Discussion 

European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2013– 

0123, dated June 5, 2013 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

ASK 21 sailplane spin characteristics can 

be controlled using tail ballast weights, 

ensuring that pilots of all weights can 

achieve the same spin results. Although the 

tail ballast weights were designed to control 

the centre of gravity of the sailplane, these 

weights significantly affect the inertia terms 

that govern the sailplane response to spin 

manoeuvres. Schleicher issued a Technical 

Note (TN) Nr. 4 in 1980 (mainly used in 

Switzerland) to provide instructions for the 

Aircraft Flight Manual (AFM) for spin 

training. These instructions did not provide 

proper protection against accomplishment of 

single seated flight with forgotten spin ballast 

installed. 

Schleicher issued a TN Nr. 4a in 2004 to 

provide instructions to the Aircraft Flight 

Manual (AFM) amendments to address spin 

ballast installation and facilitate two seated 

spin training. However, these instructions 

did not provide proper guidance for the spin 

entry techniques. The safety margin in 

respect to inertia limits was marginal for 

pilot weights less than 70 kg on the front 

seat. 

Furthermore, in one case, it was observed 

that a control surface gap was not sealed in 

accordance with design data approved for 

that aircraft. 

Single seated flight with forgotten spin 

ballast installed, if not corrected, could lead 

to sailplane operation beyond its centre of 

gravity limits. Flights with low inertia 

momentum around Y axis (as a result of the 

low weight crew) could result in reduced 

safety margin in respect to inertia limits. 

Improperly sealed control surface gap 

during spin recovery could lead to significant 

delay of recovery and reduced control of the 

sailplane. 

To address these potential unsafe 

conditions, Schleicher issued TN Nr. 4b for 

ASK 21 model sailplanes and TN Nr. 7 for 

ASK 21 Mi model sailplanes to amend the 

associated AFM and Aircraft Maintenance 

Manual (AMM) procedures and installation 

of a cockpit placard, as applicable to 

sailplane model. 


wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
2596 Federal Register / Vol. 79, No. 10 / Wednesday, January 15, 2014 / Proposed Rules 

For the reasons described above, this AD 

requires amendment of the AFM, AMM and 

installation of a cockpit placard. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov 

by searching for and locating it in 

Docket No. FAA–2014–0019. 

Relevant Service Information 

Alexander Schleicher GmbH & Co. 

Segelflugzeugbau issued ASK 21 

Technical Note Nr 4b, Issue for US 

registered gliders, dated October 31, 

2013. 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 59 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 $250 per 

product. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $27,287.50, or $462.50 

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.
