NEW DELHI, June 24 (Reuters) - India's aviation

regulator said on Tuesday it had found multiple instances of

aircraft defects re-appearing "many times" at Mumbai and Delhi

airports, two of the country's busiest.

The repeated instances of defects indicated "ineffective

monitoring and inadequate rectification action," the Directorate

General of Civil Aviation said.

In the wake of the deadly Air India crash this month, the

regulator last week said it had initiated a special audit of the

Indian aviation ecosystem to strengthen safety.
