Airworthiness Directives; Saab AB, Support and Services (Formerly 
Known as Saab AB, Saab Aeronautics) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Saab AB, Support and Services Model SAAB 2000 airplanes. This 
proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. This proposed AD 
would require revising the existing maintenance or inspection program, 
as applicable, to incorporate new or more restrictive airworthiness 
limitations, as specified in a European Union Aviation Safety Agency 
(EASA) AD, which will be incorporated by reference. The FAA is 
proposing this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by March 2, 
2020.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0263, dated October 22, 2019 
(``EASA AD 2019-0263'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Saab AB, Support and Services Model SAAB 2000 
airplanes.
    This proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
proposing this AD to address, among other things, fatigue cracking of 
principal structural elements (PSEs) and corrosion prevention and 
control. This unsafe condition, if not addressed, could result in 
reduced structural integrity of a PSE and lead to loss of control of 
the airplane. See the MCAI for additional background information.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0263 describes airworthiness limitations for safe life 
limits, structural limitation items, and fuel airworthiness items, as 
well as certification maintenance requirements.
    This material 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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the FAA's bilateral agreement with the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD because the FAA 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Proposed AD Requirements

    This proposed AD would require revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations, which are specified in EASA AD 
2019-0263 described previously, as incorporated by reference. Any 
differences with EASA AD 2019-0263 are identified as exceptions in the 
regulatory text of this AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections) and 
Critical Design Configuration Control Limitations (CDCCLs). Compliance 
with these actions and CDCCLs is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(j)(1) of this proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2019-0263 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2019-0263 in its 
entirety, through that incorporation, except for any differences 
identified as exceptions in the regulatory text of this proposed AD. 
Using common terms that are the same as the heading of a particular 
section in the EASA AD does not mean that operators need comply only 
with that section. For example, where the AD requirement refers to 
``all required actions and compliance times,'' compliance with this AD 
requirement is not limited to the section titled ``Required Action(s) 
and Compliance Time(s)'' in the EASA AD.

[[Page 2913]]

    Service information specified in EASA AD 2019-0263 that is required 
for compliance with EASA AD 2019-0263 will be available on the internet 
at https://www.regulations.gov by searching for and locating Docket No. 
FAA-2019-1073 after the FAA final rule is published.

Airworthiness Limitation ADs Using the New Process

    The FAA's new process, which uses MCAI ADs as the primary source of 
information for compliance with corresponding FAA ADs, has been limited 
to certain MCAI ADs (primarily those with service bulletins as the 
primary source of information for accomplishing the actions required by 
the FAA AD). However, the FAA is now expanding the process to include 
MCAI ADs that specify the incorporation of airworthiness limitation 
documents.
    Although the format of the airworthiness limitation ADs using the 
new process is different than the FAA's existing format for 
airworthiness limitation ADs, the FAA requirements are the same: 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document.
    The previous format of the airworthiness limitation ADs included a 
paragraph that specified that no alternative actions (e.g., 
inspections), intervals, or CDCCLs may be used unless the actions, 
intervals, and CDCCLs are approved as an alternative method of 
compliance (AMOC) in accordance with the procedures specified in the 
AMOCs paragraph under ``Other FAA Provisions.'' This new format 
includes a ``New Provisions for Alternative Actions, Intervals, and 
CDCCLs'' paragraph that does not specifically refer to AMOCs, but 
operators may still request an AMOC to use an alternative action, 
interval, or CDCCL.

Costs of Compliance

    The FAA estimates that this proposed AD affects 11 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:
    The FAA has determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although the 
agency recognizes that this number may vary from operator to operator. 
In the past, the agency has estimated that this action takes 1 work-
hour per airplane. Since operators incorporate maintenance or 
inspection program changes for their affected fleet(s), the FAA has 
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, the agency estimates the average total 
cost per operator to be $7,650 (90 work-hours x $85 per work-hour).

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 proposed 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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (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.

paragraph (3) of EASA AD 2019-0263 is at the applicable ``associated 
thresholds'' specified in paragraph (3) of EASA AD 2019-0263, or 
within 90 days after the effective date of this AD, whichever occurs 
later.
    (4) The provisions specified in paragraphs (4) and (5) of EASA 
AD 2019-0263 do not apply to this AD.
    (5) The ``Remarks'' section of EASA AD 2019-0263 does not apply 
to this AD.

(i) New Provisions for Alternative Actions, Intervals, and Critical 
Design Configuration Control Limitations (CDCCLs)

    After the maintenance or inspection program has been revised as 
required by paragraph (g) of this AD, no alternative actions (e.g., 
inspections), intervals, and CDCCLs are allowed except as specified 
in the provisions of the ``Ref. Publications'' section of EASA AD 
2019-0263.

(j) Other FAA AD Provisions
