Airworthiness Directives; Agusta S.p.A. Model A109E and A119 
Helicopters

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for Agusta 
S.p.A. (Agusta) Model A109E and A119 helicopters. This AD results from 
mandatory continuing airworthiness information (MCAI) issued by an 
aviation authority of another country to identify and correct an unsafe 
condition on an aviation product. The European Aviation Safety Agency 
(EASA), the Technical Agent for Italy, with which we have a bilateral 
agreement, states in the MCAI: ``Some cases of interference between the 
hydraulic pipe, P/N 109-0761-65-103, and the tail rotor control

[[Page 40961]]

rod assembly have been detected on Model A109E helicopters * * * The 
interference, if not corrected, could damage the hydraulic pipes and 
lead to the loss of the hydraulic system No. 1 in flight. This AD * * * 
is issued to extend the same mandatory corrective actions to A119 model 
due to its design similarity with A109E.''
    This AD requires actions that are intended to address this unsafe 
condition.

DATES: This AD becomes effective on August 21, 2008.
    The incorporation by reference of certain publications is approved 
by the Director of the Federal Register as of August 21, 2008.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued an NPRM to amend 14 CFR part 39 to include an AD that 
would apply to Agusta Model A109E and A119 helicopters on March 10, 
2008. That NPRM was published in the Federal Register on March 19, 2008 
(73 FR 14733). That NPRM proposed the following:
     Within the next 50 hours time-in-service (TIS) and 
thereafter at intervals not to exceed 100 hours TIS, inspecting for 
interference between the hydraulic lines, part number (P/N) 109-0761-
64-103 and P/N 109-0761-65-103, and the tail rotor control rod 
assembly, P/N 109-0032-01-41, and, if interference is found, replacing 
the hydraulic lines with hydraulic lines, P/N 109-0763-96-101 and P/N 
109-0763-97-101.
     Within 180 days, replacing hydraulic lines, P/N 109-0761-
64-103 and P/N 109-0761-65-103, with hydraulic lines, P/N 109-0763-96-
101 and P/N 109-0763-97-101.
    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 (BT) No. 109EP-73, dated 
December 4, 2006, applicable to Model A109E helicopters, and BT No. 
119-22, dated July 11, 2007, applicable to Model A119 helicopters. 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

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. However, this AD requires 
replacing the hydraulic lines within 180 days, unless previously 
accomplished, instead of replacing the hydraulic lines on the dates 
specified in the MCAI. In making this change, we do not intend to 
differ substantively from the information provided in the MCAI and 
related service information. This difference is highlighted in the 
``Differences Between This AD and the MCAI'' section in the AD.

Costs of Compliance

    We estimate that this AD will affect about 78 helicopters of U.S. 
registry and that it will take about 2 work-hours per helicopter to 
inspect and 16 work-hours per helicopter to replace the hydraulic 
lines. The average labor rate is $80 per work-hour. Required parts will 
cost about $562 per helicopter, assuming these parts are no longer 
under warranty. However, because the service information lists these 
parts as covered under warranty, we have assumed that there is no 
charge for these parts. Therefore, as we do not control warranty 
coverage for affected parties, some parties may incur costs higher than 
estimated here. Based on these figures, we estimate the cost of this AD 
on U.S. operators to be $112,320, or $1,440 per helicopter.

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.
