Airworthiness Directives; The Boeing
Company Airplanes
AGENCY
: Federal Aviation
Administration (FAA), DOT.
ACTION
: Notice of proposed rulemaking
(NPRM).
SUMMARY
: The FAA proposes to adopt a
new airworthiness directive (AD) for all
The Boeing Company Model 737–8 and
737–9 airplanes. This proposed AD was
prompted by a report that, after the
removal of a spring door opening system
(SDOS) actuator with a certain part
number, the actuator came apart,
injuring one of the maintenance
personnel. A design that obscures the
SDOS actuator safety marker when the
fan cowls are opened contributed to this
incident. This proposed AD would
require replacing each affected SDOS
actuator with a new SDOS actuator and
verifying that new safety markers are
installed in the proper locations. The
FAA is proposing this AD to address the
unsafe condition on these products.
DATES
: The FAA must receive comments
on this proposed AD by June 4, 2020.

Discussion
The SDOS actuator is a telescopic,
spring-loaded actuator that assists the
mechanic in raising the engine fan cowl.
Even when the actuator is extended
(uncompressed), it retains energy in the
spring (preload).
The FAA received a report indicating
that, after the removal of an SDOS
actuator with part number BOE–2001–
901F, a part separation occurred at the
joint between the actuator’s inner tube
and its related ‘‘back end’’ bracket, and
the actuator came apart with spring-
propelled force, injuring one of the
maintenance personnel. The SDOS
actuator uses two roll pins and epoxy at

Federal Register / Vol. 85, No. 76 / Monday, April 20, 2020 / Proposed Rules
this joint. The FAA has determined that
this design, together with spring
preload, caused these parts to break. In
addition, the current design of the
actuator obscures the safety marker
when the fan cowls are opened. The
design of the SDOS actuator, along with
obscured safety markers, if not
addressed, could, during maintenance,
result in injury to maintenance
personnel or damage to the airplane.
The manufacturer of the SDOS
actuator, General Aerospace, changed
the design to have a stronger inner tube
to ‘‘back end’’ bracket joint that uses
blind rivets rather than pins, together
with an improved shape of the
‘‘catching’’ bracket. With this design
change, the SDOS actuator became part
number BOE–2001–901H. General
Aerospace has since modified part
number BOE–2001–901H to include
more detailed safety markers in new
locations that display the warnings
more clearly to maintenance personnel.
As part of this modification, the SDOS
actuator part number was changed from
BOE–2001–901H to BOE–2001–901J.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Boeing Special
Attention Requirements Bulletin 737–
71–1911 RB, dated November 26, 2019.
This service information describes
procedures for replacing each affected
SDOS actuator with a new SDOS
actuator and verifying that safety
markers are installed. 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
The FAA is proposing this AD
because the agency 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.
Proposed AD Requirements
This proposed AD would require
accomplishment of the actions
identified in Boeing Special Attention
Requirements Bulletin 737–71–1911 RB,
dated November 26, 2019, described
previously, except as discussed under
‘‘Differences Between this Proposed AD
and the Service Information,’’ and
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
https://www.regulations.gov by
searching for and locating Docket No.
FAA–2020–0333.
Explanation of Requirements Bulletin
The FAA worked in conjunction with
industry, under the Airworthiness
Directive Implementation Aviation
Rulemaking Committee (AD ARC), to
enhance the AD system. One
enhancement is a process for annotating
which steps in the service information
are ‘‘required for compliance’’ (RC) with
an AD. Boeing has implemented this RC
concept into Boeing service bulletins.
In an effort to further improve the
quality of ADs and AD-related Boeing
service information, a joint process
improvement initiative was worked
between the FAA and Boeing. The
initiative resulted in the development of
a new process in which the service
information more clearly identifies the
actions needed to address the unsafe
condition in the ‘‘Accomplishment
Instructions.’’ The new process results
in a Boeing Requirements Bulletin,
which contains only the actions needed
to address the unsafe condition (i.e.,
only the RC actions).
Differences Between This Proposed AD
and the Service Information
The effectivity of Boeing Special
Attention Requirements Bulletin 737–
71–1911 RB, dated November 26, 2019,
is limited to certain Boeing Model 737–
8 and 737–9 airplanes. However, the
applicability of this proposed AD
includes all Boeing Model 737–8 and
737–9 airplanes. Because the affected
parts are rotable parts, the FAA has
determined that these parts could later
be installed on airplanes that were
initially delivered with acceptable parts,
thereby subjecting those airplanes to the
unsafe condition.
Costs of Compliance
The FAA estimates that This
proposed AD affects 160 airplanes of
U.S. registry. The FAA estimates the
following costs to comply with this
proposed AD:
E
STIMATED
C
OSTS FOR
R
EQUIRED

operators
Replace SDOS actuator ......... 5 work-hours × $85 per hour = $13,600 ................................ $ * $13,600* $2,176,000 *
* The FAA has received no definitive data that would enable the agency to provide parts cost estimates for the actions specified in this pro-
posed AD.
The FAA has included all known
costs in its cost estimate. According to
the manufacturer, however, some or all
of the costs of this proposed AD may be
covered under warranty, thereby
reducing the cost impact on affected
persons.
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 has 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) Will not affect intrastate aviation
in Alaska, and

Safety.
The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
PART 39—AIRWORTHINESS
DIRECTIVES
■1. The authority citation for part 39
continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13 [Amended]
■2. The FAA amends § 39.13 by adding
the following new airworthiness
directive (AD):
The Boeing Company: Docket No. FAA–
2020–0333; Product Identifier 2020–
NM–015–AD.
(a) Comments Due Date
The FAA must receive comments by June
4, 2020.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all The Boeing
Company Model 737–8 and 737–9 airplanes,
certificated in any category.
(d) Subject
Air Transport Association (ATA) of
America Code 71, Powerplant.
(e) Unsafe Condition
This AD was prompted by a report that,
after the removal of a spring door opening
system (SDOS) actuator with a certain part
number, a part separation occurred at a
certain location, which caused an injury to
one of the maintenance personnel. A design
that obscures the SDOS actuator safety
marker when the fan cowls are opened
contributed to this incident. The FAA is
issuing this AD to address possible
separation of the SDOS actuator at the joint
between the inner tube and the ‘‘back end’’
bracket, and visual obstruction of the SDOS
actuator safety marker, which, during
maintenance, can cause injury to
maintenance personnel or damage to the
airplane.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
(g) Required Actions
For airplanes identified in Boeing Special
Attention Requirements Bulletin 737–71–
1911 RB, dated November 26, 2019, except as
specified by paragraph (h) of this AD: At the
applicable times specified in the
‘‘Compliance’’ paragraph of Boeing Special
Attention Requirements Bulletin 737–71–
1911 RB, dated November 26, 2019, do all
applicable actions identified in, and in
accordance with, the Accomplishment
Instructions of Boeing Special Attention
Requirements Bulletin 737–71–1911 RB,
dated November 26, 2019.
Note 1 to paragraph (g): Guidance for
accomplishing the actions required by this
AD can be found in Boeing Special Attention
Service Bulletin 737–71–1911, dated
November 26, 2019, which is referred to in
Boeing Special Attention Requirements

26, 2019.
(h) Exception to Service Information
Specifications
Where Boeing Special Attention
Requirements Bulletin 737–71–1911 RB,
dated November 26, 2019, uses the phrase
‘‘the original issue date of Requirements
Bulletin 737–71–1911 RB,’’ this AD requires
using ‘‘the effective date of this AD.’’
(i) Parts Installation Prohibition
As of the effective date of this AD, no
person may install an SDOS actuator, having
part numbers BOE–2001–901F or BOE–2001–
901H, on any airplane.
