sailplanes equipped with a SOLO 2625
engine or a Mid-West AE 50T engine.
This AD requires you to modify the
coolant pump and fuel pump electrical
circuits, remove the non-resettable
digital engine indicator (DEI) circuit
breaker (4-ampere) and replace with a
resettable 5-ampere circuit breaker,
secure (for sailplanes with a SOLO 2625
engine) the choke butterfly valve axis,
install edge protection at the sharp
edges of the resettable 5-ampere DEI
circuit breaker, and incorporate changes
in the FAA-approved sailplane flight
manual. This AD is the result of
mandatory continuing airworthiness
information (MCAI) issued by the
airworthiness authority for Germany.
We are issuing this AD to prevent
electrical failure of the fuel and coolant
pumps if a non-resettable circuit breaker
trips. This could result in power loss
with the inability to restart the fuel
pump during a critical phase of flight
(for example, takeoff under own power).
DATES: This AD becomes effective on
June 6, 2005.
As of June 6, 2005, the Director of the
Federal Register approved the
incorporation by reference of certain
publications listed in the regulation.

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD?
The Luftfahrt-Bundesamt (LBA), which
is the airworthiness authority for
Germany, recently notified FAA that an
unsafe condition may exist on DG
Flugzeugbau Model DG–800B
sailplanes. The LBA reports both
electrical circuits of the fuel pump and
the coolant pump (on a SOLO 2625
engine or a Mid-West AE 50T engine)
are protected by a non-resettable digital
engine indicator (DEI) circuit breaker.
The pumps will stop running if the nonresettable circuit breaker activates.
What is the potential impact if FAA
took no action? If a non-resettable
circuit breaker trips, this could result in
power loss with the inability to restart
the fuel pump during a critical phase of
flight (for example, takeoff under own
power).
Has FAA taken any action to this
point? We issued a proposal to amend
part 39 of the Federal Aviation
Regulations (14 CFR part 39) to include
an AD that would apply to all GlaserDirks Flugzeugbau GmbH (DG
Flugzeugbau) Model DG–800B
sailplanes equipped with a SOLO 2625
engine or a Mid-West AE 50T engine.
This proposal was published in the
Federal Register as a notice of proposed
rulemaking (NPRM) on April 12, 2004
(69 FR 19135). The NPRM proposed to
require you to modify the coolant pump
and fuel pump electrical circuits,
replace the non-resettable circuit
breaker with a resettable circuit breaker,
and (for a version of the Mikuni
carburetor) secure the choke butterfly
valve axis.
As a result of our further analysis of
the service information and determining
that important actions were omitted in
the NPRM and should be incorporated,
we issued a supplemental proposal to
amend part 39 of the Federal Aviation
Regulations (14 CFR part 39) to include
an AD that would apply to all GlaserDirks Flugzeugbau GmbH (DG
Flugzeugbau) Model DG–800B
sailplanes equipped with a SOLO 2625
engine or a Mid-West AE 50T engine
sailplanes. This proposal was published
in the Federal Register as a
supplemental NPRM on November 8,
2004 (69 FR 64692). The supplemental
NPRM proposed to require you to do the
following:
—Modify the coolant pump and fuel
pump electrical circuits;
—Remove the non-resettable digital
engine indicator (DEI) circuit breaker
(4-ampere) and replace with a
resettable 5-ampere circuit breaker;
Labor cost

—Secure the choke butterfly valve axis
that is on the SOLO 2625 engine (new
version Mikuni carburetor);
—Install edge protection at the sharp
edges of the resettable 5-ampere DEI
circuit breaker; and
—Incorporate ‘‘Flight Manual’’ changes
that are listed in the service
information.
Comments
Was the public invited to comment?
We provided the public the opportunity
to participate in developing this AD. We
received no comments on the proposal
or on the determination of the cost to
the public.
Conclusion
What is FAA’s final determination on
this issue? We have carefully reviewed
the available data and determined that
air safety and the public interest require
adopting the AD as proposed except for
minor editorial corrections. We have
determined that these minor
corrections:
—Are consistent with the intent that
was proposed in the NPRM for
correcting the unsafe condition; and
—Do not add any additional burden
upon the public than was already
proposed in the NPRM.
Changes to 14 CFR Part 39—Effect on
the AD
How does the revision to 14 CFR part
39 affect this AD? On July 10, 2002, the
FAA published a new version of 14 CFR
part 39 (67 FR 47997, July 22, 2002),
which governs the FAA’s AD system.
This regulation now includes material
that relates to altered products, special
flight permits, and alternative methods
of compliance. This material previously
was included in each individual AD.
Since this material is included in 14
CFR part 39, we will not include it in
future AD actions.
Costs of Compliance
How many sailplanes does this AD
impact? We estimate that this AD affects
25 sailplanes in the U.S. registry.
What is the cost impact of this AD on
owners/operators of the affected
sailplanes? We estimate the following
costs to do the modification:

Federal Register / Vol. 70, No. 76 / Thursday, April 21, 2005 / Rules and Regulations
Authority for This Rulemaking
What authority does FAA have for
issuing this rulemaking action? 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 AD.
Will this AD involve a significant rule
or regulatory action? For the reasons
discussed above, I certify that 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); 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 summary of the costs
to comply with this AD (and other
information as included in the
Regulatory Evaluation) and placed it in
the AD Docket. You may get a copy of
this summary by sending a request to us
at the address listed under ADDRESSES.
Include ‘‘AD Docket No. 2003–CE–65–
AD’’ in your request.
List of Subjects in 14 CFR Part 39

Regulatory Findings
Adoption of the Amendment
Will this AD impact various entities?
We have 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.

ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD),
which applies to certain McDonnell
Douglas series airplanes. That AD
currently requires repetitive inspections
of the electrical connectors of the
explosive cartridge wiring of the engine
fire extinguisher containers to verify if
the identification number labels are
installed and legible; repetitive
electrical tests of all explosive cartridge
wiring of the engine fire extinguisher
containers to verify proper installation
and function; and corrective actions if
necessary. This new AD requires an
inspection of the emergency shut off
wire assembly; installation of lanyards
on the electrical connectors for the
PO 00000
Frm 00021
Fmt 4700
Sfmt 4700
engine fire extinguishing agent
containers and for the auxiliary power
unit fire extinguishing agent containers
if applicable; and related investigative/
corrective actions, as applicable. This
AD is prompted by reports of crosswired electrical connectors of the engine
fire extinguishing agent containers. We
are issuing this AD to detect and correct
cross-wired electrical connectors of the
fire extinguishing system, which could
release fire extinguishing agent into the
incorrect engine nacelle in the event of
an engine fire.
DATES: This AD becomes effective May
26, 2005.
The incorporation by reference of a
certain publication listed in the AD is
approved by the Director of the Federal
Register as of May 26, 2005.
On December 20, 2001 (66 FR 63157,
December 5, 2001), the Director of the
Federal Register approved the
incorporation by reference of a certain
other publication listed in the AD.

Airworthiness Directives; Glaser-Dirks Flugzeugbau GmbH Model DG-
800B Sailplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA adopts a new airworthiness directive (AD) for all
Glaser-Dirks Flugzeugbau GmbH (DG Flugzeugbau) Model DG-800B
[[Page 20711]]
sailplanes equipped with a SOLO 2625 engine or a Mid-West AE 50T
engine. This AD requires you to modify the coolant pump and fuel pump
electrical circuits, remove the non-resettable digital engine indicator
(DEI) circuit breaker (4-ampere) and replace with a resettable 5-ampere
circuit breaker, secure (for sailplanes with a SOLO 2625 engine) the
choke butterfly valve axis, install edge protection at the sharp edges
of the resettable 5-ampere DEI circuit breaker, and incorporate changes
in the FAA-approved sailplane flight manual. This AD is the result of
mandatory continuing airworthiness information (MCAI) issued by the
airworthiness authority for Germany. We are issuing this AD to prevent
electrical failure of the fuel and coolant pumps if a non-resettable
circuit breaker trips. This could result in power loss with the
inability to restart the fuel pump during a critical phase of flight
(for example, takeoff under own power).
DATES: This AD becomes effective on June 6, 2005.
As of June 6, 2005, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in the
regulation.

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD? The Luftfahrt-Bundesamt (LBA),
which is the airworthiness authority for Germany, recently notified FAA
that an unsafe condition may exist on DG Flugzeugbau Model DG-800B
sailplanes. The LBA reports both electrical circuits of the fuel pump
and the coolant pump (on a SOLO 2625 engine or a Mid-West AE 50T
engine) are protected by a non-resettable digital engine indicator
(DEI) circuit breaker. The pumps will stop running if the non-
resettable circuit breaker activates.
What is the potential impact if FAA took no action? If a non-
resettable circuit breaker trips, this could result in power loss with
the inability to restart the fuel pump during a critical phase of
flight (for example, takeoff under own power).
Has FAA taken any action to this point? We issued a proposal to
amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to
include an AD that would apply to all Glaser-Dirks Flugzeugbau GmbH (DG
Flugzeugbau) Model DG-800B sailplanes equipped with a SOLO 2625 engine
or a Mid-West AE 50T engine. This proposal was published in the Federal
Register as a notice of proposed rulemaking (NPRM) on April 12, 2004
(69 FR 19135). The NPRM proposed to require you to modify the coolant
pump and fuel pump electrical circuits, replace the non-resettable
circuit breaker with a resettable circuit breaker, and (for a version
of the Mikuni carburetor) secure the choke butterfly valve axis.
As a result of our further analysis of the service information and
determining that important actions were omitted in the NPRM and should
be incorporated, we issued a supplemental proposal to amend part 39 of
the Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to all Glaser-Dirks Flugzeugbau GmbH (DG Flugzeugbau) Model
DG-800B sailplanes equipped with a SOLO 2625 engine or a Mid-West AE
50T engine sailplanes. This proposal was published in the Federal
Register as a supplemental NPRM on November 8, 2004 (69 FR 64692). The
supplemental NPRM proposed to require you to do the following:
--Modify the coolant pump and fuel pump electrical circuits;
--Remove the non-resettable digital engine indicator (DEI) circuit
breaker (4-ampere) and replace with a resettable 5-ampere circuit
breaker;
--Secure the choke butterfly valve axis that is on the SOLO 2625 engine
(new version Mikuni carburetor);
--Install edge protection at the sharp edges of the resettable 5-ampere
DEI circuit breaker; and
--Incorporate ``Flight Manual'' changes that are listed in the service
information.
Comments
Was the public invited to comment? We provided the public the
opportunity to participate in developing this AD. We received no
comments on the proposal or on the determination of the cost to the
public.
Conclusion
What is FAA's final determination on this issue? We have carefully
reviewed the available data and determined that air safety and the
public interest require adopting the AD as proposed except for minor
editorial corrections. We have determined that these minor corrections:
--Are consistent with the intent that was proposed in the NPRM for
correcting the unsafe condition; and
--Do not add any additional burden upon the public than was already
proposed in the NPRM.
Changes to 14 CFR Part 39--Effect on the AD
How does the revision to 14 CFR part 39 affect this AD? On July 10,
2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997,
July 22, 2002), which governs the FAA's AD system. This regulation now
includes material that relates to altered products, special flight
permits, and alternative methods of compliance. This material
previously was included in each individual AD. Since this material is
included in 14 CFR part 39, we will not include it in future AD
actions.
Costs of Compliance
How many sailplanes does this AD impact? We estimate that this AD
affects 25 sailplanes in the U.S. registry.
What is the cost impact of this AD on owners/operators of the
affected sailplanes? We estimate the following costs to do the
modification:
----------------------------------------------------------------------------------------------------------------
Total cost
Labor cost Parts cost per Total cost on U.S.
sailplane operators
----------------------------------------------------------------------------------------------------------------
6 workhours at $65 per hour = $390........................ $100 $490 25 x $490 = $12,250
----------------------------------------------------------------------------------------------------------------

Authority for This Rulemaking
What authority does FAA have for issuing this rulemaking action?
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 AD.
Regulatory Findings
Will this AD impact various entities? We have 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.
Will this AD involve a significant rule or regulatory action? For
the reasons discussed above, I certify that 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); 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 summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``AD
Docket No. 2003-CE-65-AD'' in your request.
