Federal Register / Vol. 86, No. 184 / Monday, September 27, 2021 / Rules and Regulations
The FAA issued AD 20211602 to address incorrect locking of the LH side stairway door, which could result in an in-flight opening of the door and subsequent damage to the helicopter or injury to persons on the ground. See EASA AD 20200087 for additional background information.
Actions Since AD 20211602 Was Issued Since AD 20211602 was issued, the FAA has determined that is necessary to clarify a required exception. As published, paragraph h7 of AD 2021
1602 could cause confusion with paragraph h5 of AD 20211602.
Paragraph h7 of this AD clarifies that the terminating action for the repetitive inspections as required by paragraph 2
of EASA AD 20200087 does not apply to this AD. The repetitive inspections as required by paragraph 2 of EASA AD
20200087 are not required by paragraph h5 of this AD, and accordingly, this AD cannot provide terminating action for those repetitive inspections.

EASA AD 20200087 requires repetitively inspecting the locking safety mechanism of the LH side stairway door handle for correct operation and depending on the results, reconditioning the locking safety mechanism or contacting the Airbus Helicopters Support and Services Department. EASA AD 20200087 also requires modifying the locking safety mechanism, which constitutes terminating action for the repetitive inspections.

FAAs Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAAs bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is issuing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of these same type designs.
AD Requirements This AD requires accomplishing the actions specified in EASA AD 2020

incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD and except as discussed under Differences Between this AD and the EASA AD.
Explanation of Required Compliance Information In the FAAs ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation authority CAA
ADs as the primary source of information for compliance with requirements for corresponding FAA
ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, EASA AD 20200087
is incorporated by reference in this FAA
final rule. This AD, therefore, requires compliance with EASA AD 20200087
in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Using common terms that are the same as the heading of a particular section in EASA
AD 20200087 does not mean that operators need comply only with that section. For example, where the AD
requirement refers to all required actions and compliance times, compliance with this AD requirement is not limited to the section titled Required Actions and Compliance Times in the EASA AD. Service information referenced in EASA AD
20200087 for compliance will be available at https www.regulations.gov by searching for and locating FAA
20210785.
Differences Between This AD and the EASA AD
Where EASA AD 20200087 refers to the effective date of EASA AD 2014
0241E or its effective date, this AD
requires using the effective date of this AD. Where EASA AD 20200087 refers to Group 1 and 2 helicopters, this AD
does not refer to any groups of helicopters. Where the service information referenced in EASA AD
20200087 allows the pilot to perform the requirements of the ASB, this AD
requires the requirements to be performed by a qualified mechanic.
Where the service information referenced in EASA AD 20200087
specifies to submit certain information to the manufacturer, this AD does not include that requirement. Where the service information referenced in EASA
AD 20200087 specifies to discard certain parts, this AD requires removing those parts from service instead. EASA
AD 20200087 requires repeating the inspection before next flight after each application of painting on the LH side

stairway door or its external door handle, whereas this AD does not.
EASA AD 20200087 allows a terminating action for the repetitive inspections, whereas this AD does not.
EASA AD 20200087 requires contacting the Airbus Helicopters Support and Services Department if it is impossible to recondition the locking safety mechanism by moving the door handle, whereas this AD requires, before further flight, accomplishing paragraph 5 of EASA AD 20200087 or accomplishing corrective action using a method approved by the Manager, International Validation Branch, FAA.
The Managers approval letter must specifically refer to this AD.
Justification for Immediate Adoption and Determination of the Effective Date Section 553b3B of the Administrative Procedure Act APA 5
U.S.C. 551 et seq. 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 providing notice and seeking comment prior to issuance.
Further, section 553d of the APA
authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause.
This AD clarifies an exception in AD
20211602 that could affect compliance and the public was previously provided opportunity for comment on the costs of the AD and required actions.
Accordingly, notice and opportunity for prior public comment are unnecessary pursuant to 5 U.S.C.
553b3B. In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553d for making this amendment effective in less than 30
days, for the same reasons the FAA
found good cause to forgo notice and comment.
