United States Standards for Wheat 

AGENCY: Grain Inspection, Packers and 

Stockyards Administration, USDA. 

ACTION: Proposed rule; corrections. 

SUMMARY: This document corrects the 

preamble and the regulatory text to a 

proposed rule published by the Grain 

Inspection, Packers and Stockyards 

Administration (GIPSA) in the Federal 

Register of April 11, 2012, regarding a 

proposal to revise the U.S. Standards for 

Wheat under the U.S. Grain Standards 

Act. The proposed rule would change 

the definition of Contrasting classes in 

Hard White wheat and change the grade 

limits for shrunken and broken kernels. 

GIPSA believes that these proposed 

changes will help to facilitate the 

marketing of wheat. 

DATES: The comment period closing 

date for the proposed rule published 

April 11, 2012, at 77 FR 21685 remains 

June 11, 2012.

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to certain Bombardier, Inc. 

Model CL–600–2B19 (Regional Jet 

Series 100 & 440) airplanes. The existing 

AD currently requires revising certain 

sections of a certain airplane flight 

manual, deactivating certain hydraulic 

accumulators, removing certain 

hydraulic accumulators, ultrasonic 

inspections for cracks on accumulators 

and screw caps and replacement if 

necessary, and replacing certain 

accumulators. Since we issued that AD, 

we have determined that, for certain 

airplanes, reducing the compliance time 

for a certain replacement is necessary to 

ensure that the identified unsafe 

condition is addressed. This proposed 

AD would continue to require the 

existing actions from the existing AD. 

We are proposing this AD to detect and 

correct hydraulic accumulator screw 

cap/end cap failure, which could result 

in the loss of the associated hydraulic 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 77, No. 76 / Thursday, April 19, 2012 / Proposed Rules 23421 

system and high-energy impact damage 

to adjacent systems and structure, and 

consequent loss of control of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by June 4, 2012.

proposed AD based on those comments. 

We will post all comments we

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

On October 20, 2011, we issued AD 

2011–23–08, Amendment 39–16859 (76 

FR 71241, November 17, 2011). That AD 

required actions intended to address an 

unsafe condition on certain Bombardier, 

Inc. Model CL–600–2B19 (Regional Jet 

Series 100 & 440) Airplanes. 

Since we issued AD 2011–23–08, 

Amendment 39–16859 (76 FR 71241, 

November 17, 2011), we have 

determined that the compliance time 

specified in paragraph (n) of this 

proposed AD (referred to as paragraph 

(q) in AD 2011–23–08) must be clarified. 

We are including the phrase, 

‘‘whichever occurs first,’’ in paragraph 

(n)(1) of this AD, which requires 

operators to perform the action at the 

earlier of the times. We have determined 

that the proposed reduced compliance 

time is necessary to address the 

identified unsafe condition in a timely 

manner. This compliance time also 

matches the compliance time given in 

Canadian Airworthiness Directive CF– 

2010–24, dated August 3, 2010. 

We have also determined that certain 

phrases need to be added and certain 

phrases need to be removed from certain 

credit paragraphs of this AD. We have 

revised paragraphs (o)(4) and (o)(5) of 

this proposed AD to specify ‘‘before 

December 22, 2011 (the effective date of 

AD 2011–23–08, Amendment 39–16859 

(76 FR 71241, November 17, 2011)),’’ 

instead of ‘‘before November 4, 2010.’’ 

We have revised paragraph (o)(2) of this 

AD by removing ‘‘hydraulic system No. 

1’’ because the service information in 

paragraph (o)(2) does not specify to 

remove the hydraulic system No. 1 

accumulator. We have also revised 

paragraph (o)(2) of this proposed AD by 

removing Bombardier Service Bulletin 

601R–32–107, Revision A, dated June 

17, 2010, because credit for that service 

bulletin is already given in paragraph 

(m) of this proposed AD. You may 

obtain further information by examining 

the MCAI in the AD docket. 

FAA’s Determination and Requirements 

of This Proposed 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 proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Changes to Existing AD 

This proposed AD would retain all 

requirements of AD 2011–23–08, 

Amendment 39–16859 (76 FR 71241, 

November 17, 2011). Since AD 2011– 

23–08 was issued, the AD format has 

been revised, and certain paragraphs 

have been rearranged. As a result, the 

corresponding paragraph identifiers 

have changed in this proposed AD, as 

listed in the following table: 

REVISED PARAGRAPH IDENTIFIERS

paragraph (o) paragraph (l) 

paragraph (p) paragraph (m) 

paragraph (q) paragraph (n) 

paragraph (r) paragraph (o)(4) 

paragraph (s) paragraph (o)(5) 

We have also revised paragraph (j) 

(paragraph (j) of AD 2011–23–08, 

Amendment 39–16859 (76 FR 71241, 

November 17, 2011)) of this proposed 

AD to refer to paragraph (k) of this AD 

instead of paragraph (l)(1) (paragraph (l) 

of AD 2011–23–08) for the applicable 

compliance times. 

Differences Between This AD and the 

MCAI or Service Information 

The actions specified in Canadian 

Airworthiness Directive CF–2010–24, 

dated August 3, 2010, apply only to 

Tactair accumulators. The actions 

required by paragraphs (h), (i), and (m) 

of this proposed AD apply to all 

accumulators in the positions specified 

in paragraphs (h), (i), and (l) of this 

proposed AD. 

While Canadian Airworthiness 

Directive CF–2010–24, dated August 3, 

2010, does not require replacement of 

the reducer of the hydraulic system No.

23422 Federal Register / Vol. 77, No. 76 / Thursday, April 19, 2012 / Proposed Rules 

1 with a new reducer, paragraph (n) of 

this proposed AD does. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 605 products of U.S. 

registry. 

The actions that are required by AD 

2011–23–08, Amendment 39–16859 (76 

FR 71241, November 17, 2011), and 

retained in this proposed AD take about 

33 work-hours per product, at an 

average labor rate of $85 per work hour. 

Required parts cost about $3,054 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, the estimated cost of the 

currently required actions is $5,859 per 

product. 

The new requirements of this 

proposed AD add no additional 

economic burden. 

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 proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 proposed regulation: 

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 proposed AD and placed it in the 

AD docket. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 

removing airworthiness directive (AD) 

2011–23–08, Amendment 39–16859 (76 

FR 71241, November 17, 2011), and 

adding the following new AD:
