Airworthiness Directives; Stemme 

GmbH & Co. KG Powered Sailplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Stemme GmbH & Co. KG Models S10, 

S10–V, and S10–VT powered sailplanes. 

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 unapproved 

rubber hoses installed in the engine 

fuel, oil, and cooling systems, which 

could lead to a system leak and result 

in an engine fire. We are issuing this AD 

to require actions to address the unsafe 

condition on these products. 

DATES: This AD is effective January 7, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of January 7, 2013.

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 September 18, 2012 (77 FR 

57531). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

An occurrence has been reported of an 

engine fire during ground run of a S10–VT 

powered sailplane. The investigation results 

indicated that an unapproved fuel hose was 

installed in the engine fuel system of that 

aeroplane. Subsequent survey of some Nregistered S 10 aeroplanes revealed more 

cases of installation of unapproved fuel, oil 

and cooling hoses on sailplanes engine 

systems. 

This condition, if not detected and 

corrected, could lead to a system leak with 

subsequent engine fire, possibly resulting in 

damage to the sailplane and/or injury of 

occupants. 

Prompted by these findings, Stemme 

GmbH developed a procedure for 

identification of these hoses, to have them 

removed from service. 

For the reasons described above, this AD 

requires a one-time review of the sailplane’s 

maintenance records to determine whether a 

serviceable engine hose kit for fuel, oil and 

cooling systems has been installed and, 

depending on findings, replacement of the 

affected hoses with serviceable parts. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (77 

FR 57531, September 18, 2012) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

57531, September 18, 2012) for 

correcting the unsafe condition; and 


emcdonald on DSK67QTVN1PROD with RULES
71488 Federal Register / Vol. 77, No. 232 / Monday, December 3, 2012 / Rules and Regulations 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 57531, 

September 18, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

63 products of U.S. registry. We also 

estimate that it will take about .5 workhour per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

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

be $2,677.50, or $42.50 per product. 

In addition, we estimate that any 

necessary follow-on actions will take 

about 8 work-hours and require parts 

costing $1,957, for a cost of $2,637 per 

product for Models S10 and S10–V. We 

also estimate that any necessary followon actions will take about 16 workhours and require parts costing $1,311, 

for a cost of $2,671 per product for 

Model S10–VT. 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 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 

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. 

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

safety, Incorporation by reference, 

Safety. 

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 adding 

the following new AD: 

2012–24–02 Stemme GmbH & Co. KG: 

Amendment 39–17272; Docket No. 

FAA–2012–0982; Directorate Identifier 

2012–CE–035–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective January 7, 2013. 

(b) Affected ADs 

None. 

(c) Applicability

powered sailplanes, all serial numbers, 

certificated in any category. 

(d) Subject 

Air Transport Association of America 

(ATA) Code 71: Powerplant. 

(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 

unapproved rubber hoses installed in the 

engine fuel, oil, and cooling systems. We are 

issuing this AD to prevent a system leak, 

which could lead to an engine fire. 

(f) Actions and Compliance 

Unless already done, do the following 

actions: 

(1) If, on January 7, 2013 (the effective date 

of this AD), the date of manufacture of the 

sailplane is less than five years old, before 

further flight after January 7, 2013 (the 

effective date of this AD), review the 

sailplane’s maintenance records/logbook for 

evidence as to whether the engine fuel, oil, 

and cooling systems rubber hoses have been 

replaced since new. Based on this review, if: 

(i) There is no maintenance records/ 

logbook evidence, i.e. logbook entry, that the 

engine fuel, oil, and cooling systems rubber 

hoses have been replaced since new, before 

further flight, make a logbook entry showing 

compliance with this AD. 

(ii) There is maintenance records/logbook 

evidence, i.e. logbook entry, that the engine 

fuel, oil, and/or cooling systems rubber hoses 

have been replaced since new, before further 

flight, review the sailplane’s maintenance 

records/logbook for current documentation of 

hose conformity through a Declaration of 

Conformity (DoC) or a European Aviation 

Safety Agency (EASA) Form 1. 

(A) If you can find current documentation 

of a DoC or an EASA Form 1, before further 

flight, make a logbook entry showing 

compliance with this AD. 

(B) If you cannot find current 

documentation of a DoC or an EASA Form 

1, before further flight, replace the affected 

hose(s) with FAA-approved serviceable hoses 

following Stemme F & D Installation 

Instruction A34–10–093–01, dated August 

13, 2012; or Stemme F & D Installation 

Instruction A34–10–093–02, dated August 

13, 2012, as applicable. 

(2) If, on January 7, 2013 (the effective date 

of this AD), the date of manufacture of the 

sailplane is five years old or older, before 

further flight after January 7, 2013 (the 

effective date of this AD), review the 

sailplane’s maintenance records/logbook for 

evidence of the date the engine fuel, oil, and 

cooling systems rubber hoses were last 

replaced and for documentation of hose 

conformity through a DoC or a EASA Form 

1. Based on this review, if: 

(i) There is maintenance records/logbook 

evidence, i.e. logbook entry, that the installed 

engine fuel, oil, and cooling systems rubber 

hoses are less than five years old and there 

is current documentation of hose conformity 

with a DoC or an EASA Form 1, before 

further flight, make a logbook entry showing 

compliance with this AD. 

(ii) There is maintenance records/logbook 

evidence, i.e. logbook entry, that the installed 

engine fuel, oil, and cooling systems rubber 

hoses are less than five years old, but there 

is no current documentation of hose 

conformity with a DoC or an EASA Form 1, 

before further flight, replace the affected 

hoses with FAA-approved serviceable hoses
