    P300 - SB505-27-0030 - PTA Position Sensor Filter Installation

    P300 - SB505-27-0030 - PTA Position Sensor Filter Installation

    This new SB applies to the whole fleet (50500005 thru 50500671) and helps reduce false CAS PTRIM NML FAIL or CAS PTRIM BKP FAIL messages.

    "To include a capacitor (22uF) to implement a passive filter on the wiper of the PTA potentiometer that indicates the Pitch Trim Position to the FCE."

    When: This Service Bulletin can be accomplished at any time, at the operator’s discretion.
    Coverage: The SB kit will be provided at no charge on attrition.
