2/10 complexity

This AD requires all owners/operators of Cessna 500 series aeroplanes to carry out the work specified in Allied Signal Service Bulletin 103576-21-4056 because cracked valve poppets from a production batch could cause outflow valve failure and rapid decompression.

Work must be done within 200 flight hours from 25 April 1996 or by 31 July 1996, whichever comes first; operators pay for parts, labour and any scheduling impacts.
