I am trying to figure out how to determine what Service Intruction has been released to supercede an old one at Lycoming. Specifically I was trying to find Service Instruction 1129A (Accessory Drive Belt Tension) and it is not listed in the Service Instruction library (http://www.lycoming.textron.com/support/publications/service-instructions/index.html). There is not another one with a similar name, so how does one find a newer one that replaced this one?
