Discussion
The FAA issued AD 2019-21-08, Amendment 39-19774 (84 FR 59926, November 7, 2019), (``AD 2019-21-08''), for Textron Aviation Inc. (Textron) Models E33, E33A, E33C, F33, G33, 35-C33, 35-C33A, K35, M35, N35, P35, S35, V35, V35A, 36, and certain Models F33A, F33C, V35B, and A36 airplanes. AD 2019-21-08 required inspecting the right aileron flight control cable end fittings (terminal attachment fittings) and replacing any damaged cable assembly. AD 2019-21-08 resulted from reports of cracked and fractured right aileron flight control cable end fittings. The FAA issued AD 2019-21-08 to prevent failure of the right aileron flight control cable assembly, un-commanded right roll of the airplane, and loss of roll control in the left direction, which may lead to loss of control of the airplane.
Actions Since AD 2019-21-08 Was Issued
Since the FAA issued AD 2019-21-08, the FAA received a comment that AD 2019-21-08 should not apply to Models K35, M35, N35, and P35 airplanes. Textron verified those airplane models have a different configuration with the heating duct in a different location. The FAA has determined to supersede AD 2019-21-08 with this AD that retains all of the required actions from AD 2019-21-08 but removes airplane Models K35, M35, N35, and P35 from the applicability.
FAA's Determination
The FAA is issuing 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.
AD Requirements
This AD requires inspecting the right aileron flight control cable end fittings that thread into the turnbuckle for corrosion, pitting, and cracks and replacing any damaged cable assembly.
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 the quantity of recent reports of failure of the right aileron flight control cable end fittings necessitates that the corrective actions be accomplished within 30 days. 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 the FAA did not provide you with notice and an opportunity to provide your comments before it becomes effective. 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-2019-0959 andProduct Identifier 2019-CE-051-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 it 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 it receives about this final rule.
Costs of Compliance
The FAA estimates that this AD affects 3,161 airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts costproduct operators ---------------------------------------------------------------------------------------------------------------- Inspection of the right aileron 5 work-hours x $85 Not applicable............ $425 $1,343,425

The FAA estimates the following costs to do any necessary replacement that would be required based on the results of the inspection. The FAA has no way of determining the number of airplanes that might need this replacement:

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 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 small airplanes, gliders, balloons, airships, domestic business jet transport airplanes, and associated appliances to the Director of the Policy and Innovation Division.
Regulatory Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5U.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.
