SUPPLEMENTARY INFORMATION: The 

Direction General De L’Aviation Civile 

(DGAC), which is the airworthiness 

authority for France, recently notified us 

that an unsafe condition might exist on 

Turbomeca S.A. Arrius 2F turboshaft 

engines. In addition, on May 13, 2005, 

an uncommanded in-flight engine 

shutdown (IFSD) of an Arrius 2F engine 

resulted in the forced landing of a 

Eurocopter EC120B helicopter in the 

Gulf of Mexico. Investigation of the 

engine found that an interruption of 

engine lubrication due to excessive 

swelling of the check valve O-ring in the 

lubrication unit caused the IFSD. The 

amount of swelling of the O-ring 

depends on the class of oil used, 

standard (STD) or high-thermal stability 

(HTS), and the engine operating time. 

This condition, if not corrected, could 

result in an uncommanded in-flight 

shutdown of the engine, which could 

result in a forced autorotation landing 

and damage to the helicopter. 

Relevant Service Information 

We have reviewed and approved the 

technical contents of Turbomeca Alert 

Service Bulletin (ASB) No. A319 79 

4802, dated June 21, 2005, that 

describes procedures for replacing the 

O-ring on the check valve piston of the 

lubrication unit. The DGAC classified 

this alert service bulletin as mandatory 

and issued AD No. F–2005–122, dated 

July 20, 2005, in order to ensure the 

airworthiness of these Turbomeca S.A. 

Arrius 2F turboshaft engines in France. 

Bilateral Airworthiness Agreement 

This turboshaft engine model is 

manufactured in France, and is type 

certificated for operation in the United 

States under the provisions of section 

21.29 of the Federal Aviation 

Regulations (14 CFR 21.29) and the 

applicable bilateral airworthiness 

agreement. Under this bilateral 

airworthiness agreement, the DGAC 

kept the FAA informed of the situation 

described above. We have examined the 

findings of the DGAC, reviewed all 

available information, and determined 

that AD action is necessary for products 

of this type design that are certificated 

for operation in the United States. 

FAA’s Determination and Requirements 

of This AD 

The unsafe condition described 

previously is likely to exist or develop 

on other Turbomeca S.A. Arrius 2F 

turboshaft engines of the same type 

design. We are issuing this AD to 

prevent an uncommanded in-flight 

shutdown of the engine, which could 

result in a forced autorotation landing 

and damage to the helicopter. This AD 

requires replacing the O-ring on the 

check valve piston in the lubrication 

unit at the following intervals: 

• For engines that use HTS or an 

unknown class oil, within 300 hours 

time-since-new (TSN) or 50 hours after 

the effective date of this AD, whichever 

is later. 

• For engines that use STD class oil, 

within 450 hours TSN or 50 hours after 

the effective date of this AD, whichever 

is later. 

• Thereafter, replace the O-ring 

within 300 hours time-since-last 

replacement (TSR) on engines that use 

HTS class oil or 500 hours TSR on 

engines that use STD class oil. 

You must use the service information 

described previously to perform the 

actions required by this AD. 

FAA’s Determination of the Effective 

Date 

Since an unsafe condition exists that 

requires the immediate adoption of this 

AD, we have found that notice and 

opportunity for public comment before 

issuing this AD are impracticable, and 

that good cause exists for making this 

amendment effective in less than 30 

days. 

Interim Action 

These actions are interim actions and 

we may take further rulemaking actions 

in the future. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment; 

however, we invite you to send us any 

written relevant data, views, or 

arguments regarding this AD. Send your

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 

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 the 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); 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 summary of the costs 

to comply with this AD and placed it in 

the AD Docket.

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Model A330–200, A330–300, 

A340–200, and A340–300 series 

airplanes; and Model A340–541 and 

–642 airplanes. This AD requires 

repetitively resetting the display units 

(DUs) for the electronic instrument 

system (EIS) either by switching them 

off and back on again or by performing 

a complete electrical shutdown of the 

airplane. This AD results from an 

incident in which all of the DUs for the 

EIS went blank simultaneously during 

flight. We are issuing this AD to prevent 

automatic reset of the DUs for the EIS 

during flight and consequent loss of 

data from the DUs, which could reduce 

the ability of the flightcrew to control 

the airplane during adverse flight 

conditions.

SUPPLEMENTARY INFORMATION: 

Discussion 

The Direction Ge ́ne ́rale de l’Aviation 

Civile (DGAC), which is the 

airworthiness authority for France, 

notified us that an unsafe condition may 

exist on certain Airbus Model A330– 

200, A330–300, A340–200, and A340– 

300 series airplanes; and A340–541 and 

–642 airplanes. The DGAC advises of an 

incident that occurred on a Model A330 

series airplane, in which all six of the 

liquid crystal display units (DUs) for the 

electronic instrument system (EIS) 

(which is equipped with the EIS2 

software standard) went blank 

simultaneously during flight. The DUs 

recovered automatically after 

approximately 40 seconds. This 

incident was attributed to an automatic 

reset function of the DUs. (After the DUs 

have been continuously powered for 

more than 6 days, an internal timer 

automatically resets them.) This 

condition, if not corrected, could result 

in loss of data from the DUs, which 

could reduce the ability of the 

flightcrew to control the airplane during 

adverse flight conditions. 

Relevant Service Information 

Airbus has issued All Operator 

Telexes (AOTs) A330–31A3092 (for 

Model A330–200 and –300 series 

airplanes), A340–31A4102 (for Model 

A340–200 and –300 series airplanes), 

and A340–31A5023 (for Model A340– 

541 and –642 airplanes), all dated 

August 1, 2005. The AOTs are effective 

for airplanes of the identified models on 

which the EIS is equipped with the EIS2 

software standard, version L4–1 or L–5. 

The AOTs describe procedures for 

resetting the DUs for the EIS by 

switching them off, waiting 5 seconds or 

longer, then switching the DUs back on 

again. The DGAC mandated the AOTs 

and issued French emergency 

airworthiness directive UF–2005–150, 

dated August 10, 2005, to ensure the 

continued airworthiness of these 

airplanes in France. 

FAA’s Determination and Requirements 

of This AD 

These airplane models are 

manufactured in France and are type 

certificated for operation in the United 

States under the provisions of section 

21.29 of the Federal Aviation 

Regulations (14 CFR 21.29) and the 

applicable bilateral airworthiness 

agreement. Pursuant to this bilateral 

airworthiness agreement, the DGAC has 

kept the FAA informed of the situation 

described above. We have examined the 

DGAC’s findings, evaluated all pertinent 

information, and determined that we 

need to issue an AD for products of this 

type design that are certificated for 

operation in the United States. 

Therefore, we are issuing this AD to 

prevent automatic reset of the DUs for 

the EIS during flight and consequent 

loss of data from the DUs, which could 

reduce the ability of the flightcrew to 

control the airplane during adverse 

flight conditions. This AD requires 

repetitively resetting the DUs for the EIS 

either by accomplishing the actions 

specified in the AOTs described 

previously, or by performing a complete 

electrical shutdown of the airplane. We 

have determined that switching the DUs 

off and back on again may be properly 

performed by flight deck crew (or by 

certificated maintenance personnel) 

because this action does not require 

tools, precision measuring equipment, 

training, or pilot logbook endorsements, 

or the use of or reference to technical 

data that are not contained in the body 

of the AD. 

Interim Action 

We consider this AD interim action. 

The manufacturer is currently 

developing a modification that will 

address the unsafe condition identified 

in this AD. Once this modification is 

developed, approved, and available, we 

may consider additional rulemaking. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this
