Airworthiness Directives; Austro

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to the products listed above. 

The existing AD currently requires 

frequent inspections of the fuel pressure 

supply for excessive oscillations to 

determine if high-pressure fuel pumps 

have been exposed to damaging 

pressure oscillations. Pumps that have 

been exposed require replacement 

before further flight. Since we issued 

that AD, Austro Engine, the 

manufacturer of the pump, introduced a 

new part number (P/N) fuel pump as 

mandatory terminating action to the 

repetitive inspections. This proposed 

AD would require the initial and 

repetitive inspections of AD 2010–23– 

09, but would also require installing HP 

fuel pump P/N E4A–30–200–000, as 

mandatory terminating action to the 

repetitive inspections. We are proposing 

this AD to prevent engine power loss or 

in-flight shutdown, which could result 

in loss of control of the airplane. 

DATES: We must receive comments on 

this proposed AD by July 25, 2011. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

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

instructions for submitting comments.

Discussion 

On October 27, 2010, we issued AD 

2010–23–09, Amendment 39–16498 (75 

FR 68179, November 5, 2010), for 

Austro Engine GmbH model E4 diesel 


jlentini on DSK4TPTVN1PROD with PROPOSALS
Federal Register / Vol. 76, No. 111 / Thursday, June 9, 2011 / Proposed Rules 33661 

piston engines. That AD requires 

frequent inspections of the fuel pressure 

supply for excessive oscillations to 

determine if high-pressure fuel pumps 

have been exposed to damaging 

pressure oscillations. Pumps that have 

been exposed require replacement 

before further flight. That AD resulted 

from the European Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Community, issuing 

emergency AD 2010–0206–E, dated 

October 8, 2010 to correct that same 

unsafe condition. We issued our AD to 

prevent engine power loss or in-flight 

shutdown, which could result in loss of 

control of the airplane. 

Actions Since Existing AD Was Issued 

Since we issued AD 2010–23–09, 

EASA issued AD 2011–0039, dated 

March 8, 2011, adding a terminating 

action on Austro Engine GmbH model 

E4 diesel piston engines. 

Relevant Service Information 

We reviewed Austro Engine GmbH 

Work Instruction No. WI–MSB–E4–009, 

dated October 7, 2010, and Austro 

Engine GmbH Mandatory Service 

Bulletin No. MSB–E4–009/2, dated 

March 4, 2011. The actions described in 

this service information are intended to 

prevent engine power loss or in-flight 

shutdown, which could result in loss of 

control of the airplane. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would retain all 

the requirements of AD 2010–23–09, 

and require installing HP fuel pump 

P/N E4A–30–200–000, as mandatory 

terminating action to the repetitive 

inspections. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD will 

affect about 32 model E4 diesel piston 

engines, installed on airplanes of U.S. 

registry. We also estimate that it will 

take about 1 work-hour per engine to 

perform one inspection, and about 2 

work-hours per engine to replace the HP 

fuel pump. The average labor rate is $85 

per work-hour. Required parts will cost 

about $2,325 per product. Based on 

these figures, we estimate the cost of the 

AD on U.S. operators to be $82,560. 

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 have 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 above, I 

certify that the 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, 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference,

Approval and Promulgation of Air 

Quality Implementation Plans; State of 

Tennessee; Regional Haze State 

Implementation Plan 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: EPA is proposing a limited 

approval and a limited disapproval of a 

revision to the Tennessee State 

Implementation Plan (SIP) submitted by 

the State of Tennessee through the 

Tennessee Department of Environment 

and Conservation (TDEC) on April 4, 

2008, that addresses regional haze for 

the first implementation period. This 

revision addresses the requirements of 

the Clean Air Act (CAA) and EPA’s 

rules that require states to prevent any 

future and remedy any existing 

anthropogenic impairment of visibility 

in mandatory Class I areas caused by 

emissions of air pollutants from 

numerous sources located over a wide 

geographic area (also referred to as the 

‘‘regional haze program’’). States are 

required to assure reasonable progress 

toward the national goal of achieving 

natural visibility conditions in Class I 

areas. EPA is proposing a limited 

approval of this SIP revision to 

implement the regional haze 

requirements for Tennessee on the basis 

that the revision, as a whole, 

strengthens the Tennessee SIP. Also in 

this action, EPA is proposing a limited 

disapproval of this same SIP revision 

because of the deficiencies in the State’s 

April 2008 regional haze SIP submittal 

arising from the remand by the U.S. 

Court of Appeals for the District of 

Columbia (DC Circuit) to EPA of the 

Clean Air Interstate Rule (CAIR).
