condition, if not addressed, could result in difficulty controlling the helicopter.
Accordingly, Canadian AD CF2017
37 requires modification of the lanyard attachment location for certain litter kit installations. Canadian AD CF201737
also specifies that installation of an affected part number litter kit is prohibited unless the installation conforms to the requirements of Airbus Helicopters Service Bulletin SBAHCA
128, Revision 0, dated March 24, 2017.
FAAs Determination These helicopters have been approved by the aviation authority of Canada and are approved for operation in the United States. Pursuant to the FAAs bilateral agreement with Canada, Transport Canada, its technical representative, has notified the FAA of the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of these same type designs.

Related Service Information Under 1
CFR Part 51
The FAA reviewed Airbus Helicopters Service Bulletin SBAHCA128, Revision 0, dated March 24, 2017. This service information specifies procedures for modifying the bead chain tether attachment locations for litter kits with certain part numbers. The modification includes relocating the bead chain tethers by removing the screws and washers for the pip pins on the forward bracket assembly; filling the empty holes with rivets; determining the new locations of and drilling new holes; and securing the bead chain tethers on the top side of the forward bracket assembly in the new hole locations.
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.

described, except as discussed under Differences Between this Proposed AD
and the Transport Canada AD.

Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified in the service information already
The FAA estimates that this AD, if adopted as proposed, would affect 967
helicopters of U.S. Registry. The FAA
estimates the following costs to comply with this proposed AD.

Differences Between This Proposed AD
and the Transport Canada AD
This proposed AD would require a pre-flight check prior to each flight to determine if there is interference between the lanyards that hold the quick release pins to the forward bracket assembly of the litter kit and the flight controls. This pre-flight check requirement would be terminated upon completion of the modification of the litter kit installation. Canadian AD CF
201737 does not include a requirement for the pre-flight check prior to each flight to determine if there is interference between the lanyards and the flight controls.

Authority for This Rulemaking Title 49 of the United States Code specifies the FAAs 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 Agencys authority.
The FAA is 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.

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 Would not affect intrastate aviation in Alaska, and 3 Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Regulatory Findings The FAA determined that this proposed AD would not have federalism
