AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued 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 smoke or fire, which could 

be fanned by oxygen leakage from the 

third crew member oxygen mask box. 

This AD requires actions that are 

intended to address the unsafe 

condition described in the MCAI. 

DATES: This AD becomes effective 

February 9, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of Dassault Service Bulletins F900–366 

and F900EX–277, both dated July 19, 

2006, listed in this AD as of February 9, 

2007.

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 

our technical decision-making 

responsibilities to identify and correct 

unsafe conditions on U.S.-certificated 

products. 

This AD references the MCAI and 

related service information that we 

considered in forming the engineering 

basis to correct the unsafe condition. 

The AD contains text copied from the 

MCAI and for this reason might not 

follow our plain language principles. 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Emergency Airworthiness Directive 

2006–0330–E, dated October 25, 2006 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states 

that a drawing review and further 

associated inspections on aircraft have 

highlighted a potential chafing risk 

between the third crew member oxygen 

mask box, optionally installed in the 

cockpit ceiling, and feeder cables routed 

in the area. This situation, if not 

corrected, could generate smoke or fire, 

which could be fanned by oxygen 

leakage from the box. The MCAI 

requires a modification (application of 

epoxy resin to the oxygen box nuts and 

rivets), after a detailed inspection of the 

feeder cables and wiring for damage and 

correct location and corrective actions 

(repairing the feeder cable, re-routing 

certain wiring, or installing a protective 

plate), if necessary. You may obtain 

further information by examining the 

MCAI in the AD docket. 

Relevant Service Information 

Dassault has issued Service Bulletins 

F900–366 and F900EX–277, both dated 

July 19, 2006. The actions described in 

this service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This 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 issuing this 

AD because we evaluated all the 

information provided by the State of 

Design Authority and determined the 

unsafe condition exists and is likely to 

exist or develop on other products of the 

same type design. 

Differences Between the AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 


ycherry on PROD1PC64 with RULES
3346 Federal Register / Vol. 72, No. 16 / Thursday, January 25, 2007 / Rules and Regulations 

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 FAA policies. 

Any such differences are described in a 

separate paragraph of the AD. These 

requirements take precedence over the 

actions copied from the MCAI. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because the manufacturer has 

identified a potential chafing risk 

between the third crew member oxygen 

mask box, which may optionally be 

installed in the cockpit ceiling, and the 

feeder cables routed in the area. This 

could lead to smoke and fire, which 

could be fanned by oxygen leakage from 

the oxygen mask box. Therefore, we 

determined that notice and opportunity 

for public comment before issuing this 

AD are impracticable and that good 

cause exists for making this amendment 

effective in fewer than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2007–26920; 

Directorate Identifier 2006–NM–244–

AD’’ at the beginning of your comments. 

We specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this 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 AD. 

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 would 

not have federalism implications under 

Executive Order 13132. This 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 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 AD and placed it in the AD docket.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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: 

2007–02–10 Dassault Aviation: 

Amendment 39–14897. Docket No. 

FAA–2007–26920; Directorate Identifier 

2006–NM–244–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective February 9, 2007. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Dassault Model 

Mystere–Falcon 900 airplanes, certificated in 

any category, ranging from serial number 

(s/n) 1 through s/n 202 inclusive, without 

modification M5213 or M5236, and equipped 

with a third crew member passenger-type 

oxygen mask on the cockpit ceiling; and

s/n 1 through s/n 156 inclusive, without 

modification M5213 or M5236, and equipped 

with a third crew member passenger-type 

oxygen mask on the cockpit ceiling. 

Reason 

(d) The mandatory continuing 

airworthiness information (MCAI) states that 

a drawing review and further associated 

inspections on aircraft have highlighted a 

potential chafing risk between the third crew 

member oxygen mask box, optionally 

installed in the cockpit ceiling, and feeder 

cables routed in the area. This situation, if 

not corrected, could generate smoke or fire, 

which could be fanned by oxygen leakage 

from the box. The MCAI requires a 

modification (application of epoxy resin to 

the oxygen box nuts and rivets), after a 

detailed inspection of the feeder cables and 

wiring for damage and correct location and 

corrective actions (repairing the feeder cable, 

re-routing certain wiring, or installing a 

protective plate), if necessary. 

Actions and Compliance 

(e) Unless already done, within one month 

or 30 flight cycles, whichever occurs first, 

after the effective date of this AD: Do a 

modification (application of epoxy resin to 

the oxygen box nuts and rivets), after doing 

a detailed inspection of the feeder cables and 

wiring for damage and correct location and 

all applicable corrective actions (repairing 

the feeder cable, re-routing certain wiring, or 

installing a protective plate), as instructed in 

Dassault Service Bulletin F900–366 or 

F900EX–277, both dated July 19, 2006, as 

applicable. Before further flight, do all 

applicable corrective actions. 

Note 1: The aforementioned service 

bulletins cover Dassault Aviation 

modification M5213.

Airworthiness Directives; Bombardier 

Model DHC–8–400 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 Bombardier 

Model DHC–8–400 series airplanes. 

That AD currently requires revising the 

airplane flight manual (AFM) to advise 

the flightcrew of appropriate procedures 

to follow in the event that a main 

landing gear (MLG) fails to extend 

following a gear-down selection. That 

AD also currently requires repetitive 

replacement of the left and right MLG 

uplock assemblies with new assemblies; 

and an inspection of the left and right 

MLG uplock rollers for the presence of 

an inner low friction liner, and 

corrective actions if necessary. This new 

AD revises the requirement for replacing 

the left and right MLG uplock 

assemblies by allowing replacement 

with alternative parts. For a certain 

MLG uplock assembly, this new AD 

requires repetitive inspections of the 

uplock hatch lower jaw for the presence 

of a wear groove and replacement with 

an improved part if necessary. For a 

certain MLG uplock assembly, this new 

AD requires repetitive inspections of the 

uplock roller to ensure that it rotates 

freely and replacement with a new part 

if necessary. This new AD allows 

optional replacement of the left and 

right MLG uplock assemblies with 

improved parts, which ends the 

requirements of the AFM revision and 

repetitive replacement and inspections. 

This new AD removes airplanes from 

the applicability. This AD results from 

development of a terminating action. 

We are issuing this AD to ensure that 

the flightcrew has the procedures 

necessary to address failure of an MLG 

to extend following a gear-down 

selection; and to detect and correct such 

failure, which could result in a gear-up 

landing and possible injury to 

passengers and crew. 

DATES: This AD becomes effective 

March 1, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of March 1, 2007. 

On April 23, 2002 (67 FR 19101, April 

18, 2002), the Director of the Federal 

Register approved the incorporation by 

reference of Bombardier DHC–8 Alert 

Service Bulletin A84–32–15, dated 

February 4, 2002.

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that 

supersedes AD 2002–08–05, amendment 

39–12713 (67 FR 19101, April 18, 2002). 

The existing AD applies to certain 

Bombardier Model DHC–8–400 series 

airplanes. That NPRM was published in 

the Federal Register on October 13, 

2006 (71 FR 60450). That NPRM 

proposed to continue to require revising 

the airplane flight manual (AFM) to 

advise the flightcrew of appropriate 

procedures to follow in the event that a 

main landing gear (MLG) fails to extend 

following a gear-down selection. That 

NPRM also proposed to continue to 

require repetitive replacement of the left 

and right MLG uplock assemblies with 

new assemblies; and an inspection of 

the left and right MLG uplock rollers for 

the presence of an inner low friction 

liner, and corrective actions if 

necessary. That NPRM also proposed to 

revise the requirement for replacing the 


ycherry on PROD1PC64 with RULES
