The airline must hold open investigation into the accident to regain customer trust amid efforts to overhaul the company to spur growth, analysts say

The London-bound plane, carrying 242 passengers and crew, went down shortly after taking off from the western Indian city of Ahmedabad. Only one person survived.

The deadly accident has raised questions about what possibly went wrong for the Boeing Dreamliner, one of the most modern passenger aircraft in service.

Analysts say pinpointing the reason will need a deep and detailed study, but the manner in which the plane heading for Gatwick Airport hit a building and exploded into a fireball is bound to cast doubts about management of its operations.

“It looks like he [the pilot] had no power available and could not continue his climb. That is a technical issue. It brings up a whole lot of other issues as well about how the airline is being run,” said Mark D Martin, CEO of aviation consultancy Martin Consulting.
