FAAs Justification and Determination of the Effective Date Section 553b3B of the Administrative Procedure Act 5 U.S.C.
authorizes agencies to dispense with notice and comment procedures for rules when the agency, for good cause finds that those procedures are impracticable, unnecessary, or contrary to the public interest. Under this section, an agency, upon finding good cause, may issue a final rule without seeking comment prior to the rulemaking.
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 an initial action is required within 30 hours TIS, which could equate to 1 month in these high usage rotorcraft; and corrective action, if necessary, is required before further flight. Therefore, notice and opportunity for prior public comment are impracticable and contrary to public interest pursuant to 5 U.S.C.
553b3B. In addition, for the reasons stated above, the FAA finds that good cause exists pursuant to 5 U.S.C. 553d for making this amendment effective in less than 30 days.
Authority for This Rulemaking Title 49 of the United States Code specifies the FAAs 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 Agencys 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.

f Required Actions Within 30 hours time-in-service after the effective date of this AD:
1 Inspect the upper rail of each right hand RH and left hand LH door for parallelism, deformation, corrosion, and cracking. If necessary, adjust the sliding door, ensuring that the parallelism between the sliding door and its frame does not exceed 1.5 mm .059
in on a length of 1,200 mm 47.24 in. The frame includes the sliding door, the overhead panel, and the two rear bulkheads. Repair or replace the upper rail before further flight if there is any deformation, corrosion, or cracking.
2 With the sliding door removed, inspect the front roller to determine if it is below the minimum diameter of 17.5 mm 0.69 in, below the minimum height of 17 mm 0.67
in, if it has any corrosion or flat spot, and to determine if it is correctly installed per Figure 1 of Airbus Alert Service Bulletin ASB No. AS35052.00.54 or ASB No.
AS35552.00.32, each at Revision 1 and dated July 30, 2020, as applicable to your helicopter model. If the front roller is below the minimum diameter, below the minimum height, or has any flat spot or corrosion, before further flight, remove the front roller from service. If the front roller was not correctly installed, reinstall it correctly before further flight.
