Background The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018–0127, PO 00000 Frm 00030 Fmt 4702 Sfmt 4702 dated June 11, 2018 (referred to after this as ‘‘the MCAI’’), to address an unsafe condition on DG Flugzeugbau GmbH Models DG–808C and DG–1000T gliders. The MCAI states: An occurrence was reported where, during accomplishment of a 10 years inspection on a DG–808C powered sailplane, a damaged (broken) PU [polyurethane] fuel hose was found. The result of subsequent investigation indicated that the damage mode has features of environmental and fatigue deterioration. Additionally, it was determined that similar PU fuel hoses are also installed on other powered sailplane types of the same manufacturer. This condition, if not detected and corrected, could lead to reduced or interrupted fuel supply to the engine, consequent loss of the available power or fire, possibly resulting in reduced control of the powered sailplane. To address this potential unsafe condition, DG-Flugzeugbau GmbH issued the applicable TN [Technical Note], providing instructions to inspect the affected parts and replace these with serviceable parts. Additionally, service life limits were established for those serviceable parts. For the reasons described above, this [EASA] AD requires repetitive inspections of the affected parts. This [EASA] AD also requires replacement of the affected parts with serviceable parts and introduces life limits for serviceable parts. You may examine the MCAI in the AD docket at https:// www.regulations.gov by searching for and locating Docket No. FAA–2021– 0212. Related Service Information Under 1 CFR Part 51 The FAA reviewed DG Flugzeugbau GmbH Technical Note No. 800/46, Issue 01.a, dated March 7, 2018, for Model DG–808C gliders; and Technical Note No. 1000/38, Issue 01.a, dated February 15, 2018, for Model DG–1000T gliders. The service information, as applicable to the appropriate model glider, specifies inspections of the PU fuel hoses, replacement of the PU fuel hoses if damage is found during an inspection, and actions to take when the hoses have reached their life limit. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in ADDRESSES. FAA’s Determination 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, it has notified the FAA of the unsafe condition described in the MCAI and service information E:\FR\FM\01JYP1.SGM 01JYP1 Federal Register / Vol. 86, No. 124 / Thursday, July 1, 2021 / Proposed Rules referenced above. The FAA is issuing this NPRM after determining the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in the service information already described, except as discussed under ‘‘Differences Between this Proposed AD and the MCAI.’’ Differences Between This Proposed AD and the MCAI The MCAI requires replacing any damaged fuel hoses before next engine operation, while this proposed AD would require replacing damaged fuel hoses before further flight. Even though use of the engine is optional and the glider can operate without the engine, the glider has other electronic equipment installed that could cause arcing and result in an in-flight fire if there is a fuel leak. khammond on DSKJM1Z7X2PROD with PROPOSALS Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 10 gliders of U.S. registry. The FAA also estimates that it would take about 2 work-hours per glider to comply with each inspection required by this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, the FAA estimates the inspection cost of this proposed AD on U.S. operators to be $1,700, or $170 per glider, each inspection cycle. In addition, the FAA estimates that each replacement action required by this proposed AD would take about 8 work-hours and require parts costing $500. Based on these figures, the FAA estimates the replacement cost of this proposed AD on U.S. operators to be $1,180 per glider. 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. The FAA is 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 VerDate Sep<11>2014 16:17 Jun 30, 2021 Jkt 253001 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 The FAA 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) Would not affect intrastate aviation in Alaska, and (3) Would 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 1.

Airworthiness Directives; DG Flugzeugbau GmbH Gliders

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all

[[Page 35028]]

DG Flugzeugbau GmbH Models DG-808C and DG-1000T gliders. This proposed 
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 damaged fuel hoses due to 
environmental and fatigue deterioration. This proposed AD would require 
inspecting the polyurethane (PU) fuel hoses, replacing the PU fuel 
hoses if there is damage, and establishing a life limit for the PU fuel 
hoses. The FAA is proposing this AD to address the unsafe condition on 
these products.

DATES: The FAA must receive comments on this proposed AD by August 16, 
2021.

Background

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0127, dated June 11, 2018 (referred to after this as ``the 
MCAI''), to address an unsafe condition on DG Flugzeugbau GmbH Models 
DG-808C and DG-1000T gliders. The MCAI states:

    An occurrence was reported where, during accomplishment of a 10 
years inspection on a DG-808C powered sailplane, a damaged (broken) 
PU [polyurethane] fuel hose was found. The result of subsequent 
investigation indicated that the damage mode has features of 
environmental and fatigue deterioration. Additionally, it was 
determined that similar PU fuel hoses are also installed on other 
powered sailplane types of the same manufacturer.
    This condition, if not detected and corrected, could lead to 
reduced or interrupted fuel supply to the engine, consequent loss of 
the available power or fire, possibly resulting in reduced control 
of the powered sailplane.
    To address this potential unsafe condition, DG-Flugzeugbau GmbH 
issued the applicable TN [Technical Note], providing instructions to 
inspect the affected parts and replace these with serviceable parts. 
Additionally, service life limits were established for those 
serviceable parts.
    For the reasons described above, this [EASA] AD requires 
repetitive inspections of the affected parts. This [EASA] AD also 
requires replacement of the affected parts with serviceable parts 
and introduces life limits for serviceable parts.

    You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0212.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed DG Flugzeugbau GmbH Technical Note No. 800/46, 
Issue 01.a, dated March 7, 2018, for Model DG-808C gliders; and 
Technical Note No. 1000/38, Issue 01.a, dated February 15, 2018, for 
Model DG-1000T gliders. The service information, as applicable to the 
appropriate model glider, specifies inspections of the PU fuel hoses, 
replacement of the PU fuel hoses if damage is found during an 
inspection, and actions to take when the hoses have reached their life 
limit. This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in ADDRESSES.

FAA's Determination

    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, it has 
notified the FAA of the unsafe condition described in the MCAI and 
service information

[[Page 35029]]

referenced above. The FAA is issuing this NPRM after determining the 
unsafe condition described previously is likely to exist or develop on 
other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information already described, except as discussed under 
``Differences Between this Proposed AD and the MCAI.''

Differences Between This Proposed AD and the MCAI

    The MCAI requires replacing any damaged fuel hoses before next 
engine operation, while this proposed AD would require replacing 
damaged fuel hoses before further flight. Even though use of the engine 
is optional and the glider can operate without the engine, the glider 
has other electronic equipment installed that could cause arcing and 
result in an in-flight fire if there is a fuel leak.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 10 gliders of U.S. registry. The FAA also estimates that it 
would take about 2 work-hours per glider to comply with each inspection 
required by this proposed AD. The average labor rate is $85 per work-
hour.
    Based on these figures, the FAA estimates the inspection cost of 
this proposed AD on U.S. operators to be $1,700, or $170 per glider, 
each inspection cycle.
    In addition, the FAA estimates that each replacement action 
required by this proposed AD would take about 8 work-hours and require 
parts costing $500. Based on these figures, the FAA estimates the 
replacement cost of this proposed AD on U.S. operators to be $1,180 per 
glider.

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.
    The FAA is 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

    The FAA 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) Would not affect intrastate aviation in Alaska, and
    (3) Would 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:

    (1) Before or upon accumulating 6 years since first installation 
on a glider and thereafter at intervals not to exceed 12 months, 
visually inspect each serviceable part for fissures, kinks, and 
leaks. For this inspection, the ignition switch must be turned on to 
run the electric fuel pump to demonstrate an operating fuel 
pressure.
    (2) If a fissure, a kink, or a leak is found during any 
inspection required by paragraph (h)(1) of this AD, before further 
flight, replace the part with an unused (zero hours TIS) serviceable 
part by following paragraphs 3 and 4 of the Instructions in TN No. 
800/46 or paragraphs 3 through 5 of the Instructions in TN No. 1000/
38, as applicable to your model glider.

(i) Life Limit
