Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2018–0009, 

dated January 15, 2018 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for all Dassault Aviation Model 

MYSTERE–FALCON 200 airplanes. The 

MCAI states: 

The airworthiness limitations for Dassault 

Myste`re Falcon 200 aeroplanes, which are 

approved by EASA, are currently defined and 

published in AMM [aircraft maintenance 

manual] ALS [airworthiness limitations 

section] Chapter 5–40. These instructions 

have been identified as mandatory for 

continued airworthiness. 

Failure to accomplish these instructions 

could result in an unsafe condition. 

EASA previously issued AD 2008–0221 

(later corrected), requiring the actions 

described in Dassault Myste`re Falcon 200 

AMM Chapter 5–40 (DMD 18740A) at 

Revision 14. Since that [EASA] AD was 

issued, Dassault published the ALS, 

containing new and/or more restrictive 

maintenance tasks. 

For the reason described above, this 

[EASA] AD takes over the requirements for 

Myste`re Falcon 200 aeroplanes from EASA 

AD 2008–0221 and requires accomplishment 

of the actions specified in the ALS. 

You may examine the MCAI in the 

AD docket on the internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2018– 

0549. 

Related Service Information Under 1 

CFR Part 51 

Dassault Aviation has issued Falcon 

200 Maintenance Manual, 

Airworthiness Limitations, Chapter 5– 

40–00, Revision 17, dated December 20, 

2017. The service information describes 

mandatory maintenance tasks that 

operators must perform at specified 

intervals. This service information is 

reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section. 

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. 

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 proposed 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 for an alternative 

method of compliance according to 

paragraph (i)(1) of this proposed AD. 

The request should include a 

description of changes to the required 

actions that will ensure the continued 

damage tolerance of the affected 

structure. 

Difference Between This Proposed AD 

and the MCAI or Service Information 

The MCAI specifies that if there are 

findings from the airworthiness 

limitations section (ALS) inspection 

tasks, corrective actions must be 

accomplished in accordance with 

Dassault maintenance documentation. 

However, this proposed AD does not 

include that requirement. Operators of 

U.S.-registered airplanes are required by 

general airworthiness and operational 

regulations to perform maintenance 

using methods that are acceptable to the 

FAA. We consider those methods to be 

adequate to address any corrective 

actions necessitated by the findings of 

ALS inspections required by this 

proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 9 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed AD: 

We have determined that revising the 

maintenance or inspection program 

takes an average of 90 work-hours per 

operator, although we recognize that 

this number may vary from operator to 

operator. In the past, we have estimated 

that this action takes 1 work-hour per 

airplane. Since operators incorporate 

maintenance or inspection program 

changes for their affected fleet(s), we 

have determined that a per-operator 

estimate is more accurate than a perVerDate Sep<11>2014 16:34 Jun 21, 2018 Jkt 244001 PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 E:\FR\FM\22JNP1.SGM 22JNP1

airplane estimate. Therefore, we 

estimate the total cost per operator to be 

$7,650 (90 work-hours × $85 per workhour). 

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. 

This proposed AD is issued in 

accordance with authority delegated by 

the Executive Director, Aircraft 

Certification Service, as authorized by 

FAA Order 8000.51C. In accordance 

with that order, issuance of ADs is 

normally a function of the Compliance 

and Airworthiness Division, but during 

this transition period, the Executive 

Director has delegated the authority to 

issue ADs applicable to transport 

category airplanes to the Director of the 

System Oversight Division. 

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); 

3. Will not affect intrastate aviation in 

Alaska; and 

4. 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, Incorporation by reference, 

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 airworthiness 

directive (AD): 

Dassault Aviation: Docket No. FAA–2018– 

0549; Product Identifier 2018–NM–014– 

AD. 

(a) Comments Due Date

(c) Applicability 

This AD applies to all Dassault Aviation 

Model MYSTERE-FALCON 200 airplanes, 

certificated in any category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 05, Time Limits/Maintenance 

Checks. 

(e) Reason 

This AD was prompted by a determination 

that more restrictive maintenance 

requirements and airworthiness limitations 

are necessary. We are issuing this AD to 

address fatigue cracking, damage, and 

corrosion in principal structural elements; 

such fatigue cracking, damage, and corrosion 

could result in reduced structural integrity of 

the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Maintenance or Inspection Program 

Revision 

Within 90 days after the effective date of 

this AD, revise the maintenance or inspection 

program, as applicable, to incorporate Falcon 

200 Maintenance Manual, Airworthiness 

Limitations, Chapter 5–40–00, Revision 17, 

dated December 20, 2017. The initial 

compliance time for accomplishing the 

actions is at the applicable time specified in 

Falcon 200 Maintenance Manual, 

Airworthiness Limitations, Chapter 5–40–00, 

Revision 17, dated December 20, 2017; or 

within 90 days after the effective date of this 

AD; whichever occurs later. 

(h) No Alternative Actions or Intervals 

After the maintenance or inspection 

program has been revised as required by 

paragraph (g) of this AD, no alternative 

actions (e.g., inspections) or intervals may be 

used unless the actions or intervals are 

approved as an alternative method of 

compliance (AMOC) in accordance with the 

procedures specified in paragraph (i)(1) of 

this AD. 

(i) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance

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 Section, send it to the 

attention of the person identified in 

paragraph (j)(2) of this AD. Information may 

be emailed to: 9-ANM-116-AMOCREQUESTS@faa.gov. Before using any 

approved AMOC, notify your appropriate 

principal inspector, or lacking a principal 

inspector, the manager of the local flight 

standards district office/certificate holding 

district office. 

(2) Contacting the Manufacturer: For any 

requirement in this AD to obtain corrective 

actions from a manufacturer, the action must 

be accomplished using a method approved 

by the Manager, International Section, 

Transport Standards Branch, FAA; or the

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc., Model DHC–8–400 

series airplanes. This proposed AD was 

prompted by a report of broken Pclamps on the pressure relief line and 

the motive flow line in the left and right 

fuel tanks, and fouling conditions 

between the motive flow line and the 

collector tank partition wall in both fuel 

tanks. This proposed AD would require, 

depending on airplane configuration: 

Increasing the hole size in the collector 

tank partition wall, inspecting the 

motive flow line for damage, and 

replacing the associated grommet and 

motive flow line; replacing the affected 

single nut plate brackets and standoffs 

at the affected stations on the motive 

flow line and pressure relief line; and 

inspecting the motive flow line and vent 

line at certain wing stations, and 

inspecting the fuel tubes, to verify that 

an appropriate clearance has been 

maintained between the fuel tubes and 

their support brackets, and applicable 

corrective actions. We are proposing 

this AD to address the unsafe condition 

on these products. 

DATES: We must receive comments on 

this proposed AD by August 6, 2018.

CF–2017–05R1, dated September 20, 

2017 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for certain 

Bombardier, Inc., Model DHC–8–400 

series airplanes. The MCAI states: 

Some operators have reported broken Pclamps on the pressure relief line and the 

motive flow line in the left and right fuel 

tanks. Fouling conditions were also reported 

to exist between the motive flow line and the 

collector tank partition wall in both fuel 

tanks. These issues affect the integrity of the 

electrical bonding paths throughout the fuel 

lines, which in turn may lead to lightning 

strike induced fuel tank ignition. 

The initial issue of this [Canadian] AD 

mandated design changes that mitigate the 

risk of lightning strike induced fuel tank 

ignition. 

Since the initial issue of this [Canadian] 

AD, Transport Canada has become aware that 

Bombardier (BA) Service Bulletin (SB) 84– 

28–19 Revision A, dated 4 November 2016, 

and the initial issue of BA SB 84–28–19, 

dated 16 August 2016, do not instruct 

operators to support the motive flow line and 

vent line at wing stations ¥371.019 and 

371.019 in the left-hand and right-hand fuel 

tanks, respectively, and do not instruct 

operators to maintain appropriate clearance 

between the fuel tubes and their support 

brackets at wing stations ¥371.019 and 

¥209.019 in the left-hand fuel tank and wing 

stations 371.019 and 209.019 in the righthand fuel tank. Revision 1 of this [Canadian] 

AD introduces Part III, which requires 

operators to inspect and correct the fuel tube 

installation on affected aeroplanes, as 

required, to maintain fuel tube support and 

clearance between the fuel tubes and their 

support brackets. Revision 1 of this 

[Canadian] AD also updates SB references. 

Required actions include, depending 

on airplane configuration, increasing the 

hole size in the collector tank partition 

wall, inspecting the motive flow line for 

damage, and replacing the associated 

grommet and motive flow line; 

replacing the affected single nut plate 

brackets and standoffs at the affected 

stations on the motive flow line and 

pressure relief line; and inspecting the 

motive flow line and vent line at certain 

wing stations, and inspecting the fuel 

tubes, to verify that an appropriate 

clearance has been maintained between 

the fuel tubes and their support 

brackets, and applicable corrective 

actions. Corrective actions include 

reworking the replaced parts. You may
