 The International Herald Tribune and Asahi Shimbun reported on June 14 that "Loose bolts and worn brake pads, evidence of poor maintenance, likely played a central role in the elevator accident".In the article it can also be read that "it is the responsibility of the maintenance company to ensure that such bolts are tightly fastened".Schindler pointed out that the maintenance of the elevator was carried out by a non-affiliated maintenance company and that the company does not have an indication of a product design mistake so far.
