Airworthiness Directives; Saab AB, Saab Aeronautics (Formerly 
Known as Saab AB, Saab Aerosystems) Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2018-11-07, 
which applied to all Saab AB, Saab Aeronautics Model SAAB 2000 
airplanes. AD 2018-11-07 required a one-time inspection of an affected 
lug attaching the aileron bellcrank support bracket to the rear spar of 
the wing and the adjacent area of the installed support brackets, a 
thickness measurement of the affected lug, repetitive inspections of 
the affected aileron bellcrank support brackets, and corrective actions 
if necessary. AD 2018-11-07 also provided an optional terminating 
action for the repetitive inspections. This AD retains the actions of 
AD 2018-11-07 and requires the terminating action for the repetitive 
inspections. This AD was prompted by a determination that it is 
necessary to require the terminating action. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective January 14, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 13, 
2018 (83 FR 24399, May 29, 2018).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2018-11-07, Amendment 39-19295 (83 FR 24399, 
May 29, 2018) (``AD 2018-11-07''). AD 2018-11-07 applied to all Saab 
AB, Saab Aeronautics Model SAAB 2000 airplanes. The NPRM published in 
the Federal Register on September 19, 2018 (83 FR 47321). The NPRM was 
prompted by a determination that further rulemaking is necessary to 
include the requirement to replace all affected support brackets. The 
NPRM proposed to continue to require one-time inspection of the 
affected lug attaching the aileron bellcrank support bracket to the 
rear spar of the wing and the adjacent area of the installed aileron 
bellcrank support brackets, a thickness measurement of the affected lug 
attaching the support bracket to the rear spar of the wing, repetitive 
inspections of the affected aileron bellcrank support brackets, and 
corrective actions if necessary. The NPRM also proposed to require the 
replacement of all affected support brackets. We are issuing this AD to 
address the defect of the aileron bellcrank support bracket, which, in 
the event of an aileron jam, could lead to failure of the support 
bracket and result in reduced controllability of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0103, dated April 30, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the

[[Page 63395]]

MCAI''), to correct an unsafe condition for all Saab AB, Saab 
Aeronautics Model SAAB 2000 airplanes. 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-2018-0797.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this final rule 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 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

    Saab AB, Saab Aeronautics has issued Saab Service Bulletin 2000-27-
056, dated April 18, 2018. This service information was incorporated by 
reference in AD 2018-11-07 on June 13, 2018 (83 FR 24399, May 29,

Costs of Compliance

    We estimate that this AD affects 8 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
              Labor cost                      Parts cost            Cost per product     Cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
Up to 19 work-hours x $85 per hour =   Up to $18,074..........  Up to $19,689..........  Up to $157,512.
 $1,615.
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data for the on-condition costs 
specified in this AD.

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

    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.
