Proposed Rules
Federal Register
Vol. 82, No. 54
Wednesday, March 22, 2017
This section of the FEDERAL REGISTER
contains notices to the public of the proposed
issuance of rules and regulations. The
purpose of these notices is to give interested
persons an opportunity to participate in the
rule making prior to the adoption of the final
rules.
DEPARTMENT OF TRANSPORTATION

Airworthiness Directives; Airbus
Airplanes
Federal Aviation
Administration (FAA), DOT.
ACTION: Supplemental notice of
proposed rulemaking (SNPRM);
reopening of comment period.
AGENCY:
We are revising an earlier
proposal to supersede Airworthiness
Directive (AD) 2013–10–03 for all
Airbus Model A330–200, –200
Freighter, and –300 series airplanes; and
Model A340–200, –300, –500, and –600
series airplanes. This action revises the
notice of proposed rulemaking (NPRM)
by adding a replacement of certain main
landing gear (MLG) with MLG that have
an improved bogie beam. We are
proposing this AD to address the unsafe
condition on these products. Since these
actions impose an additional burden
over those proposed in the NPRM, we
are reopening the comment period to
allow the public the chance to comment
on these proposed changes.
DATES: We must receive comments on
this SNPRM by May 8, 2017.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Discussion
On May 13, 2013, we issued AD
2013–10–03, Amendment 39–17456 (78
FR 31386, May 24, 2013) (‘‘AD 2013–
10–03’’). AD 2013–10–03 requires
actions intended to address an unsafe
condition on all Airbus Model A330–
200, –200 Freighter, and –300 series
airplanes; and Model A340–200, –300,
-–500, and –600 series airplanes. (AD
2013–10–03 superseded AD 2010–02–
10, Amendment 39–16181 (75 FR 4477,
January 28, 2010)).
We issued an NPRM to amend 14 CFR
part 39 by adding an AD that would
apply to all Airbus Model A330–200,
–200 Freighter, and –300 series
airplanes; and Model A340–200 and
–300 series airplanes. The NPRM
published in the Federal Register on
March 1, 2016 (81 FR 10540) (‘‘the
NPRM’’). The NPRM was prompted by
reports of corroded and cracked bogie
beams under the bogie stop pad. The
NPRM proposed to remove Model
A340–500 and –600 series airplanes
from the applicability, remove certain
one-time inspections of the MLG bogie
beams and the sliding piston subassembly, revise certain compliance
times, and provide, for certain airplanes,
an optional terminating action for the
repetitive actions.
Actions Since the NPRM Was Issued
Since we issued the NPRM, we have
determined that MLG having part
number (P/N) 201252 series and P/N
201490 series should be replaced with
a MLG that has an improved bogie
beam, which would constitute
terminating action for the repetitive
inspections on the modified MLG.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2016–0108,
dated June 8, 2016 (referred to after this
E:\FR\FM\22MRP1.SGM
22MRP1
Federal Register / Vol. 82, No. 54 / Wednesday, March 22, 2017 / Proposed Rules
jstallworth on DSK7TPTVN1PROD with PROPOSALS
as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Airbus Model A330–200,
–200 Freighter, and –300 series
airplanes; and Model A340–200 and
–300 series airplanes. The MCAI states:
During a scheduled maintenance
inspection on the Main Landing Gear (MLG),
the bogie stop pad was found deformed and
cracked. Upon removal of the bogie stop pad
for replacement, the bogie beam was also
found cracked. The results of a laboratory
investigation indicated that an overload
event had occurred and no fatigue
propagation of the crack was evident. A
second bogie beam crack was subsequently
found on another aeroplane, located under a
bogie stop pad which only had superficial
paint damage.
This condition, if not detected and
corrected, could lead to landing gear bogie
detachment from the aeroplane, or landing
gear collapse, or a runway excursion,
possibly resulting in damage to the aeroplane
and injury to the occupants and/or people on
the ground.
To address this potential unsafe condition,
EASA issued AD 2008–0223 to require
accomplishment of a one-time detailed
inspection under the bogie stop pad of both
MLG bogie beams. As a result of the one-time
inspection required by that [EASA] AD,
numerous bogie stop pad were found
corroded and a few cracked. The one-time
inspection was retained in EASA AD 2011–
0211 [which corresponds to FAA AD 2013–
10–03], which superseded EASA AD 2008–
0223, which also introduced repetitive
inspections, except for A340–500/–600
aeroplanes.
After EASA AD 2011–0211 was issued,
further investigation led to the conclusion
that the one-time inspection was no longer
necessary and only the repetitive inspections
should remain. In addition, it was
determined that repetitive inspections were
also necessary for MLG on A340–500/–600
aeroplanes.
Prompted by these conclusions, EASA
issued AD 2014–0120, partially retaining the
requirements of EASA AD 2011–0211, which
was superseded, and introducing repetitive
detailed inspections of the MLG on A340–
500 and A340–600 aeroplanes. Subsequently,
further analysis indicated that repetitive
inspections of the MLG on A340–500/–600
aeroplanes were not necessary after all. In
addition, the threshold for the inspection of
MLG P/N 10–210 series was raised from 24
to 126 months, and Airbus developed a
modification of the MLG P/N 10–210 series
which provides an (optional) terminating
action for the repetitive inspections.
Consequently, EASA AD 2014–0120 was
revised to delete the requirements for A340–
500/–600 aeroplanes, to amend the
inspection threshold for MLG P/N 10–210
series, and to introduce an optional
terminating action for aeroplanes with MLG
P/N 10–210 series.
Since EASA AD 2014–0120R1 was issued,
Airbus developed a modification (mod
205289) of the MLG P/N 201252 series and
P/N 201490 series that must be embodied in
VerDate Sep<11>2014

Jkt 241001
service with Airbus SB A330–32–3275 or SB
A340–32–4305. It was also identified that
A340–500/–600 aeroplanes could be removed
from the applicability of this [EASA] AD as
no more actions were required on these
aeroplanes.
For the reason described above, this
[EASA] AD retains the requirements of EASA
AD 2014–0120R1, which is superseded,
removes the A340–500/–600 aeroplanes from
the Applicability and requires the
modification of the MLG P/N 201252 series
and P/N 201490 series, which constitutes
terminating action for the repetitive
inspections required by this [EASA] AD.
The required actions include
repetitive detailed inspections for
damage and corrosion of the sliding
piston sub-assembly, and related
investigative and corrective actions if
necessary. Related investigative actions
include a test for indications of
corrosion and damage to the bogie
assembly base material, and a magnetic
particle inspection for cracks, corrosion,
and damage of the bogie beam.
Corrective actions include repairing
affected parts.
The required terminating action (for
MLG having P/N 201252 series or P/N
201490 series) and the optional
terminating action (for MLG having P/N
10–210) are modifications of the bogie
beam of an MLG, which consist of
installing a nickel under chrome
coating, a new bogie beam stop pad, and
new stop pad brackets.

Comments
We gave the public the opportunity to
participate in developing this proposed
AD. We considered the comments
received on the proposal and the FAA’s
response to each comment.
Requests To Revise Applicability and
Terminating Action
Air France (AF) and American
Airlines (AAL) requested that we revise
the applicability of the proposed AD to
exclude airplanes that have had Airbus

Modification 205289 incorporated in
production.
AAL also requested that we exclude
airplanes from the applicability that
have accomplished the actions specified
in Airbus Service Bulletin A330–32–
3268, dated April 20, 2015, which
describes procedures for modification of
the bogie beam of an MLG having P/N
10–210, and Airbus Service Bulletin
A330–32–3275, dated December 23,
2015, which describes procedures for
modification of the bogie beam of an
MLG having P/N 201490.
AAL and AF also requested that we
add Airbus Service Bulletin A330–32–
3275, dated December 23, 2015, as a
terminating action in paragraph (m) of
the proposed AD. AF also asked that we
add Airbus Service Bulletin A340–32–
4305, dated December 23, 2015, as a
terminating action in paragraph (m) of
the proposed AD. AF and AAL
referenced the applicability in the MCAI
as justification for the requests.
We partially agree with the
commenters’ requests. We have revised
paragraph (c) of this proposed AD to
exclude airplanes that have embodied
Airbus Modification 204421 or Airbus
Modification 205289 in production,
which corresponds with the MCAI.
However, we have not revised
paragraph (c) of this proposed AD to
exclude airplanes on which Airbus
Service Bulletin A330–32–3268, dated
April 20, 2015; or Airbus Service
Bulletin A330–32–3275, dated
December 23, 2015; has been done
because those airplanes are not
excluded from the MCAI.
We have added information to
paragraph (m) of this proposed AD to
specify that accomplishing the actions
specified in Messier-Bugatti-DowtyService Bulletin A33/34–32–305,
including Appendix A, dated April 13,
2015, for MLG having P/N 10–210,
constitutes terminating action for the
repetitive inspections. We also have
added information in paragraph (m) of
this proposed AD to specify that
accomplishing the actions specified in
the service information referenced in
paragraph (k) of this proposed AD
(which includes references to Airbus
Service Bulletin A330–32–3275, dated
December 23, 2015; and Airbus Service
Bulletin A340–32–4305, dated
December 23, 2015) constitutes
terminating action for the repetitive
inspections.
Additional Changes to This SNPRM
We have clarified the affected
airplanes for paragraphs (h)(1) and (h)(3)
of this AD by changing the text ‘‘For
airplanes . . . having an MLG P/N
201252 series and P/N 201490 series’’ to
VerDate Sep<11>2014
14:55 Mar 21, 2017
Jkt 241001
‘‘For airplanes . . . having an MLG P/
N 201252 series or P/N 201490 series’’
(replaced the ‘‘and’’ with an ‘‘or’’).
We have removed the reporting
requirements from this SNPRM. We
have also revised the Costs of
Compliance section of this SNPRM to
reflect the revised proposed
requirements.
FAA’s Determination and Requirements
of This SNPRM
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 these same
type designs.
Certain changes described above
expand the scope of the 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 SNPRM.
Costs of Compliance
We estimate that this proposed AD
affects 89 Model A330–200, –200
Freighter, and –300 series airplanes of
U.S. registry.
We estimate that it would take about
13 work-hours 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 this
proposed AD on U.S. operators to be
$98,345, or $1,105 per product.
Currently, there are no Model A340–
200, or –300 series airplanes on the U.S.
Register. However, if an affected
airplane is imported and placed on the
U.S. Register in the future, it would be
subject to the same per-airplane cost
specified above for the Model A330–
200, -200 Freighter, and –300 series
airplanes.
In addition, we estimate that any
necessary follow-on actions would take
about 24 work-hours and require parts
costing $78, for a cost of $2,118 per
product. We have no way of
determining the number of aircraft that
might need these actions.
According to the manufacturer, all of
the parts costs of the optional
terminating action specified in this
SNPRM may be covered under
warranty, thereby reducing the cost
impact on affected individuals. We do
not control warranty coverage for
PO 00000
Frm 00003

Sfmt 4702
affected individuals. As a result, we
have included all costs in our cost
estimate. We have received no definitive
data that would enable us to provide the
work-hour cost estimates for the
optional terminating action specified in
this proposed AD.
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);
3. Will not affect intrastate aviation in
Alaska; and
4. 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.

result in a damaged bogie beam and
consequent detachment of the beam from the
airplane, collapse of the MLG, or departure
of the airplane from the runway, possibly
resulting in damage to the airplane and
injury to occupants.

Discussion
On May 13, 2013, we issued AD 2013-10-03, Amendment 39-17456 (78 FR
31386, May 24, 2013) (``AD 2013-10-03''). AD 2013-10-03 requires
actions intended to address an unsafe condition on all Airbus Model
A330-200, -200 Freighter, and -300 series airplanes; and Model A340-
200, -300, --500, and -600 series airplanes. (AD 2013-10-03 superseded
AD 2010-02-10, Amendment 39-16181 (75 FR 4477, January 28, 2010)).
We issued an NPRM to amend 14 CFR part 39 by adding an AD that
would apply to all Airbus Model A330-200, -200 Freighter, and -300
series airplanes; and Model A340-200 and -300 series airplanes. The
NPRM published in the Federal Register on March 1, 2016 (81 FR 10540)
(``the NPRM''). The NPRM was prompted by reports of corroded and
cracked bogie beams under the bogie stop pad. The NPRM proposed to
remove Model A340-500 and -600 series airplanes from the applicability,
remove certain one-time inspections of the MLG bogie beams and the
sliding piston sub-assembly, revise certain compliance times, and
provide, for certain airplanes, an optional terminating action for the
repetitive actions.
Actions Since the NPRM Was Issued
Since we issued the NPRM, we have determined that MLG having part
number (P/N) 201252 series and P/N 201490 series should be replaced
with a MLG that has an improved bogie beam, which would constitute
terminating action for the repetitive inspections on the modified MLG.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2016-0108, dated June 8, 2016 (referred to after this
[[Page 14643]]
as the Mandatory Continuing Airworthiness Information, or ``the
MCAI''), to correct an unsafe condition for certain Airbus Model A330-
200, -200 Freighter, and -300 series airplanes; and Model A340-200 and
-300 series airplanes. The MCAI states:
During a scheduled maintenance inspection on the Main Landing
Gear (MLG), the bogie stop pad was found deformed and cracked. Upon
removal of the bogie stop pad for replacement, the bogie beam was
also found cracked. The results of a laboratory investigation
indicated that an overload event had occurred and no fatigue
propagation of the crack was evident. A second bogie beam crack was
subsequently found on another aeroplane, located under a bogie stop
pad which only had superficial paint damage.
This condition, if not detected and corrected, could lead to
landing gear bogie detachment from the aeroplane, or landing gear
collapse, or a runway excursion, possibly resulting in damage to the
aeroplane and injury to the occupants and/or people on the ground.
To address this potential unsafe condition, EASA issued AD 2008-
0223 to require accomplishment of a one-time detailed inspection
under the bogie stop pad of both MLG bogie beams. As a result of the
one-time inspection required by that [EASA] AD, numerous bogie stop
pad were found corroded and a few cracked. The one-time inspection
was retained in EASA AD 2011-0211 [which corresponds to FAA AD 2013-
10-03], which superseded EASA AD 2008-0223, which also introduced
repetitive inspections, except for A340-500/-600 aeroplanes.
After EASA AD 2011-0211 was issued, further investigation led to
the conclusion that the one-time inspection was no longer necessary
and only the repetitive inspections should remain. In addition, it
was determined that repetitive inspections were also necessary for
MLG on A340-500/-600 aeroplanes.
Prompted by these conclusions, EASA issued AD 2014-0120,
partially retaining the requirements of EASA AD 2011-0211, which was
superseded, and introducing repetitive detailed inspections of the
MLG on A340-500 and A340-600 aeroplanes. Subsequently, further
analysis indicated that repetitive inspections of the MLG on A340-
500/-600 aeroplanes were not necessary after all. In addition, the
threshold for the inspection of MLG P/N 10-210 series was raised
from 24 to 126 months, and Airbus developed a modification of the
MLG P/N 10-210 series which provides an (optional) terminating
action for the repetitive inspections.
Consequently, EASA AD 2014-0120 was revised to delete the
requirements for A340-500/-600 aeroplanes, to amend the inspection
threshold for MLG P/N 10-210 series, and to introduce an optional
terminating action for aeroplanes with MLG P/N 10-210 series.
Since EASA AD 2014-0120R1 was issued, Airbus developed a
modification (mod 205289) of the MLG P/N 201252 series and P/N
201490 series that must be embodied in service with Airbus SB A330-
32-3275 or SB A340-32-4305. It was also identified that A340-500/-
600 aeroplanes could be removed from the applicability of this
[EASA] AD as no more actions were required on these aeroplanes.
For the reason described above, this [EASA] AD retains the
requirements of EASA AD 2014-0120R1, which is superseded, removes
the A340-500/-600 aeroplanes from the Applicability and requires the
modification of the MLG P/N 201252 series and P/N 201490 series,
which constitutes terminating action for the repetitive inspections
required by this [EASA] AD.
The required actions include repetitive detailed inspections for
damage and corrosion of the sliding piston sub-assembly, and related
investigative and corrective actions if necessary. Related
investigative actions include a test for indications of corrosion and
damage to the bogie assembly base material, and a magnetic particle
inspection for cracks, corrosion, and damage of the bogie beam.
Corrective actions include repairing affected parts.
The required terminating action (for MLG having P/N 201252 series
or P/N 201490 series) and the optional terminating action (for MLG
having P/N 10-210) are modifications of the bogie beam of an MLG, which
consist of installing a nickel under chrome coating, a new bogie beam
stop pad, and new stop pad brackets.

Comments
We gave the public the opportunity to participate in developing
this proposed AD. We considered the comments received on the proposal
and the FAA's response to each comment.
Requests To Revise Applicability and Terminating Action
Air France (AF) and American Airlines (AAL) requested that we
revise the applicability of the proposed AD to exclude airplanes that
have had Airbus Modification 204421 or Airbus
[[Page 14644]]
Modification 205289 incorporated in production.
AAL also requested that we exclude airplanes from the applicability
that have accomplished the actions specified in Airbus Service Bulletin
A330-32-3268, dated April 20, 2015, which describes procedures for
modification of the bogie beam of an MLG having P/N 10-210, and Airbus
Service Bulletin A330-32-3275, dated December 23, 2015, which describes
procedures for modification of the bogie beam of an MLG having P/N
201490.
AAL and AF also requested that we add Airbus Service Bulletin A330-
32-3275, dated December 23, 2015, as a terminating action in paragraph
(m) of the proposed AD. AF also asked that we add Airbus Service
Bulletin A340-32-4305, dated December 23, 2015, as a terminating action
in paragraph (m) of the proposed AD. AF and AAL referenced the
applicability in the MCAI as justification for the requests.
We partially agree with the commenters' requests. We have revised
paragraph (c) of this proposed AD to exclude airplanes that have
embodied Airbus Modification 204421 or Airbus Modification 205289 in
production, which corresponds with the MCAI. However, we have not
revised paragraph (c) of this proposed AD to exclude airplanes on which
Airbus Service Bulletin A330-32-3268, dated April 20, 2015; or Airbus
Service Bulletin A330-32-3275, dated December 23, 2015; has been done
because those airplanes are not excluded from the MCAI.
We have added information to paragraph (m) of this proposed AD to
specify that accomplishing the actions specified in Messier-Bugatti-
Dowty-Service Bulletin A33/34-32-305, including Appendix A, dated April
13, 2015, for MLG having P/N 10-210, constitutes terminating action for
the repetitive inspections. We also have added information in paragraph
(m) of this proposed AD to specify that accomplishing the actions
specified in the service information referenced in paragraph (k) of
this proposed AD (which includes references to Airbus Service Bulletin
A330-32-3275, dated December 23, 2015; and Airbus Service Bulletin
A340-32-4305, dated December 23, 2015) constitutes terminating action
for the repetitive inspections.
Additional Changes to This SNPRM
We have clarified the affected airplanes for paragraphs (h)(1) and
(h)(3) of this AD by changing the text ``For airplanes . . . having an
MLG P/N 201252 series and P/N 201490 series'' to ``For airplanes . . .
having an MLG P/N 201252 series or P/N 201490 series'' (replaced the
``and'' with an ``or'').
We have removed the reporting requirements from this SNPRM. We have
also revised the Costs of Compliance section of this SNPRM to reflect
the revised proposed requirements.
FAA's Determination and Requirements of This SNPRM
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 these
same type designs.
Certain changes described above expand the scope of the 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 SNPRM.
Costs of Compliance
We estimate that this proposed AD affects 89 Model A330-200, -200
Freighter, and -300 series airplanes of U.S. registry.
We estimate that it would take about 13 work-hours 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 this proposed AD on U.S. operators to be $98,345, or $1,105
per product.
Currently, there are no Model A340-200, or -300 series airplanes on
the U.S. Register. However, if an affected airplane is imported and
placed on the U.S. Register in the future, it would be subject to the
same per-airplane cost specified above for the Model A330-200, -200
Freighter, and -300 series airplanes.
In addition, we estimate that any necessary follow-on actions would
take about 24 work-hours and require parts costing $78, for a cost of
$2,118 per product. We have no way of determining the number of
aircraft that might need these actions.
According to the manufacturer, all of the parts costs of the
optional terminating action specified in this SNPRM may be covered
under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate. We have received no definitive data that would enable us to
provide the work-hour cost estimates for the optional terminating
action specified in this proposed AD.
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);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, 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:
[[Page 14645]]
PART 39--AIRWORTHINESS DIRECTIVES
