AGENCY: Federal Aviation 

Administration (FAA), Department of

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

* * * * * 

[C]hafed wirings were found in the rear 

baggage zone, closed [close] to the forward 

side of the aft pressure bulkhead, due to 

contact with an understructure securing 

screw. The concerned wiring harness 

includes rudder trim, pitch trim and stick 

pusher control wires. Damages on those 

wires might lead to the loss of fail safe 

criteria for those critical functions. 

* * * * * 

The unsafe condition is reduced 

controllability of the airplane. We are 

issuing this AD to require actions to 

correct the unsafe condition on these 

products. 

DATES: This AD becomes effective July 

16, 2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of July 16, 2009. 

ADDRESSES: You may examine the AD 

docket on the Internet at http://

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on November 26, 2008 (73 FR 

71961). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

One ATR operator reported some spurious 

‘‘Pitch disconnect’’ warning and ‘‘AIL and R 

ELEV’’ Anti-Ice Horn Fault caution 

annunciations which precluded the use of 

the autopilot. 

During the investigation, chafed wirings 

were found in the rear baggage zone, closed 

[close] to the forward side of the aft pressure 

bulkhead, due to contact with an 

understructure securing screw. The 

concerned wiring harness includes rudder 

trim, pitch trim and stick pusher control 

wires. Damages on those wires might lead to 

the loss of fail safe criteria for those critical 

functions. 

To address the identified unsafe condition, 

this AD mandates a one-time inspection and 

a routing modification of the electrical wires 

in the bulkhead area. 

The unsafe condition is reduced 

controllability of the airplane. The 

corrective action also includes 

contacting ATR for repair instructions 

and doing the repair if any damage 

(chafing or contact between bundles of 

cables and the airframe structure) is 

found during the one-time inspection. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Explanation of Change to the NPRM 

We have revised paragraph (c) of the 

AD to coincide with the effectivity of 

the European Aviation Safety Agency 

(EASA) AD. 

Explanation of Revised Service 

Information 

ATR has issued the service bulletins 

identified in the following table.

These service bulletins differ from the 

original issues of those service bulletins, 

all dated February 11, 2008 (which were 

referenced in the NPRM), by including 

clarifications and editorial changes that 

do not affect the technical content. This 

AD does not require the ‘‘Additional 

Work’’ described in ATR Service 

Bulletins ATR42–92–0018 and ATR72– 

92–1018, both Revision 01, both dated 

September 4, 2008. 

We have changed paragraphs (f)(1), 

(f)(2), and (f)(3) of this AD to refer to the 

most recent revisions of the service 

bulletins identified in the previous 

table, and added paragraph (f)(4) of this 

AD to give credit for actions done 

according to the prior issues identified 

in the following table.

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We determined these changes will not 

increase the economic burden on any 

operator or increase the scope of the AD. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

48 products of U.S. registry. We also 

estimate that it will take about 5 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $80 per work-hour. 

Required parts will cost about $131 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 this AD 

to the U.S. operators to be $25,488, or 

$531 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 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 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 this AD: 

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); 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. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

section. Comments will be available in 

the AD docket shortly after receipt.

which ATR Service Bulletin ATR72–92–1018 

has been incorporated. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 24: Electrical power. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

‘‘One ATR operator reported some 

spurious ‘‘Pitch disconnect’’ warning and 

‘‘AIL and R ELEV’’ Anti-Ice Horn Fault 

caution annunciations which precluded the 

use of the autopilot. 

‘‘During the investigation, chafed wirings 

were found in the rear baggage zone, closed 

[close] to the forward side of the aft pressure 

bulkhead, due to contact with an 

understructure securing screw. The 

concerned wiring harness includes rudder 

trim, pitch trim and stick pusher control 

wires. Damages on those wires might lead to 

the loss of fail safe criteria for those critical 

functions. 

‘‘To address the identified unsafe 

condition, this AD mandates a one-time 

inspection and a routing modification of the 

electrical wires in the bulkhead area.’’ 

The unsafe condition is reduced 

controllability of the airplane. The corrective 

action also includes contacting ATR for 

repair instructions and doing the repair if any 

damage (chafing or contact between bundles 

of cables and the airframe structure) is found 

during the one-time inspection. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) Within 550 flight hours after the 

effective date of this AD, perform a one-time 

detailed inspection for damage of the 

electrical routing in the rear baggage zone, in 

accordance with the Accomplishment 

Instructions of ATR Service Bulletin ATR42– 

92–0015 or ATR72–92–1016, both Revision 

01, both dated February 11, 2009, as 

applicable. 

(2) If any damage is found during the 

inspection required by paragraph (f)(1) of this 

AD, do the actions in paragraphs (f)(2)(i) and 

(f)(2)(ii) of this AD. 

(i) Before further flight, contact ATR for 

repair instructions, and do the repair. 

(ii) Before further flight, modify the 

electrical routing and protective sleeve in the 

rear cargo compartment at frame 44 in 

accordance with the Accomplishment 

Instructions of ATR Service Bulletin ATR42– 

92–0018 or ATR72–92–1018, both Revision 

02, both dated February 13, 2009, as 

applicable. 

(3) If no damage is found during the 

inspection required by paragraph (f)(1) of this 

AD: Within 5,000 flight hours after the 

effective date of this AD, modify the 

electrical routing and replace the protective 

sleeve in the rear cargo compartment at frame 

44 in accordance with the Accomplishment 

Instructions of ATR Service Bulletin ATR42– 

92–0018 or ATR72–92–1018, both Revision 

02, both dated February 13, 2009, as

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Boeing Model 737–300, –400, –500, 

–600, –700, –700C, –800, and –900 

series airplanes. This AD requires 

installing a new circuit breaker, relays, 

and wiring to allow the flightcrew to 

turn off electrical power to the in-flight 

entertainment (IFE) systems and other 

non-essential electrical systems through 

a switch in the flight compartment, and 

doing other specified actions. This AD 

results from an IFE systems review. We 

are issuing this AD to ensure that the 

flightcrew is able to turn off electrical 

power to IFE systems and other nonessential electrical systems through a 

switch in the flight compartment. The 

flightcrew’s inability to turn off power 

to IFE systems and other non-essential 

electrical systems during a non-normal 

or emergency situation could result in 

the inability to control smoke or fumes 

in the airplane flight deck or cabin. 

DATES: This AD is effective July 16, 

2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of July 16, 2009.

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness

certain Boeing Model 737–300, –400, 

–500, –600, –700, –700C, –800, and 

–900 series airplanes. That NPRM was

NPRM proposed to require installing a 

new circuit breaker, relays, and wiring 

to allow the flightcrew to turn off
