SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a supplemental notice of proposed rulemaking (SNPRM) 
to amend 14 CFR part 39 by adding an AD that would apply to certain 
serial-numbered Textron Aviation Inc. (Textron) (type certificate 
previously held by Cessna Aircraft Company) Model 172N, 172P, 172Q, 
172RG, F172N, F172P, FR172K, R172K, 182E,

[[Page 63196]]

182F, 182G, 182H, 182J, 182K, 182L, 182M, 182N, 182P, 182Q, 182R, T182, 
F182P, F182Q, FR182, R182, TR182, 206, P206, P206A, P206B, P206C, 
P206D, P206E, TP206A, TP206B, TP206C, TP206D, TP206E, U206, U206A, 
U206B, U206C, U206D, U206E, U206F, U206G, TU206A, TU206B, TU206C, 
TU206D, TU206E, TU206F, TU206G, 207, 207A, T207, T207A, 210-5 (205), 
210-5A (205A), 210B, 210C, 210D, 210E, 210F, and T210F airplanes. The 
SNPRM published in the Federal Register on May 29, 2020 (85 FR 32308).
    The FAA preceded the SNPRM with a notice of proposed rulemaking 
(NPRM) that published in the Federal Register on February 1, 2018 (83 
FR 4605). The NPRM was prompted by reports of cracks in the lower area 
of the forward cabin doorpost bulkhead on more than four dozen Textron 
100 and 200 airplanes. The NPRM proposed to require repetitively 
inspecting the lower area of the forward cabin doorposts at the strut 
attach fitting for cracks and repairing any cracks found by modifying 
the area with the applicable service kit. The SNPRM proposed to modify 
the estimated costs of the proposed AD, the repetitive inspection 
intervals, and the credit allowed for previous actions; clarify the 
inspection instructions for airplanes with the service kit installed; 
correct the contact information for obtaining the service information; 
and add a reporting requirement to collect the inspection results. The 
SNPRM also changed some of the model designations listed in the 
applicability in order to match the models as they are listed in the 
type certificate data sheet.
    The FAA is issuing this AD to detect and address cracking of the 
wing strut attach point. The unsafe condition, if not addressed, could 
result in failure of the wing in operation, which could result in loss 
of control of the airplane.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comments 
received on the SNPRM and the FAA's response to each comment.

Support for the SNPRM

    Patrick Imperatrice expressed support for the proposed AD.

Request To Extend or Remove Calendar Compliance Time

    Kermit Bunde expressed support for the 1,000-hour time-in-service 
(TIS) inspection interval but requested the FAA remove the 36-month 
calendar time inspection interval. The commenter stated that the 36-
month interval is too often and that cracking is a function of usage 
and not only elapsed time. The commenter provided examples of Cessna 
maintenance actions that have no calendar time limit.
    The FAA disagrees. Both the manufacturer's guidance, which is 
published in the supplemental inspection documents (SIDs) for certain 
airplanes, and fleet history support the 36-month interval for 
inspecting this location. Loading conditions outside of flight, such as 
ground loads, handling loads, and tie down loads, may also cause 
cracking at this location. Therefore, the FAA determined the inspection 
interval of 36 calendar months or 1,000 hours TIS, whichever occurs 
first, is necessary to address the unsafe condition. The FAA did not 
change this AD based on this comment.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Cessna Single Engine Service Bulletin SEB93-5, 
Revision 2, dated May 29, 2019 (SEB93-5R2) and Cessna Single Engine 
Service Bulletin SEB95-19, dated December 29, 1995 (SEB95-19). For the 
applicable model airplanes, the service information contains procedures 
for repetitively inspecting the lower area of the forward cabin 
doorposts for cracks and repairing any cracks found by modifying the 
area with the applicable Cessna service kit.
    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 Cessna Single Engine Service Kit SK172-147, dated 
December 29, 1995. This service kit provides instructions to add a 
channel to each forward cabin doorpost bulkhead. The FAA also reviewed 
Cessna Single Engine Service Kit SK182-115, dated December 29, 1995; 
Cessna Single Engine Service Kit SK206-42D, dated May 29, 2019; and 
Cessna Single Engine Service Kit SK210-156, dated December 29, 1995. 
For the applicable model airplanes, these service kits provide 
instructions to add a doubler and a channel to each forward cabin 
doorpost bulkhead. In addition, the FAA reviewed Cessna Single Engine 
Service Kit SK207-19A, dated May 29, 2019. The service information 
contains procedures to reinforce the lower forward doorpost bulkhead 
and wing strut fitting by adding a doubler and a channel to each 
forward cabin doorpost bulkhead.

Costs of Compliance

    The FAA estimates that this AD affects 14,653 airplanes of U.S. 
registry.
    The FAA estimates the following costs to comply with 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.
    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

    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.
