SUMMARY: We are adopting a new 

airworthiness directjve (AD) for Airbus 

Helicopters Model MBB-BK 117 C- 2 

helicopters with a certain Goodrich 

rescue hoist damper w1it (damper unit) 

installed. This AD requires repairing or 

replacing the Jamper unll or 

deactivating the rescue hoist. This AD is 

prompted by a report of an 

uncommanded detachment of a damper 

unit from the cable. These actions are 

intended to prevent loss of an external 

load or person from the helicopter hoist 

and injmy to persons being lifted by the 

hoist. 

OATES: This AD becomes effective July 

15. 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain document listed in this AD 

as of July 15, 2014. 

We must receive comments o 

AD by August 29, 2014.

Discussion 

EASA, which is the Technical Agent 

for the Member States of the European 

Utcion . has issued AD No. 2014-0057, 

dated March 6, 2014, and corrected 

March 7, 2014 (AD 2014- 0057), to 

correct an unsafe condition for Airbus 

Helicopters Model MBB-BK 117 C-2 

helicopters. EASA advises that a rescue 

hoist damper unit detached from the 

cable when the hoist damper was lifted 

by hand with no load attached. EASA 

further advises that an investigation 

revealed the retaining ring inside the 

damper unit was not located in the 

proper position, and that this 

displacement of tbe retaining ring may 

have occurred as a maintenance error or 

as a result of interference with the 

bonding strap unit during normal use. 

EASA further states that this condition 

could lead to the detachment of an 

external load or person from the 

helicopter hoist, possibly resulting ln 

personal injury or injury to persons on 

the ground. 

To address this unsafe condition, 

EASAissued AD 2014-0057, which 

supersedes AD No. 2014- 0046- E, dated 

February 27, 2014, and whicb requires 

replacing Goodrich rescue hoist damper 

unit/rescue winch damper, part number 

(PIN) 44307-480. PIN 44307-480-1, or 

PIN 44307-480-2, or deactivating the 

rescue hoist. AD 2014- 0057 also 

requires modifying the damper unit's 

bondjng strap and replacing the 

retaining rin , which allows reactivation 

of the e ue oist. Lastly, AD 2014-

i Ierne ts a recurring 100 hoistde · p c of the retain.ing ring for 

ect i s a l ion. 

hese h c pters have been approved 

· ati authority of Germany 

oved for operation in the 

States. Pursuant to our bilateral 

agreement with Germany, EASA, its 

technical representative, has notified us 

of the unsafe condition described in the 

EASA AD. We are issuing this AD 

because we evaluated all information 

pmvided by EASA and determined the 

unsafe condition exists <md is likely to 

exist or develop on other helicopters of 

the same type design. 

Related Service Information 

Airbus Helicopters has issued 

Emergency Alert Service Bulletin No. 

ASB MBB-BK117 ~2-85A-041, 

Revision 2, dated March 4, 2014, which 

describes procedures for modifying the 

boncling strap unit, installing an 

improved retaining ring, and inspecting 

the retaining ring. 

AD Requirements 

This AD requires, before the next 

hoist operation, either repairing the 

hoist damper unit by following 

specified portions of the service 

information, replacing the hoist damper 

unit with a unit that has been repaired 

by following specified portions of the 

service information, or deactivating the 

rescue hoist. 

Differences Between This AD and the 

EASAAD 

The EASA AD requires a 100 hoistcycle repetitive inspection, while this 

AD does not. We plan to publish a 

notice of proposed rulemaking to give 

the public an opportunity to comment 

on those long-term requirements. 

lnterinl Action 

We consider this AD to be an interim 

action. If final action is later identified, 

we might consider further rule making 

then. 
Federal Register I Vol. 79. No. 125 I Mooday, June 30, 2014 I Rules and Regulations 36637 

Costs of Compliance 

We estimate that this AD will affect 

118 helicopters of U.S. Registry. We 

estimate that operators may incur the 

following costs in order to comply with 

this AD. At an average labor rate of $85 

per hour. repairing the hoist damper 

unit will require 5 work-hours. and 

required parts will cost S4. for a cost per 

helicopter of 5429. Replacing the hoist 

damper unit will require 1 work-hour. 

and required parts will cost 58,715. for 

a cost per helicopter of 58,800. 

Deactivating the rescue hoist will 

require .5 work-hour, for a cost per 

helicopter of S43. 

According to Airbus Helicopters' 

service information, some of tbe costs of 

this AD may be covered under warranty, 

thereby reducing the cost in1pact on 

affected individuals. We do not control 

warranty coverage by Airbus 

Helicopters. Accordingly, we have 

included all costs in our cost est' 

FAA's Justification and D te 

of the Effective Date 

Providing an opportun ty 

comments before adoptin thes requ irements would delay 

implementing the safety 

to correct this known un a 

Therefore, we find that t ris to e 

flying public justifies wai g notice 

and comment prior to adopting this rule 

because the requjred corrective actions 

must be done before the next hoist 

operation. 

Since an unsafe conilition exists that 

requires the immediate adoption of this 

AD. we determined that notice and 

opportunity for public comment before 

Issuing this AD are impracticable and 

contrary to the public interest and that 

good cause exists for making this 

amendment effective in less than 30 

days. 

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 Admirustrator. "Subtitle VU: 

Aviation Programs," describes in more 

detai I the scope of the Agency's 

authority. 

We are issuing this rulemaking under 

the authority described in "Subtitle VU, 

Part A, Subpart m, 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 Admirustrator 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.
