additional special conditions may
apply.
10. The inflatable restraints must
function properly after loss of normal
airplane electrical power and after a
transverse separation of the fuselage at
the most critical location. A separation
at the location of the lap belt does not
have to be considered.
11. It must be shown that the
inflatable restraints will not release
hazardous quantities of gas or
particulate matter into the cabin.
12. The inflatable restraints
installation must be protected from the
effects of fire such that no hazard to
occupants will result.
13. The system must be protected
from lightning and HIRF. The threats
specified in Special Conditions No. 25–
ANM–23 are incorporated by reference
for the purpose of measuring lightning
and HIRF protection. For the purposes
of complying with HIRF requirements,
the inflatable lapbelt system is
considered a critical system if its
deployment could have a hazardous
effect on the airplane; otherwise it is
considered an essential system.
14. There must be a means for a
crewmember to verify the integrity of
the inflatable restraints activation
system prior to each flight or it must be
demonstrated to reliably operate
between inspection intervals.
15. The inflatable material may not
have an average burn rate of greater than
2.5 inches/minute when tested using the
horizontal flammability test as defined
in 14 CFR part 25, appendix F, part I,
paragraph (b)(5).

SUMMARY: We are superseding an
existing airworthiness directive (AD) for
the products listed above. This 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:
*
*
*
*
*
During recent inspections it was found that
some * * * bolts, that connect the horizontal
stabilizer control unit actuator with the doglinks, were broken. This condition, if not
corrected, could lead to [the loss of the flight
control input connection to the horizontal
stabilizer and consequent] partial loss of
control of the aircraft.
*
*
*
*
*
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
December 26, 2008.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of December 26, 2008.

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 August 7, 2008 (73 FR
45898) and proposed to supersede AD
97–13–05, Amendment 39–10051 (62
FR 34617, June 27, 1997). That NPRM
proposed to correct an unsafe condition
for the specified products. The MCAI
states:
In January 1996, Fokker issued Service
Bulletin (SB) SBF100–27–069 (referencing
Menasco, now Goodrich, SB 23100–27–19) to
introduce an inspection of bolt Part Number
(P/N) 23233–1 for cracks after the
examination of a failed bolt. This Service
Bulletin was made mandatory by CAA–NL
(Civil Aviation Authority—the Netherlands)
with the issuance of AD BLA 1996–006 (A)
[reference corresponding FAA AD 97–13–05].
PO 00000
Frm 00017
Fmt 4700
Sfmt 4700
70261
Additionally the same SB introduced a lower
torque value for these bolts.
During recent inspections it was found that
some of these bolts, that connect the
horizontal stabilizer control unit actuator
with the dog-links, were broken. This
condition, if not corrected, could lead to [the
loss of the flight control input connection to
the horizontal stabilizer and consequent]
partial loss of control of the aircraft.
Since an unsafe condition has been
identified that continues to exist or develop
on other aircraft of the same type design, this
Airworthiness Directive supersedes CAA–NL
AD 1996–006 and requires an integrity check
by a re-torque in accordance with SBF100–
27–091 and the installation of a tie wrap
through the bolt, which will act as a retainer
for the bolt and nut. The key function for this
tie-wrap is to keep the bolt in place in the
event the bolt head fails.
The corrective action includes replacing
any failed bolt (i.e., broken or loose bolt)
with a serviceable bolt. This AD also
expands the applicability of AD 97–13–
05. 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 or
on the determination of the cost to the
public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
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 our FAA
policies. Any such differences are
highlighted in a Note within the AD.
Costs of Compliance
We estimate that this AD will affect
about 9 products of U.S. registry. We
also estimate that it will take about 3
work-hours 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 this AD to the U.S. operators to
be $2,160, or $240 per product.

Federal Register / Vol. 73, No. 225 / Thursday, November 20, 2008 / Rules and Regulations
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); 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.

Effective Date
(a) This airworthiness directive (AD)
becomes effective December 26, 2008.
Affected ADs
(b) This AD supersedes AD 97–13–05,
Amendment 39–10051.
Applicability
(c) This AD applies to Fokker Model F.28
Mark 0100 airplanes, certificated in any
category, all serial numbers.
Subject
(d) Air Transport Association (ATA) of
America Code 27: Flight Controls.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
In January 1996, Fokker issued Service
Bulletin (SB) SBF100–27–069 (referencing
Menasco, now Goodrich, SB 23100–27–19) to
introduce an inspection of bolt Part Number
(P/N) 23233–1 for cracks after the
examination of a failed bolt. This Service
Bulletin was made mandatory by CAA–NL
(Civil Aviation Authority—the Netherlands)
with the issuance of AD BLA 1996–006 (A)
[reference corresponding FAA AD 97–13–05].
Additionally the same SB introduced a lower
torque value for these bolts.
During recent inspections it was found that
some of these bolts, that connect the
horizontal stabilizer control unit actuator
with the dog-links, were broken. This
condition, if not corrected, could lead to [the
loss of the flight control input connection to
the horizontal stabilizer and consequent]
partial loss of control of the aircraft.
Since an unsafe condition has been
identified that continues to exist or develop
on other aircraft of the same type design, this
Airworthiness Directive [European Aviation

2007] supersedes CAA–NL AD 1996–006 and
requires an integrity check by a re-torque in
accordance with SBF100–27–091 and the
installation of a tie wrap through the bolt,
which will act as a retainer for the bolt and
nut. The key function for this tie-wrap is to
keep the bolt in place in the event the bolt
head fails.
The corrective action includes replacing
any failed bolt (i.e., broken or loose bolt) with
a serviceable bolt.
Actions and Compliance
(f) Unless already done, within 6 months
after the effective date of this AD, do the
following actions.
(1) Perform a one-time inspection (integrity
check) for failure of the lower bolts of the
stabilizer control unit dog-links, in
accordance with the Accomplishment
Instructions of Fokker Service Bulletin
SBF100–27–091, dated August 31, 2007. If a
failed bolt is found, before further flight,
replace the bolt with a serviceable bolt in
accordance with the Accomplishment
Instructions of the service bulletin.
(2) Install a tie-wrap through the lower
bolts of the stabilizer control unit, in
accordance with the Accomplishment
Instructions of Fokker Service Bulletin
SBF100–27–091, dated August 31, 2007.

replacement of blocks made of Teflon in
the right-hand aft fuselage equipment
bay with new blocks made of Nylon 6/

Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
Changes to Note 1 and Service
Information References
The statement specified in Note 1 of
the NPRM is informational only and is
not part of the requirements of this AD.
The actions specified in that statement
are required regardless of AD action. We
have removed Note 1 of the NPRM from
this AD and revised the numbering on
the subsequent Note in this AD.
We have revised paragraph (f)(1)(iii)
of this AD to clarify that the repair may
be done in accordance with Chapter 20–
10–12 of the Gulfstream G200
Maintenance Manual, Revision 15,
dated March 31, 2008.
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 our FAA
policies. Any such differences are
highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect
about 129 products of U.S. registry. We
also estimate that it will take about 2
work-hours per product to comply with
the basic requirements of this AD. The
average labor rate is $80 per work-hour.
Required parts will cost about $54 per

We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a Note within the AD.
Costs of Compliance
We estimate that this AD will affect about 9 products of U.S.
registry. We also estimate that it will take about 3 work-hours 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 this AD to the U.S. operators to be $2,160, 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 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 AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at https://
www.regulations.gov; or in person at the Docket Operations office
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 Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

reference, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing Amendment 39-10051 (62 FR
34617, June 27, 1997) and adding the following new AD:
2008-22-14 Fokker Services B.V.: Amendment 39-15710. Docket No. FAA-
2008-0850; Directorate Identifier 2007-NM-342-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December
26, 2008.
Affected ADs
(b) This AD supersedes AD 97-13-05, Amendment 39-10051.
Applicability
(c) This AD applies to Fokker Model F.28 Mark 0100 airplanes,
certificated in any category, all serial numbers.
Subject
(d) Air Transport Association (ATA) of America Code 27: Flight
Controls.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
In January 1996, Fokker issued Service Bulletin (SB) SBF100-27-
069 (referencing Menasco, now Goodrich, SB 23100-27-19) to introduce
an inspection of bolt Part Number (P/N) 23233-1 for cracks after the
examination of a failed bolt. This Service Bulletin was made
mandatory by CAA-NL (Civil Aviation Authority--the Netherlands) with
the issuance of AD BLA 1996-006 (A) [reference corresponding FAA AD
97-13-05]. Additionally the same SB introduced a lower torque value
for these bolts.
During recent inspections it was found that some of these bolts,
that connect the horizontal stabilizer control unit actuator with
the dog-links, were broken. This condition, if not corrected, could
lead to [the loss of the flight control input connection to the
horizontal stabilizer and consequent] partial loss of control of the
aircraft.
Since an unsafe condition has been identified that continues to
exist or develop on other aircraft of the same type design, this
Airworthiness Directive [European Aviation Safety Agency (EASA)
Airworthiness Directive 2007-0287, dated November 15, 2007]
supersedes CAA-NL AD 1996-006 and requires an integrity check by a
re-torque in accordance with SBF100-27-091 and the installation of a
tie wrap through the bolt, which will act as a retainer for the bolt
and nut. The key function for this tie-wrap is to keep the bolt in
place in the event the bolt head fails.
The corrective action includes replacing any failed bolt (i.e.,
broken or loose bolt) with a serviceable bolt.
Actions and Compliance
(f) Unless already done, within 6 months after the effective
date of this AD, do the following actions.
(1) Perform a one-time inspection (integrity check) for failure
of the lower bolts of the stabilizer control unit dog-links, in
accordance with the Accomplishment Instructions of Fokker Service
Bulletin SBF100-27-091, dated August 31, 2007. If a failed bolt is
found, before further flight, replace the bolt with a serviceable
bolt in accordance with the Accomplishment Instructions of the
service bulletin.
(2) Install a tie-wrap through the lower bolts of the stabilizer
control unit, in accordance with the Accomplishment Instructions of
Fokker Service Bulletin SBF100-27-091, dated August 31, 2007.
FAA AD Differences
