15870 Federal Register / Vol. 78, No. 49 / Wednesday, March 13, 2013 / Rules and Regulations 

2This provision applies only to the Banks and 

effectively precludes the termination of a Bank’s 

registration. 

Section 78oo(b)(1).2 As a result of SEC 

mandatory registration, each Bank is 

now required to make the periodic 

public disclosures made by similarly 

situated SEC registrants. Thus, the 

reason for the Finance Board regulation 

was superseded by Congressional 

action, and consequently the regulation 

is obsolete and warrants repeal and 

removal from the Code of Federal 

Regulations. Therefore, FHFA is hereby 

repealing part 998 in its entirety. 

D. Considerations of Differences 

Between the Banks and the Enterprises 

Section 1201 of HERA requires 

FHFA’s Director, when promulgating 

regulations ‘‘of general applicability and 

future effect’’ relating to the Banks, to 

consider the differences between the 

Banks and the Enterprises as they may 

relate to the Banks’ cooperative 

ownership structure, mission of 

providing liquidity to members, 

affordable housing and community 

development mission, capital structure, 

and joint and several liability. HERA 

section 1201, 122 Stat. 2782 (amending 

12 U.S.C. 4513). This final rule does not 

impose any new obligations on the 

Banks, but instead simply removes an 

existing Finance Board regulation that, 

as a result of the passage of HERA and 

changed circumstances, is obsolete, 

unnecessary and no longer of any 

regulatory purpose. The repeal of part 

998 of title 12 of the Code of Federal 

Regulations therefore would not have 

any ‘‘future effect’’ on the Banks. For 

these reasons, a section 1201 analysis is 

not required for this final rule. 

II. Notice and Public Participation 

FHFA finds that good cause exists 

under 5 U.S.C. 553(b)(B) of the 

Administrative Procedure Act for 

adopting these rule changes as a final 

rule without public notice and comment 

because the subject regulations 

currently have no regulatory purpose or 

value and thus their removal would be 

insignificant in nature and impact and 

of no consequence to the industry and 

the public. The provisions of part 1730 

were expressly intended to facilitate the 

Enterprises’ securities registration and 

associated financial disclosures, which 

had already been agreed to by the 

Enterprises. These requirements have 

subsequently been independently 

mandated under HERA. Similarly, the 

provisions of part 998 relate solely to 

the Finance Board’s requirement that 

the Banks register their equity securities 

under the 1934 Act and make attendant 

financial disclosures. These 

requirements too were subsequently 

mandated by the provisions of HERA. 

Neither of these regulations includes 

provisions that are appropriate for 

FHFA to carry over and incorporate into 

its own regulations, and thus they 

should be repealed and removed from 

the Code of Federal Regulations. For 

these reasons, FHFA believes that 

public comments are unnecessary and 

would serve no purpose. 

III. Paperwork Reduction Act 

The final rule does not contain any 

collections of information pursuant to 

the Paperwork Reduction Act of 1995 

(44 U.S.C. 3501 et seq.). Therefore, 

FHFA has not submitted any 

information to the Office of 

Management and Budget for review. 

IV. Regulatory Flexibility Act 

The final rule applies only to the 

Banks and Enterprises, which do not 

come within the meaning of small 

entities as defined in the Regulatory 

Flexibility Act (RFA). See 5 U.S.C. 

601(6). Therefore in accordance with 

section 605(b) of the RFA, FHFA 

certifies that this final rule will not have 

a significant economic impact on a 

substantial number of small entities.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2B19 

(Regional Jet Series 100 & 440) 

airplanes. This AD was prompted by 

reports that airplanes with a Class C 

cargo (baggage) compartment have liners 

that do not meet flammability 

requirements. This AD requires 

replacing the existing cargo 

compartment liners with liners that 

comply. We are issuing this AD to 

prevent inadequate fire protection in the 

cargo compartment and consequent 

uncontrolled fire. 

DATES: This AD becomes effective April 

17, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of April 17, 2013.

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 July 19, 2012 (77 FR 42457). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information (MCAI) 

states: 

It was found that the cargo compartment 

liners installed on CL–600–2B19 configured 

with Class C cargo compartment do not all 

meet the flammability requirements. Noncompliant cargo compartment liners may not 

provide adequate fire protection and could 

lead to an uncontrolled baggage bay fire. 

This [Canadian] AD mandates the 

replacement of existing cargo compartment 

liners with compliant cargo compartment 

liners.

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Change Applicability 

Air Wisconsin (AWI) requested that 

we change the applicability to either 

specify airplane serial numbers (S/Ns) 

7003 though 7067 inclusive, and S/Ns 

7069 through 7857 inclusive, including 

airplanes modified by STC ST01292NY, 

amended July 7, 2003 (http:// 

www.airweb.faa.gov/Regulatory_

and_Guidance_Library/rgstc.nsf/0/ 

1BB5140B1D3A130086256

D7A006DF851?OpenDocument

&Highlight=st01292ny); or specify the 

airplanes listed in Bombardier Service 

Bulletin 601R–25–187, Revision A, 

dated September 1, 2011; Bombardier 

Service Bulletin 601R–25–198, dated 

September 1, 2011; and Bombardier 

Service Bulletin 601R–25–199, dated 

September 1, 2011. AWI stated that the 

NPRM (77 FR 42457, July 19, 2012) 

specifies the applicability as airplane S/ 

Ns 7003 and subsequent, yet each of 

these Bombardier service bulletins 

describes the effectivity as airplane S/Ns 

7003 thru 7067 inclusive and S/Ns 7069 

thru 7857 inclusive, and states that the 

service bulletin was ‘‘validated’’ on 

airplane S/N 7362. 

We do not agree with the commenter’s 

request to change the applicability. The 

intent of this AD is to ensure that any 

Model CL–600–2B19 airplane 

configured with a Class C cargo 

compartment be equipped with 

compliant cargo compartment liners. 

The Bombardier service information 

referenced in paragraphs (g)(1) through 

(g)(3) of this AD has listed airplanes 

with known Class C cargo 

compartments. In order to ensure that 

any subsequently converted airplanes 

will be equally equipped with 

compliant Class C cargo compartment 

liners, this AD must apply to any Model 

CL–600–2B19 airplane configured with 

a Class C cargo compartment. We have 

not changed the AD in this regard. 

Requests To Extend Compliance Time 

AWI and Pinnacle Airlines (FLG) 

requested that we extend the 

compliance time from 28 months to 36 

months after the effective date of the 

AD. Both commenters stated that the 

service information recommends a 

compliance time of 36 months. 

Additionally, both commenters stated 

that the manufacturer has yet to supply 

the necessary parts kits. FLG noted that, 

without the parts kits, it could be put in 

a position of parking its airplanes. AWI 

stated that, without kits available, 

airplanes that are currently having their 

heavy check visits completed are 

without the benefit of the cargo 

compartment liner modification being 

accomplished. 

We do not agree with the commenters’ 

requests to extend the compliance time. 

In developing an appropriate 

compliance time for this action, we 

considered the safety implications, parts 

availability, and normal maintenance 

schedules for the timely 

accomplishment of the modification. 

Bombardier has confirmed with the 

FAA and Transport Canada Civil 

Aviation (TCCA) that parts are available 

to the operators, and the availability 

will be such that the operators will be 

able to incorporate the modification 

within the compliance time. However, 

under the provisions of paragraph (k) of 

this AD, we will consider requests for 

approval of an extension of the 

compliance time if sufficient data are 

submitted to substantiate that the new 

compliance time would provide an 

acceptable level of safety. We have not 

changed the AD in this regard. 

Request To Change Date of Parts 

Installation Prohibition or Remove 

Prohibition 

AWI requested that we either remove 

the paragraph or change the date of the 

prohibition of the installation of the old 

style liners (paragraph (i) of the NPRM 

(77 FR 42457, July 19, 2012)) from the 

effective date of the AD to 28 months 

after the effective date of the AD. AWI 

stated that in order to maintain a premodification airplane until the 

modification required by paragraph (g) 

of the NPRM is performed, the operator 

needs to have the flexibility to install 

the old style liners when replacing any 

that might become damaged. 

We agree to change the date of the 

prohibition of the installation of the old 

style liners for certain airplanes. We 

have changed paragraph (j)(1) of this AD 

(referred to as paragraph (i) of the NPRM 

(77 FR 42457, July 19, 2012)) to state 

that the installation of the old style 

liners for airplane S/Ns 7003 through 

7857 inclusive is prohibited after 

completion of the cargo compartment 

liner modification required by 

paragraph (g) of this AD, which is 

required within 28 months after the 

effective date of this AD. 

We have also added new paragraph 

(j)(2) to this AD, which states that the 

installation of the old style liners for 

airplane S/Ns 7858 and subsequent is 

prohibited as of the effective date of this 

AD. Airplane S/Ns 7858 and subsequent 

are/were not delivered with a class C 

cargo compartment. Paragraph (j)(2) of 

this AD prevents these airplanes from 

having the identified unsafe cargo liners 

installed if they are converted to class 

C cargo compartments. 

Request To Use Certain STC Parts 

AWI requested that we change the 

NPRM (77 FR 42457, July 19, 2012) to 

allow the installation of inserts, which 

are necessary for the installation of the 

rear wall liners in the floor panels 

specified in STC ST00560NY, amended 

June 29, 2001 (http://rgl.faa.gov/ 

Regulatory_and_Guidance_Library/ 

rgstc.nsf/0/78C85CD7FA9FAFA585256C

C2006A74D0?OpenDocument

&Highlight=st00560ny). AWI stated that 

Bombardier Service Bulletin 601R–25– 

187, Revision A, dated September 1, 

2011, does not mention these 

aftermarket panels and recognizes only 

the original equipment manufacturer 

floor panels. 

We agree with the commenter’s 

request. We have added new paragraph 

(h) to this AD, which states that Comtek 

Advanced Structures floor panels

equivalent to the original equipment 

floor panels described in Bombardier 

Service Bulletin 601R–25–187, Revision 

A, dated September 1, 2011, and may be 

used in lieu of the floor panels 

described in Bombardier Service 

Bulletin 601R–25–187, Revision A, 

dated September 1, 2011. We have reidentified subsequent paragraphs 

accordingly. 

Request To Approve Past or Future 

Repairs 

AWI requested that we make 

accommodation in the NPRM (77 FR 

42457, July 19, 2012) for previously 

approved or future approved repairs/ 

repair schemes without the need for 

alternative methods of compliance 

(AMOC) to do those repairs. AWI stated 

that the cargo compartment liners take 

quite a bit of abuse during loading/ 

unloading operations and are frequently 

in need of repair to maintain 

serviceability. AWI pointed out that 

there are existing approved repairs for 

the liners in the airplane maintenance 

manual and/or service repair manual. 

We disagree with the commenter’s 

request. This AD requires the 

installation of compliant cargo 

compartment liners. After 

accomplishing the actions required by 

this AD, maintenance and/or preventive 

maintenance under 14 CFR part 45 is 

permitted provided the maintenance 

does not result in changing the ADmandated configuration (reference 14 

CFR 39.7). We have not changed the AD 

in this regard. 

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– 

and minor editorial changes. We have 

determined that these changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

42457, July 19, 2012) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 42457, 

July 19, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

574 products of U.S. registry. We also 

estimate that it will take about 87 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 $43,559 

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 

$29,247,596, or $50,954 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 that 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); 

3. Will not affect intrastate aviation in 

Alaska; and 

4. 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

Airworthiness Directives; Airbus 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Airbus Model A300 B4–600, B4–600R, 

and F4–600R series airplanes, and 

Model A300 C4–605R Variant F 

airplanes (collectively called Model 

A300–600 series airplanes); and Model 

A310 series airplanes. This AD was 

prompted by a report of an 

uncommanded slide back of the co-pilot 

seat to the end stop position. This AD 

requires a one-time inspection for a part 

number, a tensile test of the affected 

seats, and corrective actions if 

necessary. We are issuing this AD to 

detect and prevent unwanted movement 

of a pilot or co-pilot seat in the 

horizontal direction, which could lead 

to inadvertent input on the flight control 

commands and possibly result in loss of 

controllability of the airplane. 

DATES: This AD becomes effective April 

17, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of April 17, 2013. 

ADDRESSES: You may examine the AD 

docket on the Internet at http://

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 10, 2012 (77 FR 

73343). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information (MCAI) 

states: 

During a steep climb manoeuvre that was 

flown with a high pitch (25°) for training of 

ground threat avoidance, an Airbus A310 

aeroplane experienced an uncommanded 

slide back of the co-pilot seat to the end stop 

position. 

Investigation revealed that on the affected 

seat, the disc key inside the clutch was 

broken. SOGERMA Service Bulletin (SB) No 

2510112–25–813, which addresses the 

previous end stop switch issue and which is 

covered by [European Aviation Safety 

Agency] EASA AD 2010–0070 [which 

corresponds to FAA AD 2011–06–09, 

Amendment 39–16634 (76 FR 15805, March 

22, 2011)] had been accomplished on this 

seat, but due to seizure, the key failure was 

not detected at time. This broken disc key 

caused a jamming between the gear and the 

shaft of the clutch. Despite this failure, the 

torque transmission between the gear and the 

shaft was sufficient for normal operation, but 

not to keep the seat in locked position during 

climbing, due to the high longitudinal loads 

generated by the high aeroplane incidence. 

This condition, if not detected and 

corrected, could cause the pilot to lose 

contact with the controls, leading to an 

inadvertent input on the flight control 

commands during take-off or climb, possibly 

resulting in loss of control of the aeroplane. 

For the reasons described above, this 

[EASA] AD requires a one-time inspection 

[part number (P/N) inspection of the seats 

and tensile test] of the affected seats and, 

depending on findings, accomplishment of 

applicable corrective action(s) [replacing the 

seat or modifying the seat by replacing 

actuator P/N RT19H4FX with a new 

actuator]. 

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 (77 

FR 73343, December 10, 2012), 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 except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

73343, December 10, 2012) for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 73343, 

December 10, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

161 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. 

Required parts will cost about $4,523 

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 

$741,888, or $4,608 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 that this AD:
