c Applicability This AD applies to all Airbus Helicopters Model AS355NP helicopters, certificated in any category.
d Subject Joint Aircraft Service Component JASC
Code: 6700, Rotorcraft Flight Control.
e Unsafe Condition This AD was prompted by a report of mechanical deformation found on the protective cover also referred to as switch guard of the SHEAR control pushbutton installed on a co-pilot collective stick of a Model EC225LP helicopter, caused by incorrect handling; due to having an identical design switch guard installed on the pilot collective stick, Model AS355NP
helicopters are also affected. The FAA is issuing this AD to address mechanical deformation on the protective cover of the SHEAR control pushbutton installed on the pilot collective stick. The unsafe condition, if not addressed, could result in unintended shearing of the hoist cable, possibly resulting in injury to hoisted persons.

Airworthiness Directives; Various Helicopters Federal Aviation Administration FAA, DOT.
ACTION: Final rule; request for comments.
AGENCY:

The FAA is adopting a new airworthiness directive AD for all helicopters equipped with a radio also known as radar altimeter. This AD was prompted by a determination that radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.73.98
GHz frequency band 5G C-Band. This AD requires revising the limitations section of the existing rotorcraft flight manual RFM for your helicopter to incorporate limitations prohibiting certain operations requiring radio altimeter data when in the presence of 5G C-Band interference in areas as identified by Notices to Air Missions NOTAMs. The FAA is issuing this AD
to address the unsafe condition on these products.
DATES: This AD is effective December 9, 2021.
The FAA must receive comments on this AD by January 24, 2022.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:
Federal eRulemaking Portal: Go to https www.regulations.gov. Follow the instructions for submitting comments.
Fax: 202 4932251.
