Masiero was promoted to tenente from sottotentente on 17 January 1918. He would go on to make six more victory claims during the first six months of 1918, to no avail. On 29 March 1918, he left 78a Squadriglia for posting to 3a Sezione SVA to fly the new Ansaldo SVAs. A review committee meeting immediately postwar disallowed at least six previously confirmed victories, leaving Masiero's tally at five confirmed.
