             Requirement: 1. Install Ice Detector System in accordance with the requirements of MU-2 Service Bulletin No 080/30-003A or No 217A as applicable.

             2. Until Compliance with Requirement 1, a placard is to be installed in clear view of the pilot stating:

             "FLIGHT INTO KNOWN OR FORECAST ICING CONDITIONS IS PROHIBITED" and

            Insert a "P" amendment to the Limitations Section of the Flight Manual. This amendment is available from District Airworthiness Offices.
            Note: The placard is only required until the modification has been incorporated.

 Compliance: 1. Prior to 31 December 1995.

            2. Prior compliance with the initial issue of this AD satisfies Requirement 2.

            Background:  Failure to detect ice build-up on the aircraft by the pilot may result in failure to use or the improper use of the anti-ice/de-ice equipment. This could result in loss of control of the aircraft. The Directive was issued to prevent loss of control of the aircraft as a result of undetected ice accretion.

            This amendment requires installation of an ice detector system as terminating action.
