Does this procedure applies for specific MSNs or is it for all MSNs? I just checked my FCOM (for A319s up to 23XX and A320s up to 52XX) and apparently it has the "old" procedure of recycling the gear (though it doesn't say how many times, so I'd assume it's just one), waiting for uplock and doors closed before moving the lever down. If unsuccessful, it immediately refers you to gravity gear extension after the 120s "dwell time"
I read the AD and it's specifically says "up to 5 times" as Mongo said and then if unsuccessful, wait 120s and do the gravity extension.
Is the difference because we may have different PN on the whole system which doesn't require the 5 attempts method or is it just that my company has outdated manuals/procedures?
Thanks for the link to the AD, Vilas
