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 The Boeing Company 

Model 747–100, –100B, –100B SUD, 

–200B, –200C, –200F, –300, –400, 

–400D, 747SP, and 747SR, and 747–8 

series airplanes. The NPRM published 

in the Federal Register on April 17, 

2018 (83 FR 16796). The NPRM was 

prompted by reports indicating that 

additional areas of BMS 8–39 flexible 

urethane foam were found during an 

inspection required by a related AD. 

The NPRM proposed to require 

inspecting for BMS 8–39 flexible 

urethane foam insulation in the floor 

panel assemblies and the PDU cover 

assemblies, doing applicable oncondition actions, modifying certain 

dripshields, and replacing BMS 8–39 

foam strips on certain dripshields with 

BMS 8–371 foam strips. 

We are issuing this AD to address 

BMS 8–39 flexible urethane foam in 

certain areas, which, if exposed to an 

ignition source, could cause an 

uncontrolled fire leading to loss of 

control of the airplane. 

Comments 

We gave the public the opportunity to 

participate in developing this final rule. 

We have considered the comment 

received. Boeing stated that it had no 

objection to the NPRM. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, 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 

We reviewed the following Boeing 

service information. 

• Boeing Special Attention Service 

Bulletin 747–53–2877, dated August 5, 

2014, which describes procedures for 

performing a general visual inspection 

for BMS 8–39 flexible urethane foam 

insulation in the floor panel assemblies 

and the PDU cover assemblies, and 

applicable on-condition actions. 

• Boeing Special Attention Service 

Bulletin 747–25–3646, Revision 1, dated 


amozie on DSK3GDR082PROD with RULES
38958 Federal Register / Vol. 83, No. 153 / Wednesday, August 8, 2018 / Rules and Regulations 

August 2, 2017, which describes 

procedures for replacing BMS 8–39 

foam strips with BMS 8–371 foam strips 

on certain dripshields. 

• Boeing Special Attention Service 

Bulletin 747–25–3692, dated June 22, 

2016, which describes procedures for 

modifying and replacing BMS 8–39 

foam strips with BMS 8–371 foam strips 

on certain dripshields. 

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 87 

airplanes of U.S. registry. We estimate 

the following costs to comply with this 

AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection and replacement ....... 25 work-hour × $85 per hour = 

$2,125.

Up to $184,460 ..... Up to $186,585 ..... Up to $6,157,305 (33 airplanes 

affected). 

Modification and installation of 

the dripshields.

10 work-hours × $85 per hour = 

$850.

Unavailable 1 ......... $850 ...................... $44,200 (52 airplanes affected). 

Replacement of the foam on the 

dripshields.

8 work-hours × $85 per hour = 

$680.

Unavailable 1 ......... $680 ...................... $4,760 (7 airplanes affected). 

1We have received no definitive data that would enable us to provide parts cost estimates as the parts and materials are to be supplied by the 

operator for the actions specified in this AD. 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition actions 

specified in this AD. 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. As a result, we 

have included all available costs in our 

cost estimate. 

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 

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.
