A Boeing Co 737 cargo plane operated by a Qantas Airways Ltd subsidiary suddenly depressurised during a flight last year after a misplaced insulation blanket clogged up the main outflow valve, Australia’s air-safety investigator said.
Cold air rushed into the cockpit and the two-person crew suffered pain in their ears when the jet lost cabin pressure descending through 8,000 feet (2,400 meters), the Australian Transport Safety Bureau said in its report on the July 6 incident. The Express Freighters Australia flight was heading to Melbourne from Perth and landed safely.
