Federal Register / Vol. 86, No. 119 / Thursday, June 24, 2021 / Rules and Regulations this final rule. The FAA has considered the comment received. The Air Line Pilots Association, International ALPA
indicated its support for the NPRM.

Federal Register on February 22, 2021
86 FR 10493. The NPRM was prompted by a new, water-resistant ICP
developed by the manufacturer to address the identified unsafe condition.
The NPRM proposed to continue to require revising the existing AFM to define a liquid-prohibited zone on the flight deck and provide procedures following liquid spillage on the center pedestal. The NPRM also proposed to continue to require installing a removable ICP cover on the flight deck and further revising the AFM to include instructions for ICP cover use, as specified in EASA AD 20200203. The NPRM also proposed to require installing a new, water-resistant ICP, which would allow removing the ICP
protective cover and the AFM revisions, as specified in EASA AD 20200203.
The FAA is issuing this AD to address the potential for dual-engine in-flight shutdown IFSD, possibly resulting in a forced landing with consequent damage to the airplane and injury to occupants.
See the MCAI for additional background information.

Change to the Costs of Compliance Section In the NPRM, the FAA did not provide a parts cost estimate for the new actions, and it was noted that the FAA
had received no definitive data regarding cost estimates for those parts.
Since publication of the NPRM, the FAA has obtained a parts cost estimate from the manufacturer, and has updated the Costs of Compliance section of this final rule accordingly.
Conclusion The FAA reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM.

cover use. EASA AD 20200203 also describes procedures for installing a new, water-resistant ICP; removing the ICP protective cover; and removing the AFM revisions.

The FAA has received no definitive data regarding cost estimates for these parts.

The FAA has received no definitive data on which to base the cost estimates for the on-condition actions specified in this AD.
According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. The FAA does not control warranty coverage for affected operators.
As a result, the FAA has included all known costs in the cost estimate.
