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) 

issued by an airworthiness authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

During production quality inspections of 

the aeroplane fuel motive flow system, it was 

discovered that some motive flow check 

valves (MFCV) were manufactured with an 

outlet fitting containing red anodized 

threads. These MFCV do not provide 

adequate electrical bonding between the 

valve and the adjacent fitting. 

In the absence of proper electrical bonding 

within the motive flow system, the aeroplane 

fuel tank could be exposed to ignition 

sources in the case of a lightning strike. 

* * * * * 

The unsafe condition is the potential for 

ignition sources inside the fuel tanks, 

which, in combination with flammable 

fuel vapors, could result in a fuel tank 

explosion and consequent loss of the 

airplane. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective June 

22, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of June 22, 2011.

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 February 23, 2011 (76 FR 

9982). The MCAI states: 

During production quality inspections of 

the aeroplane fuel motive flow system, it was 

discovered that some motive flow check 

valves (MFCV) were manufactured with an 

outlet fitting containing red anodized 

threads. These MFCV do not provide 

adequate electrical bonding between the 

valve and the adjacent fitting. 

In the absence of proper electrical bonding 

within the motive flow system, the aeroplane 

fuel tank could be exposed to ignition 

sources in the case of a lightning strike. 

This [TCCA] directive is issued to [do a 

general visual inspection to] verify the proper 

configuration of the MFCV and if required, 

replace the affected MFCV with a MFCV that 

has a chemically filmed (gold color) outlet 

valve fitting, which provides adequate 

electrical bonding. 

The unsafe condition is the potential for 

ignition sources inside the fuel tanks, 

which, in combination with flammable 

fuel vapors, could result in a fuel tank 

explosion and consequent loss of the 

airplane. 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 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD affects about 67 

products of U.S. registry. We also 

estimate that it takes about 33 workhours 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 $130 per 

product. Based on these figures, we 

estimate the cost of the AD on U.S. 

operators to be $196,645, or $2,935 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

28640 Federal Register / Vol. 76, No. 96 / Wednesday, May 18, 2011 / Rules and Regulations 

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, 

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: 

2011–11–02 Bombardier, Inc.: Amendment 

39–16700. Docket No. FAA–2011–0043; 

Directorate Identifier 2010–NM–192–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective June 22, 2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Bombardier, Inc. 

Model DHC–8–400, -401, and -402 airplanes, 

certificated in any category; having serial 

numbers 4001 through 4190 inclusive, 4199 

through 4201 inclusive, and 4203 through 

4216 inclusive; equipped with a motive flow 

check valve (MFCV) having part number (P/ 

N) 2960018–101. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 28: Fuel. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

During production quality inspections of 

the aeroplane fuel motive flow system, it was 

discovered that some motive flow check 

valves (MFCV) were manufactured with an 

outlet fitting containing red anodized 

threads. These MFCV do not provide 

adequate electrical bonding between the 

valve and the adjacent fitting. 

In the absence of proper electrical bonding 

within the motive flow system, the aeroplane 

fuel tank could be exposed to ignition 

sources in the case of a lightning strike. 

* * * * * 

The unsafe condition is the potential for 

ignition sources inside the fuel tanks, which, 

in combination with flammable fuel vapors, 

could result in a fuel tank explosion and 

consequent loss 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 6,000 flight hours after the 

effective date of this AD, do a general visual 

inspection for red anodized threads of the 

outlet fitting of the MFCV having P/N

wing fuel tanks, in accordance with the 

Accomplishment Instructions of Bombardier 

Service Bulletin 84–28–08, dated March 11, 

2010. If the MFCV has a chemical film 

coating (gold color) outlet fitting, no further 

action is required by AD, except as required 

by paragraph (i) of this AD. 

(h) If during the inspection required by 

paragraph (g) of this AD, a MFCV having a 

red anodized check valve outlet fitting is 

found: Before further flight, replace the 

MFCV with a MFCV that has a chemical film 

coating (gold color) check valve outlet fitting, 

in accordance with the Accomplishment 

Instructions of Bombardier Service Bulletin 

84–28–08, dated March 11, 2010. 

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

person may install a replacement MFCV 

having P/N 2960018–101, with a red 

anodized check valve outlet fitting, on any 

airplane.
