Appendix A to AD 2019-16-16 Rotorcraft Flight Manual Supplement (1) Helicopter operation is prohibited if the filter is wet or when visible moisture (rain/snow/ice/water) is present in the inlet or on the filter (inspect filter by hand for wetness). If the filter is wet, remove the filter from service prior to operation. (2) Helicopter flight is prohibited in visible moisture. (3) If the helicopter inadvertently enters precipitation (rain/ snow/ice/water), open bypass doors (if equipped), avoid sudden and rapid power transients, and land as soon as practical. (4) Inlet covers must be installed when the rotorcraft is not in flight to prevent moisture from collecting in the inlet or on the filter. (5) Inspect inlet and filter for visible moisture accumulation prior to flight. If moisture is present, helicopter operation is prohibited.
