It hasn't flown since 2004 so whether it could be considered airworthy is subjective, although it is supposedly 'being worked on'. Photos show it with and without JT8Ds over the years, and overall intact.
Not sure why it would be worked on, because the type certificate for the Caravelle has been retired by EADS (I know, it's Africa...) and owner Waltair lost its operating licence in 2005.
