Boeing failed to rectify faulty equipment after 2009 crash

Boeing, however, did not take any corrective measures to fix the problem, although it did notify other carriers, including Air India Express. According to the report, accessed by Deccan Herald, shortly after the accident on February 25, 2009, the initial investigation results indicated that the left radio altimeter system “passed on an erroneous altitude reading of -8 feet to the automatic throttle control system (autothrottle)”.

The report points out that during the landing approach, the left radio altimeter, which is on the pilot-in-command’s (left-hand) primary flight display, showed an “incorrect height of -8 feet”. The co-pilot’s flight display, by contrast, indicated the correct height as provided by the right radio altimeter.
