Model A109A and A109A II Helicopters Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: SUMMARY: This amendment supersedes an existing airworthiness directive (AD) for the specified Agusta S.p.A. (Agusta) model helicopters. This AD results from a revised mandatory continuing airworthiness information (MCAI) issued by an aviation authority to identify and correct an unsafe condition on an aviation product. The aviation authority of Italy, with which we have a bilateral agreement, reports that the previous MCAI should not apply to newly redesigned and improved tail rotor blades. This AD requires the same inspections as the current AD but limits the applicability to only three partnumbered tail rotor blades. This AD requires actions that are intended to prevent fatigue failure of a tail rotor blade (blade), loss of a tail rotor, and subsequent loss of control of the helicopter. This AD becomes effective on December 30, 2008. The incorporation by reference of certain publications is approved by the Director of the Federal Register as of December 30, 2008. ADDRESSES: You may examine the AD docket on the Internet at http:// regulations.gov or in person at the Docket Operations office, U.S. Department of Transportation, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC between 9 a.m. and 5 p.m. Monday through Friday, except Federal holidays.

SUPPLEMENTARY INFORMATION: Discussion We issued an NPRM on July 27, 2008 to amend 14 CFR part 39 to include a superseding AD that would apply to the specified Agusta model helicopters. That NPRM was published in the Federal Register on August 6, 2008 (73 FR 45644) and proposed the same inspection requirements as the current AD. It also proposed to limit the applicability to only three partnumbered tail rotor blades. You may obtain further information by examining the MCAI and any related service information in the AD docket. Comments By publishing the NPRM, we gave the public an opportunity to participate in developing this AD. However, we received no comment on the NPRM or on our determination of the cost to the public. Therefore, based on our review and evaluation of the available data, we have determined that air safety and the public interest require adopting the AD as proposed. Relevant Service Information Agusta has issued Bollettino Tecnico No. 109–110, Revision A, dated December 12, 2005 (BT). The actions described in the MCAI are intended to correct the same unsafe condition as that identified in the service information. Differences Between This AD and the MCAI The MCAI states to comply with the manufacturer’s BT. This AD differs from the incorporated portions of the BT as follows: (1) We refer to the compliance time as hours time-in-service rather than flight hours. (2) We do not require you to contact the manufacturer. Costs of Compliance We estimate that this AD will affect about 40 helicopters of U.S. registry. We also estimate that it will take about 2.5 E:\FR\FM\25NOR1.SGM 25NOR1 Federal Register / Vol. 73, No. 228 / Tuesday, November 25, 2008 / Rules and Regulations work-hours to inspect the affected blades of each helicopter at an average labor rate of $80 per work-hour. The cost of performing the daily magnifying glass visual inspection is negligible. Based on these figures, we estimate the cost of this AD on U.S. operators to be $48,000, assuming 6 dye-penetrant inspections a year, negligible costs for the magnifying glass inspection, and no cracked blades are found. Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: ■ PART 39—AIRWORTHINESS DIRECTIVES erowe on PROD1PC63 with RULES 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. Therefore, 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 an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

Regulatory Findings VerDate Aug<31>2005 Differences Between This AD and the MCAI Adoption of the Amendment 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 product(s) identified in this rulemaking action. 71527 § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: ■ 2008–24–06 Agusta S.p.A. Amendment 39– 15746; Docket No. FAA–2008–0834; Directorate Identifier 2008–SW–78–AD. Effective Date (a) This airworthiness directive (AD) becomes effective on December 30, 2008. Other Affected ADs (b) This AD supersedes AD 99–27–12, Amendment 39–11493, Docket No. 99–SW– 91–AD (65 FR 346, January 5, 2000). Applicability (c) This AD applies to Model A109A and A109A II helicopters, with a tail rotor blade (blade), part number (P/N) 109–0132–02–11, –15, and –121, with 400 or more hours timein-service (TIS), installed, certificated in any category. Reason (d) Based on the Italian mandatory continued airworthiness information (MCAI) AD, this action contains the same requirement as superseded AD 99–27–12 but narrows the applicability from blade, P/N ‘‘109–0132–02–all dash numbers,’’ to specific P/Ns ‘‘109–0132–02–11, –15, and –121.’’ Thus, this action does not apply to blades with any other P/N, including newly designated blade, P/N 109–0132–02–125. The actions specified by this AD are intended to continue the requirements to prevent fatigue failure of a blade, loss of a tail rotor, and subsequent loss of control of the helicopter. Actions and Compliance (e) Required as indicated; unless already done, do the following actions: (1) Before further flight, dye-penetrant inspect each blade for a crack by following the Compliance Instructions, Part I, of Agusta S.p.A. Bollettino Tecnico No. 109–110, Revision A, dated December 12, 2005 (BT). Thereafter, at intervals not to exceed 100 hours TIS, dye-penetrant inspect each blade for a crack by following the Compliance Instructions, Part III, of the BT. If you find a crack, replace the cracked blade with an airworthy blade before further flight. (2) Before the first flight each day, visually inspect each blade for a crack using a 3 to 5 power magnifying glass by following the Compliance Instructions, Part II, of the BT.

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD) for the specified Agusta S.p.A. (Agusta) model helicopters. This 
AD results from a revised mandatory continuing airworthiness 
information (MCAI) issued by an aviation authority to identify and 
correct an unsafe condition on an aviation product. The aviation 
authority of Italy, with which we have a bilateral agreement, reports 
that the previous MCAI should not apply to newly redesigned and

the current AD but limits the applicability to only three part-numbered 
tail rotor blades. This AD requires actions that are intended to 
prevent fatigue failure of a tail rotor blade (blade), loss of a tail 
rotor, and subsequent loss of control of the helicopter.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued an NPRM on July 27, 2008 to amend 14 CFR part 39 to 
include a superseding AD that would apply to the specified Agusta model 
helicopters. That NPRM was published in the Federal Register on August 
6, 2008 (73 FR 45644) and proposed the same inspection requirements as 
the current AD. It also proposed to limit the applicability to only 
three part-numbered tail rotor blades.
    You may obtain further information by examining the MCAI and any 
related service information in the AD docket.

Comments

    By publishing the NPRM, we gave the public an opportunity to 
participate in developing this AD. However, we received no comment on 
the NPRM or on our determination of the cost to the public. Therefore, 
based on our review and evaluation of the available data, we have 
determined that air safety and the public interest require adopting the 
AD as proposed.

Relevant Service Information

    Agusta has issued Bollettino Tecnico No. 109-110, Revision A, dated 
December 12, 2005 (BT). The actions described in the MCAI are intended 
to correct the same unsafe condition as that identified in the service 
information.

Differences Between This AD and the MCAI

    The MCAI states to comply with the manufacturer's BT. This AD 
differs from the incorporated portions of the BT as follows:
    (1) We refer to the compliance time as hours time-in-service rather 
than flight hours.
    (2) We do not require you to contact the manufacturer.

Costs of Compliance

    We estimate that this AD will affect about 40 helicopters of U.S. 
registry. We also estimate that it will take about 2.5

[[Page 71527]]

work-hours to inspect the affected blades of each helicopter at an 
average labor rate of $80 per work-hour. The cost of performing the 
daily magnifying glass visual inspection is negligible. Based on these 
figures, we estimate the cost of this AD on U.S. operators to be 
$48,000, assuming 6 dye-penetrant inspections a year, negligible costs 
for the magnifying glass inspection, and no cracked blades are found.

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 product(s) 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.
    Therefore, 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 an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.

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:

2008-24-06 Agusta S.p.A. Amendment 39-15746; Docket No. FAA-2008-
0834; Directorate Identifier 2008-SW-78-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective on 
December 30, 2008.

Other Affected ADs

    (b) This AD supersedes AD 99-27-12, Amendment 39-11493, Docket 
No. 99-SW-91-AD (65 FR 346, January 5, 2000).

Applicability

    (c) This AD applies to Model A109A and A109A II helicopters, 
with a tail rotor blade (blade), part number (P/N) 109-0132-02-11, -
15, and -121, with 400 or more hours time-in-service (TIS), 
installed, certificated in any category.

Reason

    (d) Based on the Italian mandatory continued airworthiness 
information (MCAI) AD, this action contains the same requirement as 
superseded AD 99-27-12 but narrows the applicability from blade, P/N 
``109-0132-02-all dash numbers,'' to specific P/Ns ``109-0132-02-11, 
-15, and -121.'' Thus, this action does not apply to blades with any 
other P/N, including newly designated blade, P/N 109-0132-02-125. 
The actions specified by this AD are intended to continue the 
requirements to prevent fatigue failure of a blade, loss of a tail 
rotor, and subsequent loss of control of the helicopter.

Actions and Compliance

    (e) Required as indicated; unless already done, do the following 
actions:
    (1) Before further flight, dye-penetrant inspect each blade for 
a crack by following the Compliance Instructions, Part I, of Agusta 
S.p.A. Bollettino Tecnico No. 109-110, Revision A, dated December 
12, 2005 (BT). Thereafter, at intervals not to exceed 100 hours TIS, 
dye-penetrant inspect each blade for a crack by following the 
Compliance Instructions, Part III, of the BT. If you find a crack, 
replace the cracked blade with an airworthy blade before further 
flight.
    (2) Before the first flight each day, visually inspect each 
blade for a crack using a 3 to 5 power magnifying glass by following 
the Compliance Instructions, Part II, of the BT. If you find a 
crack, replace the cracked blade with an airworthy blade before 
further flight.

Differences Between This AD and the MCAI

    (f) The MCAI states to comply with the manufacturer's BT. This 
AD differs from the incorporated portions of the BT as follows:
    (1) We refer to the compliance time as hours TIS rather than 
flight hours.
    (2) We do not require you to contact the manufacturer.

Other Information

    (g) Alternative Methods of Compliance (AMOCs): The Manager, 
Safety Management Group, Rotorcraft 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: Sharon
