compliance times specified, unless already 

done. 

(g) Inspection and Replacement 

(1) Before the accumulation of 15,000 total 

flight hours since the airplane’s first flight, or 

within 6,000 flight hours after the effective 

date of this AD, whichever occurs later, do 

a high frequency eddy current (HFEC) 

inspection for cracking on the lower area of 

rib 5 on the left-hand and right-hand side 

pylons, in accordance with the 

Accomplishment Instructions of Airbus 

Mandatory Service Bulletin A300–54–6034, 

Revision 02, dated August 26, 2013. Repeat 

the inspection thereafter at intervals not to 

exceed 15,000 flight hours. 

(2) If any crack is found during any 

inspection required by paragraph (g)(1) of 

this AD, before further flight, replace all the 

fittings with new standard fittings, in 

accordance with the Accomplishment

paragraph (g)(2) of this AD, or modification 

of pylons in accordance with the 

Accomplishment Instructions of Airbus 

Service Bulletin A300–54–6031, dated May 

30, 1996, terminates the repetitive HFEC 

inspections required by paragraph (g)(1) of 

this AD. 

(i) Credit for Previous Actions 

This paragraph provides credit for the 

inspections required by paragraph (g)(1) of 

this AD, if those actions were performed 

before the effective date of this AD using

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, 

A330–200 and –300, and A340–200, 

–300, –500, and –600 series airplanes. 

This proposed AD was prompted by 

reassessment of an unsafe condition 

related to MZ-type spoiler servocontrols (SSCs) that did not remain 

locked in the retracted position 

(hydraulic locking function) after 

manual depressurization of the 

corresponding hydraulic circuit. This 

reassessment resulted in the 

determination that performing repetitive 

operational tests of all SSC types is 

necessary. This proposed AD would 

require repetitive operational tests of the 

hydraulic locking function on each SSC 

installed on the blue or yellow 

hydraulic circuits, and replacing any 

affected SSC with a serviceable SSC. We 

are proposing this AD to detect and 

correct loss of the hydraulic locking 

function during take-off, which, in 

combination with one inoperative 

engine, could result in reduced 

controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by May 29, 2014. 

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 2013–0251 

dated October 15, 2013; Correction 

dated October 16, 2013 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

During post-flight maintenance checks 

accomplished on an A330 and on an A340 

airplane, it was identified that seven spoiler 

servo-controls MZ series had lost their 

hydraulic locking function. The results of the 

subsequent technical investigation 

accomplished in-shop by the part supplier 

confirmed the system failure was due to a 

sheared seal on the blocking valve, ensuring 

the blocking function of the spoiler. It is 

suspected that the seal damage may have 

occurred during accomplishment of a 

modification to fit a new design of 

maintenance cover on wing, required by 

EASA AD 2008–0160 [(http://

ad.easa.europa.eu/blob/easa_ad_2008_

0160.pdf/AD_2008-0160)], [which 

corresponds to FAA AD 2009–18–20, 

Amendment 39–16017 (74 FR 46313, 

September 9, 2009)]. 

This condition, if not detected and 

corrected, in combination with one engine 

inoperative at take-off, could result in 

reduced control of the aeroplane. 

Prompted by these findings, Airbus issued 

All Operators Telex (AOT) A330–27A3185 

and AOT A340–27A4181 to request a onetime operational test of the Hydraulic 

Locking Function for aeroplanes on which 

MZ type Spoiler Servo Control (SSC) Part 

Number (P/N) MZ4339390–12 or P/N 

MZ4306000–12 are fitted, and EASA issued 

AD 2012–0009 http://ad.easa.europa.eu/

blob/easa_ad_2012_0009.pdf/AD_2012-0009 

[which corresponds to FAA AD 2012–25–10, 

Amendment 39–17291 (77 FR 76228, 

December 27, 2012)] to require 

accomplishment of this test. 

Since that [EASA] AD was issued, Airbus 

re-assessed the situation and determined that 

it is necessary to introduce repetitive 

inspections [operational tests] of the SSC, 

irrespective of SSC type. Airbus issued three 

SBs for those repetitive inspections 

[operational tests] on all A330, A340, and 

A340–500/600 aeroplanes. 

For the reason described above, this 

[EASA] AD requires repetitive operational 

tests of the hydraulic locking function of the 

SSC installed on the Blue and Yellow 

hydraulic circuits, irrespective of the SSC 

type, and, depending on test results, 

replacement of the SSC. 

This [EASA] AD has been republished to 

correct the date of publication. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating it in Docket No. FAA– 

2014–0228. 

Relevant Service Information 

Airbus has issued the following 

service information. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

• Airbus Mandatory Service Bulletin 

A330–27–3195, dated December 7, 

2012. 

• Airbus Mandatory Service Bulletin 

A340–27–4188, dated December 7, 

2012. 

• Airbus Mandatory Service Bulletin 

A340–27–5059, dated April 10, 2013. 

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. 

Costs of Compliance 

We estimate that this proposed AD 

affects about 77 airplanes of U.S. 

registry. 

We also estimate that it would take 

about 6 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 

$39,270, or $510 per product. 

We estimate that it would take about 

3 work-hours per product to do any 

necessary SSC replacement that would 

be required based on the results of the 

proposed operational test. Required 

parts would cost about $35,000 per SSC. 

We have no way of determining the 

number of aircraft that might need these 

replacements. 

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 proposed 

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); 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 79, No. 71 / Monday, April 14, 2014 / Proposed Rules 20841 

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.
