SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Dassault Aviation Model 

MYSTERE-FALCON 900 airplanes. The 

NPRM published in the Federal 

Register on April 30, 2018 (83 FR 

18753). The NPRM was prompted by a 

determination that more restrictive 

maintenance requirements and 

airworthiness limitations are necessary. 

The NPRM proposed to require revising 

the maintenance or inspection program, 

as applicable, to incorporate new and 

more restrictive maintenance 

requirements and airworthiness 

limitations. We are issuing this AD to 

prevent reduced structural integrity of 

the airplane. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2018–0027, 

dated January 30, 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 900 airplanes. The 

MCAI states: 

The airworthiness limitations and 

certification maintenance instructions for the 

Dassault Myste`re-Falcon 900 aeroplanes, 

which are approved by EASA, are currently 

defined and published in the Dassault 

Myste`re-Falcon 900 [Airplane Maintenance 

Manual] AMM chapter 5–40. These 

instructions have been identified as 

mandatory for continued airworthiness. 

Failure to accomplish these instructions 

could result in an unsafe condition [i.e., 

reduced structural integrity of the airplane]. 

Consequently, EASA issued AD 2016–0127 

[which corresponds to FAA AD 2017–19–03 

Amendment 39–19033 (82 FR 43166, 

September 14, 2017) (‘‘AD 2017–19–03’’)] to 

require accomplishment of the maintenance 

tasks, and implementation of the 

airworthiness limitations, as specified in 

Dassault Myste`re-Falcon 900 AMM chapter 

5–40 Revision 22. 

Since that [EASA] AD was issued, Dassault 

issued Revision 23 of the Dassault Myste`reFalcon 900 AMM chapter 5–40, which 

introduces new and more restrictive 

maintenance requirements and/or 

airworthiness limitations. 

For the reason described above, this 

[EASA] AD retains the requirements of EASA 

AD 2016–0127, which is superseded, and 

requires accomplishment of the actions 

specified in Revision 23 of the Dassault 

Myste`re-Falcon 900 AMM chapter 5–40 

* * *.

AD docket on the internet at http://

and locating Docket No. FAA–2018– 

0359. 

Comments 

We gave the public the opportunity to 

participate in developing this final rule. 

We received no comments on the NPRM 

or on the determination of the cost to 

the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this 

final rule as proposed, except for minor 

editorial changes. We have determined 

that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

Dassault Aviation has issued Chapter 

5–40, Airworthiness Limitations, 

Revision 23, dated September 2017, of 

the Dassault Aviation Falcon 900 

Maintenance Manual. This service 

information describes procedures, 

maintenance tasks, and airworthiness 

limitations specified in the 

Airworthiness Limitations Section 

(ALS) of the AMM. 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. 

Costs of Compliance 

We estimate that this AD affects 65 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this 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 


daltland on DSKBBV9HB2PROD with RULES
47814 Federal Register / Vol. 83, No. 184 / Friday, September 21, 2018 / Rules and Regulations 

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 perairplane 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 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 and associated appliances to 

the Director of the System Oversight 

Division. 

Regulatory Findings 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 that this AD: 

(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.

SUPPLEMENTARY INFORMATION: 

Discussion 

On February 21, 2018, at 83 FR 7423, 

the Federal Register published our 

notice of proposed rulemaking (NPRM), 

which proposed to amend 14 CFR part 

39 by adding an AD that would apply 

to AgustaWestland S.p.A (now 

Leonardo) Model AW189 helicopters 

with tail assembly part number (P/N) 

8G5350A00131 installed. The NPRM 

proposed to require inspecting the TGB 

fitting for a crack. The proposed 

requirements were intended to detect a 

crack on a TGB fitting, which could 

reduce the tail assembly’s ability to 

sustain loads from the TGB and the tail 

rotor and result in loss of helicopter 

control. 

The NPRM was prompted by AD No. 

2016–0177, dated September 8, 2016, 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union, to correct an unsafe 

condition for Leonardo (formerly 

Finmeccanica S.p.A. and 

AgustaWestland S.p.A.) Model AW189 

helicopters with a tail assembly P/N 

8G5350A00131. EASA advises that a 

crack was detected on the TGB fitting P/ 

N 4F5350A04152 during a scheduled 

inspection of an AW189 helicopter. 

EASA advises that this condition, if not 

detected and corrected, could lead to 

crack propagation up to a critical length. 

This condition could reduce the 

assembly’s ability to sustain loads from 

the TGB and tail rotor, possibly 

resulting to reduced helicopter control. 

The EASA AD consequently requires 

repetitive inspections of the fitting and 

replacing the fitting, depending on the 

inspections’ outcome. EASA considers 

these actions to be interim and that 

further AD action may follow. 

After the NPRM was published, the 

FAA updated AgustaWestland S.p.A’s 

(AgustaWestland) name to 

Finmeccanica S.p.A. and then to 

Leonardo on its FAA type certificate. 

This name change is reflected in this 

AD.
