Airworthiness Directives; Raytheon Aircraft Company Models E55, E55A, A56TC, 58, 58A, 58P, 58PA, 58TC, and 58TCA Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Models E55, E55A, A56TC, 58, 58A, 58P, 58PA, 58TC, and 58TCA airplanes. This AD requires you to inspect the Instrument Subpanel electroluminescent panel retaining screw for proper length and the rotating beacon circuit breaker switch (or any other switch in the same location) for damage and replace any screw or circuit breaker switch as necessary. This AD is the result of a report that an improper length electroluminescent panel retaining screw damaged the rotating beacon circuit breaker switch, which resulted in damaged wiring. The actions specified by this AD are intended to prevent damage to the rotating beacon circuit breaker switch or any other switch in the same location because of an incorrect length electroluminescent panel retaining screw. This condition could result in failure of the circuit breaker and lead to smoke and/or fire in the cockpit.
