Does not explain the petals extended after the second landing, nor flying the GA with REV open.
Looks like some darn mechanical failure that was really not supposed to happen in a post-Lauda 767 world. (cometh forward, the Master of the combustion chamber?)
You called?
Not too familiar with the T/R system on Airbus. Is it possible to advance the thrust lever (damn, almost wrote throttle lever
) off idle with the reverse lever extended? On Boeings, there is a mechanical interlock that locks the forward lever to idle if the reverse lever isn't stowed - don't know about the A320. If it is possible to advance the forward lever with the reverse lever not stowed (or there was a failure of the interlock), it could explain what happened (depending on the specifics of the A320 auto-restow system). If they had to stow the reverse lever before selecting TOGA, then there would need to have been some sort of mechanical fault that prevented the reverser from completely stowing.
While Boeing specifically states that performing a go-around after reverser deployment is not recommended, it is a design requirement that the reverser will successfully stow.
