Was performing annual inspection on a Cessna twin and discovered a cracked cylinder. Research revealed related ADs for this model of Cessna; however this plane in question is outside the serial range of the AD. I believe the serial range should be extended to include these later serial numbers as it is a serious issue and others could be affected. Reference Airworthiness Directive 2016-16-12.
