Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2017–30,
dated August 30, 2017 (referred to after
this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
VerDate Sep<11>2014
17:10 Jul 05, 2018
Jkt 244001
MCAI’’), to correct an unsafe condition
for certain Bombardier, Inc., Model
DHC–8–300 series airplanes. The MCAI
states:
An operator has reported the inability to
open the Forward Right Hand Type I
emergency exit door with either the internal
or external handle during maintenance.
Investigation has determined that the handle
was found to be jammed due to corroded
center and lower shaft ball bearings.
Condensation has been found to be the root
cause of the Forward Right Hand Type I
emergency exit door hardware corrosion.
Other Forward Right Hand Type I emergency
exit door ball bearings are also susceptible to
corrosion. Inability to open the Forward
Right Hand Type I emergency exit door
during an emergency evacuation may impede
aircraft egress.
This [Canadian] AD mandates the
inspection for corrosion and replacement, as
required, of all Forward Right Hand Type I
emergency exit door ball bearings, and the
application of corrosion inhibiting
compound (CIC), to ensure that the Forward
Right Hand Type I emergency exit door can
be opened when required.
Required actions also include an
inspection of the emergency exit door
ball bearings for seal damage and loss of
lubricant and revision of the
maintenance or inspection program, as
applicable. You may examine the MCAI
in the AD docket on the internet at
https://www.regulations.gov by searching
for and locating Docket No. FAA–2018–
0586.
Related Service Information Under 1
CFR Part 51
Bombardier has issued the following
service information:
• Service Bulletin 8–52–65, dated
July 26, 2017, which describes
procedures for a detailed inspection of
the forward right-hand type 1
emergency exit door ball bearings for
corrosion, seal damage, and loss of
lubricant; applying CIC; and replacing
emergency exit door ball bearings if
necessary.
• Maintenance Review Board (MRB)
Task 5220/12 (‘‘Servicing of Forward
RH Emergency Exit Mechanisms’’),
dated March 15, 2017, of the DHC–8–
300 Series Maintenance Program
Support Manual (PSM) 1–83–7, which
describes procedures for servicing the
forward right-hand emergency exit door
mechanisms.

FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
This AD requires revisions to certain
operator maintenance documents to
include new actions (e.g., inspections).
Compliance with these actions is
required by 14 CFR 91.403(c). For
airplanes that have been previously
modified, altered, or repaired in the
areas addressed by this proposed AD,
the operator may not be able to
accomplish the actions described in the
revisions. In this situation, to comply
with 14 CFR 91.403(c), the operator
must request approval for an alternative
method of compliance according to
paragraph (j)(1) of this proposed AD.
The request should include a
description of changes to the required
actions that will ensure the continued
damage tolerance of the affected
structure.
Differences Between This Proposed AD
and the MCAI
The MCAI requires the incorporation
of MRB Task 5220/12 (‘‘Servicing of
Forward RH Emergency Exit
Mechanisms’’) into the maintenance
program. That task refers to the AMM
for certain procedures, which have been
updated. We understand that the MCAI
does not require the updated AMM
procedures because, unlike U.S.
operators, Canadian operators are
already required to use the most current
AMM procedures. Therefore, this
proposed AD would also require the
incorporation of Bombardier TR 54–042,
dated April 10, 2018, which includes
the updated AMM procedures.
Costs of Compliance
We estimate that this proposed AD
affects 16 airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:

$255
$4,080
We have determined that revising the
maintenance or inspection program
takes an average of 90 work-hours per
operator, although we recognize that
this number may vary from operator to
operator. In the past, we have estimated
that this action takes 1 work-hour per
airplane. Since operators incorporate
maintenance or inspection program
changes for their affected fleet(s), we
have determined that a per-operator
estimate is more accurate than a perairplane estimate. Therefore, we
estimate the total cost per operator to be
$7,650 (90 work-hours × $85 per workhour).
We estimate the following costs to do
any necessary on-condition actions that
would be required based on the results
of any required actions. We have no way
of determining the number of aircraft
that might need these on-condition
actions:

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
VerDate Sep<11>2014
17:10 Jul 05, 2018
Jkt 244001
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.

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2017-30, dated August 30, 2017 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for certain Bombardier, Inc., Model DHC-8-300 series
airplanes. The MCAI states:
An operator has reported the inability to open the Forward Right
Hand Type I emergency exit door with either the internal or external
handle during maintenance. Investigation has determined that the
handle was found to be jammed due to corroded center and lower shaft
ball bearings. Condensation has been found to be the root cause of
the Forward Right Hand Type I emergency exit door hardware
corrosion. Other Forward Right Hand Type I emergency exit door ball
bearings are also susceptible to corrosion. Inability to open the
Forward Right Hand Type I emergency exit door during an emergency
evacuation may impede aircraft egress.
This [Canadian] AD mandates the inspection for corrosion and
replacement, as required, of all Forward Right Hand Type I emergency
exit door ball bearings, and the application of corrosion inhibiting
compound (CIC), to ensure that the Forward Right Hand Type I
emergency exit door can be opened when required.
Required actions also include an inspection of the emergency exit
door ball bearings for seal damage and loss of lubricant and revision
of the maintenance or inspection program, as applicable. You may
examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0586.
Related Service Information Under 1 CFR Part 51
Bombardier has issued the following service information:
Service Bulletin 8-52-65, dated July 26, 2017, which
describes procedures for a detailed inspection of the forward right-
hand type 1 emergency exit door ball bearings for corrosion, seal
damage, and loss of lubricant; applying CIC; and replacing emergency
exit door ball bearings if necessary.
Maintenance Review Board (MRB) Task 5220/12 (``Servicing
of Forward RH Emergency Exit Mechanisms''), dated March 15, 2017, of
the DHC-8-300 Series Maintenance Program Support Manual (PSM) 1-83-7,
which describes procedures for servicing the forward right-hand
emergency exit door mechanisms.
Temporary Revision (TR) 54-042, dated April 10, 2018, to
the DHC-8-300 Aircraft Maintenance Manual (AMM), which describes
procedures for servicing the type 1 emergency exit door mechanisms.
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 and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
This AD requires revisions to certain operator maintenance
documents to include new actions (e.g., inspections). Compliance with
these actions is required by 14 CFR 91.403(c). For airplanes that have
been previously modified, altered, or repaired in the areas addressed
by this proposed AD, the operator may not be able to accomplish the
actions described in the revisions. In this situation, to comply with
14 CFR 91.403(c), the operator must request approval for an alternative
method of compliance according to paragraph (j)(1) of this proposed AD.
The request should include a description of changes to the required
actions that will ensure the continued damage tolerance of the affected
structure.
Differences Between This Proposed AD and the MCAI
The MCAI requires the incorporation of MRB Task 5220/12
(``Servicing of Forward RH Emergency Exit Mechanisms'') into the
maintenance program. That task refers to the AMM for certain
procedures, which have been updated. We understand that the MCAI does
not require the updated AMM procedures because, unlike U.S. operators,
Canadian operators are already required to use the most current AMM
procedures. Therefore, this proposed AD would also require the
incorporation of Bombardier TR 54-042, dated April 10, 2018, which
includes the updated AMM procedures.
Costs of Compliance
We estimate that this proposed AD affects 16 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
[[Page 31498]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255........................... $0 $255 $4,080
----------------------------------------------------------------------------------------------------------------
We have determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although we
recognize that this number may vary from operator to operator. In the
past, we have estimated that this action takes 1 work-hour per
airplane. Since operators incorporate maintenance or inspection program
changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate.
Therefore, we estimate the total cost per operator to be $7,650 (90
work-hours x $85 per work-hour).
We estimate the following costs to do any necessary on-condition
actions that would be required based on the results of any required
actions. We have no way of determining the number of aircraft that
might need these on-condition actions:
Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
6 work-hours x $85 per hour = $510............................................ $586 $1,096
----------------------------------------------------------------------------------------------------------------
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.

unless already done.
(g) Revision of Maintenance or Inspection Program
Within 60 days after the effective date of this AD: Revise the
maintenance or inspection program, as applicable, to incorporate
Maintenance Review Board Task 5220/12 (``Servicing of Forward RH
Emergency Exit Mechanisms''), dated March 15, 2017, of the DHC-8-300
Series Maintenance Program Support Manual (PSM) 1-83-7; and
Temporary Revision 54-042, dated April 10, 2018, to the DHC-8-300
Aircraft Maintenance Manual (AMM). The initial compliance time for
doing the task is
[[Page 31499]]
at the time specified in Maintenance Review Board Task 5220/12
(``Servicing of Forward RH Emergency Exit Mechanisms'') of the DHC-
8-300 Series Maintenance PSM 1-83-7, or within 60 days after the
effective date of this AD, whichever occurs later.
(h) Inspection and Replacement
Within 5,000 flight hours or 36 months, whichever occurs first,
after the effective date of this AD: Do a detailed inspection of all
ball bearings of the forward right-hand type I emergency exit for
corrosion, seal damage, and loss of lubricant; replace bearings as
applicable; and apply corrosion inhibiting compound (CIC); in
accordance with the Accomplishment Instructions of Bombardier
Service Bulletin 8-52-65, dated July 26, 2017. Do all applicable
replacements before further flight.
(i) No Alternative Actions or Intervals
After the maintenance or inspection program has been revised as
required by paragraph (g) of this AD, no alternative actions (e.g.,
inspections) or intervals may be used unless the actions and
intervals are approved as an alternative method of compliance (AMOC)
in accordance with the procedures specified in paragraph (j)(1) of
this AD.
(j) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
