20296 Federal Register / Vol. 72, No. 78 / Tuesday April 24, 2007 / Proposed Rules 

(g) For airplanes on which the actions 

described in paragraph (f)(1) of this AD are 

performed, doing the actions described in 

paragraph (f)(2) of this AD is terminating 

action for the requirements of paragraph (f)(1) 

of this AD. Once the initial detailed 

inspection specified in paragraph (f)(2) of 

this AD is performed, the AFM limitation 

and placard required by paragraph (f)(1) of 

this AD may be removed. 

Borescope Inspections 

(h) For airplanes not operated under the 

limitation in paragraph (f)(1) of this AD: 

Before the next 10 flight cycles in which the 

slat anti-icing system is activated after the 

effective date of this AD, do a borescope 

inspection of each flexible hose installed in 

the slat anti-icing system. Do all the 

inspections and any applicable corrective 

action (including replacing the hose with a 

new hose having P/N FAL1005D), by 

accomplishing all of the applicable actions 

specified in the Accomplishment 

Instructions of Dassault Alert Service 

Bulletin F10–A312, Revision 1, dated June 

27, 2005. Any corrective action must be done 

before further flight. Repeat the inspection 

thereafter at intervals not to exceed 10 flight 

cycles in which the slat anti-icing system is 

activated. Doing this inspection terminates 

the repetitive inspection requirements of 

paragraph (f)(2) of this AD. 

(i) For airplanes on which the actions 

described in paragraph (f)(1) of this AD are 

performed, doing the actions described in 

paragraph (h) of this AD is terminating action 

for the requirements of paragraph (f)(1) of 

this AD. Once the initial borescope 

inspection specified in paragraph (h) of this 

AD is performed, the AFM limitation and 

placard required by paragraph (f)(1) of this 

AD may be removed. 

AFM Revision 

(j) For airplanes not operated under the 

limitation in paragraph (f)(1) of this AD: 

Before further flight after the effective date of 

this AD, revise the Limitations section of the 

Dassault Aviation Falcon 10 AFM, to include 

the following information. 

‘‘After each flight in which the slat anti-ice 

system is activated, inform maintenance.’’

The AFM revision may be done by inserting 

a copy of this AD into the AFM. 

Note 3: When a statement identical to that 

in paragraph (j)(1) of this AD has been 

included in the general revision of the AFM, 

the general revision may be inserted into the 

AFM, and the copy of this AD may be 

removed from the AFM. 

New Requirements of This AD 

Hose Replacement 

(k) Within 330 flight hours or 7 months 

after the effective date of this AD, whichever 

occurs first: Replace the flexible hoses 

installed in the slat anti-icing system with 

new hoses having P/N FAL1007, in 

accordance with the Accomplishment 

Instructions of Dassault Service Bulletin 

F10–313, Revision 1, dated May 10, 2006. 

This replacement terminates the 

requirements of paragraphs (f) through (j) of 

this AD. For airplanes previously operated 

under the limitation in paragraph (f)(1) of 

this AD: When the hoses have been replaced, 

the AFM limitation and placard required by 

paragraph (f)(1) of this AD may be removed. 

Repeat the hose replacement at intervals not 

to exceed 700 flight cycles. 

(l) Replacement of a hose before the 

effective date of this service bulletin in 

accordance with Dassault Service Bulletin 

F10–313, dated August 10, 2005, is 

acceptable for compliance with the 

requirements of paragraph (k) of this AD. 

Alternative Methods of Compliance 

(AMOCs) 

(m)(1) The Manager, International Branch, 

ANM–116, FAA, has the authority to approve 

AMOCs for this AD, if requested in 

accordance with the procedures found in 14 

CFR 39.19. 

(2) Before using any AMOC approved in 

accordance with § 39.19 on any airplane to 

which the AMOC applies, notify the 

appropriate principal inspector in the FAA 

Flight Standards Certificate Holding District 

Office. 

(3) An AMOC approved previously in 

accordance with AD 2005–18–14 is approved 

as an AMOC for the corresponding 

provisions of this AD.

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

It has been determined that the surface 

roughness of the wing stub safety walks 

Series 300, gray color (equals sandpaper grid 

40), installed during production on some 

aeroplane S/Ns, adversely affects the aircraft 

single engine climb performance. 

The proposed AD would require

SUPPLEMENTARY INFORMATION: 

Streamlined Issuance of AD 

The FAA is implementing a new 

process for streamlining the issuance of 

ADs related to MCAI. This streamlined 

process will allow us to adopt MCAI 

safety requirements in a more efficient 

manner and will reduce safety risks to 

the public. This process continues to 

follow all FAA AD issuance processes to 

meet legal, economic, Administrative 

Procedure Act, and Federal Register 

requirements. We also continue to meet 


jlentini on PROD1PC65 with PROPOSAL
Federal Register / Vol. 72, No. 78 / Tuesday April 24, 2007 / Proposed Rules 20297 

our technical decision-making 

responsibilities to identify and correct 

unsafe conditions on U.S.-certificated 

products. 

This proposed AD references the 

MCAI and related service information 

that we considered in forming the 

engineering basis to correct the unsafe 

condition. The proposed AD contains 

text copied from the MCAI and for this 

reason might not follow our plain 

language principles. 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2007–27610; Directorate Identifier 

2007–CE–023–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

dms.dot.gov, including any personal 

information you provide. We will also 

post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

The Austrian Civil Aviation 

Administration (Austro Control), which 

is the airworthiness authority for 

Austria, has issued AD No. A–2005–

003, dated October 21, 2005 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

It has been determined that the surface 

roughness of the wing stub safety walks 

Series 300, gray color (equals sandpaper grid 

40), installed during production on some 

aeroplane S/Ns, adversely affects the aircraft 

single engine climb performance. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

Diamond Aircraft Industries GmbH 

has issued Mandatory Service Bulletin 

No. MSB–42–006/1, dated September 

20, 2005; and Diamond Aircraft 

Airplane Flight Manual Temporary 

Revision Performance Data DA 42 AFM 

TR–MA ̈ M–42–111/a, dated September 

20, 2005. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of the 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 this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This Proposed 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 70 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 $80 per work-hour. Required 

parts would cost about $285 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 costs. 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 the proposed AD on U.S. 

operators to be $25,550, or $365 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.

(i) No wing stub safety walks Series 300 

(equals sandpaper grid 40), gray color, part 

number (P/N) D60–1127–10–51 (no revision 

letter attached) may be installed as a spare 

part on the Model DA 42 airplane. Only 

Diamond Aircraft Industries (DAI) GmbH 

released safety walk P/Ns with a surface 

roughness equal to or finer than sandpaper 

grid 100 are approved for installation as 

spare parts. 

(ii) Diamond Aircraft Airplane Flight 

Manual Temporary Revision Performance 

Data DA 42 AFM TR–MA ̈ M–42–111/a, dated 

September 20, 2005, Revision 3 to the AFM, 

or any future revision that incorporates the 

same information, must remain part of 

Diamond Aircraft Industries GmbH Aircraft 

Airplane Flight Manual DA 42, Doc. 7.01.05–

E. 

FAA AD Differences 

Note: This AD differs from the MCAI and/ 

or service information as follows: 

(1) The MCAI and service bulletin require 

the insertion of Diamond Aircraft Airplane 

Flight Manual Temporary Revision 

Performance Data DA 42 AFM TR–MA ̈ M–42–

111/a, dated September 20, 2005, Revision 3 

to the Airplane Flight Manual, or any future 

revision that incorporates the same 

information into the Diamond Aircraft 

Industries GmbH Aircraft Airplane Flight 

Manual DA 42, Doc. 7.01.05–E, immediately 

upon receipt. We consider immediately upon 

receipt as an urgent safety of flight 

compliance time, and we do not consider this 

unsafe condition to be an urgent safety of 

flight condition. Because we do not consider 

this unsafe condition to be an urgent safety 

of flight condition, we issued this action 

through the normal notice of proposed 

rulemaking (NPRM) AD process. The time of 

60 days after the effective date of this AD is 

an adequate compliance for this AD action 

and met the FAA requirements of an NPRM 

followed by a final rule. 

(2) Paragraphs A)i) and B)i) of the MCAI, 

state to assure that AFM TR–MAM–42–103, 

distributed with DAI MSB42–005, is inserted 

into AFM Doc. 7.01.05–E, rev. 2 or earlier 

revision. This AFM requirement was for an 

MCAI that the United States did not take AD 

action on. The action is no longer necessary 

when the actions proposed in this NPRM are 

done. Therefore, the action is not being 

mandated in the U.S. AD action. 

(3) The MCAI references revision 2 of the 

AFM. However, the current revision level of 

the AFM is revision 3. The FAA AD 

references revision 3. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Standards Staff, 

FAA, ATTN: Sarjapur Nagarajan, Aerospace 

Engineer, FAA, Small Airplane Directorate, 

901 Locust, Room 301, Kansas City, Missouri 

64106; telephone: (816) 329–4145; fax: (816) 

329–4090, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19. 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 

(44 U.S.C. 3501 et seq.), the Office of 

Management and Budget (OMB) has 

approved the information collection 

requirements and has assigned OMB Control 

Number 2120–0056.

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: 

EASA EAD 2006–0072–E was issued on 

31st March 2006 following a further failure 

of the forward support of the Main Wing 

Outboard Flap (MWOF), caused by corrosion. 

This condition, if not corrected, may cause 

surface twisting during deployment at 

landing. The analysis of that event 

highlighted the need for the reduction of the 

previous inspection interval which was 

mandated by ENAC through AD 2004–523, 

approved by EASA with reference 2004–

12521. 

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI.
