Subject 

(d) Air Transport Association (ATA) of 

America Code 23: Communications. 

Unsafe Condition 

(e) This AD results from an in-flight 

entertainment (IFE) systems review. We are 

proposing this AD to minimize the risk of 

smoke or flames in the passenger cabin by 

installing a switch in the flight compartment 

to enable the flightcrew to turn off electrical 

power to the IFE system and other nonessential electrical systems. In the event of 

smoke or flames in the airplane flight deck 

or passenger cabin, the flightcrew’s inability 

to turn off electrical power to the IFE system 

and other non-essential electrical systems 

could result in the inability to control smoke 

or flames in the airplane flight deck or 

passenger cabin during a non-normal or 

emergency situation. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Modification 

(g) Within 60 months after the effective 

date of this AD: Replace the mass memory 

card (MMC) with a new MMC; install new 

cabin system management unit (CSMU) 

software, cabin area control panel (CACP) 

software, and new zone management unit 

(ZMU) software; install new overhead 

electronics unit (OEU) operational program 

software, if applicable; install a new 

configuration database (CDB); and install the 

new CDB to the cabin service system; in 

accordance with the Accomplishment 

Instructions of Boeing Service Bulletin 777– 

23–0175, Revision 2, dated October 12, 2006. 

Concurrent Requirement 

(h) Prior to or concurrently with 

accomplishing the requirements of paragraph 

(g) of this AD, load the new cabin services 

system central storage device software and 

cabin system control panel operational 

software into the MMC, in accordance with 

Boeing Component Service Bulletin

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: Investigation conducted by 

Thales on probes revealed oil residue 

between the stator and the rotor parts of 

the AoA [angle of attack] vane position 

resolvers. This oil residue was due to 

incorrect cleaning of the machining oil 

during the manufacturing process of the 

AoA resolvers. At low temperatures, 

this oil residue becomes viscous 

(typically in cruise) causing lag of AoA 

vane movement. Such condition could 

lead to discrepant AoA measurement. If 

not corrected, and if two or three AoA 

probes were simultaneously affected 

and provided wrong indications of the 

AoA to a similar extent, it could lead to 

a late activation of the angle of attack 

protection, which in combination with 

light at high angle of attack would 

constitute an unsafe condition. The 

proposed AD would require actions that 

are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by August 23, 2010.

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 2010–0016R1, 

dated February 9, 2010 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

During Airbus Final Assembly Line 

reception flight tests, AoA [angle of attack] 

data from two different aeroplanes were 

found inaccurate. Inaccuracy was confirmed 

by flight data analysis. 

Investigation conducted by Thales on the 

removed probes revealed oil residue between 

the stator and the rotor parts of the AoA vane 

position resolvers. This oil residue was due 

to incorrect cleaning of the machining oil 

during the manufacturing process of the AoA 

resolvers. At low temperatures, this oil 

residue becomes viscous (typically in cruise) 

causing lag of AoA vane movement. 

Such condition could lead to discrepant 

AoA measurement. If not corrected, and if 

two or three AoA probes were 

simultaneously affected and provided wrong 

indications of the AoA to a similar extent, it 

could lead to a late activation of the angle of 

attack protection, which in combination with 

flight at high angle of attack would constitute 

an unsafe condition. 

Therefore, this [EASA] AD requires a one 

time inspection of the Thales Avionics AoA 

probe P/N [part number] C16291AA in order 

to identify the suspect parts and to remove 

them from service. 

This [EASA] AD revision is issued to 

specify that the identification of the affected 

AoA probes is also possible in accordance 

with aeroplane maintenance records data 

analysis. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued the service 

bulletins specified in the following 

table. Thales Avionics has issued 

Service Bulletin C16291A–34–007, 

Revision 01, dated December 3, 2009. 

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. 

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 proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 44 products of U.S. registry. 

(There are currently no Model A340 

airplanes on the U.S. Register.) We also 

estimate that it would take about 3 

work-hours per product to comply with 

the basic requirements of this proposed 

AD. The average labor rate is $85 per 

work-hour. Based on these figures, we 

estimate the cost of the proposed AD on 

U.S. operators to be $11,220, or $255 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.

Federal Register / Vol. 75, No. 129 / Wednesday, July 7, 2010 / Proposed Rules 38949 

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); 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 proposed AD and placed it in the 

AD docket.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new AD: 

Airbus: Docket No. FAA–2010–0675; 

Directorate Identifier 2010–NM–061–AD. 

Comments Due Date 

(a) We must receive comments by August 

23, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to the airplanes 

identified in paragraphs (c)(1) and (c)(2) of 

this AD. 

(1) Airbus Model A330–201, A330–202, 

A330–203, A330–223, A330–243, A330–301, 

A330–302, A330–303, A330–321, A330–322, 

A330–323, A330–341, A330–342 and A330– 

343 airplanes, certificated in any category; all 

manufacturer serial numbers, equipped with 

Thales Avionics angle of attack (AOA) probe 

having part number (P/N) C16291AA. 

(2) Airbus Model A340–211, A340–212, 

A340–213, A340–311, A340–312, A340–313, 

A340–541, and A340–642 airplanes, 

certificated in any category, all manufacturer 

serial numbers, equipped with Thales 

Avionics AOA probe having P/N C16291AA. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 34: Navigation. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

During Airbus Final Assembly Line 

reception flight tests, AoA data from two 

different aeroplanes were found inaccurate. 

Inaccuracy was confirmed by flight data 

analysis. 

Investigation conducted by Thales on the 

removed probes revealed oil residue between 

the stator and the rotor parts of the AoA vane 

position resolvers. This oil residue was due 

to incorrect cleaning of the machining oil 

during the manufacturing process of the AoA 

resolvers. At low temperatures, this oil 

residue becomes viscous (typically in cruise) 

causing lag of AoA vane movement. 

Such condition could lead to discrepant 

AoA measurement. If not corrected, and if 

two or three AoA probes were 

simultaneously affected and provided wrong 

indications of the AoA to a similar extent, it 

could lead to a late activation of the angle of 

attack protection, which in combination with 

flight at high angle of attack would constitute 

an unsafe condition. 

Therefore, this [European Aviation Safety 

Agency (EASA)] AD requires a one time 

inspection of the Thales Avionics AoA probe 

P/N C16291AA in order to identify the 

suspect parts and to remove them from 

service. 

This [EASA] AD revision is issued to 

specify that the identification of the affected 

AoA probes is also possible in accordance 

with aeroplane maintenance records data 

analysis. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Inspection of AOA Probes 

(g) Within 3 months after the effective date 

of this AD, perform a detailed visual 

inspection of the Thales Avionics AOA 

probes having P/N C16291AA for a serial 

number identification, in accordance with 

the instructions of the applicable service 

information identified in Table 1 of this AD. 

A review of airplane maintenance records is 

acceptable in lieu of this inspection if the 

serial number of the AOA probe can be 

conclusively determined from that review. If 

no AOA probe having P/N C16291AA and a 

serial number identified in Thales Service 

Bulletin C16291A–34–007, Revision 01, 

dated December 3, 2009, is identified during 

the inspection required by this paragraph of 

this AD, no further action is required by this 

AD, except for paragraph (i) of this AD.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Model 727 airplanes. This proposed AD 

would require inspections for scribe 

lines in the fuselage skin at skin lap 

joints and butt joints, the skin at certain 

external approved repairs, the skin 

around external features such as 

antennas, and the skin at decals and 

fairings; and related investigative and 

corrective actions if necessary. This 

proposed AD results from reports of 

scribe lines found at skin lap joints and 

butt joints, around external repairs and 

antennas, and at locations where 

external decals had been cut. We are 

proposing this AD to detect and correct 

scribe lines, which can develop into 

fatigue cracks in the skin and cause 

rapid decompression of the airplane. 

DATES: We must receive comments on 

this proposed AD by August 23, 2010. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to
