Airworthiness Directives; Airbus 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Airbus Model A330–200 and A330–300 

series airplanes, and Model A340–200 

and A340–300 series airplanes. This AD 

was prompted by reports of an elevator 

blocked in the down position due to two 

independent failures; first, the inability 

of a servo control to switch to active 

mode because it was not detected by a 

flight control computer; and second, an 

internal hydraulic leak due to the 

deterioration of an O-ring seal on a 

solenoid. This AD requires, depending 

on airplane configuration, modifying 

three flight control primary computers 

(FCPCs); modifying two flight control 

secondary computers (FCSCs); revising 

the airplane flight manual (AFM) to 

include certain information; replacing 

certain O-rings; and checking part 

number and replacing certain O-ring 

seals if needed. We are issuing this AD 

to detect and correct O-rings with 

incorrect part numbers whose 

deterioration could lead to improper 

sealing of solenoid valves; and to correct 

FCPC and FCSC software to allow better 

control of elevator positioning; both 

conditions, if not corrected, could lead 

to the loss of elevator control on takeoff, 

and potentially reduce the 

controllability of the airplane. 

DATES: This AD becomes effective June 

13, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of June 13, 2013.

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 August 14, 2012 (77 FR 

48469). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information (MCAI) 

states: 

This [European Aviation Safety Agency 

(EASA)] AD [2010–0081, dated April 27, 

2010] deals with the two following points: 

• Case of an elevator blocked in down 

position due to two independent failures one 

of which is hidden: 

Each elevator is controlled by two servo 

controls. In normal operation: 

—one servo control in active mode controlled 

by PRIM 1 (Green servo control), 

—one servo control in damping mode 

(Yellow or Blue servo control) monitored 

by PRIM 2. 

Change from active mode to damped mode 

is obtained by means of a mode selector 

which is controlled by two identical solenoid 

valves housed on the servo control. The 

sealing of each solenoid valve is ensured by 

four O-ring seals. 

During pre-flight control checks, the flight 

crew of an A330–200 aeroplane observed that 

one of the elevators was blocked in down 

position, the ECAM [electronic centralized 

aircraft monitor] screen displaying ‘‘F/CTL 

PRIM 1 PITCH FAULT’’. 

This condition was due to two 

independent failures, one of which was 

dormant, which occurred on one of the 

elevators. 

Investigations revealed that the origin of 

the elevator malfunction was due to the 

inability of the Yellow servo control to 

switch to active mode. 

This inability: 

—was caused by an internal hydraulic leak 

due to the deterioration of an O-ring seal 

on a solenoid valve, 


tkelley on DSK3SPTVN1PROD with RULES
27016 Federal Register / Vol. 78, No. 90 / Thursday, May 9, 2013 / Rules and Regulations 

—was not detected by the PRIM 2 computer 

nor announced to the flight crew. 

• Incorrect Part Number (P/N) for solenoid 

valve O-ring seals in IPC [illustrated parts 

catalog]: 

An incorrect O-ring seal P/N in IPC 27–34– 

51–1 could have led to the installation of Oring seals incompatible with the hydraulic 

fluid, causing them to deteriorate. 

These conditions if not detected could lead 

to the loss of elevator [control] on takeoff 

and, potentially reduce the controllability of 

the aeroplane. 

The aim of EASA AD 2007–0009 was to: 

—take over the requirements of AD F–2004– 

158, and 

—require the terminating action for § (1), (2) 

and (4) of this [EASA] AD by introducing 

new capped seals on solenoid valves for 

A330–200 only. 

This new [EASA] AD * * * requires the 

embodiment of the latest software standard 

on the three Flight Control Primary 

Computers (FCPC) and on the two Flight 

Control Secondary Computers (FCSC) [by 

modifying the FCPCs and FCSCs] * * *. 

The modification is accomplished 

either by replacing the FCPCs and 

FCSCs with new FCPCs and FCSCs, or 

by replacing or reprogramming the onboard replaceable modules in the FCPCs 

and FCSCs. Required actions also 

include, depending on airplane 

configuration, the following actions: 

Revising the AFM to include certain 

information; replacing certain O-rings; 

and checking part number and replacing 

certain O-ring seals if needed. You may 

obtain further information by examining 

the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request for Exemption for Later 

Standards of FCPC Software 

Delta Air Lines, Inc. (Delta) requested 

that we revise the NPRM (77 FR 48469, 

August 14, 2012) to provide an 

exemption for later standards of FCPC 

software. Since completing Airbus 

Mandatory Service Bulletin A330–27– 

3148, Revision 01, dated October 9, 

2008, Delta stated that it upgraded FCPC 

software from standard P9/M18 to 

newer standard P11A/M20A as 

specified in Airbus Mandatory Service 

Bulletin A330–27–3176, dated July 26, 

2011. Delta noted that when there are 

significant differences between the 

airspeed sources, the autopilot (AP) and 

the auto-thrust (A/THR) are designed to 

disconnect, and the flight directors (FD) 

bars are automatically removed. Delta 

also noted that if two of the airspeed 

sources then read similar, yet erroneous 

numbers, the AP and A/THR will reengage, and the FD bars will reappear. 

Delta stated that this newer standard 

addresses these safety concerns. 

We agree to revise this AD to allow 

modification of the FCPC with the 

software identified in Airbus Mandatory 

Service Bulletin A330–27–3176, 

Revision 02, dated April 24, 2012, as 

well as the software identified in Airbus 

Mandatory Service Bulletin A330–27– 

3177, dated December 21, 2011; Airbus 

Mandatory Service Bulletin A340–27– 

4174, dated November 21, 2011; and 

Airbus Mandatory Service Bulletin 

A340–27–4162, Revision 01, dated 

September 17, 2012. We have added 

paragraph (o) to this AD to specify that 

modification of the three FCPC with 

new software specified in paragraphs 

(o)(1) through (o)(4) of this AD is 

acceptable for compliance with the 

requirements of paragraph (l) of this AD. 

In addition, we have added new 

paragraph (p)(4) of this AD to give credit 

for performing actions before the 

effective date of this AD using Airbus 

Service Bulletin A330–27–3176, dated 

July 26, 2011; Airbus Mandatory Service 

Bulletin A330–27–3176, Revision 01, 

dated March 27, 2012; and Airbus 

Mandatory Service Bulletin A340–27– 

4162, dated January 10, 2012. 

We are also considering further 

rulemaking that would correspond to 

EASA AD 2011–0199R1, dated February 

17, 2012, to mandate implementation of 

these new FCPC standards. 

Request for Credit for Modification of 

FCPC Software Using Airbus 

Mandatory Service Bulletin A330–27– 

3148, Revision 01, October 9, 2008 

Delta requested that we revise 

paragraph (o)(2) of the NPRM (77 FR 

48469, August 14, 2012) to give credit 

for modification of FCPC software done 

using Airbus Mandatory Service 

Bulletin A330–27–3148, Revision 01, 

dated October 9, 2008. This service 

bulletin is the appropriate source of 

service information for accomplishing 

the actions required by paragraph (l) of 

the NPRM. Delta stated that paragraph 

(o)(2) of the NPRM provides credit, if 

those actions were performed using 

Airbus Service Bulletin A330–27–3144, 

dated April 2, 2009, but there are no 

statements giving credit for 

modifications of the FCPC performed 

using Airbus Mandatory Service 

Bulletin A330–27–3148, Revision 01, 

dated October 9, 2008. 

We disagree with this request to 

revise this AD, but agree to clarify that 

this AD allows for previous 

accomplishment of the modification 

using Airbus Mandatory Service 

Bulletin A330–27–3148, Revision 01, 

dated October 9, 2008. Paragraph (l) of 

this AD mandates modifications of 

FCPC software using current revisions 

of the service information, Airbus 

Service Bulletin A330–27–3144, 

Revision 01, dated July 16, 2009; or 

Airbus Mandatory Service Bulletin 

A330–27–3148, Revision 01, October 9, 

2008. Paragraph (p)(2) of this AD 

(referred to as paragraph (o)(2) in the 

NPRM (77 FR 48469, August 14, 2012)) 

gives credit only for actions performed 

using previous revisions of the service 

information specified in paragraph (l) of 

this AD, i.e., Airbus Mandatory Service 

Bulletin A330–27–3144, dated April 2, 

2009; and Airbus Mandatory Service 

Bulletin A330–27–3148, dated July 17, 

2008. Since paragraph (f) of this AD 

indicates previous accomplishment of 

modifications do not need to be 

repeated, the intent of the comment is 

addressed. No change has been made to 

the AD in this regard. 

Request for Credit for Modification of 

FCSC Software Using Airbus Service 

Bulletin A330–27–3145, Revision 1, 

Dated July 17, 2008 

Delta requested that we revise 

paragraph (o)(3) of the NPRM (77 FR 

48469, August 14, 2012) to give credit 

for modification of the FCSC software 

done using Airbus Mandatory Service 

Bulletin A330–27–3146, Revision 01, 

dated September 3, 2008; and Airbus 

Service Bulletin A330–27–3145, dated 

December 16, 2008. Delta noted these 

service bulletins are referred to as the 

appropriate sources of service 

information for accomplishing the 

actions proposed by paragraph (m) of 

the NPRM. Delta stated that paragraph 

(o)(3) of the NPRM provides credit, if 

those actions were performed using 

Airbus Mandatory Service Bulletin 

A330–27–3146, dated June 1, 2007, but 

pointed out that there are no statements 

giving credit for modifications of the 

FCSC performed using Airbus 

Mandatory Service Bulletin A330–27– 

3146, Revision 01, dated September 3, 

2008. 

We disagree with this request to 

revise this AD but agree to clarify that 

this AD allows for previous 

accomplishment of the modification 

using Airbus Mandatory Service 

Bulletin A330–27–3146, Revision 01, 

dated September 3, 2008; and Airbus 

Service Bulletin A330–27–3145, dated 

December 16, 2008. Paragraph (m) of 

this AD mandates modifications of 

FCSC software using Airbus Mandatory 

Service Bulletin A330–27–3146, 

Revision 01, dated September 3, 2008; 

or Airbus Service Bulletin A330–27– 

3145, dated December 16, 2008. 

Paragraph (p)(3) of this AD (referred to 

as paragraph (o)(3) in the NPRM (77 FR 

48469, August 14, 2012)) gives credit 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 78, No. 90 / Thursday, May 9, 2013 / Rules and Regulations 27017 

only for actions performed using 

previous revisions of the service 

information specified in paragraph (m) 

of this AD, i.e., Airbus Service Bulletin 

A330–27–3146, dated June 1, 2007. 

Since paragraph (f) of this AD indicates 

previous accomplishment of 

modifications do not need to be 

repeated, the intent of the comment is 

addressed. No change has been made to 

the AD in this regard. 

Request for Credit for Installation of 

Modified Servo-Controls Using Airbus 

Service Bulletin A330–27–3134, 

Revision 01, Dated May 12, 2006; and 

Airbus Mandatory Service Bulletin 

A330–27–3136, Revision 1, Dated July 

19, 2006 

Delta requested that we revise 

paragraph (p) of the NPRM (77 FR 

48469, August 14, 2012) to give credit 

for the installation of modified servocontrols done using Airbus Service 

Bulletin A330–27–3134, Revision 01, 

dated May 12, 2006; and Airbus 

Mandatory Service Bulletin A330–27– 

3136, Revision 01, dated July 19, 2006. 

We disagree with this request to 

revise this AD, but agree to clarify that 

this AD allows for previous 

accomplishment of the installation 

using Airbus Service Bulletin A330–27– 

3134, Revision 01, dated May 12, 2006; 

and Airbus Mandatory Service Bulletin 

A330–27–3136, Revision 01, dated July 

19, 2006. Paragraph (q) of this AD 

(referred to as paragraph (p) of the 

NPRM (77 FR 48469, August 14, 2012)) 

provides terminating action for the 

actions required by paragraphs (g), (h), 

and (i) of this AD, if the installation of 

modified servo-controls was using 

Airbus Service Bulletin A330–27–3134, 

Revision 01, dated May 12, 2006; and 

Airbus Mandatory Service Bulletin 

A330–27–3136, Revision 01, dated July 

19, 2006. Since paragraph (f) of this AD 

indicates previous accomplishment of 

the installation not need to be repeated, 

the intent of the comment is addressed. 

No change has been made to the AD in 

this regard. 

Explanation of Change Made to This 

AD 

We have revised paragraph (n) of this 

AD to put the AFM text into Figure 1 

to paragraph (n) of this AD, and 

included reference to the figure in that 

paragraph. This change does not affect 

the intent of that paragraph. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously— 

and minor editorial changes. We have 

determined that these changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

48469, August 14, 2012) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 48469, 

August 14, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

41 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 $85 per work-hour. 

Required parts will cost about $0 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 $17,425, or 

$425 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 that 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); 

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 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,

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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: 

2013–05–08 Airbus: Amendment 39–17380. 

Docket No. FAA–2012–0808; Directorate 

Identifier 2010–NM–170–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective June 13, 2013. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Airbus airplanes, 

certificated in any category, specified in 

paragraphs (c)(1) and (c)(2) of this AD. 

(1) Model A330–201, –202, –203, –223, 

–243, –301, –302, –303, –321, –322, –323,

27018 Federal Register / Vol. 78, No. 90 / Thursday, May 9, 2013 / Rules and Regulations 

–341, –342, and –343 airplanes, all 

manufacturer serial numbers (MSN). 

(2) Model A340–211, –212, –213, –311, 

–312, and –313 airplanes, all MSN. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 27: Flight controls. 

(e) Reason 

This AD was prompted by reports of an 

elevator blocked in the down position due to 

two independent failures; first, the inability 

of a servo control to switch to active mode 

because it was not detected by a flight control 

computer; and second, an internal hydraulic 

leak due to the deterioration of an O-ring seal 

on a solenoid. We are issuing this detect and 

correct O-rings with incorrect part numbers 

whose deterioration could lead to improper 

sealing of solenoid valves; and to correct 

flight control primary computer (FCPC) and 

flight control secondary computer (FCSC) 

software to allow better control of elevator 

positioning; both conditions, if not corrected, 

could lead to the loss of elevator control on 

takeoff, and potentially reduce the 

controllability of the airplane. 

(f) Compliance 

You are responsible for having the actions 

required by this AD performed within the 

compliance times specified, unless the 

actions have already been done. 

(g) Replacement of O-ring Seals for Elevator 

Servo Controls Installed in Damping
