13924 Federal Register / Vol. 76, No. 50 / Tuesday, March 15, 2011 / Proposed Rules 

(EASA) Airworthiness Directive 2010–0159, 

dated August 3, 2010, specifies revising the 

maintenance program to include limitations, 

doing certain repetitive actions (e.g., 

inspections), and/or maintaining CDCCLs, 

this AD only requires the revision. Requiring 

a revision of the maintenance program, rather 

than requiring individual repetitive actions 

and/or maintaining CDCCLs, requires 

operators to record AD compliance only at 

the time the revision is made. Repetitive 

actions and/or maintaining CDCCLs specified 

in the airworthiness limitations must be 

complied with in accordance with 14 CFR 

91.403(c). 

Other FAA AD Provisions 

(l) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, Transport Airplane 

Directorate, FAA, has the authority to 

approve AMOCs for this AD, if requested 

using the procedures found in 14 CFR 39.19. 

In accordance with 14 CFR 39.19, send your 

request to your principal inspector or local 

Flight Standards District Office, as 

appropriate. If sending information directly 

to the International Branch, send it 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: 

Time between overhaul (TBO) of DC [direct 

current] generator bearings is set at 1 000 

flight hours (FH) in the airworthiness 

limitations section of the Falcon 7X Aircraft 

Maintenance Manual Chapter 5.40. 

In service report has shown that the 

bearing current design cannot sustain the 

current TBO. * * * 

* * * * * 

Failure to comply with those revised 

maintenance tasks could constitute an unsafe 

condition. 

Failure of the DC generator bearings 

could lead to loss of the generator and 

potential loss of electrical power to 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. 

DATES: We must receive comments on 

this proposed AD by April 29, 2011. 

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 2009–0254, 

dated December 1, 2009 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

mstockstill on DSKH9S0YB1PROD with PROPOSALS

Federal Register / Vol. 76, No. 50 / Tuesday, March 15, 2011 / Proposed Rules 13925 

Time between overhaul (TBO) of DC [direct 

current] generator bearings is set at 1,000 

flight hours (FH) in the airworthiness 

limitations section of the Falcon 7X Aircraft 

Maintenance Manual Chapter 5.40. 

In service report has shown that the 

bearing current design cannot sustain the 

current TBO. In order to prevent 

unscheduled removal of DC generators, TBO 

is reduced down to 650 FH. 

This change is expected to be introduced 

in the next scheduled revision of Chapter 

5.40 of Falcon 7X Aircraft Maintenance 

Manual. 

The purpose of this AD is to require 

accomplishment of the more restrictive 

maximum time limits for DC generators P/N 

30089–004 or 30089–005. 

Failure to comply with those revised 

maintenance tasks could constitute an unsafe 

condition. 

Failure of the DC generator bearings 

could lead to loss of the generator and 

potential loss of electrical power to the 

fly-by-wire system and subsequent loss 

of control of the airplane. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket. 

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–2011– 

0222; Directorate Identifier 2010–NM– 

056–AD. 

Comments Due Date 

(a) We must receive comments by April 29, 

2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Dassault-Aviation 

Model FALCON 7X airplanes, all serial 

numbers, equipped with DC generators 

having part number (P/N) 30089–004 or 

30089–005; certificated in any category. 

Note 1: This AD requires revisions to 

certain operator maintenance documents to 

include new actions (e.g., inspections). 

Compliance with these actions is required by 

14 CFR 91.403(c). For airplanes that have 

been previously modified, altered, or 

repaired in the areas addressed by this AD, 

the operator may not be able to accomplish 

the actions described in the revisions. In this 

situation, to comply with 14 CFR 91.403(C), 

the operator must request approval of an 

alternative method of compliance (AMOC) 

according to paragraph (j) of this AD. The 

request should include a description of 

changes to the required actions that will 

ensure the continued operational safety of 

the airplane. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 05. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

Time between overhaul (TBO) of DC [direct 

current] generator bearings is set at 1,000 

flight hours (FH) in the airworthiness 

limitations section of the Falcon 7X Aircraft 

Maintenance Manual Chapter 5.40. 

In service report has shown that the 

bearing current design cannot sustain the 

current TBO. * * * 

* * * * * 

Failure to comply with those revised 

maintenance tasks could constitute an unsafe 

condition. 

Failure of the DC generator bearings could 

lead to loss of the generator and potential 

loss of electrical power to the fly-by-wire 

system and subsequent loss of control of the 

airplane.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Model DC–8–11, DC–8–12, DC–8–21, 

DC–8–31, DC–8–32, DC–8–33, DC–8–41, 

DC–8–42, and DC–8–43 airplanes, DC–

DC–8F–55 airplanes, DC–8–60 series 

airplanes, DC–8–60F series airplanes, 

DC–8–70 series airplanes, and DC–8– 

70F series airplanes. This proposed AD 

would require repetitive high frequency 

eddy current or repetitive low frequency 

eddy current inspections for cracks on 

the area around certain fasteners of the 

access opening doubler on the left and 

right wing center spar lower cap, and 

repair, if necessary. This proposed AD 

results from reports that cracks in the 

center spar lower cap and, in some 

cases, the web of the spar, have been 

found at stations Xrs=168.00, 

Xrs=251.00, and Xrs=358.00. We are 

proposing this AD to detect and correct 

cracks in the area around certain 

fasteners of the access opening doubler 

on the left and right wing center spar 

lower cap, which could compromise the 

structural integrity of the wing 

structure. 

DATES: We must receive comments on 

this proposed AD by April 29, 2011.
