ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model DC–10–10 

and MD–10–10F airplanes. This 

proposed AD was prompted by a report 

that the safe life limit on certain main 

landing gear (MLG) upper torque link 

bolts is reduced significantly due to 

incorrect fabrication. This proposed AD 

would require replacing certain MLG 

upper torque link bolts with a new or 

serviceable part. We are proposing this 

AD to prevent damage to the MLG and 

consequent damage to airplane 

structure, which could adversely affect 

the airplane’s continued safe flight and 

landing.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2012–0680; Directorate Identifier 2011– 

NM–247–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We have received a report that the 

safe life limit on certain MLG upper 

torque link bolts is reduced significantly 

due to incorrect fabrication. This 

condition, if not corrected, could result 

in damage to the MLG and consequent 

damage to airplane structure, which 

could adversely affect the airplane’s 

continued safe flight and landing. 

Relevant Service Information 

We reviewed Boeing Alert Service 

Bulletin DC10–32A260, dated 

September 30, 2011. The service 

information describes procedures for 

replacing certain MLG upper torque link 

bolts with a new or serviceable part. 

Explanation of Proposed Compliance 

Time 

Boeing Alert Service Bulletin DC10– 

32A260, dated September 30, 2011, 

specifies a compliance time of ‘‘before 

further flight or before 6,590 flight 

cycles from installation,’’ for replacing 

the MLG upper torque link bolt. This 

proposed AD would change the 

compliance time to ‘‘within 6,590 flight 

cycles from bolt installation or within 

180 days after the effective date of this 

AD, whichever occurs later.’’ We have 

determined that this compliance time 

would provide adequate time for the 

actions to be done without grounding 

airplanes. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design.

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 17 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Bolt Replacement ................... 2 work-hours × $85 per hour = $170 ..................................... $9,340 $9,510 $161,670 

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.

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.

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.

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
