

margins. 

The unsafe condition is failure of the 

firewall hydraulic shutoff valve, which, 

in combination with an engine fire, 

could result in the spread of an engine 

fire beyond the firewall. The MCAI 

requires repetitive operational checks of 

the firewall hydraulic shutoff valve, and 

if necessary, replacement of the valve. 

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 comments received. 

Request To Revise Unsafe Condition 

Statement 

EMBRAER requests that we revise the 

description of the unsafe condition. 


jlentini on DSKJ8SOYB1PROD with RULES
19194 Federal Register / Vol. 75, No. 71 / Wednesday, April 14, 2010 / Rules and Regulations 

EMBRAER explains that loss of 

hydraulic pressure, as stated in the 

supplemental NPRM, is an expected 

result when the firewall hydraulic 

shutoff valves fail to close when 

commanded to close. The failure mode 

for the valve results in the valve not 

closing when commanded to close. 

When the valve does not close, then a 

fire can spread beyond the firewall. 

We agree to revise the unsafe 

condition statement to remove the 

phrase ‘‘loss of hydraulic pressure,’’ and 

have revised the statements in the 

preamble and paragraph (e) of the AD 

accordingly. 

Request To Add an Optional 

Terminating Action 

EMBRAER also requests that we add 

replacing an affected valve with a new 

valve, P/N 975287–7, as an optional 

terminating action for the 600-flighthour-interval inspections required by 

paragraph (f) of the supplemental 

NPRM. EMBRAER adds that a service 

bulletin to install this new valve should 

be issued soon. 

We agree to add the replacement 

discussed by the commenter as an 

optional terminating action. We 

received new service bulletins, 

EMBRAER Service Bulletin 190–29– 

0021 and 170–29–0024, both dated 

December 22, 2008, that describe 

replacement instructions for the valves 

and explain that replacement with P/N 

975287–7 returns the repetitive interval 

to the original 3,000 flight hours 

specified in the relevant maintenance 

review board report. We also received 

revised Brazilian ADs 2007–02–01R2 

and 2007–02–02R2, both effective July 

17, 2009, which provide for the use of 

other valves bearing a new part number 

in replacing faulty valves. We have 

added paragraph (f)(2) to this AD to 

provide an optional terminating action 

for the requirements of paragraph (f)(1) 

of this AD. We have also re-identified 

paragraph (f) of the supplemental NPRM 

as paragraph (f)(1) of this AD. 

Revision to Paragraph (f)(1) of This AD 

We have revised the language in 

paragraph (f)(1) of this AD from ‘‘If the 

valve does not operate properly, * * *’’ 

to ‘‘If the valve fails the operational test,’’ 

as described in the applicable service 

bulletin listed in Table 1 of this AD. 

This change more closely aligns with 

the phrasing used in the MCAI 

referenced in this AD. 

Explanation of Changes to Applicability 

We have revised the applicability of 

the supplemental NPRM to clarify 

affected airplane categories and identify 

model designations as published in the 

most recent type certificate data sheet 

(TCDS) for the affected models. Since 

we issued the original NPRM, the Model 

ERJ 190–100 ECJ airplane was added to 

the U.S. TCDS. This model is also 

affected by the identified unsafe 

condition. There are no airplanes of this 

model currently registered in the United 

States. 

Conclusion 

We reviewed the available data, 

including the comments 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. 

Explanation of Change to Costs of 

Compliance 

Since issuance of the supplemental 

NPRM, we have increased the labor rate 

used in the Costs of Compliance from 

$80 per work-hour to $85 per workhour. The Costs of Compliance 

information, below, reflects this 

increase in the specified hourly labor 

rate. 

Costs of Compliance 

We estimate that this AD will affect 

145 products of U.S. registry. We also 

estimate that it will take about 1 workhour per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost of this AD to the U.S. operators to 

be $12,325, or $85 per product, per 

inspection cycle. 

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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

section. Comments will be available in 

the AD docket shortly after receipt.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 


jlentini on DSKJ8SOYB1PROD with RULES
Federal Register / Vol. 75, No. 71 / Wednesday, April 14, 2010 / Rules and Regulations 19195 

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: 

2010–08–02 Empresa Brasileira de 

Aeronautica S.A. (EMBRAER): 

Amendment 39–16257. Docket No. 

FAA–2007–28377; Directorate Identifier 

2007–NM–063–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective May 19, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Empresa Brasileira 

de Aeronautica S.A. (EMBRAER) Model ERJ 

170–100 LR, –100 STD, –100 SE, –100 SU, 

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

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

IGW, –100 ECJ, –200 STD, –200 LR, and –200 

IGW airplanes; certificated in any category; 

equipped with firewall hydraulic shutoff 

valves having part number (P/N) 975287–3 or 

P/N 975287–5. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 29: Hydraulic power. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

Periodic operational check of the firewall 

hydraulic shutoff valves [FWSOV], made 

during routine maintenance, has revealed 

that the failure rate of that component is 

significantly higher than expected. Such a 

dormant failure, when combined with further 

possible failures, such as engine fire, may 

lead to an unacceptable reduction of safety 

margins. 

The unsafe condition is failure of the firewall 

hydraulic shutoff valve, which, in 

combination with an engine fire, could result 

in the spread of an engine fire beyond the 

firewall. The MCAI requires repetitive 

operational checks of the firewall hydraulic 

shutoff valve, and if necessary, replacement 

of the valve. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) Within the next 600 flight hours after 

the effective date of this AD, perform an 

operational test for proper operation of the 

firewall hydraulic shutoff valves P/N 

975287–3 or P/N 975287–5, as applicable, in 

accordance with the applicable service 

bulletin listed in Table 1 of this AD. If the 

valve fails the operational test, as described 

in the applicable service bulletin listed in 

Table 1 of this AD, before further flight, 

replace the faulty hydraulic shutoff valve 

with another one bearing P/N 975287–3 or P/ 

N 975287–5. Repeat the test thereafter at 

intervals that do not exceed 600 flight hours. 

Note 1: For the purpose of this AD, an 

operational test is: ‘‘A task to determine that 

an item is fulfilling its intended purpose. The 

test does not require quantitative tolerances. 

This is a failure finding task.’’

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: 

During a recent in-service event the flight 

crew of a Trent 700 powered A330 aircraft 

reported a temporary Engine Pressure Ratio 

(EPR) shortfall on engine 2 during the takeoff phase of the flight.* * * 

Data analysis confirmed a temporary fuel 

flow restriction and subsequent recovery, and 

indicated that also engine 1 experienced a 

temporary fuel flow restriction shortly after 

the initial event on engine 2. * * * 

Based on previous industry-wide 

experience, the investigation of the event has 

focused on the possibility for ice to 

temporarily restrict the fuel flow.* * * 

* * * * * 

The scenario of ice being shed and causing 

a temporary blockage in the engine fuel 

system may lead to a temporary fuel flow 

restriction to the engine. This may result in 

a possible engine surge or stall condition, 

and in the engine not being able to provide 

the commanded thrust.

This AD requires actions that are 

intended to address the unsafe 

condition described in the MCAI.
