Airworthiness Directives; CENTRAIR 

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 

CENTRAIR Models 101, 101A, 101AP, 

and 101P 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 structural damage to the 

fuselage. 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 March 3, 2014.

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– 

0258, dated October 25, 2013 (referred 

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

an unsafe condition for the specified 

products. The MCAI states: 

Occurrences of structural damage were 

reported on several Centrair 101 sailplane 

fuselage. The results of the subsequent 

investigations identified that these findings 

were accidental damage related and not 

identified in time during routine 

maintenance, due to inadequate maintenance 

instructions. 

This condition, if not detected and 

corrected, could reduce the structural 

integrity of the sailplane. 

To address this potential unsafe condition, 

Socie ́te ́ Nouvelle (SN) Centrair issued Service 

Bulletin (SB) 101–06 to provide instructions 

for structural inspections and Direction 

Ge ́ne ́rale de l’Aviation Civile (DGAC) of 

France issued AD 85–21–(A) to mandate the 

fuselage inspections described in that SB. 

Since that AD was issued, SN Centrair 

issued SB 101–06 at revision (rev.) 1 to 

provide improved instructions to identify 

accidental structural damages. 

For the reasons described above, this AD 

retains the requirements of DGAC France AD 

85–21–(A), which is superseded, but requires 

accomplishment of those fuselage structural 

inspections in accordance with improved 

instructions. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov 

by searching for and locating it in 

Docket No. FAA–2014–0018. 

Relevant Service Information 

Socie ́te ́ Nouvelle Centrair has issued 

Socie ́te ́ Nouvelle Centrair Mandatory 

Service Bulletin No. 101–06, Revision 1, 

dated August 5, 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 


wreier-aviles on DSK5TPTVN1PROD with PROPOSALS
2594 Federal Register / Vol. 79, No. 10 / Wednesday, January 15, 2014 / Proposed Rules 

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 43 products of U.S. registry. 

We also estimate that it would take 

about 3 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 $10,965, or $255 per 

product. 

Since there are currently no repair 

instructions available if discrepancies 

are found during the required proposed 

inspections, we have no way of 

determining the number of products 

that may need follow-on actions or what 

the cost per product would be. 

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.

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 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

CENTRAIR: Docket No. FAA–2014–0018; 

Directorate Identifier 2013–CE–049–AD. 

(a) Comments Due Date 

We must receive comments by March 3, 

2014. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to CENTRAIR Models 101, 

101A, 101P, and 101AP gliders, all serial 

numbers, certificated in any category. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 53: Fuselage. 

(e) Reason 

This AD was prompted by 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 structural 

damage to the fuselage. We are issuing this 

proposed AD to detect and correct structural 

damage not identified during routine 

maintenance inspections, which could lead 

to reduced structural integrity of the glider. 

(f) Actions and Compliance 

Unless already done, do the following 

actions in paragraphs (f)(1) through (f)(3) of 

this AD: 

(1) Within 25 days after the effective date 

of this AD and repetitively thereafter at 

intervals not to exceed every 12 months, 

inspect all fuselage frames and ribs following 

the instructions in Socie ́te ́ Nouvelle 

CENTRAIR Mandatory Service Bulletin 101– 

06, Revision 1, dated August 5, 2013. 

(2) If structural damage is detected during 

any inspection required by paragraph (f)(1) of 

this AD, before further flight, contact Socie ́te ́

Nouvelle CENTRAIR at the address specified 

in paragraph (h) of this AD to obtain FAAapproved repair instructions approved 

specifically for this AD, and before further 

flight, repair the glider using these repair 

instructions. 

(3) Accomplishment of a repair, as required 

by paragraph (f)(2) of this AD, does not 

constitute terminating action for the 

inspection required by paragraph (f)(1) of this 

AD. 

Note 1 to paragraph (f) of this AD: We 

recommend that you inspect the fuselage 

frames and ribs after the occurrence of any 

of the following events following the 

instructions in Socie ́te ́ Nouvelle CENTRAIR 

Mandatory Service Bulletin 101–06, Revision 

1, dated August 5, 2013: Landing with 

retracted gear, landing gear retraction during 

landing run, ground looping during take-off 

or landing, hard landing, or damage of 

internal structure of the fuselage. If structural 

damage is detected during any of these 

inspections, we recommend you contact 

Socie ́te ́ Nouvelle CENTRAIR at the address 

specified in paragraph (h) of this AD for 

approved repair instructions. 

(g) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Standards Office, 

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: Jim Rutherford, Aerospace Engineer, 

FAA, Small Airplane Directorate, 901 Locust, 

Room 301, Kansas City, Missouri 64106; 

telephone: (816) 329–4165; fax: (816) 329– 

4090; email: jim.rutherford@faa.gov. Before 

using any approved AMOC on any airplane 

to which the AMOC applies, notify your 

appropriate principal inspector (PI) in the 

FAA Flight Standards District Office (FSDO), 

or lacking a PI, your local FSDO. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, a federal 

agency may not conduct or sponsor, and a 

person is not required to respond to, nor 

shall a person be subject to a penalty for 

failure to comply with a collection of 

information subject to the requirements of 

the Paperwork Reduction Act unless that 

collection of information displays a current 

valid OMB Control Number. The OMB 

Control Number for this information 

collection is 2120–0056. Public reporting for 

this collection of information is estimated to 

be approximately 5 minutes per response, 

including the time for reviewing instructions, 

completing and reviewing the collection of 

information. All responses to this collection 

of information are mandatory. Comments 

concerning the accuracy of this burden and 

suggestions for reducing the burden should

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.
