There are more than 1,100 of the jets in service today. Air India flies nearly three dozen of them.
It could take months or years to determine the cause of Air India’s crash on Thursday, but the type of plane involved in the episode, a Boeing 787 Dreamliner, has been under scrutiny for years.
Until Thursday, the Dreamliner had never been in a fatal crash, according to a review of accident data maintained by Cirium, an aviation data firm. In a statement, Boeing said that it was aware of the crash on the Air India flight and was “working to gather more information.” Plane crashes are typically caused by multiple factors that can include things like bird strikes, pilot error, manufacturing defects and inadequate maintenance.
The first Dreamliner was delivered in 2011 to All Nippon Airways, Japan’s largest airline. There are more than 1,100 in service today. Air India flies nearly three dozen of the large jets that are typically used for international flights, according to Cirium. The plane involved in the crash, a 787-8, was built in 2013.
But Dreamliner deliveries were paused for more than a year until the summer of 2022, when the Federal Aviation Administration approved a Boeing plan to address quality concerns that included filling paper-thin gaps in the plane’s body and replacing certain titanium parts that were made with the wrong material. None of those problems had an immediate impact on the safety of Dreamliners, Boeing said at the time.
Last year, the F.A.A. said it was also investigating claims by a Boeing engineer that parts of the fuselage, or body, of the Dreamliner were improperly fastened together, which the whistle-blower said could cause premature damage to the plane over years of use.
Boeing disputed that, including at a briefing last year for reporters at the factory in North Charleston, S.C. where the Dreamliner is assembled. Two top Boeing engineers said at the time the company had found no evidence to support the whistle-blower’s concerns after conducting exhaustive tests, inspections and analyses of the plane during its development and in recent years.
