provide NCUA with any relevant 

qualitative or quantitative information 

requested by NCUA pertinent to the 

stress tests under this section. 

(f) Stress test results. NCUA will 

provide each covered credit union with 

the results of the stress tests by July 31 

of the year in which it conducted the 

tests. A credit union conducting its own 

stress tests must incorporate the test 

results in its capital plan. 

(g) Supervisory actions. If NCUA-run 

stress tests show that a covered credit 

union does not have the ability to 

maintain a stress test capital ratio of 5 

percent or more under expected and 

stressed conditions in each quarter of 

the 9-quarter horizon, the credit union 

must provide NCUA, by October 31 of 

the calendar year in which NCUA 

conducted the tests, a stress test capital 

enhancement plan showing how it will 

meet that target. If credit union-run 

stress tests show that a covered credit 

union does not have the ability to 

maintain a stress test capital ratio of 5 

percent or more under expected and 

stressed conditions in each quarter of 

the 9-quarter horizon, the credit union 

must incorporate a stress test capital 

enhancement plan into its capital plan. 

Any affected credit union operating 

without a stress test capital 

enhancement plan accepted by NCUA 

may be subject to supervisory actions on 

the part of NCUA.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

ATR—GIE Avions de Transport 

Re ́gional Model ATR42 airplanes. This 

proposed AD was prompted by several 

reports of a cracked floor beam at frame 

(FR) 26, and of discrepancies in certain 

wing inspection tasks in maintenance 

documents that could lead to errors in 

scheduling inspection intervals of 

structurally significant items (SSIs). 

This proposed AD would require 

repetitive inspections of certain floor 

beams and revision of the maintenance 

or inspection program to include 

inspections of several areas of the 

wings. We are proposing this AD to 

detect and correct any cracking of the 

floor beam at FR 26 and several areas of 

the wings, which could lead to reduced 

structural integrity of the airplane. 

DATES: We must receive comments on 

this proposed AD by March 12, 2015.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2012–0193, dated September 

25, 2012 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for all ATR—GIE 

Avions de Transport Re ́gional Model 

ATR42 airplanes. The MCAI states: 

Floor beam at Frame 26: During 

maintenance checks, the floor beam at frame 

(FR) 26 was found cracked on several ATR 

42 aeroplanes. 

This condition, if not detected and 

corrected, could lead to reduce the structural 

integrity of the aeroplane. A new Structural 

Significant Items (SSI) task will be 

introduced in the next revision of the ATR42 

Time Limits document in order to address 

this issue. 

MRBR/MPD discrepancy on Wings item: A 

discrepancy has been noticed between the 

Maintenance Review Board Report (MRBR)/ 

Maintenance Planning Document (MPD) and 

the Time Limits document. ATR 

modifications 02805 and 08039 were 

erroneously stated similar in the MRBR/

MPD, inducing misleading applicability of 

the SSI tasks depending upon the document 

used and leading operators to miss several 

inspections, as evidenced during a recent 

review. 

Following the structural investigation, new 

inspection thresholds have been calculated 

and will be introduced in the next revisions 

of the ATR Time Limits documents (Revision 

8 and Revision 9, as applicable to the 

aeroplane models) and MRBR/MPD 

documents. 


tkelley on DSK3SPTVN1PROD with PROPOSALS
3922 Federal Register / Vol. 80, No. 16 / Monday, January 26, 2015 / Proposed Rules 

For the reasons described above, this 

[EASA] AD requires repetitive inspections of 

the FR26 floor beam, and of several areas of 

the wings, as defined in the ATR42 Time 

Limits document and, depending on 

findings, the accomplishment of applicable 

corrective action(s). 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

0080. 

Related Service Information 

Avions de Transport Re ́gional (ATR) 

has issued Job Instruction Card 535100 

DVI 10097, ‘‘DVI of FR26 Floor Beam 

Around Cut-outs for Cooling & Hydrau 

Ducts,’’ dated February 9, 2012 (for 

Model ATR42–200, –300, –320, and 

–500 airplanes). The service information 

describes procedures for a detailed 

inspection for damage (cracks, 

corrosion, dents, scratches, scores and 

abrasions) of the floor beam at FR 26, on 

the left-hand (LH) and right-hand (RH) 

sides, and, for certain inspection 

findings, contacting the manufacturer 

for repair instructions. 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. 

Difference Between This Proposed AD 

and the MCAI 

Although the MCAI specifies doing 

repetitive actions (e.g., structurally 

significant item (SSI) inspections) in 

accordance with certain tasks in the 

maintenance or inspection program, this 

NPRM proposes to revise the 

maintenance or inspection program, as 

applicable, in accordance with a method 

approved by the Manager, International 

Branch, ANM–116, Transport Airplane 

Directorate, FAA. By requiring a 

revision of the maintenance or 

inspection program, as applicable, 

instead of requiring individual 

repetitive inspections, operators are 

only required to record AD compliance 

once when the maintenance or 

inspection program is revised instead of 

every time an inspection is 

accomplished. The repetitive 

inspections specified in the 

airworthiness limitations must be 

complied with in accordance with 14 

CFR 91.403(c). 

Also, the MCAI specifies that, if there 

are findings from the inspections, then 

corrective action must be accomplished 

in accordance with ATR maintenance 

documentation. But this proposed AD 

does not include that requirement 

because operators of U.S.-registered 

airplanes are required by general 

airworthiness and operational 

regulations to use FAA-acceptable 

methods when performing maintenance. 

We consider those methods to be 

adequate to address any corrective 

action necessitated by the findings of 

airworthiness limitations section (ALS) 

inspections specified in the 

maintenance or inspection program 

revision required by this proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 31 airplanes of U.S. registry. 

We estimate that it would take about 

4 work-hours per product to comply 

with the basic requirements of this 

proposed AD. The average labor rate is 

$85 per work-hour. Based on these 

figures, we estimate the cost of this 

proposed AD on U.S. operators to be 

$10,540, per inspection cycle, or $340, 

per inspection cycle, 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); 

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.

would require modifying the aft 

equipment bay. We are proposing this 

AD to prevent excessive quantities of 

flammable fluid accumulation in the aft 

equipment bay. Flammable fluid entry 

and accumulation in the aft equipment 

bay, in excessive quantities, could 

exceed safe levels maintained by the 

drainage and ventilation system.

Discussion 

Transport Canada Civil Aviation, 

which is the aviation authority for 

Canada, has issued Canadian 

Airworthiness Directive CF–2014–25, 

dated August 7, 2014 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model BD– 

700–1A10 and BD–700–1A11 airplanes. 

The MCAI states: 

There have been two reports of fluid entry 

and accumulation in the aft equipment bay. 

The leaked fluid in the first incident was fuel 

and the fluid in the second incident was test 

dye. Further investigation revealed that 

leaked fluid from the aft fuel tank drain 

entered the bay through the slot in the door 

latch mechanism. 

Flammable fluid entry and accumulation 

in the aft equipment bay, in excessive 

quantities, could exceed safe levels 

maintained by the drainage and ventilation 

system. 

Bombardier Inc. has issued several Service 

Bulletins (SB) to modify the Aft Equipment 

Bay by installing a cover to the door latch 

mechanism in order to reduce the risk of fuel 

entry into it. This [Canadian] AD mandates 

the incorporation of the applicable 

Bombardier Inc. SBs to rectify this problem. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

0081.

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.
