Publications” section of EASA AD 2022-0168.
Unsafe condition
This AD was prompted by reports of multiple multi-function display (MFD) failures during flight. The FAA is issuing this AD to address failure of an MFD and consequent loss of display information during flight. The unsafe condition, if not addressed, could result in the unexpected loss of display of important flight parameters to the pilots, which could result in loss of control of the helicopter.
Affected ADs
None.
