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-8-102, -103, and -106 airplanes; Model DHC-
8-200 series airplanes; and Model DHC-8-300 series airplanes. This AD
was prompted by a report that a certain modification to the auto
relight system is incompatible with a certain beta lockout system
modification and could result in de-activation of the auto ignition
feature of the No. 2 engine. This AD requires an inspection of the auto
ignition system and applicable rectification. We are issuing this AD to
address the unsafe condition on these products.
DATES: This AD is effective March 15, 2019.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of March 15,
2019.

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-8-102, -103, and -106 airplanes; Model DHC-8-200 series
airplanes; and Model DHC-8-300 series airplanes. The NPRM published in
the Federal Register on July 23, 2018 (83 FR 34800). The NPRM was
prompted by a report that a certain modification to the auto relight
system is incompatible with a certain beta lockout system modification
and could result in de-activation of the auto ignition feature of the
No. 2 engine. The NPRM proposed to require an inspection of the auto
ignition system and applicable rectification. We are issuing this AD to
address unintentional de-activation of the auto ignition feature of the
No. 2 engine when the beta lockout system is activated, which could
result in an uncommanded in-flight shutdown of the No. 2 engine.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2017-21R1, dated June
28, 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-8-102, -103, and -106
airplanes; Model DHC-8-200 series airplanes; and Model DHC-8-300 series
airplanes. The MCAI states:
During the incorporation of the Auto Relight modification per
Bombardier SB [Service Bulletin] 8-74-02 on an aeroplane with a Beta
Lockout System (BLS) installed, it was noticed that if SB 8-74-02 is
incorporated in conjunction with, or after the incorporation of BLS
SB 8-76-35 ([Canadian] AD CF-2013-15) or SB 8-76-24 (FAA AD 2000-02-
13 [Amendment 39-11531 (65 FR 4095, January 26, 2000)]), the #2
engine auto ignition function of the beta lockout system will not be
available when the beta lockout system is activated. This condition,
if not corrected, may result in a #2 engine uncommanded in-flight
shut down.
To preclude any future occurrence of the noted deficiency,
Bombardier has issued SB 8-74-02 Revision B to highlight its
incompatibility with post SB 8-76-35 or 8-76-24 BLS compliant
aeroplanes. In addition, Bombardier issued a new SB, 8-74-06 for
Auto Relight System modification that can be incorporated in
conjunction with or on those aeroplanes that were previously
modified per SB 8-76-35 or 8-76-24.
To address this potentially unsafe condition, Bombardier has
also issued SB 8-74-07 to inspect and rectify the system wiring on
affected aeroplanes.
The original version of this [Canadian] AD was issued to mandate
compliance with the SB 8-74-07 requirements.
Revision 1 of this [Canadian] AD is issued to clarify the
Applicability section and correct a typographic error in the SB
number referenced in the Corrective Action section of the original
[Canadian] AD.
You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0635.
Comments
We gave the public the opportunity to participate in developing
this final rule. We have considered the comment received. The Air Line
Pilots Association, International (ALPA) indicated its support for the
NPRM.
Conclusion
We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting
this final rule as proposed, except for minor
[[Page 2708]]
editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
Bombardier has issued Service Bulletin 8-74-07, dated April 13,
2016. This service information describes procedures for an inspection
to determine correct operation of the auto ignition system for
airplanes on which a beta lockout system was installed, and
rectification to re-activate a previously disabled auto ignition system
that will address inadvertent de-activation of the auto ignition
feature. 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.
Costs of Compliance
We estimate that this AD affects 185 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection............................ 1 work-hour x $85 per $0 $85 $15,725
hour = $85.
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary on-condition
actions that would be required based on the results of the inspection.
We have no way of determining the number of aircraft that might need
this action:
On-Condition Costs

Rectification................................. 3 work-hours x $85 per hour = $6 $261

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 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 and
associated appliances to the Director of the System Oversight Division.
Regulatory Findings
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.
