Discussion
On April 3, 1998, we issued AD 98–
08–14, Amendment 39–10463 (63 FR
17676, April 10, 1998), to require
inspecting each diagonal cross-member
VerDate Aug<31>2005
19:27 Dec 02, 2005
Jkt 208001
for cracks and replacing it with an
airworthy diagonal cross-member if any
crack is found. That action was
prompted by several reports of cracks in
diagonal cross-members. The
requirements of that AD are intended to
prevent failure of the diagonal crossmember, which could cause the MGB to
pivot resulting in severe vibrations and
a subsequent forced landing.
Since issuing that AD, we have
determined the Model SA–366G1
helicopter should be added to the
applicability because this model may
contain an affected diagonal crossmember, part number (P/N) 365A38–
3023–22, –23 or –24. Also, we have
determined after further study and
additional reports of failed diagonal
cross-members that more frequent
inspections of the diagonal crossmember are necessary.
The Direction Generale De L’Aviation
Civile (DGAC), the airworthiness
authority for France, notified the FAA
that an unsafe condition may exist on
ECF Model AS–365N, N1, N2, and SA
366 G1 helicopters. The DGAC advises
of the discovery of a crack in a diagonal
cross-member of the ECF Model SA 366
G1 helicopter.
ECF has issued Service Bulletin (SB)
No. 05.00.37, dated May 29, 1997, for
Model AS–365N, N1, and N2
helicopters. The SB specifies a periodic
inspection for a crack or failure of a
central branch of the MGB suspension
strut pre-MOD 0763B80. ECF has also
issued Alert Service Bulletin (ASB) No.
05.25, dated June 19, 2002. The ASB
specifies checking the center portion of
the MGB suspension cross-bar for Model
AS–366G1 helicopters, with a crossbar,
P/N 365A38–3023–22, –23, or –24,
installed. The DGAC classified these
service bulletins as mandatory and
issued ADs 2003–241(A) and 1997–093–
041(A) R2, both dated June 25, 2003, to
ensure the continued airworthiness of
these helicopters in France.
These helicopter models are
manufactured in France and are type
certificated for operation in the United
States under the provisions of 14 CFR
21.29 and the applicable bilateral
agreement. Pursuant to the applicable
bilateral agreement, the DGAC has kept
the FAA informed of the situation
described above. The FAA has
examined the findings of the DGAC,
reviewed all available information, and
determined that AD action is necessary
for products of these type designs that
are certificated for operation in the
United States.
This previously described unsafe
condition is likely to exist or develop on
other helicopters of the same type
designs. Therefore, the proposed AD
PO 00000
Frm 00008
Fmt 4702
Sfmt 4702
would supersede AD 98–08–14 to
require the following:
• For Model SA–365N and SA–365N1
helicopters, before accumulating 15,000
operating cycles; and for Model AS–
365N2 and SA–366G1 helicopters,
before accumulating 11,000 operating
cycles:
• Inspect the diagonal cross-member
for a crack in the area of the center
borehole. Use a borescope with a 90degree drive, a video assembly with
optical fiber illumination, or any other
appropriate device that makes it
possible to visually inspect the center
area of the part.
• Repeat the previous inspections at
intervals not to exceed 250 operating
cycles or 50 hours time-in-service,
whichever occurs first.
• If a crack is found, before further
flight, replace the diagonal crossmember with an airworthy diagonal
cross-member.
We estimate that this proposed AD
would affect 133 helicopters of U.S.
registry, and would:
• Take about 1 work hour to inspect
the diagonal cross-member,
• Take about 10 work hours to
replace the diagonal cross-member, if
necessary, at an average labor rate of $65
per work hour, and
• Cost about $6,600 to replace the
part.
Based on these figures, we estimate
the total cost impact of the proposed AD
on U.S. operators to be $139,990,
assuming 12 inspections per year per
helicopter, and assuming 5 helicopters
require replacing the diagonal crossmember.
Regulatory Findings
We have determined that this
proposed AD would not have federalism
implications under Executive Order
13132. Additionally, 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 draft economic
evaluation of the estimated costs to
comply with this proposed AD. See the
E:\FR\FM\05DEP1.SGM
05DEP1
Federal Register / Vol. 70, No. 232 / Monday, December 5, 2005 / Proposed Rules
DMS to examine the draft economic
evaluation.
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Safety.
The Proposed Amendment
Accordingly, pursuant to the
authority delegated to me by the
Administrator, the Federal Aviation
Administration proposes to amend part
39 of the Federal Aviation Regulations
(14 CFR part 39) as follows:
(a) For Model SA–365N and SA–365N1
helicopters, before accumulating 15,000
operating cycles; and for Model AS–365N2
and SA–366G1 helicopters, before
accumulating 11,000 operating cycles:
(1) Inspect the diagonal cross-member for
a crack in the area of the center borehole. Use
a borescope with a 90-degree drive, a video
assembly with optical fiber illumination, or
any other appropriate device that allows you
to visually inspect the center area of the part.
(2) Repeat the inspection required by
paragraph (a)(1) of this AD at intervals not to
exceed 250 operating cycles or 50 hours timein-service, whichever occurs first.
Note 1: ‘‘Operating cycles’’ are defined in
the Airworthiness Limitations Section of the
Master Servicing Recommendations.
(b) If a crack is found as a result of the
inspections required by this AD, before
further flight, replace the diagonal crossmember with an airworthy diagonal crossmember.
(c) To request a different method of
compliance or a different compliance time
for this AD, follow the procedures in 14 CFR
39.19. Contact the Safety Management Group,
Rotorcraft Directorate, FAA, for information
about previously approved alternative
methods of compliance.
Note 2: The subject of this AD is addressed
in Direction Generale De L’Aviation Civile
(France) AD 1997–093–041(A) R2, dated June
25, 2003, and 2003–241(A), dated June 25,

Discussion
On April 3, 1998, we issued AD 98-08-14, Amendment 39-10463 (63 FR
17676, April 10, 1998), to require inspecting each diagonal cross-
member for cracks and replacing it with an airworthy diagonal cross-
member if any crack is found. That action was prompted by several
reports of cracks in diagonal cross-members. The requirements of that
AD are intended to prevent failure of the diagonal cross-member, which
could cause the MGB to pivot resulting in severe vibrations and a
subsequent forced landing.
Since issuing that AD, we have determined the Model SA-366G1
helicopter should be added to the applicability because this model may
contain an affected diagonal cross-member, part number (P/N) 365A38-
3023-22, -23 or -24. Also, we have determined after further study and
additional reports of failed diagonal cross-members that more frequent
inspections of the diagonal cross-member are necessary.
The Direction Generale De L'Aviation Civile (DGAC), the
airworthiness authority for France, notified the FAA that an unsafe
condition may exist on ECF Model AS-365N, N1, N2, and SA 366 G1
helicopters. The DGAC advises of the discovery of a crack in a diagonal
cross-member of the ECF Model SA 366 G1 helicopter.
ECF has issued Service Bulletin (SB) No. 05.00.37, dated May 29,
1997, for Model AS-365N, N1, and N2 helicopters. The SB specifies a
periodic inspection for a crack or failure of a central branch of the
MGB suspension strut pre-MOD 0763B80. ECF has also issued Alert Service
Bulletin (ASB) No. 05.25, dated June 19, 2002. The ASB specifies
checking the center portion of the MGB suspension cross-bar for Model
AS-366G1 helicopters, with a crossbar, P/N 365A38-3023-22, -23, or -24,
installed. The DGAC classified these service bulletins as mandatory and
issued ADs 2003-241(A) and 1997-093-041(A) R2, both dated June 25,
2003, to ensure the continued airworthiness of these helicopters in
France.
These helicopter models are manufactured in France and are type
certificated for operation in the United States under the provisions of
14 CFR 21.29 and the applicable bilateral agreement. Pursuant to the
applicable bilateral agreement, the DGAC has kept the FAA informed of
the situation described above. The FAA has examined the findings of the
DGAC, reviewed all available information, and determined that AD action
is necessary for products of these type designs that are certificated
for operation in the United States.
This previously described unsafe condition is likely to exist or
develop on other helicopters of the same type designs. Therefore, the
proposed AD would supersede AD 98-08-14 to require the following:
For Model SA-365N and SA-365N1 helicopters, before
accumulating 15,000 operating cycles; and for Model AS-365N2 and SA-
366G1 helicopters, before accumulating 11,000 operating cycles:
Inspect the diagonal cross-member for a crack in the area
of the center borehole. Use a borescope with a 90-degree drive, a video
assembly with optical fiber illumination, or any other appropriate
device that makes it possible to visually inspect the center area of
the part.
Repeat the previous inspections at intervals not to exceed
250 operating cycles or 50 hours time-in-service, whichever occurs
first.
If a crack is found, before further flight, replace the
diagonal cross-member with an airworthy diagonal cross-member.
We estimate that this proposed AD would affect 133 helicopters of
U.S. registry, and would:
Take about 1 work hour to inspect the diagonal cross-
member,
Take about 10 work hours to replace the diagonal cross-
member, if necessary, at an average labor rate of $65 per work hour,
and
Cost about $6,600 to replace the part.
Based on these figures, we estimate the total cost impact of the
proposed AD on U.S. operators to be $139,990, assuming 12 inspections
per year per helicopter, and assuming 5 helicopters require replacing
the diagonal cross-member.
Regulatory Findings
We have determined that this proposed AD would not have federalism
implications under Executive Order 13132. Additionally, 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 draft economic evaluation of the estimated costs to
comply with this proposed AD. See the
[[Page 72411]]
DMS to examine the draft economic evaluation.
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.

The Proposed Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration proposes to amend
part 39 of the Federal Aviation Regulations (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. Section 39.13 is amended by removing Amendment 39-10463 (63 FR
17676, April 10, 1998), and by adding a new airworthiness directive
(AD), to read as follows:
Eurocopter France: Docket No. FAA-2005-23159; Directorate Identifier
2005-SW-10-AD. Supersedes AD 98-08-14, Amendment 39-10463, Docket
No. 97-SW-21-AD.
Applicability: Model SA-365N, SA-365N1, AS-365N2, and SA-366G1
helicopters with a main gearbox (MGB) suspension diagonal cross-
member (diagonal cross-member) part number (P/N) 365A38-3023-20, -
21, -22, -23, or -24 installed, certificated in any category.
Compliance: Required as indicated, unless accomplished
previously.
To prevent failure of the diagonal cross-member, pivoting of the
MGB, severe vibrations, and subsequent forced landing, do the
following:
(a) For Model SA-365N and SA-365N1 helicopters, before
accumulating 15,000 operating cycles; and for Model AS-365N2 and SA-
366G1 helicopters, before accumulating 11,000 operating cycles:
(1) Inspect the diagonal cross-member for a crack in the area of
the center borehole. Use a borescope with a 90-degree drive, a video
assembly with optical fiber illumination, or any other appropriate
device that allows you to visually inspect the center area of the
part.
(2) Repeat the inspection required by paragraph (a)(1) of this
AD at intervals not to exceed 250 operating cycles or 50 hours time-
in-service, whichever occurs first.
Note 1: ``Operating cycles'' are defined in the Airworthiness
Limitations Section of the Master Servicing Recommendations.
(b) If a crack is found as a result of the inspections required
by this AD, before further flight, replace the diagonal cross-member
with an airworthy diagonal cross-member.
(c) To request a different method of compliance or a different
compliance time for this AD, follow the procedures in 14 CFR 39.19.
