ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for Airbus 

Helicopters Deutschland GmbH (Airbus 

Helicopters) MBB–BK 117 D–2

trusses of both engines. This proposed 

AD is prompted by reports of 

delaminated and worn engine mount 

bushings. The proposed actions are 

intended to detect delaminated engine 

mount bushings, which can lead to 

excessive vibration, cracking, failure of 

the engine mount front support pins, 

and loss of helicopter control.

Discussion 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD No. 2015– 

0198, dated September 30, 2015, to 

correct an unsafe condition for Airbus 

Helicopters Model MBB–BK 117 D–2 

helicopters. EASA advises that during a 

pre-flight check of an MBB–BK 117 D– 

2 helicopter, an engine mount bushing 

was found delaminated. More cases of 

delaminated engine mount bushings 

were reported following additional 

investigations. According to EASA, this 

condition could lead to cracks and 

eventually failure of the engine mount 

front support pins, possibly resulting in 

loss of helicopter control. 

The EASA AD consequently requires 

repetitive inspections of the engine 

mount bushings and depending of the 

findings, repairing or replacing the 

bushings. 

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 

We reviewed Airbus Helicopters Alert 

Service Bulletin (ASB) MBB–BK117 D– 

2–71A–002, Revision 0, dated 

September 28, 2015, for Model MBB–BK 

117 D–2 helicopters. The ASB 

introduces repetitive visual inspections 

of the engine mount bushings for 

defects, deformation, separation of the 

rubber, and missing rubber after reports 

of delaminated engine mount bushings 

and bushings with damage to the metal 

inner sleeve. If there is any deformation 

or separation of the rubber, the ASB 

specifies performing a detailed 

inspection of the bushing in accordance 

with the aircraft maintenance manual. 

Proposed AD Requirements 

This proposed AD would require 

within 50 hours time-in-service (TIS) 

and at intervals not to exceed 50 hours 

TIS thereafter, visually inspecting the 

bushings of the inner and outer forward 

trusses of both engines, and depending 

on the outcome of the inspections, 

replacing or repairing the bushings 

before further flight. 

Differences Between This Proposed AD 

and the EASA AD 

The EASA AD allows for a 10 hour 

time-in-service, non-cumulative 

tolerance for its required compliance 

times. This proposed AD would not. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 5 helicopters of U.S. 

Registry and that labor costs average $85 

per work hour. Based on these 

estimates, we expect the following costs: 

• Inspecting the bushings would 

require 1 work hour. No parts would be 

needed, for a total cost of $85 per 

helicopter and $425 for the U.S. fleet. 

• Replacing a bushing would require 

1 work hour and $373 for parts, for a 

total cost of $458 per bushing. 

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.

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is proposing to approve 

and disapprove elements of State 

Implementation Plan (SIP) submissions 

from the State of Oklahoma for the 2012 

Fine Particulate Matter (PM2.5) National 

Ambient Air Quality Standard (NAAQS 

or standard) and the 2010 Sulfur 

Dioxide (SO2) NAAQS. The 2012 PM2.5

submission addresses how the existing 

SIP provides for implementation, 

maintenance, and enforcement of this 

NAAQS (infrastructure SIP or i-SIP). 

The i-SIP ensures that the Oklahoma SIP 

is adequate to meet the State’s 

responsibilities under the Federal Clean 

Air Act (CAA). The majority of the 2010 

SO2 submission was addressed in a 

separate rulemaking, only the visibility 

component listed in 110(a)(2)(D)(i)(II) is 

being addressed in this action. 

We are proposing to disapprove the 

visibility component of 

110(a)(2)(D)(i)(II), often referred to as 

prong 4. We are also proposing to 

disapprove the portion of the January 

28, 2015 SIP submission from Oklahoma 

for the 2010 Sulfur Dioxide (SO2) 

NAAQS only as it addresses Section 

110(a)(2)(D)(i)(II) for visibility 

protection.

I. Background 

On October 17, 2006, following a 

periodic review of the NAAQS for 

PM2.5, EPA revised the PM2.5 NAAQS. 

The 24-hour standard was revised to 35 

micrograms per cubic meter (mg/m3), 

and the annual standard was revised to 

15 mg/m3 (71 FR 61144). On December 

14, 2012, we promulgated a revised
