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 Fokker Model
F27 Mark 050 and Model F.28 Mark
0070 and 0100 airplanes with escape
rope assemblies in the flight
compartment. The CAA–NL advises that
some operators reported finding small
cracks in the polyester assembly block
in which the cotton escape rope is
stored. To establish the strength of the
escape rope in the flight compartment
after subsequent repair of the assembly
block, a tensile test was done which
revealed that the ropes had deteriorated
over time, and the load bearing
capability was considerably reduced.
Correcting this condition would ensure
that the flightcrew safely reach the
ground after exiting the flight
compartment window during an
emergency evacuation.
Relevant Service Information
Fokker Services B.V. has issued
Fokker Service Bulletin SBF50–25–059
(for Model F27 Mark 050 airplanes) and
Fokker Service Bulletin SBF100–25–099
(for Model F.28 Mark 0070 and 0100
airplanes), both dated June 28, 2004.
The service bulletins describe
procedures for removing the two
existing escape rope assemblies in the
flight compartment and installing new
escape rope assemblies. The service
bulletins also specify sending the
removed escape ropes to Fokker
Services B.V. Accomplishing the actions
specified in the service information is
intended to adequately address the
unsafe condition. The CAA–NL
mandated the service information and
issued Dutch airworthiness directive
2004–159, dated December 24, 2004, to
ensure the continued airworthiness of
these airplanes in the Netherlands.
FAA’s Determination and Requirements
of the Proposed AD
These airplane models 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 airplanes of this type design that are
PO 00000
Frm 00005
Fmt 4702
Sfmt 4702
37511
certificated for operation in the United
States.
Therefore, we are proposing this AD,
which would require accomplishing the
actions specified in the service
information described previously,
except as discussed under ‘‘Differences
Among Proposed AD, Dutch
Airworthiness Directive, and Service
Information.’’
Differences Among Proposed AD, Dutch
Airworthiness Directive, and Service
Information
The Dutch airworthiness directive
requires amending the airplane
maintenance schedule within one year
after the effective date of the Dutch
airworthiness directive to include a new
discard task for the escape ropes after 6
years time-in-service. However, this
proposed AD does not mandate a
change to the maintenance schedule,
but would instead require repeating the
removal of the existing escape rope
assemblies and installation of new
escape rope assemblies every 72
months. These actions are essentially
the same as the discard task (which
would include replacement after
discarding the escape ropes) required by
the Dutch airworthiness directive.
Although the Accomplishment
Instructions of the referenced service
bulletins describe procedures for
sending the escape ropes to Fokker
Service B.V. after removal, this
proposed AD would not require those
actions. We do not have the authority to
direct operators to return defective
components to the parts manufacturer;
we can only require repair or
replacement of defective components
that are installed on the airplane.
Costs of Compliance
This proposed AD would affect about
2 airplanes of U.S. registry. The
proposed removal and installation
would take about 2 work hours per
airplane, at an average labor rate of $80
per work hour. Required parts would
cost between $387 and $425 per
airplane, depending on airplane
configuration. Based on these figures,
the estimated cost of the proposed AD
for U.S. operators is between $1,094 and
$1,170, or between $547 and $585 per
airplane, per removal and installation.
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.
E:\FR\FM\30JNP1.SGM
30JNP1
37512
Federal Register / Vol. 71, No. 126 / Friday, June 30, 2006 / Proposed Rules
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
Unsafe Condition
(d) This AD results from reports of findings
of small cracks in the polyester assembly
block in which the cotton escape rope is
stored. A test revealed that the escape ropes
had deteriorated over time, and the load
capability was considerably reduced. We are
issuing this AD to ensure that flightcrew
members safely reach the ground after exiting
the flight compartment window during an
emergency evacuation.
We have 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 that the 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. See the ADDRESSES section
for a location to examine the regulatory
evaluation.

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 Fokker Model F27 Mark 050 and Model F.28
Mark 0070 and 0100 airplanes with escape rope assemblies in the flight
compartment. The CAA-NL advises that some operators reported finding
small cracks in the polyester assembly block in which the cotton escape
rope is stored. To establish the strength of the escape rope in the
flight compartment after subsequent repair of the assembly block, a
tensile test was done which revealed that the ropes had deteriorated
over time, and the load bearing capability was considerably reduced.
Correcting this condition would ensure that the flightcrew safely reach
the ground after exiting the flight compartment window during an
emergency evacuation.
Relevant Service Information
Fokker Services B.V. has issued Fokker Service Bulletin SBF50-25-
059 (for Model F27 Mark 050 airplanes) and Fokker Service Bulletin
SBF100-25-099 (for Model F.28 Mark 0070 and 0100 airplanes), both dated
June 28, 2004. The service bulletins describe procedures for removing
the two existing escape rope assemblies in the flight compartment and
installing new escape rope assemblies. The service bulletins also
specify sending the removed escape ropes to Fokker Services B.V.
Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition. The CAA-NL
mandated the service information and issued Dutch airworthiness
directive 2004-159, dated December 24, 2004, to ensure the continued
airworthiness of these airplanes in the Netherlands.
FAA's Determination and Requirements of the Proposed AD
These airplane models 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 airplanes of this type design that are
certificated for operation in the United States.
Therefore, we are proposing this AD, which would require
accomplishing the actions specified in the service information
described previously, except as discussed under ``Differences Among
Proposed AD, Dutch Airworthiness Directive, and Service Information.''
Differences Among Proposed AD, Dutch Airworthiness Directive, and
Service Information
The Dutch airworthiness directive requires amending the airplane
maintenance schedule within one year after the effective date of the
Dutch airworthiness directive to include a new discard task for the
escape ropes after 6 years time-in-service. However, this proposed AD
does not mandate a change to the maintenance schedule, but would
instead require repeating the removal of the existing escape rope
assemblies and installation of new escape rope assemblies every 72
months. These actions are essentially the same as the discard task
(which would include replacement after discarding the escape ropes)
required by the Dutch airworthiness directive.
Although the Accomplishment Instructions of the referenced service
bulletins describe procedures for sending the escape ropes to Fokker
Service B.V. after removal, this proposed AD would not require those
actions. We do not have the authority to direct operators to return
defective components to the parts manufacturer; we can only require
repair or replacement of defective components that are installed on the
airplane.
Costs of Compliance
This proposed AD would affect about 2 airplanes of U.S. registry.
The proposed removal and installation would take about 2 work hours per
airplane, at an average labor rate of $80 per work hour. Required parts
would cost between $387 and $425 per airplane, depending on airplane
configuration. Based on these figures, the estimated cost of the
proposed AD for U.S. operators is between $1,094 and $1,170, or between
$547 and $585 per airplane, per removal and installation.
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.
[[Page 37512]]
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 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 that the 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. See the
ADDRESSES section for a location to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, 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. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
Fokker Services B.V.: Docket No. FAA-2006-25219; Directorate
Identifier 2005-NM-259-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by July 31,
2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Fokker Model F27 Mark 050 and Model F.28
Mark 0070 and 0100 airplanes, certificated in any category; with
escape rope assemblies in the flight compartment.
Unsafe Condition
(d) This AD results from reports of findings of small cracks in
the polyester assembly block in which the cotton escape rope is
stored. A test revealed that the escape ropes had deteriorated over
time, and the load capability was considerably reduced. We are
issuing this AD to ensure that flightcrew members safely reach the
ground after exiting the flight compartment window during an
emergency evacuation.
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.
Replacement
(f) Within 12 months after the effective date of this AD: Remove
the two existing escape rope assemblies in the flight compartment
and install new escape rope assemblies in accordance with the
Accomplishment Instructions of Fokker Service Bulletin SBF50-25-59
(for Model F27 Mark 050 airplanes); and Fokker Service Bulletin
SBF100-25-099 (for Model F.28 Mark 0070 and 0100 airplanes); both
dated June 28, 2004. Repeat the removal and installation thereafter
at intervals not to exceed 72 months.
Alternative Methods of Compliance (AMOCs)
(g)(1) The Manager, International Branch, ANM-116, 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) Before using any AMOC approved in accordance with Sec.
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
Related Information
(h) Dutch airworthiness directive 2004-159, dated December 24,
2004, also addresses the subject of this AD.
