AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

EMBRAER Model EMB–120, –120ER, 

–120FC, –120QC, and –120RT airplanes. 

This AD requires modifying electrical 

harnesses located at the left- and righthand wing roots; and re-routing and 

modifying the harness of the right-hand 

outboard flap actuator. This AD results 

from fuel system reviews conducted by 

the manufacturer. We are issuing this 

AD to prevent chafed electrical 

harnesses, which could result in a 

potential source of ignition for fuel 

vapors near a fuel tank and consequent 

fire or fuel tank explosion. 

DATES: This AD becomes effective 

January 9, 2006. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of January 9, 2006.

Examining the Docket 

You may examine the airworthiness 

directive (AD) docket on the Internet at 

http://dms.dot.gov or in person at the 

Docket Management Facility office 

Federal Register / Vol. 70, No. 232 / Monday, December 5, 2005 / Rules and Regulations 72367 

between 9 a.m. and 5 p.m., Monday 

through Friday, except Federal holidays. 

The Docket Management Facility office 

(telephone (800) 647–5227) is located on 

the plaza level of the Nassif Building at 

the street address stated in the 

ADDRESSES section. 

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to all EMBRAER Model EMB–120, 

–120ER, –120FC, –120QC, and –120RT 

airplanes. That NPRM was published in 

the Federal Register on October 7, 2005 

(70 FR 58626). That NPRM proposed to 

require modifying electrical harnesses 

located at the left- and right-hand wing 

roots; and re-routing and modifying the 

harness of the right-hand outboard flap 

actuator. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed. 

Costs of Compliance 

This AD will affect about 112 

airplanes of U.S. registry. The actions 

will take about 8 work hours per 

airplane, at an average labor rate of $65 

per work hour. Required parts will cost 

about $979 per airplane. Based on these 

figures, the estimated cost of the AD for 

U.S. operators is $167,888, or $1,499 per 

airplane. 

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 AD will 

not have federalism implications under 

Executive Order 13132. This AD will 

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 this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

(2) Is not a ‘‘significant rule’’ under 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

(3) 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 AD and placed it in the AD docket. 

See the ADDRESSES section for a location 

to examine the regulatory evaluation.

Airworthiness Directives; Aerospatiale 

Model ATR42–200, ATR42–300, and 

ATR42–320 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD), 

which applies to all Aerospatiale Model 

ATR42–200, ATR42–300, and ATR42–

320 airplanes. That AD currently 

requires inspections to determine the 

proper installation of rivets in certain 

key holes and to detect cracks in the 

area of the key holes where rivets are 

missing; and correction of 

discrepancies. The existing AD also 

requires various inspections of the 

subject area for discrepancies, and 

corrective actions if necessary; and 

replacement of certain cargo door hinges 

with new hinges. For certain airplanes, 

the existing AD also requires 

replacement of friction plates, stop 

fittings, and bolts with new parts. This 

new AD requires additional corrective 

actions for certain airplanes. This AD 

results from discovery of cracks around 

key holes on certain fuselage frames 

where rivets were missing. We are 

issuing this AD to prevent fatigue cracks 

of the cargo door skin, certain frames, 

and entry door stop fittings and friction 

plates, which could result in reduced 

structural integrity of the airplane. 

DATES: This AD becomes effective 

January 9, 2006. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of January 9, 2006. 

On April 26, 2000 (65 FR 15226, 

March 22, 2000), the Director of the 

Federal Register approved the 

incorporation by reference of certain 

other publications. 

On November 18, 1993 (58 FR 53853,

SUPPLEMENTARY INFORMATION: 

Examining the Docket 

You may examine the airworthiness 

directive (AD) docket on the Internet at 

http://dms.dot.gov or in person at the 

Docket Management Facility office 

between 9 a.m. and 5 p.m., Monday 

through Friday, except Federal holidays. 

The Docket Management Facility office 

(telephone (800) 647–5227) is located on 

the plaza level of the Nassif Building at 

the street address stated in the 

ADDRESSES section. 

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that 

supersedes AD 2000–05–26, amendment 

39–11636 (65 FR 15226, March 22, 

2000). The existing AD applies to all 

ATR42–200, ATR42–300 and ATR42–

320 airplanes. That NPRM was 

published in the Federal Register on 

September 19, 2005 (70 FR 54856). That 

NPRM proposed to continue to require 

inspections to determine the proper 

installation of rivets in certain key holes 

and to detect cracks in the area of the 

key holes where rivets are missing; and 

correction of discrepancies. That NPRM 

also proposed to continue to require 

various inspections of the subject area 

for discrepancies, and corrective actions 

if necessary; and replacement of certain 

cargo door hinges with new hinges. For 

certain airplanes, that NPRM proposed 

to continue to require replacement of 

friction plates, stop fittings, and bolts 

with new parts. That NPRM further 

proposed to require additional 

corrective actions for certain airplanes. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. No comments 

have been received on the NPRM or on 

the determination of the cost to the 

public. 

Clarification of Effective Date 

We have revised Note 2 of this AD to 

include the effective date of AD 2000–

05–26. 

Clarification of Alternative Method of 

Compliance (AMOC) Paragraph 

We have revised this action to clarify 

the appropriate procedure for notifying 

the principal inspector before using any 

approved AMOC on any airplane to 

which the AMOC applies. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD with the changes 

described previously. We have 

determined that these changes will 

neither increase the economic burden 

on any operator nor increase the scope 

of the AD. 

Costs of Compliance 

This AD will affect about 106 

Aerospatiale Model ATR42–200, 

ATR42–300, and ATR42–320 airplanes 

of U.S. registry. 

The general visual inspection of 

fuselage frames 25 and 27 that is 

required by AD 2000–05–26 and
