Airworthiness Directives; Airbus 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Airbus Model A330–200 freighter series 

airplanes; Model A330–200 and –300 

series airplanes; and Model A340–200 

and –300 series airplanes. This 

proposed AD was prompted by reports 

of ram air turbine (RAT) pump failure. 

This proposed AD would require 

inspecting the RAT pump anti-stall 

valve for correct setting, re-identifying 

the RAT pump, performing a functional 

ground test of the RAT, and replacing 

the RAT pump or the RAT assembly 

with a serviceable part if necessary. We 

are proposing this AD to detect and 

correct malfunction of the RAT pump, 

which could lead to in-flight loss of the 

RAT-pump pressurization, possibly 

resulting in reduced control of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by August 27, 2012. 

ADDRESSES: You may send comments by 

any of the following methods:

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 2011–0197, 

dated October 10, 2011 (referred to after 

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

condition for the specified products. 

The MCAI states: 

During a test flight before delivery from 

production, an A330 aeroplane experienced 

a RAT [ram air turbine] pump failure, as a 

result of which, the green hydraulic system 

could not be fully pressurized. 

Investigations concluded that this 

malfunction was due to poor installation of 

the anti-stall valve sleeve, causing a shift in 

the anti-stall speed setting and leading to an 

inability of the hydraulic pump Part Number 

(P/N) 5909522 to provide enough hydraulic 

pressure. 

This condition, if not detected and 

corrected, could lead to the in-flight loss of 

the RAT-Pump pressurization which, in case 

of a total engine flame out, could have 

consequences for the hydraulic circuits, 

possibly resulting in reduced control of the 

aeroplane. A340–500/–600 series aeroplanes 

are not affected by this issue because they are 

fitted with a different hydraulic pump P/N. 

For the reasons described above, this 

[EASA] AD requires a check to ensure correct 

setting of the RAT anti-stall valve in the 

pump housing, followed by a RAT functional 

ground test, and accomplishment of the 

applicable corrective actions, depending on 

findings. 

Corrective actions include replacing the 

RAT pump or the RAT assembly with a 

serviceable part. Required actions 

include reporting the findings of the 

inspection. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Airbus has issued Mandatory Service 

Bulletin A330–29–3117, dated July 19, 

2011 (for Model A330 airplanes); and 

Mandatory Service Bulletin A340–29– 

4090, dated July 19, 2011 (for Model 

A340 airplanes). 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 


erowe on DSK2VPTVN1PROD with PROPOSALS-1
Federal Register / Vol. 77, No. 133 / Wednesday, July 11, 2012 / Proposed Rules 40831 

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 59 products of U.S. registry. 

We also estimate that it would take 

about 4 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 

$20,060, or $340 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 7 work-hours and require parts 

costing up to $405,143, for a cost of up 

to $405,738 per product. We have no 

way of determining the number of 

products that may need these actions. 

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 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.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 747–400, 

and –400F series airplanes. This 

proposed AD was prompted by multiple 

reports of integrated display unit (IDU) 

malfunctions and mode control panel 

(MCP) malfunctions. This proposed AD 

would require installing new software, 

replacing the duct assembly with a new 

duct assembly, making wiring changes, 

and routing certain wire bundles. We 

are proposing this AD to prevent IDU 

malfunctions, which could affect the 

ability of the flight crew to read primary 

displays for airplane attitude, altitude, 

or airspeed, and consequently reduce 

the ability of the flight crew to maintain 

control of the airplane. 

DATES: We must receive comments on 

this proposed AD by August 27, 2012. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
