Discussion
EASA, which is the Technical Agent for the Member States of the
European Union, has issued AD No. 2017-0025, dated February 14, 2017,
to correct an unsafe condition for Leonardo S.p.A. (formerly
Finmeccanica S.p.A, AgustaWestland S.p.A.) Model AW109SP helicopters.
EASA advises that a hoist cable became snagged behind a hoist handle
assembly nut and broke during a dummy load application. EASA further
advises that this condition could result in detachment of an external
load, and subsequent personal injury or injury to persons on the
ground. To address this unsafe condition, the EASA AD requires
inspecting the hoist cable, modifying the rescue hoist handle, and
amending the rescue hoist pre-flight inspection described in the
rotorcraft flight manual.
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 helicopters of the same type design.
Related Service Information Under 1 CFR Part 51
We reviewed Leonardo Helicopters Bollettino Tecnico No. 109SP-110,
dated February 13, 2017 (BT 109SP-110), which contains procedures for
inspecting the hoist handle, the passenger-side cabin doorframe, and
the hoist cable. This service information also specifies replacing the
attaching hardware on the rescue hoist handle and adding a temporary
pre-flight check of the hoist cable to the Rotorcraft Flight Manual.
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.
[[Page 42231]]
Proposed AD Requirements
This proposed AD would require, within 10 hours time-in-service
(TIS) or before the next hoist operation, whichever occurs first,
inspecting the hoist handle assembly and the upper section of the cabin
doorframe for chafing caused by the hoist cable. If there is any
chafing, this proposed AD would require, before further flight,
repairing the damage and inspecting the first 6 meters (20 feet) of the
hoist cable for cable diameter, broken wires, kinks, bird caging,
flattened areas, abrasion, and necking. If the cable dimension is less
than 4.70 mm (0.185 inch), or if there are any broken wires, kinks,
bird caging, flattened areas, abrasion, or necking, this proposed AD
would require, before the next hoist operation, replacing the hoist
cable.
This proposed AD would also require, within 25 hours TIS, replacing
the rescue hoist handle attaching hardware.
Differences Between This Proposed AD and the EASA AD
The EASA AD requires amending the rotorcraft flight manual by
adding a daily rescue hoist cable preflight inspection, this proposed
AD does not since the actions in this proposed AD would correct the
unsafe condition.
Costs of Compliance
We estimate that this proposed AD would affect 30 helicopters of
U.S. Registry.
At an average labor rate of $85 per hour, we estimate that
operators may incur the following costs in order to comply with this
AD. Inspecting the hoist handle assembly, cabin doorframe, and hoist
cable would require about 2 hours, for a cost of $170 per helicopter
and $5,100 for the U.S. fleet. Replacing the hardware on the hoist
handle assembly would require about 1 hour and required parts cost
would be minimal, for a cost of $85 per helicopter and $2,550 for the
U.S. fleet.
If required, replacing a hoist cable would require about 3 hours
and required parts would cost $3,150, for a cost per helicopter of
$3,405.
According to Leonardo Helicopter's service information some of the
costs of this proposed AD may be covered under warranty, thereby
reducing the cost impact on affected individuals. We do not control
warranty coverage by Leonardo Helicopters. Accordingly, we have
included all costs in our cost estimate.
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
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 airworthiness
directive (AD):
Leonardo S.p.A. (Type Certificate Previously Held by Finmeccanica
S.p.A, AgustaWestland S.p.A): Docket No. FAA-2018-0726; Product
Identifier 2017-SW-097-AD.
(a) Applicability
This AD applies to Model AW109SP helicopters, certificated in
any category, with a rescue hoist part number 109-B810-16-101 or
109-B810-16-201 installed.
(b) Unsafe Condition
This AD defines the unsafe condition as chafing of a rescue
hoist cable. This condition could result in detachment of an
external load and subsequent injury to persons being lifted.
(c) Comments Due Date
We must receive comments by October 22, 2018.
(d) Compliance
You are responsible for performing each action required by this
AD within the specified compliance time unless it has already been
accomplished prior to that time.
(e) Required Actions
(1) Within 10 hours time-in-service (TIS) or before the next
hoist operation, whichever occurs first, inspect the rescue hoist
handle assembly and the upper part of the cabin doorframe for
chafing. The inspection area of the cabin doorframe is depicted in
Figure 3 of Leonardo Helicopters Bollettino Tecnico No. 109SP-110,
dated February 13, 2017 (BT 109SP-110). Examples of chafing are
shown in Figures 10 and 11 of BT 109SP-110. If there is any chafing,
before further flight, repair the chafed areas and inspect the first
6 meters (20 feet) of the hoist cable as follows:
(i) Measure the diameter of the hoist cable as described in the
Compliance Instructions, Part I, paragraphs 3.4.1 through 3.4.2 of
BT 109SP-110.
(ii) Average the two measurements at each location. If at any
location the diameter of the hoist cable is less than 4.7 mm (0.185
inch), before the next hoist operation, remove the hoist cable from
service.
(iii) Inspect the hoist cable for broken wires, kinks, bird
caging, flattened areas, abrasion, and necking, referencing the
examples shown and depicted in Figures 5 through 9 of BT 109SP-110.
If there are any broken wires, kinks, bird caging, flattened areas,
abrasion, or necking, before the next hoist operation, remove the
hoist cable from service.
(2) Within 25 hours TIS, replace the rescue hoist handle
attaching hardware as described in the Compliance Instructions, Part
II, paragraphs 3 through 6, of BT 109SP-110.
(f) Special Flight Permits
A one-time special flight permit may be granted provided that
the hoist is not used.

notify your principal inspector, or lacking a principal inspector,
the manager of the local flight standards district office or
certificate holding district office before operating any aircraft
complying with this AD through an AMOC.
