In 1993 Tashi led the 40th Anniversary Everest Expedition to mark the 40th anniversary of the first successful expedition of his grandfather, Tenzing Norgay. While his team was successful in getting two members to the summit on 10 May, Tashi's uncle and climbing partner, Lobsang Tshering, fell to his death on the descent from the summit. Tashi himself missed the summit as well by just 400 metres, having to turn back with snow blindness.
