4828 Federal Register / Vol. 87, No. 20 / Monday, January 31, 2022 / Proposed Rules 

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. 

The FAA is 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. 

Regulatory Findings 

The FAA 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) Would not affect intrastate 

aviation in Alaska, and 

(3) Would 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

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain The Boeing Company Model 

767–200, –300, –300F, and –400ER 

airplanes. This proposed AD was 

prompted by reports of burned Boeing 

Material Specification (BMS) 8–39 

urethane foam, which is a material with 

fire-retardant properties that deteriorate 

with age. This proposed AD would

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Julie Linn, Aerospace 

Engineer, Cabin Safety and 

Environmental Systems Section, FAA, 

Seattle ACO Branch, 2200 South 216th 

St., Des Moines, WA 98198; phone and 

fax: 206–231–3584; email: Julie.Linn@

faa.gov. Any commentary that the FAA 

receives which is not specifically 

designated as CBI will be placed in the 

public docket for this rulemaking. 

Background 

The FAA has received reports of 

burned BMS 8–39 urethane foam, a 

material with fire-retardant properties. 

The fire-retardant properties of BMS 8– 

39 urethane foam deteriorate with age. 

The degraded material can be an 

unacceptable fire fuel source for a fire 

if exposed to an ignition source. The 

degraded material in the seals will 

compromise Halon and smoke retention 

and fire blocking, which could result in 

the inability to keep sufficient Halon 

concentrations within the cargo 

compartment or contain fire or smoke. 

These conditions, if not addressed, 

could result in penetration of smoke or 

fire into the flight compartment, leading 

to possible loss of control of the 

airplane. 

Related AD 

The FAA issued AD 2013–11–04, 

Amendment 39–17464 (78 FR 33193, 

June 4, 2013) (AD 2013–11–04), for 

certain The Boeing Company Model 

747–100, 747–100B, 747–100B SUD, 

747–200B, 747–200F, 747–300, 747– 

400, 747–400D, 747–400F, 747SR, and 

747SP series airplanes; Model 767–200, 

–300, –300F, and –400ER series 

airplanes; and Model 777–200, –200LR, 

–300, and –300ER series airplanes. For 

Model 767–200, –300, –300F, and 

–400ER series airplanes, AD 2013–11– 

04 requires replacing certain seals made 

of BMS 8–39 urethane foam in 

accordance with Boeing Special 

Attention Service Bulletin 767–25– 

0381, Revision 1, dated September 17, 

2012, which the Director of the Federal 

Register approved for incorporation by 

reference as of July 9, 2013 (78 FR 

33193, June 4, 2013). AD 2013–11–04 

resulted from operator or in-service 

reports of burned BMS 8–39 urethane 

foam, and a report from the airplane 

manufacturer indicating that airplanes 

were assembled, throughout various 

areas of the airplane (including flight 

deck and cargo compartments), with 

seals made of BMS 8–39 urethane foam. 

The FAA issued AD 2013–11–04 to 

address the failure of urethane seals to 

maintain sufficient halon concentrations 

in the cargo compartments to extinguish 

or contain fire or smoke, and to prevent 

penetration of fire or smoke in areas of 

the airplane that are difficult to access 

for fire and smoke detection or 

suppression. 

This NPRM proposes to require 

additional actions for certain Model 

767–200, –300, –300F, and –400ER 

series airplanes, in accordance with 

Boeing Special Attention Service 

Bulletin 767–25–0381, Revision 4, dated 

April 26, 2021. This NPRM does not 

propose to supersede AD 2013–11–04. 

Rather, the FAA has determined that a 

stand-alone AD would be more 

appropriate because the additional work 

applies only to Model 767–200, –300, 


khammond on DSKJM1Z7X2PROD with PROPOSALS
4830 Federal Register / Vol. 87, No. 20 / Monday, January 31, 2022 / Proposed Rules 

–300F, and –400ER series airplanes 

having certain configurations. 

Actions Since AD 2013–11–04 Was 

Issued 

Since AD 2013–11–04 was issued, the 

FAA has determined that replacement 

or removal of certain BMS 8–39 

urethane foam pads and an inspection 

of certain corner seals is necessary for 

certain Model 767–200, –300, –300F, 

and –400ER airplanes that are in AD 

2013–11–04. This proposed AD would 

only require the actions for Model 767– 

200, –300, –300F, and –400ER series 

airplanes, identified as Group 1, 

Configuration 4; Group 2, 3, 12, and 13, 

Configuration 3; Group 14, 

Configuration 1 and 3; Group 15, 

Configuration 2; and Group 17, 

Configuration 3 and 4, in Boeing Special 

Attention Service Bulletin 767–25– 

0381, Revision 4, dated April 26, 2021. 

This proposed AD addresses the unsafe 

condition only for these airplanes as 

identified in paragraph (c) of this 

proposed AD. Therefore, this proposed 

AD would not supersede AD 2013–11– 

04. 

FAA’s Determination 

The FAA is issuing this NPRM after 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing Special 

Attention Service Bulletin 767–25– 

0381, Revision 4, dated April 26, 2021. 

This service information specifies, 

among other actions, procedures for 

replacing certain BMS 8–39 foam pads 

with Nomex felt in the forward and aft 

crown area, removing certain BMS 8–39 

foam pads in the crown area (which 

includes a general visual inspection to 

find BMS 8–39 foam pads) for certain 

airplanes, inspecting the corner seals to 

determine if the corner seals were 

replaced, and replacing affected corner 

seals. The required actions depend on 

requirements for use and location of the 

BMS 8–39 urethane foam in the 

airplane. 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 

ADDRESSES. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

the service information already. This 

proposed AD would also prohibit the 

installation of affected parts. For 

information on the procedures, see this 

service information at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

1177. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 396 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection (1 airplane) .................................... 33 work-hours × $85 per hour = $2,805 ........ $0 ................... $2,805 $2,805 

Replacement of foam pad with Nomex felt 

(361 airplanes).

29 work-hours × $85 per hour = $2,465 ........ Negligible * ..... 2,465 889,865 

Removal (34 airplanes) .................................. 29 work-hours × $85 per hour = $2,465 ........ $0 ................... 2,465 83,810 

* Parts are Nomex felt, adhesive, and tapes. There are no kits for this required action. 

The FAA estimates the following 

costs to do any necessary replacements 

that would be required based on the 

results of the proposed inspection. The 

agency has no way of determining the 

number of aircraft that might need this 

replacement: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement of corner seals ....................................... 1 work-hour × $85 per hour = $85 .............................. Up to $3,848 .. Up to $3,933. 

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. 

The FAA is 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. 

Regulatory Findings 

The FAA 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) Would not affect intrastate 

aviation in Alaska, and 

(3) Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.
