14 CFR Part 39

[Docket No. FAA-2018-0635; Product Identifier 2017-NM-183-AD; Amendment 
39-19490; AD 2018-23-04]
RIN 2120-AA64


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

                                         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:

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.
