AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Fokker Model F27 Mark 050 airplanes
equipped with Dowty Type R.352 or
R.410 series propellers. This AD
requires checking the maintenance
records to determine whether Minnesota
Mining and Manufacture Co. (3M)
1300L adhesive was used to attach the
de-icer assembly overshoes (boots) to
the propeller blades, repetitive
inspections of affected boots, and
replacing boots attached with defective
adhesive. This AD results from three
events of propeller blade de-icer
assembly boots debonding and
detaching during flight. This condition
was caused by using 3M 1300L adhesive
to attach the boot to the propeller blade.
We are issuing this AD to detect and

correct boots attached with defective
adhesive, which could result in
debonding and separation of a boot from
the airplane, consequent reduced
structural integrity of the airplane, and
possible injury to passengers and crew.
DATES: This AD becomes effective
August 24, 2007.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD

SUPPLEMENTARY INFORMATION:
Discussion
The Civil Aviation Authority-The
Netherlands (CAA–NL), which is the
airworthiness authority for the
Netherlands, notified us that an unsafe
condition may exist on certain Fokker
Model F27 Mark 050 airplanes equipped
with Dowty Type R.352 or R.410 series
propellers. The CAA–NL advises that
there have been three events of
propeller blade de-icer assembly boots
debonding and detaching during flight.
In two of the incidents, the boot
impacted the fuselage causing
considerable damage, but did not
penetrate into the fuselage. In the third
incident the boot hit a passenger cabin
E:\FR\FM\09AUR1.SGM
09AUR1
Federal Register / Vol. 72, No. 153 / Thursday, August 9, 2007 / Rules and Regulations
window shattering the pane and
penetrating into the fuselage, and
subsequently injuring two passengers.
Investigation revealed that all of the
affected boots had been attached using
Minnesota Mining and Manufacture Co.
(3M) 1300L adhesive. This condition, if
not corrected, could result in debonding
and separation of a boot from the
airplane, consequent reduced structural
integrity of the airplane, and possible
injury to passengers and crew.
Relevant Service Information
Dowty has issued Service Bulletin
F50–61–158, including Appendix 1,
dated September 30, 2005. The service
bulletin describes procedures for
checking the maintenance records to
determine whether 3M 1300L adhesive
has been applied to attach the de-icer
assembly overshoes (boots) to the
propeller blades, repetitive inspections
of affected boots, and replacing boots
attached with defective adhesive.
Accomplishing the actions specified in
the service information is intended to
adequately address the unsafe
condition. The CAA–NL reviewed the
service information and issued Dutch
airworthiness directive NL–2005–016,
dated December 16, 2005, to ensure the
continued airworthiness of these
airplanes in the Netherlands.
jlentini on PROD1PC65 with RULES
FAA’s Determination and Requirements
of This AD
These airplanes are manufactured in
the Netherlands and are type
certificated for operation in the United
States under the provisions of section
21.29 of the Federal Aviation
Regulations (14 CFR 21.29) and the
applicable bilateral airworthiness
agreement. Pursuant to this bilateral
airworthiness agreement, the CAA–NL
has kept the FAA informed of the
situation described above. We have
examined the CAA–NL’s findings,
evaluated all pertinent information, and
determined that we need to issue an AD
for products of this type design that are
certificated for operation in the United
States.
Therefore, we are issuing this AD to
detect and correct boots with defective
adhesive, which could result in
separation of a boot from the airplane,
possible injury to passengers and crew,
and consequent reduced structural
integrity of the airplane. This AD
requires accomplishing the actions
specified in the service information
described previously.
Costs of Compliance
None of the airplanes affected by this
action are on the U.S. Register. All
airplanes affected by this AD are
VerDate Aug<31>2005
17:01 Aug 08, 2007
Jkt 211001
currently operated by non-U.S.
operators under foreign registry;
therefore, they are not directly affected
by this AD action. However, we
consider this AD necessary to ensure
that the unsafe condition is addressed if
any affected airplane is imported and
placed on the U.S. Register in the future.
If an affected airplane is imported and
placed on the U.S. Register in the future,
the required inspections would take
about 1 work hour per airplane, at an
average labor rate of $80 per work hour.
Based on these figures, the estimated
cost of the AD would be $80 per
airplane, per inspection cycle.
FAA’s Determination of the Effective
Date
No airplane affected by this AD is
currently on the U.S. Register.
Therefore, providing notice and
opportunity for public comment is
unnecessary before this AD is issued,
and this AD may be made effective in
less than 30 days after it is published in
the Federal Register.
Comments Invited
This AD is a final rule that involves
requirements that affect flight safety and
was not preceded by notice and an
opportunity for public comment;

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 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.
For the reasons discussed above, I
certify that the 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 AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

ACTION: Final rule.
AGENCY:
SUMMARY: We are adopting a new
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:
* * * some structural areas have been
identified for which existing recommended
SB (service bulletin) needs to be rendered
mandatory.
As a consequence, and because it has been
shown that the torque applied to the tension
bolts connecting the beam (stringer 49) to the
forward and aft beam extension at FR11 and
FR17 may be insufficient, this AD renders
mandatory the replacement of those tension
bolts, in order to limit the risks of damage or
corrosion of the specified areas.
Damage or corrosion of the specified
areas could result in reduced structural
integrity of the airplane. We are issuing
this AD to require actions to correct the
unsafe condition on these products.
DATES: This AD becomes effective
September 13, 2007.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of September 13, 2007.

the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the CAA-NL has kept the FAA informed
of the situation described above. We have examined the CAA-NL's
findings, evaluated all pertinent information, and determined that we
need to issue an AD for products of this type design that are
certificated for operation in the United States.
Therefore, we are issuing this AD to detect and correct boots with
defective adhesive, which could result in separation of a boot from the
airplane, possible injury to passengers and crew, and consequent
reduced structural integrity of the airplane. This AD requires
accomplishing the actions specified in the service information
described previously.
Costs of Compliance
None of the airplanes affected by this action are on the U.S.
Register. All airplanes affected by this AD are currently operated by
non-U.S. operators under foreign registry; therefore, they are not
directly affected by this AD action. However, we consider this AD
necessary to ensure that the unsafe condition is addressed if any
affected airplane is imported and placed on the U.S. Register in the
future.
If an affected airplane is imported and placed on the U.S. Register
in the future, the required inspections would take about 1 work hour
per airplane, at an average labor rate of $80 per work hour. Based on
these figures, the estimated cost of the AD would be $80 per airplane,
per inspection cycle.
FAA's Determination of the Effective Date
No airplane affected by this AD is currently on the U.S. Register.
Therefore, providing notice and opportunity for public comment is
unnecessary before this AD is issued, and this AD may be made effective
in less than 30 days after it is published in the Federal Register.
Comments Invited
This AD is a final rule that involves requirements that affect
flight safety and was not preceded by notice and an opportunity for
public comment; however, we invite you to submit any relevant written
data, views, or arguments regarding this AD. Send your comments to an
address listed in the ADDRESSES section. Include ``Docket No. FAA-2007-
28911; Directorate Identifier 2007-NM-002-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the AD that might
suggest a need to modify it.
We will post all comments we receive, without change, to https://
dms.dot.gov, including any personal information you provide. We will
also post a report summarizing each substantive verbal contact with FAA
personnel concerning this AD. Using the search function of that Web
site, anyone can find and read the comments in any of our dockets,
including the name of the individual who sent the comment (or signed
the comment on behalf of an association, business, labor union, etc.).
You may review the DOT's complete Privacy Act Statement in the Federal
Register published on April 11, 2000 (65 FR 19477-78), or you may visit

Examining the Docket
You may examine the AD docket on the Internet at https://
dms.dot.gov, or in person at the Docket Operations office between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The
Docket Operations office (telephone (800) 647-5527) is located on the
ground floor of the West Building at the street address stated in the
ADDRESSES section. Comments will be available in the AD docket shortly
after the Docket Management System receives them.
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 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.
For the reasons discussed above, I certify that the 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 AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.

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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
2007-16-11 Fokker Services B.V.: Amendment 39-15150. Docket No. FAA-
2007-28911; Directorate Identifier 2007-NM-002-AD.
Effective Date
(a) This AD becomes effective August 24, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Fokker Model F27 Mark 050 airplanes,
certificated in any category; equipped with Dowty Type R.352 or
R.410 series propellers.
Unsafe Condition
(d) This AD results from three events of propeller blade de-icer
assembly overshoes (boots) debonding and detaching during flight.
This condition was caused by using Minnesota Mining and Manufacture
Co. (3M) 1300L adhesive to attach the boots to the propeller blade.
We are issuing this AD to detect and correct boots attached with
defective adhesive, which could result in debonding and separation
of a boot from the airplane, consequent reduced structural integrity
of the airplane, and possible injury to passengers and crew.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Identification of Affected Boots/Repetitive Inspections/Replacement
(f) Within 30 days after the effective date of this AD: Check
the maintenance records to determine whether 3M 1300L adhesive was
used to attach the de-icer assembly boots to the propeller blades.
(1) If 3M 1300L adhesive was not used: No further action is
required by this paragraph.
(2) If 3M 1300L adhesive was used, or the type of adhesive
cannot be determined: Within 650 flight hours, do a general visual
inspection for signs of lifting or bubbling of the adhesive in
accordance with the Accomplishment Instructions of Dowty Service
Bulletin F50-61-158, including Appendix 1, dated September 30, 2005.
(i) If no signs of lifting or bubbling are found: Repeat the
inspection at intervals not to exceed 650 flight hours.
(ii) If any signs of lifting or bubbling are found: Before
further flight, replace the affected de-icer assembly boot in
accordance with Accomplishment Instructions of the service bulletin.
Note 1: For the purposes of this AD, a general visual inspection
is: ``A visual examination of an interior or exterior area,
installation, or assembly to detect obvious damage, failure, or
irregularity. This level of inspection is made from within touching
distance unless otherwise specified. A mirror may be necessary to
ensure visual access to all surfaces in the inspection area. This
level of inspection is made under normally available lighting
conditions such as daylight, hangar lighting, flashlight, or
droplight and may require removal or opening of access panels or
doors. Stands, ladders, or platforms may be required to gain
proximity to the area being checked.''
Parts Installation
(g) As of the effective date of this AD, no person may use 3M
1300L adhesive to attach a boot to the propeller blade, on any
airplane.
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, International Branch, Transport Airplane
Directorate, FAA, has the authority to approve AMOCs for this AD, if
requested in accordance with the procedures found in 14 CFR 39.19.
(2) To request a different method of compliance or a different
compliance time for this AD, follow the procedures in 14 CFR 39.19.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
