AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This 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: 

In 2005 a lateral runway excursion 

occurred on an A320 aircraft. Such 

excursions are classified as hazardous, with 

a large reduction in safety margins. 

Investigation has shown that the aircraft 

landed with the nose wheels rotated nearly 

20 degrees from center. During subsequent 

tests on the removed BSCU [Braking and 

Steering Control Unit], a BSCU hardware 

failure was found, affecting the monitoring 

function, including the system 

reconfiguration management, and leading to 

a runaway of [the] Nose Wheel Steering 

[uncommanded steering]. 

* * * * * 

The unsafe condition is an 

uncommanded steering condition 

during takeoff or landing, which could 

result in departure of the airplane from 

the runway. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective 

August 25, 2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 25, 2009.

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 January 7, 2009 (74 FR 664). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

In 2005 a lateral runway excursion 

occurred on an A320 aircraft. Such 

excursions are classified as hazardous, with 

a large reduction in safety margins. 

Investigation has shown that the aircraft 

landed with the nose wheels rotated nearly 

20 degrees from center. During subsequent 

tests on the removed BSCU [Braking and 

Steering Control Unit], a BSCU hardware 

failure was found, affecting the monitoring 

function, including the system 

reconfiguration management, and leading to 

a runaway of [the] Nose Wheel Steering 

[uncommanded steering]. 

DGAC [Direction Ge ́ne ́rale de l’Aviation 

Civile] Airworthiness Directive (AD) F–1992– 

117–025(B), Revision 1 [which corresponds 

to FAA AD 94–24–07], mandated the BSCU 

upgrade in order to improve the steering 

logic, but this modification has shown not to 

be sufficient to address the identified failure 

mechanism. 

A software modification is now 

implemented in BSCU standard 10 which 

improves the system reconfiguration 

management when this failure mechanism is 

detected. 

BSCU standard 10 also includes other 

improvements—as detailed in the associated 

Service Bulletin. 

This AD therefore mandates the 

modification or replacement of the BSCU 

standard 7, 9 or 9.1, by the BSCU standard 

10. 

The unsafe condition is an 

uncommanded steering condition 

during takeoff or landing, which could 

result in departure of the airplane from 

the runway. The corrective action also 

includes replacement of certain 

DUNLOP tires that are not compatible 

with BSCU standard 10. 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. 

Support for the AD 

JetBlue Airways Corporation supports 

the actions specified in the NPRM. 

Request To Relocate Certain Language 

Airbus suggests that we relocate the 

following sentence in the Reason 

section: ‘‘An uncommanded steering 

condition during takeoff or landing 

could result in departure of the airplane 

from the runway.’’ Airbus states that 

relocating that sentence away from the 

previous sentence, which addresses 

replacing tires, would avoid 

misinterpretation by association. 

We acknowledge the Airbus comment 

and we have relocated the subject 

sentence and clarified that it is the 

statement of the unsafe condition in 

both the Discussion and Reason sections 

of this AD. 

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 change described previously. 

We determined that this change will not 

increase the economic burden on any 

operator or increase the scope of the AD. 

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 required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

591 products of U.S. registry. We also 

estimate that it will take about 3 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $80 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 $141,840, or 

$240 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 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); 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 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

or by Airbus Service Bulletin A320–32–1254 

in service. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 32: Landing gear. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

In 2005 a lateral runway excursion 

occurred on an A320 aircraft. Such 

excursions are classified as hazardous, with 

a large reduction in safety margins. 

Investigation has shown that the aircraft 

landed with the nose wheels rotated nearly 

20 degrees from center. During subsequent 

tests on the removed BSCU [Braking and 

Steering Control Unit], a BSCU hardware 

failure was found, affecting the monitoring 

function, including the system 

reconfiguration management, and leading to 

a runaway of [the] Nose Wheel Steering 

[uncommanded steering]. 

DGAC [Direction Ge ́ne ́rale de l’Aviation 

Civile] Airworthiness Directive (AD) F–1992– 

117–025(B), Revision 1 [which corresponds 

to FAA AD 94–24–07], mandated the BSCU 

upgrade in order to improve the steering 

logic, but this modification has shown not to 

be sufficient to address the identified failure 

mechanism. 

A software modification is now 

implemented in BSCU standard 10 which 

improves the system reconfiguration 

management when this failure mechanism is 

detected. 

BSCU standard 10 also includes other 

improvements—as detailed in the associated 

Service Bulletin. 

This AD therefore mandates the 

modification or replacement of the BSCU 

standard 7, 9 or 9.1, by the BSCU standard 

10. 

The unsafe condition is an uncommanded 

steering condition during takeoff or landing, 

which could result in departure of the 

airplane from the runway. The corrective 

action also includes replacement of certain 

DUNLOP tires that are not compatible with 

BSCU standard 10. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) Within 18 months after the effective 

date of this AD: Modify or replace the BSCU 

in accordance with the Accomplishment 

Instructions of Airbus Mandatory Service 

Bulletin A320–32–1336, Revision 01, dated 

January 10, 2008; and inspect the airplane to 

determine if DUNLOP tires 46x16–20 having 

part number (P/N) 11659 T or 11661 T are 

installed. If those tires are installed, before 

further flight, replace with acceptable tires 

using a method approved by either the 

Manager, International Branch, ANM–116, 

Transport Airplane Directorate, FAA; or the 

European Aviation Safety Agency (EASA) (or 

its delegated agent). Accomplishment of the 

applicable requirements in this paragraph 

terminates the requirements of AD 94–24–07, 

amendment 39–9080. 

(2) Previous accomplishment of the 

modification or replacement of the BSCU 

before the effective date of this AD in 

accordance with Airbus Mandatory Service 

Bulletin A320–32–1336, dated September 19, 

2007, meets the requirements of paragraph 

(f)(1) of this AD. 

FAA AD Differences 

Note 1: This AD differs from the MCAI 

and/or service information as follows: 

Although the MCAI and service information 

do not provide procedures for replacing the 

tires as specified in paragraph (f)(1) of this 

AD, this AD requires that you replace the 

tires using a method approved by either the 

Manager, International Branch, ANM–116, 

FAA, or the EASA (or its delegated agent). 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19. Send 

information to ATTN: Tim Dulin, Aerospace 

Engineer, International Branch, ANM–116, 

Transport Airplane Directorate, FAA, 1601 

Lind Avenue, SW., Renton, Washington 

98057–3356; telephone (425) 227–2141; fax 

(425) 227–1149. Before using any approved 

AMOC on any airplane to which the AMOC 

applies, notify your appropriate principal 

inspector (PI) in the FAA Flight Standards 

District Office (FSDO), or lacking a PI, your 

local FSDO. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, under the 

provisions of the Paperwork Reduction Act, 

the Office of Management and Budget (OMB) 

has approved the information collection 

requirements and has assigned OMB Control 

Number 2120–0056.

Airworthiness Directives; Airbus Model 

A310 Series Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD), 

which applies to certain Airbus Model 

A310 series airplanes. That AD 

currently requires repetitive inspections 

of the fuselage skin to detect corrosion 

or fatigue cracking around and under 

the chafing plates of the wing root; 

repetitive inspections for fatigue 

cracking of frame 39, stringer 35; and 

corrective actions if necessary. The 

existing AD also provides for an 

optional terminating action for certain 

repetitive inspections, except for certain 

areas where corrosion was detected and 

reworked. This new AD reduces the 

intervals for accomplishing repetitive 

inspections in a certain area. This AD 

results from mandatory continuing 

airworthiness information originated by 

an aviation authority of another country 

to identify and correct an unsafe 

condition on an aviation product. We 

are issuing this AD to detect and correct 

fatigue cracks and corrosion around and 

under the chafing plates of the wing 

root, which could result in reduced 

structural integrity of the airplane.

SUPPLEMENTARY INFORMATION: 

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that 

supersedes AD 2004–14–06, amendment 

39–13715 (69 FR 41401, July 9, 2004). 

The existing AD applies to certain 

Airbus Model A310 series airplanes. 

That NPRM was published in the 

Federal Register on November 13, 2008 

(73 FR 67110). That NPRM proposed to 

continue to require repetitive 

inspections of the fuselage skin to detect 

corrosion or fatigue cracking around and 

under the chafing plates of the wing 

root; repetitive inspections for fatigue 

cracking of frame 39, stringer 35; and 

corrective actions if necessary. That 

NPRM also proposed to continue to 

provide for an optional terminating 

action for certain repetitive inspections, 

except for certain areas where corrosion 

was detected and reworked. In addition, 

that NPRM proposed to reduce the 

intervals for accomplishing the 

repetitive inspections in a certain area. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comment that has been 

received on the NPRM. FedEx supports 

the NPRM. 

Revisions to Paragraphs (f), (h), (i), and 

(j) of This AD 

We have revised paragraph (h) of this 

AD to give credit for actions done in 

accordance with Airbus Service Bulletin 

A310–53–2070, Revision 1, dated 

September 23, 1996. We also added 

Airbus Service Bulletin A310–53–2069, 

Revision 06, dated May 22, 2007, as an 

acceptable source of service information 

for compliance with the requirements of 

paragraphs (f) and (i) of this AD. We 

have also revised paragraph (j) of this 

AD to include a new Table 1 to specify 

the number, revision, and date of each 

service bulletin for which no reporting 

is required. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We also determined that these changes 

will not increase the economic burden 

on any operator or increase the scope of 

the AD. 

Costs of Compliance 

This AD affects about 69 Model A310 

series airplanes of U.S. registry. The 

actions that are required by AD 2004– 

14–06 and retained in this AD take 

about 68 work hours per airplane, at an 

average labor rate of $80 per work hour. 

Based on these figures, the estimated 

cost of the currently required actions is 

$375,360, or $5,440 per airplane, per 

inspection cycle. 

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 have determined that this AD will 

not have federalism implications under
