India's civil aviation regulator has completed enhanced safety checks on 24 of Air India's 33 Boeing 787 Dreamliners without finding "any major safety concerns."
"The aircraft and associated maintenance systems were found to be compliant with existing safety standards," India's Directorate General of Civil Aviation (DGCA) said in a statement Tuesday.
The agency undertook the inspections in the wake of the June 12 crash of Air India Flight 171, operated with a Dreamliner, which killed 270 people aboard and on the ground.
The DGCA planned to complete two additional inspections on Tuesday, after the release of its statement, and another one on Wednesday.
Among Air India's six other Dreamliners, four are in maintenance hangars for work and two are currently grounded and out of service in Delhi. The DGCA will conduct safety checks on each of those planes before they return to operation.
Air India Dreamliner turns back after takeoff
On Monday, four days after the Flight 171 crash, an Air India Dreamliner bound for Delhi turned back to Hong Kong shortly after takeoff due to an unspecified technical issue.
Air India has canceled 66 scheduled Dreamliner flights since June 12, the DGCA noted, with 432 having been scheduled. The agency recommended that Air India ensure availability of adequate spare aircraft to mitigate passenger delays while maintenance-related issues continue.
