Emergency power, or RAT, deployed frequently on Boeing 787s, finds inquiry
When Air India Flight 117’s emergency power system deployed unexpectedly during a landing in Birmingham on October 4, it was part of a pattern affecting dozens of the aircraft – a Boeing 787-8 — worldwide, the aviation regulator has learnt.
As the Boeing Dreamliner jet approached the runway for landing, its emergency power turbine – the RAT, or ram air turbine – unexpectedly folded out of its fuselage when the jet was at 1,600 feet.
