A scandal over improper maintenance work at jet-engine maker IHI Corp. deepened as the company said it has found over 7,000 cases of flawed engine inspections in the process of making engine parts during the two years through January.
The latest findings, which also affect parts supplied to Self-Defense Forces aircraft, raised the tally of improper inspections by the Tokyo-based company to over 13,000. IHI said Monday it has found no safety problems due to the improper checks.
IHI, a supplier of engines to Boeing Co. and Airbus S.A.S., is among a slew of Japanese manufacturers recently embroiled in scandals over improper quality controls on their products, including Nissan Motor Co. and Kobe Steel Ltd.
