notifications of change of prior-dated items that 

only post at 5:00 p.m.; and paper returns of sameday forward items that only post at 5:30 p.m. 

Institutions that are monitored in real time must 

fund the total amount of their commercial ACH 

credit originations in order for the transactions to 

be processed. If the Federal Reserve receives 

commercial ACH credit transactions from 

institutions monitored in real time after the 

scheduled close of the Fedwire Funds Service, 

these transactions will be processed at 12:30 a.m. 

the next business day, or by the ACH deposit 

deadline, whichever is earlier. The Account 

Balance Monitoring System provides intraday 

account information to the Reserve Banks and 

institutions and is used primarily to give authorized 

Reserve Bank personnel a mechanism to control 

and monitor account activity for selected 

institutions. For more information on ACH 

transaction processing, refer to the ACH Settlement 

Day Finality Guide available through the Federal 

Reserve Financial Services Web site at http://

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Dassault Aviation Model FALCON 7X 

airplanes. This AD was prompted by a 

report indicating that, under certain 

operational takeoff conditions, the 

available thrust in relation with the N1 

indication is less than a certified value, 

which could affect the safety margins 

with an engine failure during takeoff. 

This AD requires modifying each engine 

by updating the electronic engine 

control (EEC) software and adjusting the 

engine N1 trim value, and revising the 

airplane flight manual (AFM). We are 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective September 

29, 2017. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 29, 2017.

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 certain Dassault Aviation 

Model FALCON 7X airplanes. The 

NPRM published in the Federal 

Register on May 30, 2017 (82 FR 24603) 

(‘‘the NPRM’’). We are issuing this AD 

to prevent a reduction in available 

engine thrust during certain operational 

takeoff conditions, which could affect 


pmangrum on DSK3GDR082PROD with RULES
Federal Register / Vol. 82, No. 164 / Friday, August 25, 2017 / Rules and Regulations 40475 

the safety margins with an engine 

failure during takeoff and could result 

in reduced control 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 Airworthiness 

Directive 2016–0063, dated March 31, 

2016 (referred to after this as the 

Mandatory Continuing Airworthiness 

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

an unsafe condition for certain Dassault 

Aviation FALCON 7X airplanes. The 

MCAI states: 

A review of the Pratt & Whitney Canada 

(PWC) 307A engine data files has disclosed 

that, under certain operational take-off 

conditions (high altitude runway and low 

temperature), the available thrust in relation 

with N1 indication is less than certified and 

described in the Aircraft Flight Manual 

(AFM). 

This condition, if not corrected, affects the 

safety margins with an engine failure during 

take-off, possibly resulting in reduced control 

of the aeroplane. 

To address this potential unsafe condition, 

PWC developed an interim correction [i.e., 

modifying each engine installed on the 

airplane], to be embodied in service with 

PWC Service Bulletin (SB) 47202, which 

allows augmenting the thrust through a 

general N1-detrimming. Subsequently, PWC 

developed a new Engine Electronic Control 

(EEC) software version, which provides a 

definitive correction of the thrust rating 

deficiency. PWC published SB 47216 that 

provides instructions for in service 

installation of EEC software version 

307A0514. 

Concurrently with these developments, 

Dassault Aviation published SB 7X–287 to 

provide aeroplane modification instructions 

and also revised the performance charts 

relevant to the new thrust rating, available 

with AFM Revision 21 (incorporating 

Temporary Revision CP098). 

For the reasons described above, this 

[EASA] AD requires modification of each 

engine, installation of the new software 

version, and amendment of the applicable 

AFM. 

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–2017– 

0496. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. 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 AD 

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 

correcting 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 

We reviewed Dassault FALCON 7X 

AFM DGT105608, Revision 21, dated 

November 20, 2015, which incorporates 

AFM CP098 (provides performance 

charts relevant to the new thrust rating). 

This AFM describes operating 

limitations, normal/abnormal/ 

emergency operating procedures, and 

performance data and loading 

information. 

We reviewed Dassault Service 

Bulletin 7X–287, also referred to as 287, 

dated January 4, 2016. This service 

information describes procedures for 

modifying each engine installed on the 

airplane by updating the EEC, which 

includes performing tests after removal 

and installation of the EEC. 

We reviewed Pratt & Whitney Canada 

Service Bulletin PW300–72–47202, 

Revision 3, also referred to as 47202R3, 

dated March 10, 2016. This service 

information describes procedures for 

modifying an engine by adjusting the 

engine N1 trim value for PW307A 

engines. 

We reviewed Pratt & Whitney Canada 

Service Bulletin PW300–72–47216, also 

referred to as 47216, dated January 13, 

2016. This service information describes 

procedures for modifying each engine 

installed on the airplane by updating 

the EEC, which includes installing 

software EEC version 307A0514. 

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 62 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with 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. 

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 to the Director of the System 

Oversight Division. 

Regulatory Findings 

We determined that 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); 


pmangrum on DSK3GDR082PROD with RULES
40476 Federal Register / Vol. 82, No. 164 / Friday, August 25, 2017 / Rules and Regulations 

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 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all The Boeing Company Model 

737–300, –400, and –500 series 

airplanes. The NPRM published in the 

Federal Register on March 9, 2017 (82 

FR 13079). The NPRM was prompted by 

a report that the fuel tank access door 

at wing buttock line 191.00 did not have 

an engineered ground path with the 

mating wing structure. The NPRM 

proposed to require replacing the fuel 

tank access door, doing a check of the 

electrical bond, doing related 

investigative and corrective actions if 

necessary, and revising the maintenance 

or inspection program by incorporating 

an AWL. We are issuing this AD to 

prevent an ungrounded path that could 

result in an increased risk of ignition 

and subsequent fuel tank explosion in 

the event of a lightning strike. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Support for the NPRM 

The Air Line Pilots Association, 

International, stated that it supports the 

NPRM. 

Request To Revise the Proposed AD To 

State the Compliance Time and Remove 

an Exception 

Boeing requested that we revise 

paragraph (g) of the proposed AD to 

state the specific compliance time 

‘‘within 36 months after the effective 

date of this AD,’’ rather than referring to 

the service information for compliance 

times. Boeing suggested that providing 

the compliance time in the body of the 

proposed AD would minimize 

confusion and misunderstanding. 

Boeing also requested that we remove 

paragraph (i)(1) of the proposed AD, 

which specifies an exception to the 

compliance time stated in the service 

information. Boeing further noted that 

we would also need to renumber 

paragraph (i)(2) of the proposed AD and 

update references to the affected 

paragraphs of the proposed AD. Boeing 

pointed out that if we stated the specific 

compliance time as requested, the 

exception language in paragraph (i)(1) of 

the proposed AD is no longer necessary. 

We agree with the requested changes 

for the reasons provided by the 

commenter. We have revised this AD 

accordingly. 

Request To Correct the Certification 

Maintenance Requirements (CMR) 

Document Title 

Boeing requested that we correct the 

title of the CMR document from ‘‘Boeing 

737–12345 . . .’’ to ‘‘Boeing 737–100/ 

200/200C/300/400/500 . . . .’’ 

We agree with this request and have 

corrected the document title in this final 

rule.
