"I want to be the oldest person to scale Everest again to be an inspiration for people around the world", Sherchan had told reporters at his home last month before his expedition. He was later bested by Japanese mountaineer Yuichiro Miura, who was 80 when he summited the world's tallest mountain in 2013.
Eighty-five-year-old mountaineer Min Bahadur Sherchan, who previously held the title for world's oldest climber to top Mount Everest, died Saturday while attempting to reclaim the record, the Associated Press reports.
"He passed away at the base camp today at 5:14 p.m.", said Gyanendra Shrestha, an official with the tourism ministry who is at the 5,380 meters (17,600 feet) camp.
Sherchan first mastered the summit of Everest in 2008 when he was 76 earning him a Guinness World Record as the oldest man to scale such heights.

Sherchan said his goal for making the climb again wasn't exclusively to break Miura's record, however.
He was born in the mountains so never had a problem with altitude or low levels of oxygen.
Mr Sherchan had said he meant to travel to conflict areas to spread a message of peace once he completed the Everest climb.
Sherchan's love of mountaineering began in 1960 when he was assigned by the Nepalese government to be a liaison officer for the Swiss team climbing Mount Dhaulagiri. He was not a professional climber, but had worked as an apple farmer, construction worker and hotel manager in Kathmandu.
May is the best month to climb Everest and there are at least a couple of windows of favorable weather on the summit.
