guarantees as provided in the general 

risk-based capital rules, that is, by 

substituting the risk weight appropriate 

to the guarantor or collateral for that of 

the exposure. This approach would 

have to be modified to exclude mention 

of external credit ratings for certain 

securities firms. The agencies could also 

incorporate into the recognition of 

collateral and guarantees some of the 

creditworthiness standards discussed 

above for sovereign, PSE, bank, and 

corporate exposures. 

Question 8: What are the advantages 

and disadvantages of the alternative 

approaches? What are the implications 

or potential for unintended 

consequences? Are there other 

approaches that would more 

appropriately capture the riskmitigating effects of collateral and/or 

guarantees without adding undue cost 

or burden? Commenters are asked to 

provide quantitative as well as 

qualitative supporting data and/or 

analysis for proposed alternative 

methods. 

d. Burden 

The agencies recognize that any 

measure of creditworthiness will 

involve a tradeoff among the objectives 

discussed in this ANPR. As previously 

noted, the agencies recognize that a 

more refined differentiation of 

creditworthiness may be achievable 

only at the expense of greater 

implementation burden. The agencies 

seek comment on the costs and burden 

that various alternative standards might 

entail. In particular, the agencies are 

interested in whether the development 

of alternatives to the use of credit 

ratings would involve, in most 

circumstances, cost considerations 

greater than those under the current 

regulations. 

Question 9: What burden might arise 

from the implementation of alternative 

methods of measuring creditworthiness 

at banking organizations of varying size 

and complexity? Commenters are asked 

to provide quantitative as well as 

qualitative support for their burden 

estimates. In addition to the cost 

burden, the agencies seek comment on 

the feasibility of implementing various 

alternatives, particularly for community 

and mid-sized banks.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: Several cases of aileron 

terminal quadrant support brackets that 

were manufactured using sheet metal 

have been found cracked on DHC–8 

Series 300 aircraft. Investigation 

revealed that the failure of the support 

bracket was due to fatigue. Failure of the 

aileron terminal quadrant support 

bracket could result in an adverse 

reduction of aircraft roll control. These 

conditions could result in loss of control 

of the airplane. The proposed AD would 

require actions that are intended to 

address the unsafe condition described 

in the MCAI. 

DATES: We must receive comments on 

this proposed AD by October 12, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2009–45, 

dated December 11, 2009 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Several cases of aileron terminal quadrant 

support brackets that were manufactured 

using sheet metal have been found cracked 

on DHC–8 Series 300 aircraft. Investigation 

revealed that the failure of the support 

bracket was due to fatigue. Failure of the 

aileron terminal quadrant support bracket 

could result in an adverse reduction of 

aircraft roll control. 

This directive mandates the replacement of 

the aileron terminal quadrant support bracket 

with a new and improved machined part. 

These conditions could result in loss 

of control of the airplane. The required 

actions include installing new aileron 

input quadrant support brackets. You 

may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Bombardier has issued Service 

Bulletin 8–57–43, Revision B, dated 

October 7, 2009. The actions described 

in this service information are intended 

to correct the unsafe condition 

identified in the MCAI. 

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. 

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 proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a Note within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 13 products of U.S. registry. 

We also estimate that it would take 

about 72 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $1,080 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 costs. 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 the 

proposed AD on U.S. operators to be 

$93,600, or $7,200 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 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); 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 proposed AD and placed it in the 

AD docket.

FAA AD Differences 

Note 1: This AD differs from the MCAI 

and/or service information as follows: No 

differences. 

Other FAA AD Provisions 

(i) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, New York Aircraft 

Certification Office (ACO), ANE–170, FAA, 

has the authority to approve AMOCs for this 

AD, if requested using the procedures found 

in 14 CFR 39.19. Send information to ATTN:

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Diamond Aircraft Industries GmbH 

Models DA 40 and DA 40F airplanes. 

This proposed AD would change the 

emergency open doors procedure by 

incorporation of a temporary revision 

into the FAA-approved airplane flight 

manual for all airplanes. This proposed 

AD would also require replacement of 

the passenger door retaining bracket 

with an improved design retaining 

bracket for certain airplanes. This 

proposed AD results from several 

reports of the rear passenger door 

departing the airplane in flight. We are 

proposing this AD to change the 

emergency open doors procedure and 

retrofit the rear passenger door retaining 

bracket, which if not corrected could 

result in the rear passenger door 

departing the airplane in flight. 

DATES: We must receive comments on 

this proposed AD by October 12, 2010. 

ADDRESSES: Use one of the following 

addresses to comment on this proposed 

AD:
