Download as PDF 43878 Federal Register / Vol. 75, No. 143 / Tuesday, July 27, 2010 / Proposed Rules Applicability (c) This AD applies to Fokker Services B.V. 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: Two reports have been received where, during inspection of the vertical stabilizer of F28 Mark 0100 aeroplanes, one of the bolts that connect the horizontal stabilizer control unit actuator with the dog-links was found broken (one on the nut side & one on the head side). In both occasions, the bolt shaft was still present in the connection and therefore the horizontal stabilizer function was not affected. If a single dog-link connection fails, the complete stabilizer load is taken up by the remaining dog-link connection. * * * To address and correct this unsafe condition EASA [European Aviation Safety Agency] issued AD 2007–0287 [corresponding FAA AD 2008–22–14] that required a one-time inspection of the affected bolts, * * * and replacement of failed bolts with serviceable parts. EASA AD 2007–0287 also required the installation of a tie wrap through the lower bolts of the horizontal stabilizer control unit, to keep the bolt in place in the event of a bolt head failure. Recent examination revealed that the bolts failed due to stress corrosion, attributed to excessive bolt torque. Investigation of the recently failed bolts showed that the modification as required by AD 2007–0287 is not adequate. * * * * * Loss of horizontal stabilizer function could result in partial loss of control of the airplane. Compliance (f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Restatement of Requirements of AD 2008– 22–14 jdjones on DSK8KYBLC1PROD with PROPOSALS-1 Actions and Compliance (g) Unless already done, within 6 months after December 26, 2008 (the effective date of AD 2008–22–14), 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. VerDate Mar<15>2010 15:29 Jul 26, 2010 Jkt 220001 New Requirements of This AD: Actions (h) Within 30 months after the effective date of this AD, do the actions specified in paragraphs (h)(1) and (h)(2) of this AD concurrently. Accomplishing the actions of both paragraphs (h)(1) and (h)(2) of this AD terminates the actions required by paragraph (g) of this AD. (1) Remove the tie-wrap, P/N MS3367–2– 9, from the lower bolts of the horizontal stabilizer control unit, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100–27–092, dated April 27, 2009. (2) Remove the lower bolts, P/N 23233–1, of the horizontal stabilizer control unit and install bolts, P/N 23233–3, in accordance with the Accomplishment Instructions of Goodrich Service Bulletin 23100–27–29, dated November 14, 2008. (i) After accomplishing the requirements of paragraph (h) of this AD, do not install a bolt having P/N 23233–1 or a tie-wrap having P/N MS3367–2–9.

Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2009–0864; Directorate Identifier 2008–NM–202–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, VerDate Mar<15>2010 15:29 Jul 26, 2010 Jkt 220001 economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD based on those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We proposed to amend 14 CFR part 39 with an earlier NPRM for some of the specified products, which was published in the Federal Register on September 21, 2009 (74 FR 48021). That earlier NPRM proposed to require actions intended to address the unsafe condition for the products listed above. Since that NPRM was issued, we have determined that Model FAN JET FALCON SERIES C, D, E, F, and G airplanes are also subject to the identified unsafe condition. We have revised the applicability in this supplemental NPRM to include these airplanes. Comments We have considered the following comments received on the earlier NPRM. Request To Extend Compliance Time for Certain Airplanes Dassault Aviation (Dassault) requests that we extend the compliance times in Table 1 of the earlier NPRM for Model MYSTERE-FALCON 900, FALCON 900EX, Model FALCON 2000, and FALCON 2000EX airplanes from 1,630 flight hours to 1,640 flight hours. Dassault explains that 1,640 flight hours is the correct amount of time for the 1,600-flight-hour B-check interval and +40-flight-hour tolerance indicated in the ‘‘General’’ section of each airplane’s Chapter 5 Maintenance Schedule. Dassault notes that this extended compliance time has been approved by the European Aviation Safety Agency. We agree, for the reasons provided by the commenter. We have revised Table 1 of this supplemental NPRM accordingly. Request To Include Current Maintenance Procedure Dassault requests that we identify the current maintenance procedures in the AD. Dassault explains that later versions of the maintenance procedures have been created since the earlier NPRM was issued. Dassault also suggests that we add the phrase for Table 2 of this PO 00000 Frm 00015 Fmt 4702 Sfmt 4702 43879 AD, ‘‘as may be amended from time to time by Dassault Aviation.’’ We partially agree. For the reasons provided by the commenter, we agree to identify the current maintenance procedures and have revised the Maintenance Procedure column of Table 2 of this supplemental NPRM accordingly. We do not agree to add the phrase, ‘‘as may be amended from time to time by Dassault Aviation,’’ as it contradicts FAA policy. We cannot refer to procedures or documents in our AD that do not yet exist. Operators may request approval to use a later revision of the specified maintenance procedure as an alternative method of compliance with the proposed requirements under the provisions of paragraph (h)(1) of this supplemental NPRM. Explanation of Change Made to This Supplemental NPRM We have revised this supplemental NPRM to identify the legal name of the manufacturer as published in the most recent type certificate data sheet for the affected airplane models. 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 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. Certain changes described above expand the scope of the earlier NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this proposed AD. 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 E:\FR\FM\27JYP1.SGM 27JYP1 43880 Federal Register / Vol. 75, No. 143 / Tuesday, July 27, 2010 / Proposed Rules policies. Any such differences are highlighted in a Note within the proposed AD. Explanation of Change to Costs of Compliance Since issuance of the earlier NPRM, we have increased the labor rate used in the Costs of Compliance from $80 per work-hour to $85 per work-hour. The Costs of Compliance information, below, reflects this increase in the specified hourly labor rate. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 1,082 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $91,970, or $85 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. Applicability (c) This AD applies to the airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of
comment period.

-----------------------------------------------------------------------

SUMMARY: We are revising an earlier NPRM for the products listed above.
This action revises the earlier NPRM by expanding the scope. 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:

During maintenance on one aircraft, it was discovered that the
overpressure capsules were broken on both pressurization valves.
Failure of the pressurization control regulating valve (overpressure
capsule) will affect the aircraft's overpressure protection * * *.
* * * * *
The unsafe condition is overpressurization, which can result in injury
to the occupants and possible structural failure leading to loss of
control of the airplane. The proposed AD would require actions that are
intended to address the unsafe condition described in the MCAI.

Discussion

We proposed to amend 14 CFR part 39 with an earlier NPRM for some
of the specified products, which was published in the Federal Register
on September 21, 2009 (74 FR 48021). That earlier NPRM proposed to
require actions intended to address the unsafe condition for the
products listed above.
Since that NPRM was issued, we have determined that Model FAN JET
FALCON SERIES C, D, E, F, and G airplanes are also subject to the
identified unsafe condition. We have revised the applicability in this
supplemental NPRM to include these airplanes.

Comments

We have considered the following comments received on the earlier
NPRM.

Request To Extend Compliance Time for Certain Airplanes

Dassault Aviation (Dassault) requests that we extend the compliance
times in Table 1 of the earlier NPRM for Model MYSTERE-FALCON 900,
FALCON 900EX, Model FALCON 2000, and FALCON 2000EX airplanes from 1,630
flight hours to 1,640 flight hours. Dassault explains that 1,640 flight
hours is the correct amount of time for the 1,600-flight-hour B-check
interval and +40-flight-hour tolerance indicated in the ``General''
section of each airplane's Chapter 5 Maintenance Schedule. Dassault
notes that this extended compliance time has been approved by the
European Aviation Safety Agency.
We agree, for the reasons provided by the commenter. We have
revised Table 1 of this supplemental NPRM accordingly.

Request To Include Current Maintenance Procedure

Dassault requests that we identify the current maintenance
procedures in the AD. Dassault explains that later versions of the
maintenance procedures have been created since the earlier NPRM was
issued. Dassault also suggests that we add the phrase for Table 2 of
this AD, ``as may be amended from time to time by Dassault Aviation.''
We partially agree. For the reasons provided by the commenter, we
agree to identify the current maintenance procedures and have revised
the Maintenance Procedure column of Table 2 of this supplemental NPRM
accordingly. We do not agree to add the phrase, ``as may be amended
from time to time by Dassault Aviation,'' as it contradicts FAA policy.
We cannot refer to procedures or documents in our AD that do not yet
exist. Operators may request approval to use a later revision of the
specified maintenance procedure as an alternative method of compliance
with the proposed requirements under the provisions of paragraph (h)(1)
of this supplemental NPRM.

Explanation of Change Made to This Supplemental NPRM

We have revised this supplemental NPRM to identify the legal name
of the manufacturer as published in the most recent type certificate
data sheet for the affected airplane models.

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 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.
Certain changes described above expand the scope of the earlier
NPRM. As a result, we have determined that it is necessary to reopen
the comment period to provide additional opportunity for the public to
comment on this proposed AD.

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

[[Page 43880]]

policies. Any such differences are highlighted in a Note within the
proposed AD.

Explanation of Change to Costs of Compliance

Since issuance of the earlier NPRM, we have increased the labor
rate used in the Costs of Compliance from $80 per work-hour to $85 per
work-hour. The Costs of Compliance information, below, reflects this
increase in the specified hourly labor rate.

Costs of Compliance

Based on the service information, we estimate that this proposed AD
would affect about 1,082 products of U.S. registry. We also estimate
that it would take about 1 work-hour per product to comply with the
basic requirements of this proposed AD. The average labor rate is $85
per work-hour. Based on these figures, we estimate the cost of the
proposed AD on U.S. operators to be $91,970, or $85 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.

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 FAA amends Sec. 39.13 by adding the following new AD:

Dassault Aviation: Docket No. FAA-2009-0864; Directorate Identifier
2008-NM-202-AD.

Comments Due Date

(a) We must receive comments by August 23, 2010.

Affected ADs

(b) None.

Applicability

(c) This AD applies to the airplanes identified in paragraphs
(c)(1) and (c)(2) of this AD, certificated in any category.
(1) DASSAULT AVIATION Model Falcon 10 airplanes, Model FAN JET
FALCON, FAN JET FALCON SERIES C, D, E, F, and G airplanes, and Model
MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes; all serial
numbers, equipped with Liebherr or ABG-Semca pressurization outflow
valves.
(2) DASSAULT AVIATION Model MYSTERE-FALCON 200 airplanes, Model
MYSTERE-FALCON 50 and MYSTERE-FALCON 900, and FALCON 900EX
airplanes, and Model FALCON 2000 and FALCON 2000EX airplanes; all
serial numbers.

Subject

(d) Air Transport Association (ATA) of America Code 21: Air
Conditioning.

Reason

(e) The mandatory continuing airworthiness information (MCAI)
states:

``During maintenance on one aircraft, it was discovered that the
overpressure capsules were broken on both pressurization valves.
Failure of the pressurization control regulating valve (overpressure
capsule) will affect the aircraft's overpressure protection * * *''.
* * * * *
The unsafe condition is overpressurization, which can result in
injury to the occupants and possible structural failure leading to
loss of control of the airplane.

Compliance

(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.

Inspection and Replacement

(g) Unless already done, do the following actions
(1) Within 6 months after the effective date of this AD, or
before reaching the applicable time in the ``Inspection Threshold''
column specified in Table 1 of this AD, whichever occurs later, and
thereafter at intervals not to exceed the applicable time in the
``Inspection Interval'' column specified in Table 1 of this AD:
Inspect for overpressure tightness on both regulating valves using a

(2) If any leak is found during any inspection required by
paragraph (g)(1) of this AD, before further flight, replace the
affected valve with a serviceable unit, using a method approved by
either the Manager, International Branch, ANM-116, Transport
Airplane Directorate, FAA; or the EASA (or its delegated agent).

Note 2: Guidance on replacing regulating valves can be found in
the applicable airplane maintenance manual identified in Table 2 of
this AD.

FAA AD Differences

Note 3: This AD differs from the MCAI as follows: Although
paragraph (3) of the compliance section of the MCAI allows flight in
accordance with the master minimum equipment list (MMEL) provisions
after leaks are found, paragraph (g)(2) of this AD requires
replacing affected valves before further flight.

Other FAA AD Provisions

(h) 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

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.
The AMOC approval letter must specifically reference this AD.
(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 (44
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has
approved the information collection requirements and has assigned
OMB Control Number 2120-0056.
