KATHMANDU, Nepal — An Indian climber has died while being helped down Mount Everest, just a couple of days after Dutch and Australian climbers died near the peak. Two other Indian climbers are missing, and experts say some of the accidents may have been avoidable.

Poor planning and overcrowding on the world’s tallest peak may have led to bottlenecks that kept people delayed at the highest reaches while waiting for the path to clear lower down, Ang Tshering of the Nepal Mountaineering Association said Monday.

‘‘This was a man-made disaster that may have been minimized with better management of the teams,’’ he said. ‘‘The last two disasters on Everest were caused by nature, but not this one.’’

Many had hoped this year’s climbing season would bring success and restore confidence in the route, after deadly disasters canceled climbing the previous two years.

But as hundreds of eager climbers, joined by Sherpa guides and expedition experts, scrambled to take advantage of good weather to ascend, reports of tragedy began trickling down the mountain.
