Hi all....last week I had to (at great expense to management
) replace the ring gear on my Raven 2 after just 250 hours.
Sitting alongside were two other Raven 2s undergoing the same surgery.
The engineers put the high failure rate down to an incorrect starting procedure used by most pilots.....basically beginning to feed in mixture BEFORE releasing the starter button.
I am a little sceptical and would be interested in feedback regarding:
- experience with with incidence ring gear failure around the traps and if it is higher on Raven 2s than other machines,
- technical thoughts on the explanation offered.
Thanks!
