1516 Federal Register / Vol. 69, No. 6 / Friday, January 9, 2004 / Rules and Regulations 

Comments 

The public had the opportunity to 

participate in the development of this 

AD. No comments have been submitted 

on the proposed AD 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. 

Cost Impact 

The FAA estimates that 6 airplanes of 

U.S. registry will be affected by this AD, 

that it will take approximately 20 work 

hours to accomplish the replacement, 

and that the average labor rate is $65 per 

work hour. Required parts will cost 

approximately $500 per airplane. Based 

on these figures, the cost impact of the 

AD on U.S. operators is estimated to be 

$10,800, or $1,800 per airplane. 

The cost impact figure discussed 

above is based on assumptions that no 

operator has yet accomplished any of 

the requirements of this AD action, and 

that no operator would accomplish 

those actions in the future if this AD 

were not adopted. The cost impact 

figures discussed in AD rulemaking 

actions represent only the time 

necessary to perform the specific actions 

actually required by the AD. These 

figures typically do not include 

incidental costs, such as the time 

required to gain access and close up, 

planning time, or time necessitated by 

other administrative actions. 

Regulatory Impact 

The regulations adopted herein 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. Therefore, it is 

determined that this final rule does not 

have federalism implications under 

Executive Order 13132. 

For the reasons discussed above, I 

certify that this action (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. A final evaluation has 

been prepared for this action and it is 

contained in the Rules Docket. A copy 

of it may be obtained from the Rules 

Docket at the location provided under 

the caption ADDRESSES.

AGENCY: Federal Aviation 

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a 

new airworthiness directive (AD), 

applicable to certain EMBRAER Model 

EMB–135 and –145 series airplanes, that 

requires operators to inspect the pitottrue air temperature (TAT) relays and 

the full authority digital engine control 

(FADEC) electronic interface resistor 

modules to detect contamination. This 

AD also requires operators to perform 

corrective action if necessary, clean the 

relay/connector pins and sockets, 

modify the seal between the cockpit 

console panels and the storm window, 

and/or install a new protective frame 

(protective sheets) at the cockpit relay 

supports. This action is necessary to 

detect and correct oxidation of the pitotTAT relay, which could result in 

increased resistance and overheating of 

the relay and consequent smoke in the 

cockpit; and to detect and correct 

oxidation of the FADEC electronic 

interface resistor modules, which could 

result in in-flight uncommanded engine 

power roll back to idle. This action is 

intended to address the identified 

unsafe condition.

DATES: Effective February 13, 2004. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of February

SUPPLEMENTARY INFORMATION: A 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

include an airworthiness directive (AD) 

that is applicable to certain EMBRAER 

Model EMB–135 and –145 series 

airplanes was published as a 

supplemental NPRM in the Federal 

Register on September 8, 2003 (68 FR 

52865). The supplemental NPRM 

proposed to require operators to inspect 

the pitot-true air temperature (TAT) 

relays and the full authority digital 

engine control (FADEC) electronic 

interface resistor modules to detect 

contamination. The supplemental 

NPRM also proposed to require 

operators to perform corrective action if 

necessary, clean the relay/connector 

pins and sockets, modify the seal 

between the cockpit console panels and 

the storm window, and/or install a new 

protective frame (protective sheets) at 

the cockpit relay supports. 

Explanation of New Relevant Service 

Information 

The supplemental NPRM identified 

Change 03 of EMBRAER Service 

Bulletin 145–30–0032 as the appropriate 

source of service information for the 

inspection and modification. EMBRAER 

has since revised the service bulletin; 

however, Change 04, issued August 11, 

2003, adds no new actions. The 

Departmento de Aviacao Civil (DAC), 

which is the airworthiness authority for 

Brazil, approved Change 04 of the 

service bulletin. 

Paragraph (d) of the supplemental 

NPRM proposed to give credit for the 

protective sheet installation if already 

done in accordance with Change 06 of 

EMBRAER Service Bulletin 145–25–

0211. EMBRAER has since revised this 

service bulletin; however, Change 07, 

issued August 11, 2003, adds no new 

actions. In fact, EMBRAER considers 

that all versions, through Change 07, of 

this service bulletin accomplish the 

same work; i.e., subsequent versions to 

date have introduced no new actions. 

The DAC has approved all revisions of 

this service bulletin through Change 07. 

Comments 

Interested persons have been afforded 

an opportunity to participate in the 

making of this amendment. Due 

consideration has been given to the 

comments on the supplemental NPRM. 

Request To Revise Required Service 

Information 

One commenter requests that 

paragraphs (c) and (d) of the 

supplemental NPRM be revised to 

include the recently issued Change 04 of 

Service Bulletin 145–30–0032 as a 

compliance option. 

The FAA agrees, and considers 

Change 04 the primary source of service 

information for those requirements in 

this final rule. So that all operators are 

subject to the same, current 

requirements, paragraphs (c) and (d) of 

this AD require Change 04 of Service 

Bulletin 145–30–0032. In addition, 

paragraph (a) has been revised in this 

final rule to require Change 04 of this 

service bulletin. And new paragraph (e) 

has been added to this final rule to 

credit the prior accomplishment of 

actions done in accordance with earlier 

service bulletin versions.

Request To Credit Additional Service 

Bulletin Versions 

This same commenter requests that all 

versions of Service Bulletin 145–25–

0211, through Change 06, be allowed for 

credit for paragraphs (c) and (d) of the 

supplemental NPRM. The commenter 

states that all of its airplanes have been 

modified in accordance with earlier 

revision levels of that service bulletin. 

We agree with the request. As stated 

earlier, there are no essential differences 

among the revisions of this service 

bulletin. New paragraph (e) in this final 

rule provides credit accordingly. Change 

07, issued since we received the 

comment, is also included. 

Request To Allow Other Service 

Bulletin Versions 

The commenter notes that, when an 

AD cites a service bulletin that is later 

revised, an operator must request an 

alternative method of compliance 

(AMOC) to take credit for having used 

an earlier version or to use a later 

version of the specified service bulletin. 

The commenter therefore requests that 

paragraphs (a) and (c) of the 

supplemental NPRM be revised to allow 

the original issue of Service Bulletin 

145–30–0032, dated January 26, 2001, as 

well as any future revisions that have 

only minor changes. The commenter 

suggests that such a provision would 

reduce the requests for AMOCs. 

We do not agree with the request. We 

find that the procedures specified in the 

original issue and Revision 01 of Service 

Bulletin 145–30–0032 may not 

adequately address the identified unsafe 

condition. In addition, allowing ‘‘later 

FAA-approved revisions’’ of a service 

bulletin in addition to an AD’s specified 

version, would violate Office of the 

Federal Register (OFR) regulations for 

approving materials that are 

incorporated by reference. We must 

either publish the contents of the 

service bulletin as part of the text of the 

AD; or submit the service bulletin to the 

OFR for approval as ‘‘referenced’’

material, allowing us to simply refer to 

such material in the AD. To allow 

operators to use a revision issued after 

the AD was published, either we must 

revise the AD to refer to the specific 

revision, or, as the commenter notes, an 

operator must request an AMOC to use 

a later revision. 

Conclusion 

After careful review of the available 

data, including the comments noted 

above, we have determined that air 

safety and the public interest require the 

adoption of the rule 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. 

Cost Impact 

We estimate that 365 airplanes of U.S. 

registry will be affected by this AD. The 

following table provides the cost 

estimates for each requirement.

The cost impact figures discussed 

above are based on assumptions that no 

operator has yet accomplished any of 

the requirements of this AD, and that no 

operator would accomplish those 

actions in the future if this AD were not 

adopted. The cost impact figures 

discussed in AD rulemaking actions 

represent only the time necessary to 

perform the specific actions actually 

required by the AD. These figures 

typically do not include incidental 

costs, such as the time required to gain 

access and close up, planning time, or 

time necessitated by other 

administrative actions. 

Regulatory Impact 

The regulations adopted herein 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. Therefore, it is 

determined that this final rule does not 

have federalism implications under 

Executive Order 13132. 

For the reasons discussed above, I 

certify that this action (1) is not a

AGENCY: Federal Aviation 

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a 

new airworthiness directive (AD) for the 

specified Eurocopter France (ECF) 

model helicopters that requires revising 

the Limitations section of the Rotorcraft 

Flight Manual (RFM) to prohibit using 

the landing light except for landing and 

takeoff until the 40 amp 10P1 and 10P2 

contactors are replaced with 50 amp 

circuit breakers. Also, this amendment 

requires upgrading the electrical master 

boxes. This amendment is prompted by 

three reports of complete loss of 

electrical power generating systems, 

except for the direct battery power, due 

to a combination of high outside 

temperature and long flight duration 

with the landing light on that causes the 

nontemperature compensated trip 

switches to prematurely trip. The 

actions specified by this AD are 

intended to prevent failure of the 

helicopter power generator systems, loss 

of the use of flight instruments, and 

subsequent loss of control of the 

helicopter.

DATES: Effective February 13, 2004. 

The incorporation by reference of 

certain publications listed in the
