We propose to adopt a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB139 and AW139 helicopters. This proposed AD would require visually inspecting certain subfloor frames for a crack. This proposed AD is prompted by reports of cracks on in-service helicopters. The proposed actions are intended to detect or prevent a crack in the subfloor frame, which could result in failure of the pilot and co-pilot pedal support frame and subsequent loss of control of the helicopter.

Airworthiness Directives; Agusta S.p.A. Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Agusta S.p.A. (Agusta) Model AB139 and AW139 helicopters. This proposed

helicopters. The proposed actions are intended to detect or prevent a 
crack in the subfloor frame, which could result in failure of the pilot 
and co-pilot pedal support frame and subsequent loss of control of the 
helicopter.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2014-0048, dated March 4, 2014, 
to correct an unsafe condition for Agusta Model AB139 and AW139 
helicopters with a serial number (S/N) 31005 through 31517 (except S/N 
31007, 31415, 31431, 31491, 31500, 31508, and 31516) and S/N 41001 
through 41356 (except S/N 41355). EASA advises that cracks have been 
reported in the subfloor frame at station (STA) 2105 on in-service 
helicopters. This condition, if not detected and corrected, could lead 
to failure of the pedals supporting the frame, which in turn could lead 
to the pedals being inoperative and subsequent loss of control of the 
helicopter, EASA advises.
    The EASA AD requires repetitive inspections of the subfloor frame 
at STA 2105 for a crack. The EASA AD also requires installation of 
frame reinforcements before further flight if there is a crack or 
within 1,200 flight hours if there is no crack. The EASA AD provides 
that installation of the frame reinforcements constitutes terminating 
action for the repetitive inspections required by the AD.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Italy and are approved for operation in the United States. Pursuant to 
our bilateral agreement with Italy, EASA, its technical representative, 
has notified us of the unsafe condition described in its AD. We are 
proposing this AD because we evaluated all known relevant information 
and determined that an unsafe condition is likely to exist or develop 
on other products of the same type design.

Related Service Information Under 1 CFR Part 51

    We reviewed AgustaWestland Bolletino Tecnico No. 139-311, Revision 
B, dated June 4, 2014 (BT), for certain serial-numbered Agusta Model

[[Page 32073]]

AB139 and AW139 helicopters. The BT calls for visual inspections of the 
subfloor frames within 30 flight hours or two months, whichever occurs 
first, and thereafter at intervals of 300 flight hours or 6 months, 
whichever comes first, until frame reinforcements are installed to 
prevent future failures. The BT also specifies installing the frame 
reinforcements immediately if a crack is found and within 1,200 flight 
hours if a crack is not found. This service information is reasonably 
available because the interested parties have access to it through 
their normal course of business or by the means identified in the 
ADDRESSES section of this NPRM.

Proposed AD Requirements

    This proposed AD would require:
     Within 30 hours time-in-service (TIS) and thereafter at 
intervals not to exceed 300 hours TIS, using a light, inspecting all 
visible surfaces of the subfloor frames at station (STA) 2105 for a 
crack.
     If there is a crack, before further flight, and if there 
are no cracks, within 1200 hours TIS, installing frame STA 2105 
retromod part number (P/N) 3G5306P47211. This terminates the repetitive 
inspection requirements of this AD.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires conducting the initial inspection within 30 
flight hours or 2 months, whichever occurs first, and thereafter, at 
intervals not to exceed 300 flight hours or 6 months, whichever occurs 
first. The proposed AD would require conducting the initial inspection 
within 30 TIS, and thereafter, at intervals not to exceed 300 hours 
TIS.

Costs of Compliance

    We estimate that this proposed AD would affect 102 U.S.-registered 
helicopters and that labor costs average $85 a work hour. Based on 
these estimates, we expect the following costs:
     The visual inspection would require 2 work-hours for a 
labor cost of $170 per helicopter. No parts would be needed, so the 
cost would total $170 per helicopter, $17,340 for the U.S. fleet.
     If there are no cracks, installing the frame 
reinforcements would require 240 work-hours for a labor cost of $20,400 
and parts would cost $2,274. The total cost would be $22,674 per 
helicopter.
     If there is a crack, installing the frame reinforcements 
would require 240 work-hours for a labor cost of $20,400 and parts 
would cost $3,401. The total cost would be $23,801 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 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, 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 to the extent that 
it justifies making a regulatory distinction; 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

intervals not to exceed 300 hours TIS, using a light, inspect all 
visible surfaces of the left hand subfloor frame, right hand 
subfloor frame, and middle subfloor frame at station (STA) 2105 for 
a crack as shown in Figures 10 through 13 of AgustaWestland 
Bollettino Tecnico No. 139-311, Revision B, dated June 4, 2014 (BT 
139-311).
    (2) If there is a crack, before further flight, install frame 
STA 2105 retromod part number (P/N) 3G5306P47211 by following the

    (4) Installing frame STA 2105 retromod P/N 3G5306P47211 
terminates the repetitive inspection requirements in paragraph 
(e)(1) of this AD.

(f) Special Flight Permit

    Special Flight Permits are prohibited.

(g) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Safety Management Group, FAA, may approve AMOCs
