ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: This document proposes superseding an existing airworthiness directive (AD) that currently applies to Eurocopter France (ECF) Model SA 365N, N1, and AS 365N2 helicopters. That AD currently requires inspecting the main gearbox (MGB) suspension diagonal cross-member (diagonal cross- PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 To AMM SD3–30 AMM. SD3–60 AMM. SD3–60 SHERPA AMM. SD3–SHERPA AMM. member) for cracks and replacing it with an airworthy part if any crack is found. This action proposes to require more frequent inspections of the diagonal cross-member and adding the Model SA–366G1 helicopters to the applicability. This proposal is prompted by several reports of cracks in the diagonal cross-member. The actions specified by the proposed AD are intended to prevent failure of the diagonal cross-member, pivoting of the MGB, severe vibrations, and a subsequent forced landing.

Comments will be available in the AD docket shortly after the DMS receives them. 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.

Airworthiness Directives; Eurocopter France Model SA-365N, SA-
365N1, AS-365N2, and SA-366G1 Helicopters

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: This document proposes superseding an existing airworthiness 
directive (AD) that currently applies to Eurocopter France (ECF) Model 
SA 365N, N1, and AS 365N2 helicopters. That AD currently requires 
inspecting the main gearbox (MGB) suspension diagonal cross-member 
(diagonal cross-member) for cracks and replacing it with an airworthy 
part if any crack is found. This action proposes to require more 
frequent inspections of the diagonal cross-member and adding the Model 
SA-366G1 helicopters to the applicability. This proposal is prompted by 
several reports of cracks in the diagonal cross-member. The actions 
specified by the proposed AD are intended to prevent failure of the 
diagonal cross-member, pivoting of the MGB, severe vibrations, and a 
subsequent forced landing.

DATES: Comments must be received on or before February 3, 2006.

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

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. 
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, 2003.
