Acha ushamba huwezi kuuziwa ndege mpya bila certification ya aviation authoritiesUmejijibu ndege ambayo 'sio airworthy', so the issue is not about whether the airplane is new or not but Rather if it's air worthy ...unaweza pata ndege mpya fresh from jikoni na ikose kua air worthy Mpaka ikue cleared for test. So my question to you is ... ile ndege ya mama before they inqured for a new one, was it airworthy or not!?
