AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for Airbus 

Helicopters Deutschland GmbH (AHD) 

(previously Eurocopter Deutschland 

GmbH) Model MBB–BK 117 A–1, A–3, 

A–4, B–1, B–2, C–1, and C–2 

helicopters. This proposed AD would 

require an initial and recurring 

inspection of the N2 control arm and, 

depending on the outcome of the 

inspection, repairing or replacing the N2 

control arm. This proposed AD is 

prompted by a report of a heavily 

corroded and broken N2 control arm. 

The proposed actions are intended to 

detect corrosion, a crack, or a scratch in 

the N2 control arm, which could lead to 

failure of the N2 control arm, a drop in 

rotor speed, and subsequent loss of 

control of the helicopter. 

DATES: We must receive comments on 

this proposed AD by May 26, 2015. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Docket: Go to 

http://www.regulations.gov. Follow the 

online instructions for sending your 

comments electronically.

Discussion 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, issued EASA AD No. 2013–0154, 

dated July 22, 2013, to correct an unsafe 

condition for Eurocopter Deutschland 

GmbH (now AHD) Model MBB–BK117 

A–1, A–3, A–4, B–1, B–2, C–1, and 

C–2 helicopters. EASA advises of an 

incident with a Model MBB–BK117 

C–2 helicopter that dropped rotor speed 

(RPM) within the green range and could 

not be recovered to nominal value. 

According to EASA, an inspection of the 

engine N2 control system revealed a 

heavily corroded and broken N2 control 

arm. EASA advises that under certain 

flight conditions and power demands, a 

broken N2 control arm can cause a 

significant and non-recoverable drop in 

RPM. As a result, EASA AD No. 2013– 

0154 requires an initial and repetitive 

inspection of the N2 control arm for 

corrosion, damage, and scratches, and 

depending on the outcome of the 

inspection, repairing or replacing the N2 

control arm. 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of Germany 

and are approved for operation in the 

United States. Pursuant to our bilateral 

agreement with Germany, 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 

Eurocopter issued Alert Service 

Bulletin (ASB) MBB–BK117–60A–126 

for Model MBB–BK 117 A–1, A–3, A– 

4, B–1, B–2, and C–1 helicopters, and 

ASB MBB–BK117 C–2–6A–005 for 

Model MBB–BK 117 C–2 helicopters, 

both Revision 0, and both dated June 24, 

2013. The Eurocopter ASBs specify 

inspecting the N2 control arm for 

corrosion, damage, and scratches and, 

depending on the outcome of the 

inspection, either repairing or replacing 

the affected parts. The Eurocopter ASBs 

also specify performing the inspection 

with each 12-month inspection until the 

N2 inspection requirements are 

incorporated into the aircraft 

maintenance manual. This service 

information is reasonably available; see 

ADDRESSES for ways to access this 

service information. 

Proposed AD Requirements 

This proposed AD would require 

repetitive visual inspections of the N2 

control arm for corrosion, a crack, or a 

scratch. This proposed AD would 

require repairing any N2 control arm 

with corrosion or a scratch less than 

0.020 inch in depth and replacing any 

N2 control arm with exfoliation 

corrosion, a crack, or with corrosion or 

a scratch 0.020 inch or greater in depth. 

Differences Between This Proposed AD 

and the EASA AD 

The EASA AD allows a 

noncumulative tolerance of 3 months in 

the compliance time for the initial 

inspection on helicopters with less than 

2 years from the date of first flight and 

for the repetitive inspections, and this 

proposed AD would not. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 441 helicopters of U.S. 

Registry. We estimate that operators 

may incur the following costs in order 

to comply with this AD. Labor costs are 

estimated at $85 per work-hour. 

Inspecting the N2 control arm would 

require about one work-hour for an 

estimated cost of $85 per helicopter and 

$37,485 for the U.S. fleet per inspection 

cycle. Repairing the N2 control arm 

would require about four work-hours for 

an estimated labor cost of $340. 

Replacing the N2 control arm would 

require about three work-hours for an 

estimated labor cost of $255. Parts to 

replace the N2 control arm for Model 

MBB–BK 117 A–1, A–3, A–4, B–1, B–2, 

and C–1 helicopters would cost about 

$2,743 for a total estimated cost of 

$2,998. Parts to replace the N2 control 

arm for a Model MBB–BK 117 C–2 

helicopter would cost about $4,500 for 

a total estimated cost of $4,755. 

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.

applicable to your model helicopter. 

(i) If an N2 control arm has corrosion or a 

scratch less than 0.5 millimeter (mm) (0.020 

inch) in depth, before further flight, remove 

the corrosion and repair the scratch. 

(ii) If an N2 control arm has any exfoliation 

corrosion, a crack, or has corrosion or a 

scratch 0.5 mm (0.020 inch) or greater in 

depth, before further flight, replace the N2 

control arm.

(2) For operations conducted under a 14 

CFR part 119 operating certificate or under 

14 CFR part 91, subpart K, we suggest that 

you notify your principal inspector, or 

lacking a principal inspector, the manager of
