SUPPLEMENTARY INFORMATION:

Discussion

    The FAA received a report that, on May 26, 2019, a Textron Model 
T210M airplane experienced an in-flight break-up while performing low-
altitude aerial survey operations in Australia. The carry-thru spar 
failed and resulted in wing separation and loss of control of the 
airplane. A visual examination of the fracture surface identified 
fatigue cracking that initiated at a corrosion pit. The FAA issued an 
airworthiness concern sheet (ACS) on June 27, 2019, advising owners and 
operators of the accident and requesting relevant information about the 
fleet.
    Following the ACS, the FAA received reports of widespread and 
severe corrosion of the carry-thru spar on Models 210G, T210G, 210H, 
T210H, 210J, T210J, 210K, T210K, 210L, T210L, 210M, and T210M 
airplanes. Further investigation identified that these early model 
airplanes were manufactured without corrosion protection or primer, 
increasing their susceptibility to corrosion. Additionally, the design 
of these early model airplanes, where the upper surface of the spar is 
exposed to the environment, allows a pathway for moisture intrusion. 
Model 210-series airplanes were also delivered with foam installed 
along the carry-thru spar lower cap. The foam traps moisture against 
the lower surface of the carry-thru spar cap, which can increase the 
development of corrosion.
    Corrosion of the carry-thru spar lower cap can lead to fatigue 
cracking or reduced structural strength of the carry-thru spar, which 
could result in separation of the wing and loss of airplane control. 
The FAA is issuing this AD to address the unsafe condition on these 
products.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Textron Aviation Mandatory Single Engine Service 
Letter SEL-57-08, Revision 1, dated November 19, 2019 (SEL-57-08 R1). 
This service information contains instructions for visually inspecting 
the carry-thru spar for corrosion, damage, and cracks and for 
completing an eddy current inspection. This service information also 
specifies applying protective coating and CIC.
    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.

Other Related Service Information

    The FAA reviewed Textron Aviation Mandatory Single Engine Service 
Letter SEL-57-08, dated November 1, 2019, which contains the same 
instructions and repair criteria as SEL-57-08 R1.
    The FAA also reviewed Textron Aviation Mandatory Single Engine 
Service Letter SEL-57-06, dated June 24, 2019, and Textron Aviation 
Mandatory Single Engine Service Letter SEL-57-06, Revision 1, dated 
November 19, 2019. This service information contains instructions for 
visually inspecting the carry-thru spar for corrosion and doing an eddy 
current inspection of the carry-thru spar regardless of whether 
corrosion is found and removed. This service information also contains 
instructions for applying CIC, but does not specify applying protective 
coating.

FAA's Determination

    The FAA is issuing this AD because the FAA evaluated all the 
relevant information and determined the unsafe condition described 
previously is likely to exist or develop in other products of the same 
type design.

[[Page 10044]]

AD Requirements

    This AD requires accomplishing the actions specified in SEL-57-08 
R1 with the exception of the differences discussed in the Differences 
Between the AD and the Service Information section located below. This 
AD also requires reporting the inspection results to the FAA by email 
at [email protected].

Differences Between the AD and the Service Information

    <bullet> Although Textron SEL-57-08 R1 also applies to Models 210N, 
P210N, T210N, 210R, P210R, and T210R airplanes, this AD does not. 
Models 210N, P210N, T210N, 210R, P210R, and T210R airplanes were 
manufactured with corrosion protection. While the spars on these models 
are subject to corrosion, the reports the FAA has received indicate the 
corrosion is not as widespread or severe as on the earlier models 
manufactured without corrosion protection. Therefore, the FAA has 
determined to not include Models 210N, P210N, T210N, 210R, P210R, and 
T210R airplanes in this immediate AD action; however, the FAA may take 
AD action that applies to these models in the future.
    <bullet> Textron SEL-57-08 R1 allows up to 12 months to comply with 
the actions in the service letter. Due to the widespread and severe 
corrosion affecting a substantial number of airplanes, this AD requires 
compliance no later than 60 days after the effective date of this AD.
    <bullet> Textron SEL-57-08 R1 specifies inspecting all interior 
surfaces of the carry-thru spar, while this AD only requires inspecting 
the carry-thru spar lower cap, including the lower surface, edge, and 
upper surface of the lower cap. While the web and upper cap of the 
carry-thru spar may be susceptible to corrosion, evidence does not 
support including inspection of these areas as part of this AD. The FAA 
will continue to monitor reports of corrosion on all areas of the 
carry-thru spar for potential future action.
    <bullet> Textron SEL-57-08 R1 does not require an eddy current 
inspection on the carry-thru spar unless the amount of material removed 
in the blended area exceeds 0.010 inch deep but is within limits. This 
AD requires eddy current inspection of all locations on the carry-thru 
spar where corrosion was removed. The fatigue crack on the Model T210M 
airplane that suffered the in-flight break-up initiated from a 
corrosion pit approximately 0.011 inch deep in the lower cap kick area. 
The less restrictive eddy current inspection requirements specified in 
SEL-57-08 R1 could potentially miss similar fatigue cracks on airplanes 
currently operating in the field.
    <bullet> Textron SEL-57-08 R1 only requires an eddy current 
inspection of the lower cap kick of the carry-thru spar if corrosion is 
identified on the carry-thru spar cap. This AD requires a one-time eddy 
current inspection of the lower cap kick area of all affected 
airplanes, regardless of the results of the visual inspection. The 
fatigue crack on the Model T210M airplane that suffered the in-flight 
break-up initiated in the lower cap kick area. Cracks and corrosion 
damage may be difficult to identify through visual inspection alone. 
The FAA will use the results of the one-time eddy current inspection of 
the lower cap kick area, in part, to determine the necessity of future 
rulemaking action.
    <bullet> Textron SEL-57-08 R1 specifies contacting Textron for 
evaluation and disposition of certain damage. Instead, this AD requires 
removing the carry-thru spar from service or repairing it (if possible) 
in accordance with the AMOC procedures identified in paragraph (o) of 
this AD. Operators should work with Textron to develop a repair in 
support of an AMOC request.
    <bullet> Textron SEL-57-08 R1 provides instruction allowing 
airplanes that have complied with SEL-57-06 to complete the application 
of the protective coating and CIC within 200 flight hours or at the 
next annual inspection, whichever occurs first. This AD permits those 
airplanes that have complied with the visual and eddy current 
inspections in SEL-57-06, as required in paragraphs (g) and (h) of this 
AD, to complete the application of the protective coating and CIC 
within 12 months from the date of the visual and eddy current 
inspections.

Interim Action

    The FAA considers this AD interim action. This AD requires a one-
time visual inspection of specified areas on the carry-thru spar lower 
cap and an eddy current inspection of the lower cap kick area and any 
locations where corrosion was removed. This AD also requires reporting 
the inspection results to the FAA. The FAA will analyze the inspection 
results received to determine further rulemaking action.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because of a severe and widespread corrosion issue affecting the carry-
thru spar lower cap on some Textron Model 210-series airplanes. As of 
January 29, 2020, Textron has received 194 inspection reports on Models 
210G, T210G, 210H, T210H, 210J, T210J, 210K, T210K, 210L, T210L, 210M, 
and T210M airplanes. Of these 194 reports, 96 airplanes have reported 
corrosion (49 percent) with 18 of those reports (9 percent) resulting 
in removing the carry-thru spar from service. The corrosion observed 
included several instances of exfoliation corrosion and stress 
corrosion cracking. The FAA has determined that the large number of 
corrosion reports and the severity of the corrosion identified on a 
critical single load path part necessitate issuance of an immediately 
adopted rule. If the corrosion initiates a fatigue crack or affects the 
carry-thru spar's ability to support the required structural loads, the 
airplane may suffer a catastrophic failure. Therefore, the FAA finds 
good cause that notice and opportunity for prior public comment are 
impracticable. In addition, for the reasons stated above, the FAA finds 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, the FAA invites you to send any written data, views, 
or arguments about this final rule. Send your comments to an address 
listed under the ADDRESSES section. Include the Docket Number FAA-2020-
0156 and Product Identifier 2019-CE-053-AD at the beginning of your 
comments. The FAA specifically invites comments on the overall 
regulatory, economic, environmental, and energy aspects of this final 
rule. The FAA will consider all comments received by the closing date 
and may amend this final rule because of those comments.
    The FAA will post all comments the FAA receives, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The FAA will also post a report summarizing each substantive 
verbal contact the FAA receives about this final rule.

Costs of Compliance

    The FAA estimates that this AD affects 1,520 airplanes of U.S. 
registry.
    The FAA estimates the following costs to comply with this AD:

    The FAA estimates the following costs to do any necessary repairs 
based on the results of the inspection. The FAA has no way of 
determining the number of airplanes that might need these repairs:

                                               On-Condition Costs

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

    The amount of work-hours necessary to complete the eddy current 
inspection and remove the corrosion will depend on the extent of the 
corrosion on the spar. The FAA has no way of estimating the work-hours 
that may be required for those procedures. The FAA's cost estimate 
assumes a minimum of one hour for the eddy current inspection and two 
hours for the corrosion removal. Replacement spars are not currently 
available from Textron. Textron no longer produces the current spar 
design, and they are working to develop a new spar design. The FAA does 
not have data to determine the availability of replacement spars from 
other sources.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to be 
approximately 2 hours per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, completing and reviewing the collection of 
information. All responses to this collection of information are 
mandatory. Send comments regarding this burden estimate or any other 
aspect of this collection of information, including suggestions for 
reducing this burden to: Information Collection Clearance Officer, 
Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 
76177-1524.

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 Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because FAA has determined 
that it has good cause to adopt this rule without notice and comment, 
RFA analysis is not required.

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, and
    (2) Will not affect intrastate aviation in Alaska.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2020-03-16 Textron Aviation Inc. (type certificate previously held 
by Cessna Aircraft Company): Amendment 39-21029; Docket No. FAA-
2020-0156; Product Identifier 2019-CE-053-AD.

(a) Effective Date

    This AD is effective March 9, 2020.

[[Page 10046]]

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Textron Aviation Inc. (type certificate 
previously held by Cessna Aircraft Company) Models 210G, T210G, 
210H, T210H, 210J, T210J, 210K, T210K, 210L, T210L, 210M, and T210M

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 5310, Fuselage Main, Structure.

(e) Unsafe Condition

    This AD was prompted by the in-flight break-up of a Model T210M 
airplane due to fatigue cracking of the carry-thru spar that 
initiated at a corrosion pit and subsequent reports of other Model 
210-series airplanes with widespread and severe corrosion. The FAA 
is issuing this AD to detect and correct cracks, corrosion, and 
other damage of the carry-thru spar lower cap, which, if not 
corrected, could lead to the carry-thru spar being unable to support 
the required structural loads and could result in separation of the 
wing and loss of airplane control.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Visual Inspection

    Within 60 days after March 9, 2020 (the effective date of this 
AD) or within the next 20 hours time-in-service (TIS) after March 9, 
2020 (the effective date of this AD), whichever occurs first, 
prepare the carry-thru spar lower cap for inspection by following 
steps 4 and 5 of the Accomplishment Instructions in Textron Aviation 
Mandatory Single Engine Service Letter SEL-57-08, Revision 1, dated 
November 19, 2019 (SEL-57-08 R1). Visually inspect the carry-thru 
spar lower cap (including the lower surface, upper surface, and 
edge) with a 10X magnification lens looking for corrosion, cracks, 
and damage. You are not required to inspect the lower cap to web 
radius, spar web, or upper cap. Refer to the `Spar Dimensions' 
figure on page 6 and the `Spar Detail' figure on page 7 of SEL-57-08 
R1 for the location of the specific spar features.
    (1) If there is a crack, before further flight, remove the 
carry-thru spar from service.
    (2) If there is damage or evidence of previous removal of 
corrosion (blending), before further flight, either remove the 
carry-thru spar from service or repair the area using a method 
approved as specified in paragraph (o) of this AD. Comply with the 
requirements in paragraph (h) of this AD before further flight.
    (3) If there is any corrosion, before further flight, remove the 
corrosion in the affected area by following steps 6.B.(1) through 
(7) of the Accomplishment Instructions in SEL-57-08 R1 and then 
mechanically measure the depth of the blended area using a straight 
edge and feeler gauge or a depth gauge micrometer.
    (i) If the material removed in the blended area exceeds the 
allowable blend limits specified in table 1 (including the notes) of 
SEL-57-08 R1, before further flight, either remove the carry-thru 
spar from service or repair the area using a method approved as 
specified in paragraph (o) of this AD. Comply with the requirements 
in paragraph (h) of this AD before further flight.
    (ii) If the material removed in the blended area does not exceed 
the allowable blend limits specified in table 1 (including the 
notes) of SEL-57-08 R1, comply with the requirements in paragraph 
(h) of this AD before further flight.
    (4) If the visual inspection did not detect corrosion, cracks, 
or damage and there is no evidence of previous removal of corrosion, 
comply with the requirements in paragraph (h) of this AD before 
further flight.

(h) Eddy Current Inspection

    (1) Complete an eddy current inspection of the carry-thru spar 
lower cap for cracks, corrosions, and damage in the following areas 
in accordance with step 7 of the Accomplishment Instructions in SEL-
57-08 R1.
    (i) The kick area as depicted in the `Spar Dimensions' figure on 
page 6 of SEL-57-08 R1. You must complete an eddy current inspection 
of the lower cap kick area of your airplane regardless of whether 
corrosion was found as a result of the visual inspection in 
paragraph (g) of this AD.
    (ii) All areas where corrosion was found and removed as a result 
of the inspection in paragraph (g) of this AD.
    (2) If there is a crack, before further flight, remove the 
carry-thru spar from service.
    (3) If there is any damage, before further flight, either remove 
the carry-thru spar from service or repair the area using a method 
approved as specified in paragraph (o) of this AD. After completing 
the repair, repeat the eddy current inspection of the repaired area 
before further flight.
    (4) If there is any corrosion, before further flight, remove the 
corrosion by following the requirements in paragraph (g)(3) of this 
AD. You must repeat the eddy current inspection and comply with 
paragraph (h) of this AD for the area where the additional material 
was removed, but you do not have to repeat the eddy current 
inspection of the kick area.

(i) Corrosion Protection

    Before further flight after completing the eddy current 
inspection in paragraph (h) of this AD, apply protective coating and 
corrosion inhibiting compound (CIC) by following steps 9 and 10 of 
the Accomplishment Instructions in SEL-57-08 R1.

(j) Installation Prohibition

    As of March 9, 2020 (the effective date of this AD), do not 
install on any airplane a carry-thru spar unless it has been 
inspected as required by paragraphs (g) and (h) of this AD and 
corrosion protection applied as required by paragraph (i).

(k) Reporting Requirement

    Within 10 days after completing the inspections required by this 
AD or within 10 days after March 9, 2020 (the effective date of this 
AD), whichever occurs later, report to the FAA by email ([email protected]) all information requested in the Carry-Thru Spar 
Inspection Report Attachment to SEL-57-08 R1.

(l) Credit for Previous Actions

    (1) You may take credit for the visual inspection required by 
paragraph (g) of this AD if you performed the visual inspection
