This proposed AD was prompted by a
report of heat damage found on a
nacelle firewall after an unsuccessful
engine ground start and several events
of heat damage found on direct current
starter/generator terminal block
assemblies. This proposed AD would
require an inspection for damage on the
nacelle firewalls and the terminal block
assemblies and to make sure the
insulating sleeves are installed and have
no damage, and corrective action if
necessary. We are proposing this AD to
prevent arcing between the firewall and
terminal blocks that are missing
insulating sleeves on the conductive
bushings, which could, in combination
with a fuel or hydraulic fluid leak, be
an ignition source for a fire.
DATES: We must receive comments on
this proposed AD by May 27, 2016.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Discussion
jstallworth on DSK7TPTVN1PROD with PROPOSALS
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2014–03R1,
dated July 24, 2014 (referred to after this
as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Bombardier, Inc. Model
DHC–8–102, –103, and –106 airplanes,
and Model DHC–8–200 and –300 series
airplanes. The MCAI states:
There has been one in-service report of
heat damage on a nacelle firewall found after
an unsuccessful engine ground start. There
have also been several reports of heat damage
found on Direct Current Starter/Generator
terminal block assemblies, part number (P/N)
82450075–001.
The investigation determined that in all
cases, the heat damage was caused by arcing
between the firewall and terminal blocks
with missing insulating sleeves on the
conductive bushings. The insulating sleeves
may have been inadvertently omitted during
the incorporation of Modsum 8/1926, or
during the installation of terminal blocks P/
N 82450075–001.
Arcing with the firewall becomes an
ignition source, creating a potential fire
hazard when combined with a fuel or
hydraulic fluid leak.
The original issue of this [Canadian] AD
mandated the [detailed visual] inspection [for

damage to the nacelle firewalls and to make
sure the insulating sleeves are installed and
have no damage] and rectification [corrective
actions such as installing or replacing
insulating sleeves, or replacing a terminal
block], as required, of the nacelle firewall
and terminal block assembly P/N 82450075–
001 installed with Modsum 8/1926.
Revision 1 of this [Canadian] AD is issued
to revise the Applicability to ensure that the
terminal blocks have the insulating sleeves
installed.
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–2016–
5044.
Relevant Service Information Under 1
CFR Part 51
Bombardier has issued Service
Bulletin 8–24–92, Revision A, dated
April 11, 2014. This service information
describes procedures for an inspection
for damage on the nacelle firewalls and
the terminal block assemblies and to
make sure the insulating sleeves are
installed and have no damage, and
corrective action if necessary. 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.
Costs of Compliance
We estimate that this proposed AD
affects 75 airplanes of U.S. registry.
We also estimate that it would take
about 2 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour. Based on
these figures, we estimate the cost of
this proposed AD on U.S. operators to
be $12,750, or $170 per product.
In addition, we estimate that any
necessary follow-on actions would take
about 1 work-hour and require parts
costing $551, for a cost of $636 per
product. We have no way of
determining the number of aircraft that
might need these 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.
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.

AGENCY:
We propose to adopt a new
airworthiness directive (AD) for all The
Boeing Company Model 737–600, –700,
–700C, –800, and –900 series airplanes.
This proposed AD was prompted by
reports of paint deterioration on the
surface of the main landing gear (MLG)
and the early onset of corrosion in the
trunnion bore of the MLG outer
cylinder. This proposed AD would
require identifying affected parts,
repetitive external surface detailed
inspection for damage of affected parts,
and related investigative and corrective
actions if necessary. For certain
airplanes, this AD also would require a
detailed inspection and bushing
replacement of the trunnion bore, and
related investigative and corrective
action if necessary. We are proposing
this AD to prevent stress corrosion
cracking of the external surfaces of the
MLG, which could result in a fracture of
the MLG and consequent MLG collapse.
DATES: We must receive comments on
this proposed AD by May 27, 2016.
ADDRESSES: You may send comments,

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-03R1, dated July 24, 2014 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for certain Bombardier, Inc. Model DHC-8-102, -103,
and -106 airplanes, and Model DHC-8-200 and -300 series airplanes. The
MCAI states:
There has been one in-service report of heat damage on a nacelle
firewall found after an unsuccessful engine ground start. There have
also been several reports of heat damage found on Direct Current
Starter/Generator terminal block assemblies, part number (P/N)
82450075-001.
The investigation determined that in all cases, the heat damage
was caused by arcing between the firewall and terminal blocks with
missing insulating sleeves on the conductive bushings. The
insulating sleeves may have been inadvertently omitted during the
incorporation of Modsum 8/1926, or during the installation of
terminal blocks P/N 82450075-001.
Arcing with the firewall becomes an ignition source, creating a
potential fire hazard when combined with a fuel or hydraulic fluid
leak.
The original issue of this [Canadian] AD mandated the [detailed
visual] inspection [for damage to the nacelle firewalls and to make
sure the insulating sleeves are installed and have no damage] and
rectification [corrective actions such as installing or replacing
insulating sleeves, or replacing a terminal block], as required, of
the nacelle firewall and terminal block assembly P/N 82450075-001
installed with Modsum 8/1926.
Revision 1 of this [Canadian] AD is issued to revise the
Applicability to ensure that the terminal blocks have the insulating
sleeves installed.
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-2016-
5044.
Relevant Service Information Under 1 CFR Part 51
Bombardier has issued Service Bulletin 8-24-92, Revision A, dated
April 11, 2014. This service information describes procedures for an
inspection for damage on the nacelle firewalls and the terminal block
assemblies and to make sure the insulating sleeves are installed and
have no damage, and corrective action if necessary. 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.
Costs of Compliance
We estimate that this proposed AD affects 75 airplanes of U.S.
registry.
We also estimate that it would take about 2 work-hours per product
to comply with the basic requirements of this proposed AD. The average
labor rate is $85 per work-hour. Based on these figures, we estimate
the cost of this proposed AD on U.S. operators to be $12,750, or $170
per product.
In addition, we estimate that any necessary follow-on actions would
take about 1 work-hour and require parts costing $551, for a cost of
$636 per product. We have no way of determining the number of aircraft
that might need these 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.
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.
