Airworthiness Directives; AgustaWestland S.p.A. Helicopters
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).

Discussion
EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2016-0216, dated October 28, 2016, to correct an unsafe condition for Leonardo Helicopters (previously Finmeccanica S.p.A., previously AgustaWestland) Model AW189 helicopters, serial numbers 49007 through 49021, 49023, 49029, 49033, 49035, 89001, 89003, 89004, 92001, 92003, and 92005. The EASA AD does not apply to windows that have been reinstalled at least once since helicopter delivery and windows that are part of bubble window kit part number (P/N) 8G5620F00111.
EASA advises that during a scheduled replacement of emergency exit window seals on helicopters in service, an excessively high level of pushing force was required to jettison some of the windows. According to EASA, further investigation determined the windows were installed with glue applied in locations that were not in accordance with the approved design.
This condition, if not corrected, could prevent the jettisoning of helicopter emergency exit windows, possibly affecting the evacuation of crew and passengers during an emergency situation, EASA advises. EASA consequently requires replacement of the seal and the filler wedges of the
Page 50848
emergency exit windows installed in the cockpit doors and cabin.
The FAA is in the process of updating AgustaWestland's name change to Leonardo Helicopters on its type certificate. Because this name change is not yet effective, this proposed AD specifies AgustaWestland.
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
We reviewed Leonardo Helicopters Bollettino Tecnico No. 189-118, dated October 20, 2016. This service information specifies replacing the seal and filler wedges on all cockpit door and cabin emergency exit windows of Model AW189 helicopters, except on those windows that have been replaced or that are part of bubble window kit P/N 8G5620F00111.
Proposed AD Requirements
This proposed AD would require within 75 hours time-in-service, replacing the seal and filler wedges on all emergency exit windows installed in the cockpit doors and cabin.
Costs of Compliance
We estimate that this proposed AD would affect 2 helicopters of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we expect that removing and replacing the window seals and fillers would require 40 work-hours and parts would cost about $834, for a total cost of $4,234 per helicopter and $8,468 for the U.S. fleet.
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:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
-
Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and
-
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.
