A Naval sailor was killed on Saturday when a Chetak helicopter was involved in a "ground accident" at a naval air station in Kochi, the Indian Navy said.
The Navy ordered a probe into the matter.
The incident occurred at INS Garuda of the Southern Naval Command during routine maintenance taxi checks, Defence sources said.
While initially it was believed to be a crash, officials later clarified it was a mechanical failure.
"A Chetak helicopter met with a ground accident today during maintenance taxi checks at INS Garuda, Kochi, resulting in the unfortunate loss of life of one ground crew," it said.
The deceased was a Leading Air Mechanic (LAM).
"Adm R Hari Kumar #CNS (chief of naval staff) & all personnel of #IndianNavy mourn the loss of life & pay tribute to Yogendra Singh, LAM who lost his life in the unfortunate accident at Kochi and extend heartfelt condolences to the bereaved family," the Navy Spokesperson said on X.
