Airworthiness Directives; Fokker

0100 Airplanes
AGENCY: Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for the
products listed above. 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:
Several incidents have been reported
where an electrical burning smell was noted
in the cockpit, originating from the Electrical
Power Centre. Troubleshooting revealed a
partly molten terminal, which normally
attaches a wire or bus bar to a stud of an
Electrical Power Contactor, Part Number
(P/N) SG02206. Furthermore, heat damage to
the contactor stud itself was found. * * *
*
*
*
*
*
This condition, if not corrected, could lead
to further cases of overheating of terminals
and studs of Electrical Power Contactors
P/N SG02206, possibly resulting in the loss
of electrical power systems, electrical arcing
and fire/smoke in the cockpit.
The proposed AD would require
actions that are intended to address the
unsafe condition described in the MCAI.
DATES: We must receive comments on
this proposed AD by July 2, 2009.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2008–0091,
dated May 13, 2008 (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
Several incidents have been reported
where an electrical burning smell was noted
in the cockpit, originating from the Electrical
Power Centre. Troubleshooting revealed a
partly molten terminal, which normally
attaches a wire or bus bar to a stud of an
Electrical Power Contactor, Part Number
(P/N) SG02206. Furthermore, heat damage to
the contactor stud itself was found. Material
investigation revealed that the terminal,
which was attached to the stud, was not
properly torque tightened when the incident
occurred. Loss of torque is considered to
have occurred during operation, for reasons
not fully understood. Further loosening may
have taken place in-service under influence
of vibration. As a result, poor contact caused
electrical arcing during which extremely high
temperatures were developed, leading to
partial melting of the terminal.
Investigation of some other burned
contactors revealed evidence (flat spring lock
washer) of a fully torqued terminal/stud
connection when the overheating occurred.
The exact cause for the increase in
temperature in the contactor and the
terminal/stud could not be determined.
However, it could not be excluded that an
increase of the temperature inside the
contactor could lead to reduction of the
reliability of the contactor stud/terminal
connection due to loss of lock washer
tension. The affected Electrical Power
Contactor is used on several locations in the
electrical power system, i.e. Generator Line
Contactor (GLC), Bus Tie Contactor (BTC),
Auxiliary Power Contactor (APC) and
External Power Contactor (EPC).

Federal Register / Vol. 74, No. 104 / Tuesday, June 2, 2009 / Proposed Rules
This condition, if not corrected, could lead
to further cases of overheating of terminals
and studs of Electrical Power Contactors P/
N SG02206, possibly resulting in the loss of
electrical power systems, electrical arcing
and fire/smoke in the cockpit.
For the reasons described above, this EASA
Airworthiness Directive (AD) requires the
replacement of the current nut and spring
washer of the standard contactor P/N
SG02206 with a new self-locking nut.
You may obtain further information
by examining the MCAI in the AD
docket.

FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
PO 00000
Frm 00022
Fmt 4702
Sfmt 4702
in the United States. Pursuant to our
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
E:\FR\FM\02JNP1.SGM
02JNP1
26324
Federal Register / Vol. 74, No. 104 / Tuesday, June 2, 2009 / Proposed Rules
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
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 proposed
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
proposed AD.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 5 products of U.S. registry.
We also estimate that it would take
about 8 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour. Required
parts would cost about $5,715 per
product. Where the service information
lists required parts costs that are
covered under warranty, we have
assumed that there will be no charge for
these costs. As we do not control
warranty coverage for affected parties,
some parties may incur costs higher
than estimated here. Based on these
figures, we estimate the cost of the
proposed AD on U.S. operators to be
$31,775, or $6,355 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
VerDate Nov<24>2008
16:00 Jun 01, 2009
Jkt 217001
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); 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 proposed AD and placed it in the
AD docket.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation

Subject
(d) Air Transport Association (ATA) of
America Code 24: Electrical power.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Several incidents have been reported
where an electrical burning smell was noted
in the cockpit, originating from the Electrical
Power Centre. Troubleshooting revealed a
partly molten terminal, which normally
attaches a wire or bus bar to a stud of an
Electrical Power Contactor, Part Number
(P/N) SG02206. Furthermore, heat damage to
the contactor stud itself was found. Material
investigation revealed that the terminal,
which was attached to the stud, was not
properly torque tightened when the incident
occurred. Loss of torque is considered to
have occurred during operation, for reasons
not fully understood. Further loosening may
have taken place in-service under influence
of vibration. As a result, poor contact caused
electrical arcing during which extremely high
temperatures were developed, leading to
partial melting of the terminal.
Investigation of some other burned
contactors revealed evidence (flat spring lock
washer) of a fully torqued terminal/stud
connection when the overheating occurred.
The exact cause for the increase in
temperature in the contactor and the
terminal/stud could not be determined.
However, it could not be excluded that an
increase of the temperature inside the
contactor could lead to reduction of the
reliability of the contactor stud/terminal
connection due to loss of lock washer
tension. The affected Electrical Power
Contactor is used on several locations in the
electrical power system, i.e. Generator Line
Contactor (GLC), Bus Tie Contactor (BTC),
Auxiliary Power Contactor (APC) and
External Power Contactor (EPC).
This condition, if not corrected, could lead
to further cases of overheating of terminals
and studs of Electrical Power Contactors
P/N SG02206, possibly resulting in the loss
of electrical power systems, electrical arcing
and fire/smoke in the cockpit.
For the reasons described above, this EASA
Airworthiness Directive (AD) requires the
replacement of the current nut and spring
washer of the standard contactor P/N
SG02206 with a new self-locking nut.
Actions and Compliance
(f) Unless already done, do the following
actions:
(1) Except as provided by paragraphs (f)(2)
and (f)(3) of this AD: Within 36 months after
the effective date of this AD, remove the
standard nuts and lock washers from the
contactors having part number (P/N)
SG02206, install new self-locking nuts, and
perform the applicable tests on the
Alternating Current Bus Transfer system, in
accordance with the Accomplishment
Instructions of Fokker Service Bulletin
SBF100–24–041 or SBF50–24–031, both
dated January 29, 2008, as applicable. If any
test fails, before further flight, repair using a
method approved by either the Manager,
International Branch, ANM–116, Transport
Airplane Directorate, FAA; or EASA (or its
delegated agent).

Federal Register / Vol. 74, No. 104 / Tuesday, June 2, 2009 / Proposed Rules
(2) Accomplishment of paragraph (f)(1) of
this AD is not required for Model F.28 Mark
0100 airplanes that have been modified in
service in accordance with Fokker Service
Bulletin SBF100–24–037, dated October 2,
2003. Accomplishment of Fokker Service
Bulletin SBF100–24–037, dated October 2,
2003, within the compliance time specified
in paragraph (f)(1) of this AD is considered
an acceptable method of compliance with the
requirements of paragraph (f)(1) of this AD.
(3) Accomplishment of paragraph (f)(1) of
this AD is not required for Model F.27 Mark
050 airplanes that have been modified during
production to incorporate Fokker
Engineering Change Record (ECR) 51780, or
for airplanes that have been modified in
service in accordance with Fokker Service
Bulletin SBF50–24–030, dated November 6,
2003. Accomplishment of Fokker Service
Bulletin SBF50–24–030, dated November 6,
2003, within the compliance time specified
in paragraph (f)(1) of this AD is considered
an acceptable method of compliance with the
requirements of paragraph (f)(1) of this AD.
(4) As of 36 months after the effective date
of this AD, no person may install a contactor
having P/N SG02206 on any airplane unless
it has been modified in accordance with
Goodrich Power Systems Service Bulletin
SG02206–24–01, dated March 4, 2008.
FAA AD Differences
Note 1: This AD differs from the MCAI
and/or service information as follows: The
MCAI does not include a corrective action for
airplanes on which the test required by
paragraph (f)(1) of this AD fails. This AD
requires the corrective action specified in
paragraph (f)(1) of this AD.
Other FAA AD Provisions
(g) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, International
Branch, 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: Tom Rodriguez,
Aerospace Engineer, International Branch,
ANM–116, Transport Airplane Directorate,
FAA, 1601 Lind Avenue SW., Renton,
Washington 98057–3356; telephone (425)
227–1137; fax (425) 227–1149. Before using
any approved AMOC on any airplane to
which the AMOC applies, notify your
appropriate principal maintenance inspector
(PMI) or principal avionics inspector (PAI),
as appropriate, or lacking a principal
inspector, your local flight Standards District
Office.
(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, under the
provisions of the Paperwork Reduction Act,
the Office of Management and Budget (OMB)
has approved the information collection
requirements and has assigned OMB Control
Number 2120–0056.

Airworthiness Directives; Fokker Model F.27 Mark 050 and F.28
Mark 0100 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. 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:
Several incidents have been reported where an electrical burning
smell was noted in the cockpit, originating from the Electrical
Power Centre. Troubleshooting revealed a partly molten terminal,
which normally attaches a wire or bus bar to a stud of an Electrical
Power Contactor, Part Number (P/N) SG02206. Furthermore, heat damage
to the contactor stud itself was found. * * *
* * * * *
This condition, if not corrected, could lead to further cases of
overheating of terminals and studs of Electrical Power Contactors P/
N SG02206, possibly resulting in the loss of electrical power
systems, electrical arcing and fire/smoke in the cockpit.
The proposed AD would require actions that are intended to address
the unsafe condition described in the MCAI.
DATES: We must receive comments on this proposed AD by July 2, 2009.
ADDRESSES: You may send comments by any of the following methods:

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2008-0091, dated May 13, 2008 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
Several incidents have been reported where an electrical burning
smell was noted in the cockpit, originating from the Electrical
Power Centre. Troubleshooting revealed a partly molten terminal,
which normally attaches a wire or bus bar to a stud of an Electrical
Power Contactor, Part Number (P/N) SG02206. Furthermore, heat damage
to the contactor stud itself was found. Material investigation
revealed that the terminal, which was attached to the stud, was not
properly torque tightened when the incident occurred. Loss of torque
is considered to have occurred during operation, for reasons not
fully understood. Further loosening may have taken place in-service
under influence of vibration. As a result, poor contact caused
electrical arcing during which extremely high temperatures were
developed, leading to partial melting of the terminal.
Investigation of some other burned contactors revealed evidence
(flat spring lock washer) of a fully torqued terminal/stud
connection when the overheating occurred. The exact cause for the
increase in temperature in the contactor and the terminal/stud could
not be determined. However, it could not be excluded that an
increase of the temperature inside the contactor could lead to
reduction of the reliability of the contactor stud/terminal
connection due to loss of lock washer tension. The affected
Electrical Power Contactor is used on several locations in the
electrical power system, i.e. Generator Line Contactor (GLC), Bus
Tie Contactor (BTC), Auxiliary Power Contactor (APC) and External
Power Contactor (EPC).
[[Page 26323]]
This condition, if not corrected, could lead to further cases of
overheating of terminals and studs of Electrical Power Contactors P/
N SG02206, possibly resulting in the loss of electrical power
systems, electrical arcing and fire/smoke in the cockpit.
For the reasons described above, this EASA Airworthiness
Directive (AD) requires the replacement of the current nut and
spring washer of the standard contactor P/N SG02206 with a new self-
locking nut.
You may obtain further information by examining the MCAI in the AD
docket.

The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of This 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 the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information
[[Page 26324]]
referenced above. We are proposing this AD because we evaluated all
pertinent information and determined an unsafe condition exists and is
likely to exist or develop on other products of the same type design.
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 proposed 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 proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 5 products of U.S. registry. We also estimate that
it would take about 8 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Required parts would cost about $5,715 per product. Where
the service information lists required parts costs that are covered
under warranty, we have assumed that there will be no charge for these
costs. As we do not control warranty coverage for affected parties,
some parties may incur costs higher than estimated here. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $31,775, or $6,355 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 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); 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 proposed AD and placed it in the AD docket.

which normally attaches a wire or bus bar to a stud of an Electrical
Power Contactor, Part Number (P/N) SG02206. Furthermore, heat damage
to the contactor stud itself was found. Material investigation
revealed that the terminal, which was attached to the stud, was not
properly torque tightened when the incident occurred. Loss of torque
is considered to have occurred during operation, for reasons not
fully understood. Further loosening may have taken place in-service
under influence of vibration. As a result, poor contact caused
electrical arcing during which extremely high temperatures were
developed, leading to partial melting of the terminal.
Investigation of some other burned contactors revealed evidence
(flat spring lock washer) of a fully torqued terminal/stud
connection when the overheating occurred. The exact cause for the
increase in temperature in the contactor and the terminal/stud could
not be determined. However, it could not be excluded that an
increase of the temperature inside the contactor could lead to
reduction of the reliability of the contactor stud/terminal
connection due to loss of lock washer tension. The affected
Electrical Power Contactor is used on several locations in the
electrical power system, i.e. Generator Line Contactor (GLC), Bus
Tie Contactor (BTC), Auxiliary Power Contactor (APC) and External
Power Contactor (EPC).
This condition, if not corrected, could lead to further cases of
overheating of terminals and studs of Electrical Power Contactors P/
N SG02206, possibly resulting in the loss of electrical power
systems, electrical arcing and fire/smoke in the cockpit.
For the reasons described above, this EASA Airworthiness
Directive (AD) requires the replacement of the current nut and
spring washer of the standard contactor P/N SG02206 with a new self-
locking nut.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Except as provided by paragraphs (f)(2) and (f)(3) of this
AD: Within 36 months after the effective date of this AD, remove the
standard nuts and lock washers from the contactors having part
number (P/N) SG02206, install new self-locking nuts, and perform the
applicable tests on the Alternating Current Bus Transfer system, in
accordance with the Accomplishment Instructions of Fokker Service
Bulletin SBF100-24-041 or SBF50-24-031, both dated January 29, 2008,
as applicable. If any test fails, before further flight, repair
using a method approved by either the Manager, International Branch,
ANM-116, Transport Airplane Directorate, FAA; or EASA (or its
delegated agent).
[[Page 26325]]
(2) Accomplishment of paragraph (f)(1) of this AD is not
required for Model F.28 Mark 0100 airplanes that have been modified
in service in accordance with Fokker Service Bulletin SBF100-24-037,
dated October 2, 2003. Accomplishment of Fokker Service Bulletin
SBF100-24-037, dated October 2, 2003, within the compliance time
specified in paragraph (f)(1) of this AD is considered an acceptable
method of compliance with the requirements of paragraph (f)(1) of
this AD.
(3) Accomplishment of paragraph (f)(1) of this AD is not
required for Model F.27 Mark 050 airplanes that have been modified
during production to incorporate Fokker Engineering Change Record
(ECR) 51780, or for airplanes that have been modified in service in
accordance with Fokker Service Bulletin SBF50-24-030, dated November
6, 2003. Accomplishment of Fokker Service Bulletin SBF50-24-030,
dated November 6, 2003, within the compliance time specified in
paragraph (f)(1) of this AD is considered an acceptable method of
compliance with the requirements of paragraph (f)(1) of this AD.
(4) As of 36 months after the effective date of this AD, no
person may install a contactor having P/N SG02206 on any airplane
unless it has been modified in accordance with Goodrich Power
Systems Service Bulletin SG02206-24-01, dated March 4, 2008.
FAA AD Differences
Note 1: This AD differs from the MCAI and/or service
information as follows: The MCAI does not include a corrective
action for airplanes on which the test required by paragraph (f)(1)
of this AD fails. This AD requires the corrective action specified
in paragraph (f)(1) of this AD.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, 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: Tom Rodriguez, Aerospace Engineer,
International Branch, ANM-116, Transport Airplane Directorate, FAA,
1601 Lind Avenue SW., Renton, Washington 98057-3356; telephone (425)
227-1137; fax (425) 227-1149. Before using any approved AMOC on any
airplane to which the AMOC applies, notify your appropriate
principal maintenance inspector (PMI) or principal avionics
inspector (PAI), as appropriate, or lacking a principal inspector,
your local flight Standards District Office.
(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, under the provisions of the Paperwork Reduction Act, the
Office of Management and Budget (OMB) has approved the information
collection requirements and has assigned OMB Control Number 2120-
0056.
