Abstract
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires installing new fire handle shutoff system wiring. This AD was prompted by a possible latent failure in the fire handle shutoff relay circuit due to a lack of separation between engine wires. We are issuing this AD to minimize the possibility of a multiple engine shutdown due to single fire handle activation.
