Airworthiness Directives; Sicma Aero 

Seat Passenger Seat Assemblies, 

Installed on, But Not Limited to, ATR– 

GIE Avions de Transport Re ́gional 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

certain Sicma Aero Seat Model 9401, 

9402, 9404, 9505, 9406, 9407, 9408, and 

9409 series passenger seat assemblies, 

installed on, but not limited to, ATR— 

GIE Avions de Transport Re ́gional 

Model ATR42 and ATR72 airplanes. 

That AD currently requires repetitive 

detailed inspections for cracking of the 

central and lateral spreaders of the 

affected seats, and repair or replacement 

of the spreader if necessary. This AD 

was prompted by a determination that 

the existing AD included Model 9505 

series passenger seat assemblies in the 

applicability instead of Model 9405 

series passenger seat assemblies. We are 

issuing this AD to detect and correct 

cracking of the central and lateral 

spreaders, which could lead to further 

cracking of the seat spreaders, causing 

injury to passengers or crew members 

during heavy turbulence in flight or in 

the event of an emergency landing. 

DATES: This AD becomes effective May 

9, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of November 21, 2011 (76 FR 68304, 

November 4, 2011). 

We must receive comments on this 

AD by June 8, 2012.

SUPPLEMENTARY INFORMATION: On 

October 20, 2011, we issued AD 2011– 

23–06, Amendment 39–16857 (76 FR 

68304, November 4, 2011). That AD 

required actions intended to address an 

unsafe condition on Sicma Aero Seat 

Model 9401, 9402, 9404, 9505, 9406, 

9407, 9408, and 9409 series passenger 

seat assemblies, installed on, but not 

limited to, ATR—GIE Avions de 

Transport Re ́gional Model ATR42 and 

ATR72 airplanes. 

Since we issued AD 2011–23–06, 

Amendment 39–16857 (76 FR 68304, 

November 4, 2011), we have determined 

that the applicability of that AD 

included Model 9505 series passenger 

seat assemblies in the applicability 

instead of Model 9405 series passenger 

seat assemblies. We have revised the 

applicability of this AD accordingly and 

added new paragraph (h) for Sicma Aero 

Seat Model 9405 series passenger seat 

assemblies. 

Change to Existing AD 

Since we issued AD 2011–23–06, 

Amendment 39–16857 (76 FR 68304, 

November 4, 2011), the AD format has 

been revised, and certain paragraphs 

have been rearranged. As a result, the 

corresponding paragraph identifiers 

have changed in this AD, as listed in the 

following table:

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are issuing this 

AD because we evaluated all pertinent 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

There are no products of this type 

currently registered in the United States. 

However, this rule is necessary to 

ensure that the described unsafe 

condition is addressed if any of these 

products are placed on the U.S. Register 

in the future. 

FAA’s Determination of the Effective 

Date 

Since there are currently no domestic 

operators of this product, notice and 

opportunity for public comment before 

issuing this AD are unnecessary. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2012–0334; 

Directorate Identifier 2012–NM–001– 

AD’’ at the beginning of your comments. 

We specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 77, No. 79 / Tuesday, April 24, 2012 / Rules and Regulations 24361 

amend this AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD. 

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. 

List of Subjects in 14 CFR Part 39

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

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 of the air driven generator (ADG) 

failing to power essential buses during 

functional tests, due to the low 

threshold setting of the circuit 

protection on the ADG’s generator 

control unit (GCU) preventing the ADG 

from supplying power to the essential 

buses. This AD requires installing a new 

or serviceable ADG GCU. We are issuing 

this AD to prevent loss of power from 

the ADG to the essential buses which, 

in the event of an emergency, could 

prevent continued safe flight. 

DATES: This AD becomes effective May 

29, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of May 29, 2012.
