another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as excessive load on the air 

brake system. We are issuing this 

proposed AD to require actions to 

address the unsafe condition on these 

products.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2015– 

0139R1, dated July 15, 2015 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

Operational experience shows that 

application of an excessive load on the air 

brake system may induce damage to the drive 

funnels in the fuselage and to the air brake 

bellcrank at the root rips of the wing. 

This condition, if not detected and 

corrected, could lead to an uncontrolled 

actuation of the air brakes (symmetric and 

asymmetric), possibly resulting in reduced 

control of the (powered) sailplane. 

To address this potential unsafe condition, 

Schempp-Hirth Flugzeugbau GmbH issued 

Technical Note (TN) 380–2, 396–17, 868–22 

and 890–14 (published as a single document) 

to provide inspection instructions. 

Consequently EASA issued AD 2015–0139 

to require to repetitive inspections of the air 

brake bellcrank, the air brake drive funnels 

and the airbrake control system, and 

replacement of damaged parts. 

Since that AD was issued, it was found that 

the drawing number of the reinforced air 

brake drive funnel was incorrectly stated in 

the original issue of the Schempp-Hirth TN. 

The wrongly referred drawing S14FB703 

refers to an existing part, different from air 

brake drive funnel and cannot be installed as 

a replacement part for air brake drive funnel. 

Consequently, Schempp-Hirth Flugzeugbau 

GmbH issued Revision 1 of TN 380–2, 396– 

17, 868–22 and 890–14, hearafter referenced 

to as ‘the revised TN’ in this AD. 

For the reasons described above, this AD 

is revised to require using the revised TN. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2015–3224.

Federal Register / Vol. 80, No. 149 / Tuesday, August 4, 2015 / Proposed Rules 46207 

procedures for inspecting and replacing 

the airbrake bell crank and the airbrake 

drive funnels and inspecting the 

airbrake control system for proper 

clearance and making necessary 

adjustments. This service information is 

reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section of this NPRM. 

FAA’s Determination and Requirements 

of the 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 this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 31 products of U.S. registry. 

We also estimate that it would take 

about 2 work-hours per product to 

comply with the basic inspection 

requirements of this proposed AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $5,270, or $170 per 

product. 

We estimate that it would take about 

4 work-hours per product to comply 

with the airbrake bell crank replacement 

requirement of this proposed AD. The 

average labor rate is $85 per work-hour. 

Required parts would cost about $500 

per product. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $26,040, or $840 per 

product. 

We estimate that it would take about 

4 work-hours per product to comply 

with the airbrake drive funnel 

replacement requirement of this 

proposed AD. The average labor rate is 

$85 per work-hour. Required parts 

would cost about $500 per product. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $26,040, or $840 per 

product 

In addition, we estimate that any 

necessary follow-on actions to make any 

necessary adjustments to the airbrake 

control system would take about 2 

work-hours for a cost of $170 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

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.

BILLING CODE 4910–13–P 

DEPARTMENT OF THE TREASURY 

31 CFR Part 23 

RIN 1505–AC51 

Nondiscrimination on the Basis of Age 

in Programs and Activities Receiving 

Federal Financial Assistance From the 

Department of the Treasury 

AGENCY: Department of the Treasury. 

ACTION: Proposed rule. 

SUMMARY: This proposed rule sets out 

the Department of the Treasury’s 

(Treasury) rules for implementing the 

Age Discrimination Act of 1975, as 

amended (the Act). The Act prohibits 

discrimination on the basis of age in 

programs and activities receiving federal 

financial assistance. The Act, which 

applies to persons of all ages, permits 

the use of certain age distinctions and 

factors other than age that meet the 

Act’s requirements. 

The Act and the related general, 

government-wide regulations require all 

agencies that extend federal financial 

assistance to issue agency-specific 

regulations implementing the Act. 

Treasury recipients have been subject to 

the Act and the government-wide 

regulations since their effective date in 

1979. Accordingly, today’s proposed 

rule does not substantially change 

Treasury recipients’ existing duty to 

refrain from discrimination on the basis 

of age. This proposal fulfills the 

obligation on Treasury to issue agencyspecific rules under the Act, clarifies the 

responsibilities of Treasury recipients 

under the Act, and describes the 

Treasury investigation, conciliation, and 

enforcement procedures to ensure 

compliance. 

DATES: Written comments must be 

received on or before October 5, 2015. 

ADDRESSES: Interested persons are 

invited to submit comments regarding 

this notice of proposed rulemaking 

according to the instructions below. All 

submissions must refer to the document 

title. The Department encourages the 

early submission of comments.
