Powered Sailplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

the products listed above. This AD 

results from mandatory continuing 

airworthiness information (MCAI) 

issued 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: 

AD 2007–0315–E was issued to address a 

possible fuel leakage in the gear compartment 

in front of the engine and mandated 

inspections and replacement of fuel plasticmade connectors by connectors made of 

metal. Since its publication, another fuel 

leakage has been reported on a S10–VT 

which had implemented the STEMME 

Service Bulletin (SB) A31–10–082 as 

required by AD 2007–0315–E. 

It has been determined that the fuel leak 

may have been caused by the deformation 

that the originally installed clamps created 

on the fuel hoses and thus preventing the 

new clamps from being sufficiently pinched 

to perform a correct tightening. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective July 

6, 2010. 

On July 6, 2010, the Director of the 

Federal Register approved the 

incorporation by reference of STEMME 

F & D Service Bulletin A31–10–083, 

Am-Index: 01.b, dated May 6, 2009, 

listed in this AD. 

As of June 23, 2008 (73 FR 31355, 

June 2, 2008), the Director of the Federal 

Register approved the incorporation by 

reference of STEMME F & D Service 

Bulletin A31–10–083, Am-Index: 01.a, 

dated February 26, 2008, listed in this 

AD. 

As of February 20, 2008 (73 FR 5733,

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on July 3, 2008 (73 FR 38160), 

and proposed to supersede AD 2008– 

11–20, Amendment 39–15543 (73 FR 

31355, June 2, 2008). 

AD 2008–11–20 was issued as an 

interim action in order to address the 

need for the immediate prevention of 

leaks in the area of the fuel line. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, issued Emergency AD No. 

2008–0053–E, dated March 5, 2008 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. 

The EASA AD requires mandatory 

replacement of STEMME part number 

(P/N) M476 single-ear clamps in the fuel 

system with P/N 10M–181 single-ear 

clamps on all affected sailplanes within 

12 months after the effective date of the 

AD. 

The Administrative Procedure Act 

does not permit the FAA to ‘‘bootstrap’’ 

a long-term requirement into an urgent 

safety of flight action where the rule 

becomes effective at the same time the 

public has the opportunity to comment. 

The short-term action and the long-term 

action are analyzed separately for 

justification to bypass prior public 

notice. 

We are issuing this AD to address the 

mandatory replacement of all P/Ns 

M476 in the fuel system with P/Ns 

10M–181. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comment received. 

Comment Issue: Allow Installation of a 

Stainless Steel T- and Y-Connector in 

the Fuel System in Lieu of a Zinc Metal 

T- and Y-Connector 

Gary Rode requests allowance to 

install an appropriately sized stainless 

steel fuel connector fitting instead of the 

zinc metal connector specified in 

STEMME F & D Service Bulletin A31– 

10–083, Am-Index: 01.a, dated February 

26, 2008. 

Mr. Rode states the zinc metal fuel 

connector fitting identified in the 

manufacturer’s service bulletin is 

improperly sized and is made from a 

material that is susceptible to corrosion. 

Mr. Rode also states his disagreement 

with the manufacturer’s use of a smaller 

clamp to alleviate fuel leakage at the 

fuel connector/hose interface. 

Mr. Rode recommends using a 

specific stainless steel connector that 

has a larger outside diameter. He states 

that using a larger diameter connector 

would provide a better fit when 

matched with the fuel hose inside 

diameter, thereby eliminating fuel 

leakage. Also, using a stainless steel 

connector would provide greater 

corrosion resistance. 

We agree that the stainless steel 

connector is an acceptable replacement 

part. We do not agree that the zinc metal 

connector is an unsafe part. 

We have coordinated Mr. Rode’s 

concerns with the German airworthiness 

authority (LBA) and the manufacturer. 

The manufacturer has, in agreement 

with the LBA, revised STEMME F & D 

Service Bulletin A31–10–083, AmIndex: 01.a, dated February 26, 2008, to 

include allowance for installing a 

stainless steel connector as an optional 

replacement part. 

There has not been any safety issue 

related to the zinc metal connector 

reported in Europe or in the United 

States. Therefore, based on service 

history, we have elected at this time to 

not mandate a replacement of the zinc 

metal connector. 

We have changed the final rule AD 

action to incorporate using STEMME 

F & D Service Bulletin A31–10–083, 

Am-Index: 01.b, dated May 6, 2009, 

which allows installing a zinc metal fuel 

connector or a stainless steel fuel 

connector. 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of the 

AD.

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a NOTE within the AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD will affect 46 

products of U.S. registry. We also 

estimate that it will take about 3 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $80 per work-hour. 

Based on these figures, we estimate 

the cost of the AD on U.S. operators to 

be $11,040, or $240 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 AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

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 AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

(2) Is not a ‘‘significant rule’’ under 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

(3) 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD Docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 9 

a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains the NPRM, the 

regulatory evaluation, any comments 

received, and other information. The 

street address for the Docket Office 

(telephone (800) 647–5527) is in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt. 

List of Subjects in 14 CFR Part 39

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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 

removing Amendment 39–15543 (73 FR 

31355; June 2, 2008), and adding the 

following new AD: 

2010–11–08 Stemme GmbH & Co. KG: 

Amendment 39–16313; Docket No. 

FAA–2008–0788; Directorate Identifier 

2008–CE–039–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective July 6, 2010. 

Affected ADs 

(b) This AD supersedes AD 2008–11–20, 

Amendment 39–15543. 

Applicability 

(c) This AD applies to Model S10–VT 

powered sailplanes, serial numbers 11–001 

through 11–112, certificated in any category. 

Subject 

(d) Air Transport Association of America 

(ATA) Code 28: Fuel. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

AD 2007–0315–E was issued to address a 

possible fuel leakage in the gear compartment 

in front of the engine and mandated 

inspections and replacement of fuel plasticmade connectors by connectors made of 

metal. Since its publication, another fuel 

leakage has been reported on a S10–VT 

which had implemented the STEMME 

Service Bulletin (SB) A31–10–082 as 

required by AD 2007–0315–E. 

It has been determined that the fuel leak 

may have been caused by the deformation 

that the originally installed clamps created 

on the fuel hoses and thus preventing the 

new clamps from being sufficiently pinched 

to perform a correct tightening. 

The present Airworthiness Directive (AD) 

supersedes AD 2007–0315–E and requires 

you to check the fuel system according to the 

STEMME SB A31–10–083 as well as to 

replace single-ear clamps and plastic 

connectors. 

The actions specified by this AD are 

intended to reduce the potential for a fire to 

ignite and which could lead to loss of control 

of the sailplane. 

Actions and Compliance 

(f) Unless already done, do the following 

actions: 

(1) For all sailplanes affected by this AD, 

except for serial numbers 11–036, 11–067, 

11–068, and 11–090: Before further flight 

after March 21, 2008 (the compliance date 

retained from AD 2008–03–06, which was 

superseded by AD 2008–11–20), replace all

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Quartz Mountain Aerospace, Inc. Model 

11E airplanes. This AD requires you to 

clean and lubricate the aileron pushrod 

bearings. This AD results from reports of 

the aileron control stick force increasing 

and of the controls being very noisy. We 

are issuing this AD to detect and correct 

insufficient lubrication and residual 

metallic paint particles in the pushrod 

end ball joints, which could result in 

difficulty actuating aileron controls 

sometime during flight after takeoff. 

This condition could lead to difficulty 

controlling the airplane in flight. 

DATES: This AD becomes effective on 

July 6, 2010. 

On July 6, 2010, the Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD.
