Strange engine noise
737-300 CFM engines
Spin engine inspect blades on walk round. Hear sound similar to ball in roulette wheel as fan slows to a stop. Didn't accept suggestion to ferry to major service depot. Possibly should have.
U/S
Head sheared from tie bolt and floating around engine internals. Light to moderate blade fir trees' damage.
(p.s. This the style you are looking for?)
