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: 

* * * The Federal Aviation Administration 

(FAA) has published Special Federal 

Aviation Regulation (SFAR) 88, and the Joint 

Aviation Authorities (JAA) have published 

Interim Policy INT/POL/25/12. The review, 

conducted by Fokker Services on the Fokker 

100 and Fokker 70 type design in response 

to these regulations, revealed that the fuel 

sense line from the overflow valves may 

touch the adjacent fuel-quantity indicationprobe. Under certain conditions, this may 

result in an ignition source in the wing tank 

vapour space. 

This condition, if not detected and 

corrected, could result in a wing fuel tank 

explosion and consequent loss of the 

aeroplane. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective July 

22, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of July 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 March 15, 2011 (76 FR 

13921). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

* * * The Federal Aviation Administration 

(FAA) has published Special Federal 

Aviation Regulation (SFAR) 88, and the Joint 

Aviation Authorities (JAA) have published 

Interim Policy INT/POL/25/12. The review, 

conducted by Fokker Services on the Fokker 

100 and Fokker 70 type design in response 

to these regulations, revealed that the fuel 

sense line from the overflow valves may 

touch the adjacent fuel-quantity indicationprobe. Under certain conditions, this may 

result in an ignition source in the wing tank 

vapour space. 

This condition, if not detected and 

corrected, could result in a wing fuel tank 

explosion and consequent loss of the 

aeroplane. 

For the reasons described above, this AD 

requires a one-time [general visual] 

inspection to check the route and clamping 

of the sense line hose and wiring conduit 

hose to each wing tank overflow valve and, 

depending on the findings, the necessary 

corrective actions. 

Corrective actions include installing two 

brackets next to the overflow valve on 

the main tank access panel, making a 

modification to the routing of the hose 

for the sense line, and installing clamps 

to keep the hoses in position. Required 

actions also include revising the 

maintenance program to include a 

Critical Design Configuration Control 

Limitation (CDCCL). 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 6 

products of U.S. registry. We also 

estimate that it will take about 2 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 $1,020, or $170 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 4 work-hours and require parts 

costing $800, for a cost of $1,140 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

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 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 76, No. 117 / Friday, June 17, 2011 / Rules and Regulations 35341 

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. 

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: 

2011–12–14 Fokker Services B.V.: 

Amendment 39–16721. Docket No. 

FAA–2011–0220; Directorate Identifier 

2010–NM–259–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective July 22, 2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to all Fokker Services 

B.V. Model F.28 Mark 0070 and 0100 

airplanes, certificated in any category. 

Note 1: This AD requires revisions to 

certain operator maintenance documents to 

include new actions (e.g., inspections) and/ 

or CDCCLs. Compliance with these actions 

and/or CDCCLs is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired in 

the areas addressed by this 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 (l) of this AD. The request 

should include a description of changes to 

the required actions that will ensure the 

continued operational safety of the airplane. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 28: Fuel. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

* * * The Federal Aviation Administration 

(FAA) has published Special Federal 

Aviation Regulation (SFAR) 88, and the Joint 

Aviation Authorities (JAA) have published 

Interim Policy INT/POL/25/12. The review, 

conducted by Fokker Services on the Fokker 

100 and Fokker 70 type design in response 

to these regulations, revealed that the fuel 

sense line from the overflow valves may 

touch the adjacent fuel-quantity indicationprobe. Under certain conditions, this may 

result in an ignition source in the wing tank 

vapour space. 

This condition, if not detected and 

corrected, 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. 

Actions 

(g) At a scheduled opening of the fuel tank, 

but not later than 84 months after the 

effective date of this AD, do a general visual 

inspection of the routing and clamping of the 

sense line hose and wiring conduit hose to 

each wing tank overflow valve, in accordance 

with Part 1 of the Accomplishment 

Instructions of Fokker Service Bulletin 

SBF100–28–050, Revision 1, dated July 28, 

2010. 

(h) If incorrect routing or clamping of the 

hoses is found during the inspection required 

by paragraph (g) of this AD, before further 

flight, install two brackets next to the 

overflow valve on the main tank access 

panel, make a modification to the routing of 

the hose for the sense line, and install clamps 

to keep the hoses in position, in accordance 

with Part 2 of the Accomplishment 

Instructions of Fokker Service Bulletin 

SBF100–28–050, Revision 1, dated July 28, 

2010. 

Critical Design Configuration Control 

Limitations (CDCCL) 

(i) Before further flight after determining 

that the routing and clamping of the sense 

line hose and wiring conduit hose to each 

wing tank overflow valve are correct, as 

required by paragraph (g) of this AD; or 

before further flight after doing the 

modification, as required by paragraph (h) of 

this AD; as applicable: Revise the aircraft 

maintenance program by incorporating the 

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

Service Bulletin SBF100–28–050, Revision 1, 

dated July 28, 2010. 

No Alternative Inspections, Inspection 

Intervals, or CDCCLs 

(j) After accomplishing the revision 

required by paragraph (i) of this AD, no 

alternative actions (e.g., inspections), 

intervals, and/or CDCCLs may be used unless 

the actions, intervals, and/or CDCCLs are 

approved as an alternative method of 

compliance (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 done before the effective date 

of this AD in accordance with Fokker Service 

Bulletin SBF100–28–050, dated June 3, 2010, 

are acceptable for compliance with the 

corresponding requirements of this AD. 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 

Although European Aviation Safety Agency 

(EASA) Airworthiness Directive 2010–0159, 

dated August 3, 2010, specifies revising the 

maintenance program to include limitations, 

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:

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 FAA-approved if they 

are approved by the State of Design Authority

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD requires 

a detailed inspection to detect distress 

and existing repairs to the leading edge 

structure of the vertical stabilizer at the 

splice at Station Zfs=52.267; repetitive 

inspections for cracking in the front spar 

cap forward flanges of the vertical 

stabilizer, and either the aft flanges or 

side skins; repetitive inspections for 

loose and missing fasteners; and related 

investigative and corrective actions if 

necessary. This AD was prompted by 

reports of cracked vertical stabilizer 

skin, a severed front spar cap, elongated 

fastener holes at the leading edge of the 

vertical stabilizer, and cracked front 

spar web and front spar cap bolt holes 

in the vertical stabilizer. We are issuing 

this AD to detect and correct such 

cracking damage, which could result in 

the structure being unable to support 

limit load, and could lead to the loss of 

the vertical stabilizer. 

DATES: This AD is effective July 22, 

2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of July 22, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to the 

specified products. That NPRM 

published in the Federal Register on 

March 14, 2011 (76 FR 13546). That 

NPRM proposed to require a detailed 

inspection to detect distress in, and 

existing repairs to, the leading edge 

structure of the vertical stabilizer at the 

splice at Station Zfs=52.267, and 

corrective action if necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

The Boeing Company supports the 

NPRM. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

We estimate that this AD affects 19 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD:
