Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 787–8 and 

787–9 airplanes. This proposed AD was 

prompted by a determination that 

certain areas in the tire/wheel threat 

zones could be susceptible to damage, 

which could result in loss of braking on 

one main landing gear (MLG) truck, loss 

of nose wheel steering, and loss of 

directional control on the ground when 

below rudder effectiveness speed. This 

proposed AD would require installing 

hydraulic tubing, a pressure-operated 

check valve, and new flight control 

software. We are proposing this AD to 

address the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by October 15, 2018. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

Boeing determined that certain areas 

in the tire/wheel threat zones could be 

susceptible to damage due to a thrown 

tire tread or tire burst. This could result 

in a loss of braking on one MLG truck, 

loss of nose wheel steering, and loss of 

directional control on the ground when 

below rudder effectiveness speed. The 

Model 787 hydraulic system is 

configured with a reserve steering 

system intended to maintain the nose 

wheel steering function in the event that 

a thrown tire tread or tire burst leads to 

a brake system failure such that 

differential braking cannot be used for 

directional control. Boeing has 

determined that damage from a MLG 

thrown tire tread or tire burst event 

could also result in the loss of the 

reserve steering system, resulting in loss 

of directional control on the ground and 

consequent runway excursion. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Alert Service 

Bulletins B787–81205–SB290032–00 

and B787–81205–SB290033–00, both 

Issue 001, both dated November 17, 

2017. This service information describes 

procedures for installing hydraulic 

tubing and installing a pressureoperated check valve. These documents 

are distinct since they apply to different 

airplane models. 

We also reviewed Boeing Alert 

Service Bulletin B787–81205– 

SB270039–00, Issue 002, dated March 8, 

2018. This service information describes 

procedures for installing new flight 

control software. 

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 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design.

Federal Register / Vol. 83, No. 170 / Friday, August 31, 2018 / Proposed Rules 44509 

Proposed AD Requirements 

This proposed AD would require 

accomplishment of the actions 

identified as ‘‘RC’’ (required for 

compliance) in the Accomplishment 

Instructions of the service information 

described previously, except for any 

differences identified as exceptions in 

the regulatory text of this proposed AD. 

For information on the procedures 

and compliance times, see this service 

information at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2018– 

0763. 

Difference Between This Proposed AD 

and the Service Information 

This proposed AD would require the 

software installation specified in Boeing 

Alert Service Bulletin B787–81205– 

SB270039–00, Issue 002, dated March 8, 

2018, prior to or concurrently with the 

tubing and valve installation on Model 

787–9 airplanes. The effectivity in this 

service information applies to Model 

787–8 and 787–9 airplanes; however, 

this proposed AD would only require 

those actions be accomplished on Model 

787–9 airplanes. 

Possible Additional Rulemaking for 

Software Installation 

We are considering additional 

rulemaking for Model 787–8 and 787–9 

airplanes to require the software 

installation specified in Boeing Alert 

Service Bulletin B787–81205– 

SB270039–00, Issue 002, dated March 8, 

2018, within a compliance time that 

may occur earlier than that for the 

tubing and valve installation specified 

in this proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 87 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed 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 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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Airbus SAS Model A330–200, –200F, 

and –300 series airplanes. This 

proposed AD was prompted by a 

revision of the airworthiness limitations 

section (ALS), which provides new and 

more restrictive maintenance 

requirements and airworthiness 

limitations for airplane structures and

require revising the maintenance or 

inspection program to incorporate new 

maintenance requirements and 

airworthiness limitations. We are 

proposing this AD to address the unsafe 

condition on these products. 

DATES: We must receive comments on 

this proposed AD by October 15, 2018.
