We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by a report of loose bolts that are intended to secure the translating door crank assembly to the outside handle shaft. This AD requires a detailed inspection for loose bolts on the aft translating door crank assembly, and removal and reinstallation of the bolts. We are issuing this AD to prevent loose bolts from falling out. If both bolts become loose or fall out after the door is closed and locked, the door cannot be opened from inside or outside, which could impede evacuation in the event of an emergency.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted
by a report of loose bolts that are intended to secure the translating
door crank assembly to the outside handle shaft. This AD requires a
detailed inspection for loose bolts on the aft translating door crank
assembly, and removal and reinstallation of the bolts. We are issuing
this AD to prevent loose bolts from falling out. If both bolts become
loose or fall out after the door is closed and locked, the door cannot
be opened from inside or outside, which could impede evacuation in the
event of an emergency.

DATES: This AD becomes effective August 11, 2015.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of August 11,
2015.

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 Bombardier, Inc.
Model DHC-8-400 series airplanes. The NPRM published in the Federal
Register on August 15, 2014 (79 FR 48105). The NPRM was prompted by a
report of loose bolts that are intended to secure the translating door
crank assembly to the outside handle shaft. The NPRM proposed to
require a detailed inspection for loose bolts on the aft translating
door crank assembly, and removal and reinstallation of the bolts. We
are issuing this AD to prevent loose bolts from falling out. If both
bolts become loose or fall out after the door is closed and locked, the
door cannot be opened from inside or outside, which could impede
evacuation in the event of an emergency.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-08, dated February 10, 2014 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for the specified products. The MCAI
states:

There was one in-service report where the bolts securing the
translating door crank assembly to the outside handle shaft were
found loose. It was also found on another translating door that
sealant was missing on these bolts. If both bolts become loose or
fall out after the door is closed and locked, the door cannot be
opened from inside or outside.
The aft entry translating door and aft service translating door
are classified as emergency exits. The inability to open an
emergency exit could impede evacuation in the event of an emergency.
This [Canadian] AD mandates the inspection of the translating
door crank assemblies for loose bolts, as well as appropriate
rectification [removal and reinstallation of the bolts].

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0569-0002.

Comments

We gave the public the opportunity to participate in developing
this AD. We have considered the comment received. The following
presents the comment received on the NPRM (79 FR 48105, August 15,
2014), and the FAA's response to the comment.

Request To Remove Certain Requirements From the NPRM (79 FR 48105,
August 15, 2014)

Horizon Air requested that the job set-up and close-out procedures
included in Part A-INSPECTION, and Part B-RECTIFICATION, of the
Accomplishment Instructions of Bombardier Service Bulletin 84-52-75,
Revision A, dated July 11, 2013, be removed as requirements in the NPRM
(79 FR 48105, August 15, 2014). The commenter noted that only the
procedures included in paragraph B.

[[Page 38616]]

Procedure, of Part A and Part B of the Accomplishment Instructions of
Bombardier Service Bulletin 84-52-75, Revision A, dated July 11, 2013,
provide corrective actions to address the unsafe condition. The
commenter stated that the job set-up and close-out procedures do not
directly correct the unsafe condition and restrict an operators'
ability to perform maintenance in conjunction with the detailed
inspection that would be required by the proposed AD.
We partially agree with the commenter's request. We agree to remove
the job set-up procedures and most of the steps in the job close-out
procedures from this AD because those actions do not directly correct
the unsafe condition. We have revised paragraph (g) of this AD to
specify that the inspection must be done in accordance with paragraph
3.B., ``Procedure,'' of Part A--INSPECTION, of the Accomplishment
Instructions of Bombardier Service Bulletin 84-52-75, Revision A, dated
July 11, 2013.
We have also revised paragraphs (g)(1) and (g)(2) of this AD to
specify that the corrective actions must be done in accordance with
paragraph 3.B., ``Procedure,'' and steps 3.C.(4) and 3.C.(5) of
paragraph 3.C., ``Close Out,'' of Part B--RECTIFICATION, of the
Accomplishment Instructions of Bombardier Service Bulletin 84-52-75,
Revision A, dated July 11, 2013. The intent of this final rule is to
ensure that the aft entry translating door and aft service translating
door are correctly installed. Therefore, we consider the operational
tests in steps 3.C.(4) and 3.C.(5) of paragraph 3.C., ``Close Out,'' of
Part B--RECTIFICATION, of the Accomplishment Instructions of Bombardier
Service Bulletin 84-52-75, Revision A, dated July 11, 2013, to be
required actions to ensure that these doors operate properly. If
maintenance is done concurrently with the required detailed inspection,
it should not affect an operator's ability to return the aircraft to
service. If the required detailed inspection cannot be completed
because the airplane is undergoing maintenance, then the actions
required by this AD can be accomplished just prior to the airplane
being returned to service. Concurrently performing maintenance and
doing the actions required by this AD should not cause a delay in an
airplane's return to service.

Conclusion

We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting
this AD 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 (79 FR 48105, August 15, 2014) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 48105, August 15, 2014).

Related Service Information Under 1 CFR Part 51

We reviewed Bombardier Service Bulletin 84-52-75, Revision A, dated
July 11, 2013. This service information describes procedures for a
detailed inspection for loose bolts on the aft translating door crank
assembly, and removal and reinstallation of the bolts. 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 of this AD.

Costs of Compliance

We estimate that this AD affects 82 airplanes of U.S. registry.
We also estimate that it will take about 7 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $0 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $48,790, or $595 per product.

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 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 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.
