Summary
Requires amending the rotorcraft flight manual to incorporate an air conditioning system altitude correction procedure and replacement of air conditioning condenser outlet grids with covers. Prompted by an investigation that found the grids affect the static ports of pitot-static systems 1 and 2. If not corrected, this condition could lead to airspeed and altitude indication errors.
