FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: No 

differences. 

Other FAA AD Provisions 

(j) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, New York Aircraft 

Certification Office, ANE–170, 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:

Airworthiness Directives; DassaultAviation Model FALCON 7X Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: 

A design review has revealed a potential 

dormant failure of the Ram Air Turbine 

(RAT) heating system. If this failure occurs, 

it could lead to the freezing of the RAT 

mechanism and the consequent nondeployment of the RAT when needed. 

* * * * * 

Non-deployment of the RAT could 

result in insufficient electrical power to 

operate the fly-by-wire system, and

subsequent loss of control of the 

airplane. The proposed AD would 

require actions that are intended to 

address the unsafe condition described 

in the MCAI.

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 2010–0033, 

dated March 3, 2010 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

A design review has revealed a potential 

dormant failure of the Ram Air Turbine 

(RAT) heating system. If this failure occurs, 

it could lead to the freezing of the RAT 

mechanism and the consequent nondeployment of the RAT when needed. 

The purpose of this AD is to require a 

repetitive functional test of the RAT heater 

* * *. 

Non-deployment of the RAT could 

result in insufficient electrical power to 

operate the fly-by-wire system, and 

subsequent loss of control of the 

airplane. The corrective action is 

repairing 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). You may obtain 

further information by examining the 

MCAI in the AD docket. 

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. 

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 proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a Note within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 21 products of U.S. registry. 

We also estimate that it would take 

about 1 work-hour 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 

$1,785, or $85 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 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); 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.

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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: 

Dassault-Aviation: Docket No. FAA–2010– 

1306; Directorate Identifier 2010–NM– 

112–AD. 

Comments Due Date 

(a) We must receive comments by February 

22, 2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Dassault-Aviation 

Model FALCON 7X airplanes, certificated in 

any category, all serial numbers. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 24: Electrical power. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

A design review has revealed a potential 

dormant failure of the Ram Air Turbine 

(RAT) heating system. If this failure occurs, 

it could lead to the freezing of the RAT 

mechanism and the consequent nondeployment of the RAT when needed. 

* * * * * 

Non-deployment of the RAT could result in 

insufficient electrical power to operate the 

fly-by-wire system, and subsequent loss of 

control of the airplane. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Actions 

(g) At the applicable times specified in 

paragraph (g)(1) or (g)(2) of this AD, do a 

functional test of the RAT heater 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). Repeat the functional test of 

the RAT heater thereafter at the applicable 

time specified in paragraph (g)(1) or (g)(2) of 

this AD. If any functional test fails, before 

further flight, repair using a method 

approved by either the Manager, 

International Branch, ANM–116, Transport 

Airplane Directorate, FAA; or EASA (or its 

delegated agent). 

(1) For Falcon 7X airplanes on which 

modification M0305 has not been done and 

on which Dassault Service Bulletin 7X–018, 

dated March 6, 2009, has not been done: 

Within 650 flight hours after the effective 

date of this AD, do a functional test of the 

RAT heater and repeat the functional test of 

the RAT heater thereafter at intervals not to 

exceed 650 flight hours. 

(2) For Falcon 7X airplanes on which 

modification M0305 has been done or on 

which Dassault Service Bulletin 7X–018, 

dated March 6, 2009, has been done: Within 

1,900 flight hours after the effective date of 

this AD or after modification M0305 or 

Dassault Service Bulletin 7X–018, dated 

March 6, 2009, has been done, whichever 

occurs later, do a functional test of the RAT 

heater: Repeat the functional test of the RAT 

heater thereafter at intervals not to exceed 

1,900 flight hours. 

Note 1: Additional guidance for doing the 

functional test of the RAT heater required by 

paragraph (g) of this AD can be found in Task 

24–50–25–720–801, Functional Test of the 

RAT Heater, dated January 16, 2009, of the 

Dassault Falcon 7X Aircraft Maintenance 

Manual (AMM). 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 

(1) The MCAI provides an option of 

inserting the MCAI into the Falcon 7X AMM 

Chapter 5–40, pending publication of the 

revised AMM Chapter 5–40. This AD does 

not have that option. 

(2) The MCAI requires doing the actions in 

accordance with Maintenance Task 24–50– 

25–720–801, Chapter 5–40, of the Dassault 

Falcon 7X AMM. However, this AD requires 

that the actions be done using a method 

approved by the FAA or EASA (or its 

delegated agent). 

Other FAA AD Provisions 

(h) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, 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: Tom Rodriguez, 

Aerospace Engineer, International Branch, 

ANM–116, Transport Airplane Directorate, 

FAA, 1601 Lind Avenue, SW., Renton, 

Washington 98057–3356; telephone (425) 

227–1137; fax (425) 227–1149. Before using 

any approved AMOC on any airplane to 

which the AMOC applies, notify your 

principal maintenance inspector (PMI) or 

principal avionics inspector (PAI), as 

appropriate, or lacking a principal inspector, 

your local Flight Standards District Office. 

The AMOC approval letter must specifically 

reference this AD. 

(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 FAAapproved 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: A Federal 

agency may not conduct or sponsor, and a 

person is not required to respond to, nor 

shall a person be subject to a penalty for 

failure to comply with a collection of 

information subject to the requirements of 

the Paperwork Reduction Act unless that 

collection of information displays a current 

valid OMB Control Number. The OMB 

Control Number for this information 

collection is 2120–0056. Public reporting for 

this collection of information is estimated to 

be approximately 5 minutes per response, 

including the time for reviewing instructions, 

completing and reviewing the collection of 

information. All responses to this collection 

of information are mandatory. Comments 

concerning the accuracy of this burden and 

suggestions for reducing the burden should 

be directed to the FAA at: 800 Independence
