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: 

During a recent production fuel system 

test, it was found that all three flapper valves 

located in each collector tank did not 

conform to the design requirements, due to 

the fact that a valve spring was installed on 

the flapper hinge pin. This valve spring 

should have been removed prior to 

installation of the valves. 

* * * * * 

With the valve spring installed, the flapper 

valve is held closed by the valve spring, 

preventing gravity feed. In the event of 

scavenge system failure, the collector tank 

fuel level can no longer be maintained, 

potentially leading to an in-flight engine 

shutdown. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

October 18, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 18, 2010.

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 April 26, 2010 (75 FR 

21530). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

During a recent production fuel system 

test, it was found that all three flapper valves 

located in each collector tank did not 

conform to the design requirements, due to 

the fact that a valve spring was installed on 

the flapper hinge pin. This valve spring 

should have been removed prior to 

installation of the valves. 

It was subsequently determined that this 

condition is restricted to the 21 aircraft listed 

in the Applicability section above. 

With the valve spring installed, the flapper 

valve is held closed by the valve spring, 

preventing gravity feed. In the event of 

scavenge system failure, the collector tank 

fuel level can no longer be maintained, 

potentially leading to an in-flight engine 

shutdown. 

In order to ensure adequate fuel transfer to 

the collector tank at all times, this directive 

mandates a one-time [detailed] inspection of 

each of the six flapper valves, removal of the 

valve spring, if installed, and application of 

an identification mark on each inspected 

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 

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. 

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 4 

products of U.S. registry. We also 

estimate that it will take about 30 workhours 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 $10,200, or $2,550 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,

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.

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: 

2010–19–02 Bombardier, Inc. Amendment 

39–16430. Docket No. FAA–2010–0432; 

Directorate Identifier 2010–NM–001–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective October 18, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Bombardier, Inc. 

Model DHC–8–201, –202, –301, –311, and 

–315 airplanes, certificated in any category, 

having serial numbers 644 through 664 

inclusive. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 28: Fuel. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

During a recent production fuel system 

test, it was found that all three flapper valves 

located in each collector tank did not 

conform to the design requirements, due to 

the fact that a valve spring was installed on 

the flapper hinge pin. This valve spring 

should have been removed prior to 

installation of the valves. 

It was subsequently determined that this 

condition is restricted to the 21 aircraft listed 

in the Applicability section above. 

With the valve spring installed, the flapper 

valve is held closed by the valve spring, 

preventing gravity feed. In the event of 

scavenge system failure, the collector tank 

fuel level can no longer be maintained, 

potentially leading to an in-flight engine 

shutdown. 

In order to ensure adequate fuel transfer to 

the collector tank at all times, this directive 

mandates a one-time [detailed] inspection of 

each of the six flapper valves, removal of the 

valve spring, if installed, and application of 

an identification mark on each inspected 

valve. 

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 1,000 flight hours after the 

effective date of this AD, do a detailed 

inspection of each collector tank flapper 

valve for the presence of a valve spring, in 

accordance with the Accomplishment 

Instructions of Bombardier Service Bulletin 

8–28–54, dated April 22, 2009. If the valve 

spring is not present, before further flight, 

apply an identification mark, in accordance 

with the Accomplishment Instructions of 

Bombardier Service Bulletin 8–28–54, dated 

April 22, 2009. If the valve spring is present, 

before further flight, remove the valve spring 

and apply an identification mark, in 

accordance with the Accomplishment 

Instructions of Bombardier Service Bulletin 

8–28–54, dated April 22, 2009.
