ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

ATR–GIE Avions de Transport Re ́gional 

Model ATR72–101, –201, –102, –202, 

–211, –212, and –212A airplanes. This 

proposed AD was prompted by reports 

of airplane incidents and accidents that 

have occurred because of low-level fuel 

tank situations and fuel starvation that 

resulted in engine flameouts. This 

proposed AD would require installing a

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2013–0047, 

dated March 4, 2013 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

Large aeroplane incidents and accidents 

have occurred because of fuel tank low level 

situations, or because of fuel starvation, 

resulting in one or several engine(s) flameout. The results of the investigation into an 

ATR 72 accident in August 2005 have shown 

that overruling standard operational 

procedures and maintenance practices have 

led to this kind of occurrence. 


pmangrum on DSK3VPTVN1PROD with PROPOSALS-1
Federal Register / Vol. 78, No. 138 / Thursday, July 18, 2013 / Proposed Rules 42899 

Consequently, additional actions to help 

avoid maintenance errors, like installation of 

a wrong gauge or wrong indicator, need to be 

taken. 

Although it is recognised that the fuel 

(indicating) system of the ATR42/72 type 

design is compliant with the applicable 

requirements, the risk of other maintenance 

errors will be mitigated by making 

installation of an ATR 42 Fuel Quantity 

Indicator (FQI) on an ATR 72 aeroplane 

mechanically impossible through a specific 

design change on the ATR 72. 

For the reasons described above, this 

[EASA] AD requires modification of the ATR 

72 FQI by installing a locking adaptor on the 

electrical connector. 

We are proposing this AD to prevent an 

engine flame-out, which could result in 

reduced controllability of the airplane. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Avions de Transport Re ́gional has 

issued Service Bulletin ATR72–28– 

1026, dated February 26, 2013. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 25 products of U.S. registry. 

We also estimate that it would take 

about 2 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $3,882 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$101,300, or $4,052 per product. 

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 proposed 

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 above, 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; 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 a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 727 

airplanes. This proposed AD is intended 

to complete certain mandated programs 

intended to support the airplane 

reaching its limit of validity (LOV) of 

the engineering data that support the 

established structural maintenance 

program. This proposed AD would 

require an inspection for cracks in the 

main wheel well pressure floor and a 

preventive modification or permanent 

repair, as applicable. We are proposing 

this AD to prevent cracking in the main 

wheel well pressure floor, which could 

result in reduced structural integrity of 

the airplane, and decompression of the 

cabin.

Discussion 

As described in FAA Advisory 

Circular 120–104 (http://www.faa.gov/

documentLibrary/media/Advisory_

Circular/120-104.pdf), several programs 

have been developed to support 

initiatives that will ensure the 

continued airworthiness of aging 

airplane structure. The last element of 

those initiatives is the requirement to 

establish a LOV of the engineering data 

that support the structural maintenance 

program under 14 CFR 26.21. This 

proposed AD is the result of an 

assessment of the previously established 

programs by The Boeing Company 

during the process of establishing the 


pmangrum on DSK3VPTVN1PROD with PROPOSALS-1
