Airworthiness Directives; Textron Aviation Inc. 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 Textron Aviation Inc. (Textron) Models 180, 180A, 180B, 180C, 
180D, 180E, 180F, 180G, 180H, 180J, 180K, 182, 182A, 182B, 182C, 182D, 
185, 185A, 185B, 185C, 185D, 185E, A185E, and A185F airplanes. This 
proposed AD was prompted by a report of cracks found in the tailcone 
and horizontal stabilizer attachment structure. This proposed AD would 
require inspecting the tailcone and horizontal stabilizer for corrosion 
and cracks and repairing or replacing damaged parts as necessary. The 
FAA is proposing this AD to address the unsafe condition on these 
products.

[[Page 28891]]

summarizing each substantive verbal contact received about this NPRM.

Discussion

    The FAA received a report of cracks in the tailcone and horizontal 
stabilizer attachment structure on a Textron (type certificate 
previously held by Cessna Aircraft Company) Model 185 airplane. It was 
observed during maintenance that the horizontal stabilizer tail section 
moved up and down and had excessive play. After a detailed inspection, 
the tailcone reinforcement braces were found cracked on both sides of 
the airplane. Upon further investigation, the FAA discovered similar 
conditions on 29 additional Textron 180 and 185 series airplanes. The 
FAA determined that the combination of the attachment structure design 
and high loads during landing contribute to the development of cracks 
in the tailcone and horizontal stabilizer attachment structure. This 
condition, if unaddressed, could result in failure of the horizontal 
stabilizer to tailcone attachment and lead to tail separation with 
consequent loss of control of the airplane.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Textron Aviation Single Engine Mandatory Service 
Letter SEL-55-01, dated December 7, 2017. The service information 
contains procedures for inspecting the stabilizer hinge brackets, 
tailcone reinforcement angles, corner reinforcements, stabilizer hinge 
reinforcement channel, stabilizer hinge assemblies, stabilizer aft spar 
reinforcement, and the lower half of the stabilizer aft spar from 
station (STA) 16 on the left side of the stabilizer aft spar to STA 16 
on the right side for cracks and corrosion. 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.

FAA's Determination

    The FAA is proposing this AD because it 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.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Differences Between This Proposed AD and the Service Information

    The service information applies to airplanes with more than 3,000 
total hours time-in-service or 10 years in service, while this proposed 
AD would apply regardless of the airplane's time-in-service. This 
proposed AD would require inspecting for and replacing loose or sheared 
rivets, which is not specified in the service information.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 6,586 
airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs

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

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
proposed inspection. The FAA has no way of determining the number of 
aircraft that might need these actions:

    Since corrosion may affect any or all of the parts subject to the 
inspection in this proposed AD differently and the severity of the 
corrosion on each part would affect the time necessary to correct the 
condition, the FAA has no way to determine an overall cost per product 
for removing the corrosion. Similarly, loose or sheared rivets may also 
affect any or all of the parts subject to the inspection in this 
proposed AD differently, and the time necessary to correct the 
condition on each product would be different. Therefore, the FAA has no 
way to determine an overall cost

[[Page 28892]]

per product for replacing loose or sheared rivets.

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) 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

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

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Textron Aviation Inc.: Docket No. FAA-2020-0472; Product Identifier 
2018-CE-060-AD.

(e) Unsafe Condition

    This AD was prompted by a report of cracks found in the tailcone 
and horizontal stabilizer attachment structure. The FAA is issuing 
this AD to detect and correct corrosion and cracks in the tailcone 
and horizontal stabilizer attachment structure. The unsafe 
condition, if not addressed, could result in failure of the 
horizontal stabilizer to tailcone attachment, which could lead to 
tail separation with consequent loss of control of the airplane.

(f) Compliance

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

(g) Inspect, Repair, and Replace

    Within the next 100 hours time-in-service (TIS) after the 
effective date of this AD or within the next 12 months after the 
effective date of this AD, whichever occurs later, and thereafter 
every 500 hours TIS or 5 years, whichever occurs first, visually 
inspect each stabilizer hinge bracket, tailcone reinforcement angle, 
corner reinforcement, stabilizer hinge reinforcement channel, 
stabilizer hinge assembly, stabilizer aft spar reinforcement, and 
the lower half of the stabilizer aft spar from station (STA) 16 on 
the left side to STA 16 on the right side for corrosion and cracks; 
remove any corrosion; and replace any part with a crack by following 
the Accomplishment Instructions, paragraphs 9 through 11 and 13, of 
Textron Aviation Single Engine Mandatory Service Letter SEL-55-01, 
dated December 7, 2017. Also inspect for loose rivets and sheared 
rivets. If there is a loose or sheared rivet, before further flight, 
replace the rivet.

    Actions accomplished before the effective date of this AD within 
the previous 5 years or 500 hours TIS, whichever was the most 
recent, in accordance with the procedures specified in the documents 
listed in paragraphs (h)(i) through (viii) of this AD as applicable 
to your airplane are considered acceptable for compliance with the 
corresponding actions in paragraph (g) of this AD. The time between 
any inspection for which credit is allowed by this paragraph and the 
next inspection accomplished in accordance with paragraph (g) of 
this AD must not exceed 500 hours TIS or 5 years, whichever occurs
