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: The FAA is adopting a new airworthiness directive (AD) for all 
Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. This AD was 
prompted by reports of cracks in the o-ring groove of magnetic fuel 
level indicators. This AD requires a one-time detailed inspection of 
the magnetic fuel level indicator for cracks and replacement of cracked 
magnetic fuel level indicators. The FAA is issuing this AD to address 
the unsafe condition on these products.

DATES: This AD is effective October 31, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 31, 
2019.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2019-0053, dated March 14, 2019 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Saab AB, Saab Aeronautics Model 
SAAB 2000 airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Saab AB, Saab 
Aeronautics Model SAAB 2000 airplanes. The NPRM published in the 
Federal Register on July 3, 2019 (84 FR 31775). The NPRM was prompted 
by reports of cracks in the o-ring groove of magnetic fuel level 
indicators. The NPRM proposed to require a one-time detailed inspection 
of the magnetic fuel level indicator for cracks and replacement of 
cracked magnetic fuel level indicators.
    The FAA is issuing this AD to address cracks in the o-ring groove 
of magnetic fuel level indicators, which, if not detected and 
corrected, could result in a severe fuel leak and consequent risk of 
fuel starvation. See the MCAI for additional background information.

Comments

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

Conclusion

    The FAA 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. The FAA has 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 (Formerly Known as Saab AB, Saab 
Aerosystems) has issued Service Bulletin 2000-28-027, dated January 15, 
2019. This service information describes procedures for a one-time 
detailed inspection of the magnetic fuel level indicator for cracks and 
replacement of cracked magnetic fuel level indicators. 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

    The FAA estimates that this AD affects 11 airplanes of U.S. 
registry. The agency estimates the following costs to comply with this 
AD:

    The agency estimates the following costs to do any necessary on-
condition action that would be required based on the results of any 
required actions. The agency has no way of determining the number of 
aircraft that might need this on-condition 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.
    The FAA is 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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
