the starter valve stuck open, in the book it says maintenance action due.
whats is this particular maintenance action?
If its stuck open then a (usually) 3/8" square drive is needed to go through the appropriate access door and shut it once the donk is self sustaining....
A stuck open start valve all the way to idle would probably result in a start valve and a starter moter replacement.
I have on larger Buses >320... The starter valve /motor open to idle speed, and the gears came out of the starter moter and embedded themselves in the adjacent IDG requiring replacement of both. ( I wish I could find pics to display)
