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 June 9, 2009 (74 FR 27260).
That NPRM proposed to correct an
unsafe condition for the specified
products. The MCAI states:
Following a red illuminated ‘‘DOOR NOT
LOCKED’’ status light indication on the door
lock indication panel after lift off, the cabin
crew operated the door lock handle. This
resulted in inadvertent opening of the
downward opening passenger door in flight.
It appeared that the cabin crew was unaware
of the content of Fokker 70/100 Service Letter
(SL) 272. This SL informs not to operate the
door lock handle after the aircraft has started
to move or before it has come to a complete
standstill.
After inspection, it was found that the false
red light might be the result of an incorrect
clearance between lever Part Number (P/N)
A26997–003 and the Up-Limit Switch. If the
Up-Limit Switch has an incorrect clearance,
the combination with cabin differential
pressure build-up after lift-off might result in
a false steady illuminating red ‘‘DOOR NOT
PO 00000
Frm 00032
Fmt 4700
Sfmt 4700
LOCKED’’ indication on the Door Indication
Panel. The original Fokker Service Bulletin
SBF100–52–044 and the associated Aircraft
Maintenance Manual (AMM) task mentioned
a clearance of 1,3 mm ± 0,3 mm. Later, based
on a trial, an improved clearance of 0,3 mm
± 0,2 mm was introduced. Both documents
have been revised for that reason. Later
production serial number aircraft with
downward opening passenger doors had the
correct clearance introduced before delivery,
but no action was taken to inspect and adjust
the clearance on previously delivered or
modified (per SBF100–52–044) serial
numbers.
Since an unsafe condition has been
identified that is likely to exist or develop on
other aircraft of the same type design, this
[EASA] Airworthiness Directive (AD)
requires two actions:
—The installation of a warning placard near
the status lights of the door lock indication
panel, instructing the cabin crew not to
operate the door handle during flight and
to inform the flight crew of the ‘‘DOOR
NOT LOCKED’’ indication; and
—A one-time inspection of the clearance
between lever P/N A26997–003 and the
Up-Limit Switch. If this clearance deviates
from the limits given in AMM task 52–71–
01–400–814–A, which is 0,3 mm ± 0,2 mm
(0.0118 inch ± 0.0079 inch), corrective
actions are required.
The unsafe condition is inadvertent
opening of the door lock handle in
flight, which could result in rapid
decompression of the airplane or
ejection of a passenger or crewmember
through the door. The corrective action
for improper clearance is adjusting the
clearance between the lever and the uplimit switch. 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.
E:\FR\FM\09SER1.SGM
09SER1
Federal Register / Vol. 74, No. 173 / Wednesday, September 9, 2009 / Rules and Regulations
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
10 products of U.S. registry. We also
estimate that it will take about 4 workhours 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 $20 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 parts. 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 this AD
to the U.S. operators to be $3,400, or
$340 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
VerDate Nov<24>2008
16:13 Sep 08, 2009
Jkt 217001
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.

‘‘Following a red illuminated ‘‘DOOR NOT
LOCKED’’ status light indication on the door
lock indication panel after lift off, the cabin
crew operated the door lock handle. This
resulted in inadvertent opening of the
downward opening passenger door in flight.
It appeared that the cabin crew was unaware
of the content of Fokker 70/100 Service Letter
(SL) 272. This SL informs not to operate the
door lock handle after the aircraft has started
to move or before it has come to a complete
standstill.
‘‘After inspection, it was found that the
false red light might be the result of an
incorrect clearance between lever Part
Number (P/N) A26997–003 and the Up-Limit
Switch. If the Up-Limit Switch has an
incorrect clearance, the combination with
cabin differential pressure build-up after liftoff might result in a false steady illuminating
red ‘‘DOOR NOT LOCKED’’ indication on the
Door Indication Panel. The original Fokker
Service Bulletin SBF100–52–044 and the
associated Aircraft Maintenance Manual
(AMM) task mentioned a clearance of 1,3 mm
± 0,3 mm. Later, based on a trial, an
improved clearance of 0,3 mm ± 0,2 mm was
introduced. Both documents have been
revised for that reason. Later production
serial number aircraft with downward
opening passenger doors had the correct
clearance introduced before delivery, but no
action was taken to inspect and adjust the
clearance on previously delivered or
modified (per SBF100–52–044) serial
numbers.
‘‘Since an unsafe condition has been

01–400–814–A, which is 0,3 mm ± 0,2 mm
(0.0118 inch ± 0.0079 inch), corrective
actions are required.’’
The unsafe condition is inadvertent
opening of the door lock handle in flight,
which could result in rapid decompression of
the airplane or ejection of a passenger or
crewmember through the door. The
corrective action for improper clearance is
adjusting the clearance between the lever and
the up-limit switch.
Actions and Compliance
(f) Unless already done, do the following
actions:
(1) Within 500 flight cycles or 4 months
after the effective date of this AD, whichever
occurs first, install a new warning placard
near the status lights of the panel of the door
lock indication, in accordance with the
Accomplishment Instructions of Fokker

November 1, 2007.
(4) If done before the effective date of this
AD, installing the warning placard near the
status lights of the panel of the door lock
indication, in accordance with Fokker
Service Bulletin SBF100–11–025, dated
November 1, 2007, is acceptable for
compliance with the requirements of
paragraph (f)(1) of this AD.
(5) Modifying the airplane in accordance
with Fokker Service Bulletin SBF100–52–

terminates the requirements of paragraph
(f)(2) of this AD.
FAA AD Differences
jlentini on DSKJ8SOYB1PROD with RULES
Note 1: This AD differs from the MCAI
and/or service information as follows:
Note 1 of the ‘‘Compliance’’ section of
European Aviation Safety Agency (EASA)
Airworthiness Directive 2008–0020, dated
January 28, 2008, states that any airplane that
has not yet been modified in accordance with
Fokker Service Bulletin SBF100–52–069,
dated December 3, 2001, must be modified
prior to or concurrently with paragraph (f)(1)
of this AD. However, all U.S. airplanes have
met this requirement with the issuance of AD
2006–03–07, amendment 39–14471;
therefore, modification in accordance with
Fokker Service Bulletin SBF100–52–069,
dated December 3, 2001, is not applicable.
Other FAA AD Provisions
(g) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, International
Branch, ANM–116, Transport Airplane
Directorate, FAA, has the authority to
approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19.

any approved AMOC on any airplane to
which the AMOC applies, notify your
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 FAAapproved 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.

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:
A recent event occurred during which the
LH [left-hand] forward side glass window of
an ATR 72–212 aeroplane blew out while
performing a ground pressure test.
The investigation revealed some anomalies
on the forward side window at the level of
the Z-bar on the windows external side and
at the level of the inner retainer on the
windows internal side. These anomalies are
considered as precursors of this failure.
*
*
*
*
*
An in-flight loss of a forward side window
could have catastrophic consequences for the
aeroplane and/or cause injuries to people on
the ground. The loss of the forward side
window while the aeroplane is on the ground
with a positive differential cabin pressure
could also cause injuries to people inside or
around the aeroplane.

This AD requires actions that are
intended to address the unsafe
condition described in the MCAI.

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 June 9, 2009 (74 FR
27260). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Following a red illuminated ``DOOR NOT LOCKED'' status light
indication on the door lock indication panel after lift off, the
cabin crew operated the door lock handle. This resulted in
inadvertent opening of the downward opening passenger door in
flight. It appeared that the cabin crew was unaware of the content
of Fokker 70/100 Service Letter (SL) 272. This SL informs not to
operate the door lock handle after the aircraft has started to move
or before it has come to a complete standstill.
After inspection, it was found that the false red light might be
the result of an incorrect clearance between lever Part Number (P/N)
A26997-003 and the Up-Limit Switch. If the Up-Limit Switch has an
incorrect clearance, the combination with cabin differential
pressure build-up after lift-off might result in a false steady
illuminating red ``DOOR NOT LOCKED'' indication on the Door
Indication Panel. The original Fokker Service Bulletin SBF100-52-044
and the associated Aircraft Maintenance Manual (AMM) task mentioned
a clearance of 1,3 mm 0,3 mm. Later, based on a trial,
an improved clearance of 0,3 mm 0,2 mm was introduced.
Both documents have been revised for that reason. Later production
serial number aircraft with downward opening passenger doors had the
correct clearance introduced before delivery, but no action was
taken to inspect and adjust the clearance on previously delivered or
modified (per SBF100-52-044) serial numbers.
Since an unsafe condition has been identified that is likely to
exist or develop on other aircraft of the same type design, this
[EASA] Airworthiness Directive (AD) requires two actions:
--The installation of a warning placard near the status lights of
the door lock indication panel, instructing the cabin crew not to
operate the door handle during flight and to inform the flight crew
of the ``DOOR NOT LOCKED'' indication; and
--A one-time inspection of the clearance between lever P/N A26997-
003 and the Up-Limit Switch. If this clearance deviates from the
limits given in AMM task 52-71-01-400-814-A, which is 0,3 mm 0,2 mm (0.0118 inch 0.0079 inch), corrective
actions are required.
The unsafe condition is inadvertent opening of the door lock handle in
flight, which could result in rapid decompression of the airplane or
ejection of a passenger or crewmember through the door. The corrective
action for improper clearance is adjusting the clearance between the
lever and the up-limit switch. 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.
[[Page 46335]]
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 10 products of U.S. registry.
We also estimate that it will take about 4 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 $20 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 parts. 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 this AD to the U.S. operators
to be $3,400, or $340 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.

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 adding the following new AD:
2009-18-11 Fokker Services B.V.: Amendment 39-16007. Docket No. FAA-
2009-0515; Directorate Identifier 2008-NM-071-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective October
14, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Fokker Model F.28 Mark 0070 and 0100
series airplanes, certificated in any category, equipped with a
downward-opening ``airstair'' type passenger door.
Subject
(d) Air Transport Association (ATA) of America Codes 11 and 52:
Placards and Markings, and Doors, respectively.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
``Following a red illuminated ``DOOR NOT LOCKED'' status light
indication on the door lock indication panel after lift off, the
cabin crew operated the door lock handle. This resulted in
inadvertent opening of the downward opening passenger door in
flight. It appeared that the cabin crew was unaware of the content
of Fokker 70/100 Service Letter (SL) 272. This SL informs not to
operate the door lock handle after the aircraft has started to move
or before it has come to a complete standstill.
``After inspection, it was found that the false red light might
be the result of an incorrect clearance between lever Part Number
(P/N) A26997-003 and the Up-Limit Switch. If the Up-Limit Switch has
an incorrect clearance, the combination with cabin differential
pressure build-up after lift-off might result in a false steady
illuminating red ``DOOR NOT LOCKED'' indication on the Door
Indication Panel. The original Fokker Service Bulletin SBF100-52-044
and the associated Aircraft Maintenance Manual (AMM) task mentioned
a clearance of 1,3 mm 0,3 mm. Later, based on a trial,
an improved clearance of 0,3 mm 0,2 mm was introduced.
Both documents have been revised for that reason. Later production
serial number aircraft with downward opening passenger doors had the
correct clearance introduced before delivery, but no action was
taken to inspect and adjust the clearance on previously delivered or
modified (per SBF100-52-044) serial numbers.
``Since an unsafe condition has been identified that is likely
to exist or develop on other aircraft of the same type design, this
[EASA] Airworthiness Directive (AD) requires two actions:
--The installation of a warning placard near the status lights of
the door lock indication panel, instructing the cabin crew not to
operate the door handle during flight and to inform the flight crew
of the ``DOOR NOT LOCKED'' indication; and
--A one-time inspection of the clearance between lever P/N A26997-
003 and the Up-Limit Switch. If this clearance deviates from the
limits given in AMM task 52-71-01-400-814-A, which is 0,3 mm 0,2 mm (0.0118 inch 0.0079 inch), corrective
actions are required.''
The unsafe condition is inadvertent opening of the door lock
handle in flight, which could result in rapid decompression of the
airplane or ejection of a passenger or crewmember through the door.
The corrective action for improper clearance is adjusting the
clearance between the lever and the up-limit switch.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Within 500 flight cycles or 4 months after the effective
date of this AD, whichever occurs first, install a new warning
placard near the status lights of the panel of the door lock
indication, in accordance with the Accomplishment Instructions of
Fokker Service Bulletin SBF100-11-025, Revision 1, dated December
13, 2007.
(2) Within 4,000 flight cycles after the effective date of this
AD, do a one-time
[[Page 46336]]
inspection of the clearance between lever P/N A26997-003 and the up-
limit switch, in accordance with the Accomplishment Instructions of
Fokker Service Bulletin SBF100-52-086, dated November 1, 2007.
(3) If any clearance is found outside the range defined in
Fokker Service Bulletin SBF100-52-086, dated November 1, 2007,
during the inspection required by paragraph (f)(2) of this AD,
before further flight, correct the clearance in accordance with the
Accomplishment Instructions of Fokker Service Bulletin SBF100-52-
086, dated November 1, 2007.
(4) If done before the effective date of this AD, installing the
warning placard near the status lights of the panel of the door lock
indication, in accordance with Fokker Service Bulletin SBF100-11-
025, dated November 1, 2007, is acceptable for compliance with the
requirements of paragraph (f)(1) of this AD.
(5) Modifying the airplane in accordance with Fokker Service
Bulletin SBF100-52-044, Revision 1, dated November 1, 2007,
terminates the requirements of paragraph (f)(2) of this AD.
FAA AD Differences
Note 1: This AD differs from the MCAI and/or service
information as follows:
Note 1 of the ``Compliance'' section of European Aviation Safety
Agency (EASA) Airworthiness Directive 2008-0020, dated January 28,
2008, states that any airplane that has not yet been modified in
accordance with Fokker Service Bulletin SBF100-52-069, dated
December 3, 2001, must be modified prior to or concurrently with
paragraph (f)(1) of this AD. However, all U.S. airplanes have met
this requirement with the issuance of AD 2006-03-07, amendment 39-
14471; therefore, modification in accordance with Fokker Service
Bulletin SBF100-52-069, dated December 3, 2001, is not applicable.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, Transport Airplane Directorate, 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 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.
