The FAA proposes to supersede Airworthiness Directive (AD) 2020–07–17, which applies to all Saab AB, Support and Services Model SAAB 2000 airplanes. AD 2020–07–17 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2020–07–17, the FAA has determined 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 is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products. Comments Invited The FAA must receive comments on this proposed AD by November 18, 2021. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA issued AD 2020–07–17, Amendment 39–19896 (85 FR 21764, April 20, 2020) (AD 2020–07–17), for all Saab AB, Support and Services Model SAAB 2000 airplanes. AD 2020–07–17 corresponds to EASA AD 2019–0263, dated October 22, 2019 (EASA AD 2019–0263). AD 2020–07–17 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA E:\FR\FM\04OCP1.SGM 04OCP1 54664 Federal Register / Vol. 86, No. 189 / Monday, October 4, 2021 / Proposed Rules issued AD 2020–07–17 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. Actions Since AD 2020–07–17 Was Issued Since the FAA issued AD 2020–07– 17, the FAA has determined that new or more restrictive airworthiness limitations are necessary, and revised (fatigue) life limits for various parts are also necessary. EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0132, dated May 25, 2021 (EASA AD 2021– 0132) (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. EASA AD 2021–0132 superseded EASA AD 2019–0263. 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 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 Service Information Under 1 CFR Part 51 EASA AD 2021–0132 describes new or more restrictive airworthiness limitations for safe life limits, structural limitation items, and fuel airworthiness items, as well as certification maintenance requirements. This AD would also require EASA AD 2019–0263, which the Director of the Federal Register approved for incorporation by reference as of May 26, 2020 (85 FR 21764, April 20, 2020). 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 VerDate Sep<11>2014 17:56 Oct 01, 2021 Jkt 256001 described in the MCAI referenced above. The FAA is proposing this AD because the FAA has 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 retain the requirements of AD 2020–07–17. This proposed AD would also require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, which are specified in EASA AD 2021–0132 described previously, as incorporated by reference. Revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations required by this AD terminates the requirements of AD 2020–07–17. Any differences with EASA AD 2021–0132 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 (m)(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 developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate EASA AD 2021–0132 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2021–0132 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 EASA AD 2021–0132 does not mean PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 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 EASA AD 2021–0132. Service information required by EASA AD 2021–0132 for compliance will be available at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0841 after the FAA final rule is published. Airworthiness Limitation ADs Using the New Process The FAA’s process of incorporating by reference 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 require a change to airworthiness limitation documents, such as airworthiness limitation sections. For these ADs that incorporate by reference an MCAI AD that changes airworthiness limitations, the FAA requirements are unchanged. Operators must revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in the new airworthiness limitation document. The airworthiness limitations must be followed according to 14 CFR 91.403(c) and 91.409(e). 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 9 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: The FAA estimates the total cost per operator for the retained actions from E:\FR\FM\04OCP1.SGM 04OCP1 Federal Register / Vol. 86, No. 189 / Monday, October 4, 2021 / Proposed Rules AD 2020–07–17 to be $7,650 (90 workhours × $85 per work-hour). The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although the agency recognizes that this number may vary from operator to operator. 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. The FAA estimates the total cost per operator for the new proposed maintenance/inspection program revision to be $7,650 (90 work-hours × $85 per work-hour). 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. 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) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. 17:56 Oct 01, 2021 Jkt 256001 The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by: a.

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 supersede Airworthiness Directive (AD) 
2020-07-17, which applies to all Saab AB, Support and Services Model 
SAAB 2000 airplanes. AD 2020-07-17 requires revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations. Since the FAA issued AD 
2020-07-17, the FAA has determined 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 
is proposed for incorporation 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 November 
18, 2021.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:
     Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow the instructions for submitting comments.

Background

    The FAA issued AD 2020-07-17, Amendment 39-19896 (85 FR 21764, 
April 20, 2020) (AD 2020-07-17), for all Saab AB, Support and Services 
Model SAAB 2000 airplanes. AD 2020-07-17 corresponds to EASA AD 2019-
0263, dated October 22, 2019 (EASA AD 2019-0263). AD 2020-07-17 
requires revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive airworthiness 
limitations. The FAA

[[Page 54664]]

issued AD 2020-07-17 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.

Actions Since AD 2020-07-17 Was Issued

    Since the FAA issued AD 2020-07-17, the FAA has determined that new 
or more restrictive airworthiness limitations are necessary, and 
revised (fatigue) life limits for various parts are also necessary.
    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0132, dated May 25, 2021 (EASA 
AD 2021-0132) (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. EASA 
AD 2021-0132 superseded EASA AD 2019-0263.
    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 
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 Service Information Under 1 CFR Part 51

    EASA AD 2021-0132 describes new or more restrictive airworthiness 
limitations for safe life limits, structural limitation items, and fuel 
airworthiness items, as well as certification maintenance requirements.
    This AD would also require EASA AD 2019-0263, which the Director of 
the Federal Register approved for incorporation by reference as of May 
26, 2020 (85 FR 21764, April 20, 2020).
    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 has 
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 retain the requirements of AD 2020-07-17. 
This proposed AD would also require revising the existing maintenance 
or inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations, which are specified in EASA AD 
2021-0132 described previously, as incorporated by reference. Revising 
the existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations required 
by this AD terminates the requirements of AD 2020-07-17. Any 
differences with EASA AD 2021-0132 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 
(m)(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 developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate EASA AD 2021-0132 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2021-0132 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 EASA AD 2021-0132 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 EASA AD 2021-
0132. Service information required by EASA AD 2021-0132 for compliance 
will be available at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2021-0841 after the FAA final rule is 
published.

Airworthiness Limitation ADs Using the New Process

    The FAA's process of incorporating by reference 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 require a change to airworthiness 
limitation documents, such as airworthiness limitation sections.
    For these ADs that incorporate by reference an MCAI AD that changes 
airworthiness limitations, the FAA requirements are unchanged. 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document. The airworthiness limitations must 
be followed according to 14 CFR 91.403(c) and 91.409(e).
    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 9 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 
proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from

[[Page 54665]]

AD 2020-07-17 to be $7,650 (90 work-hours x $85 per work-hour).
    The FAA has determined that revising the existing 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. 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. The FAA estimates the total cost per operator for the new 
proposed maintenance/inspection program revision 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.

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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
