Airworthiness Directives; SchemppHirth Flugzeugbau GmbH Gliders 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for 

Schempp-Hirth Flugzeugbau GmbH 

Model Duo Discus T gliders. 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 the instructions 

provided to inspect the propeller hub 

and blades are insufficient for detecting 

cracks and/or other damage, and other 

operating instructions provided by the 

flight and maintenance manual are 

incorrect and insufficient. We are 

issuing this proposed AD to require 

actions to address the unsafe condition 

on these products. 

DATES: We must receive comments on 

this proposed AD by September 12, 

2013.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No.: 2013– 

0054, dated March 5, 2013 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

It was found that the accomplishment 

instructions provided to check the powered 

sailplane’s propeller hub and blades were not 

sufficient to detect cracks and/or other 

damage. The results of a subsequent manual 

review revealed that some other operating 

instructions provided by the sailplane flight 

and maintenance manual were neither 

correct nor sufficient. 

This condition, if not corrected, could lead 

to operation of the powered sailplane outside 

its certified limits. 

To address this unsafe condition, EASA 

issued AD 2013–0012 to require amendment 

of sailplane flight- and maintenance manuals 

to correct the operating instruction 

deficiencies and inaccuracies and, for Arcus 

T sailplanes that had been repaired before the 

applicable maintenance manual update, an 

elevator or wing flap hinge moment weight 

check, as applicable. 

Since that AD was published, SchemppHirth Flugzeugbau GmbH determined that 

Action 3 of the accomplishment instructions 

of Technical Note (Technische Mitteilung) 

(TN) 890–13, referenced for Duo Discus T 

sailplanes, was incorrect for S/N 1 through 

174. To correct this erroneous maintenance 

instruction, Schempp-Hirth Flugzeugbau 

GmbH issued TN 890–13 issue 2. 

For the reasons described above, this AD 

retains the requirements of EASA AD 2013– 

0012, which is superseded, and requires, for 

certain Duo Discus T powered sailplanes, the 

use of instructions as provided in TN 890– 

13 issue 2. 

The MCAI requires exchange of flight 

manual pages (which introduces a 

repetitive inspection of the power 

plant), exchange of maintenance manual 

pages, exchange of cockpit placards, and 

transfer of weight and balance data. 

EASA AD No.: 2013–0054 supersedes 

EASA AD No. 2013–0012, dated January 

15, 2013. No FAA action was taken on 

EASA AD No. 2013–0012. You may 

obtain further information by examining 

the MCAI in the AD docket. 


sroberts on DSK5SPTVN1PROD with PROPOSALS
45472 Federal Register / Vol. 78, No. 145 / Monday, July 29, 2013 / Proposed Rules 

Relevant Service Information 

Schempp-Hirth Flugzeugbau GmbH 

has issued Technical Note No. 890–13, 

2nd issue, dated March 5, 2013, for all 

the affected serial numbers; Duo Discus 

T Flight Manual TN 890–13, Revision 

12, dated November 2011, for serial 

numbers (S/N) 1 through 174; and Duo 

Discus T Flight Manual TN 890–13, 

Revision 2, dated November 2011, for 

S/N 175 through 240. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

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 5 products of U.S. registry. 

We also estimate that it would take 

about 2.5 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 $50 per product. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $1,312.50, or $262.50 per 

product. 

In addition, we estimate that any 

necessary follow-on actions (replace any 

parts found with cracks and repair any 

damage) would take about 5 work-hours 

and require parts costing $3,840, for a 

cost of $4,265 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. 

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
