The AMT kit is discontinued at HLJ, but this is what they have to say about it:
" A reissue of the AMT 1/48 kit of Airwolf. Includes a complete interior, optional position cannon and missile-launcher armament and retractable landing gear - because we all know a helicopter can't go supersonic without retractable landing gear! Parts are also included that will allow you to build a stock Bell 222, although these are not called out on the instruction sheet and no decals are included."
