Plain English Summary

3/10 complexity

This airworthiness directive requires operators of SIAI Marchetti F260 series aeroplanes (serial numbers up to and including 735) to inspect the wing main spar web for cracks and to follow SIAI Marchetti Service Bulletin No. 260-B50.

It sets staged initial deadlines based on aircraft hours and mandates repeat inspections every 500 hours until the modification in the Service Bulletin is completed, so operators carry inspection and modification costs and must schedule recurring maintenance.
