Pilots take aim at instructions for Boeing 737 MAX

Bangkok Desk, Apr 4 (efe-epa).- Some pilots inside and outside the U.S. are expressing concern that crews should have been provided more-detailed instructions about disabling a suspect flight-control system after the first fatal crash of a Boeing Co. 737 MAX airliner in Indonesia, Dow Jones Newswires reported in an article provided to Efe on Thursday.
Preliminary findings from the second crash, which occurred last month in Ethiopia, are expected to stoke criticism from pilots that Boeing and U.S. regulators fell short in highlighting steps crews are supposed to take before turning off a stall-control feature implicated in both crashes.
Ethiopia’s transport ministry, which is leading the probe in that country, is expected to release its interim report on Thursday.
The report is expected to say that the pilots of Ethiopian Airlines Flight 302 initially took a primary emergency step and shut off electric power to the stall-control feature – called MCAS – that was automatically pushing down the jet’s nose, according to people familiar with the probe. When the pilots failed to regain control of the aircraft, these people said, the crew reconnected power and MCAS kicked in again, eventually overpowering pilot efforts to pull out of the fatal dive.
As the pilots of that plane were grappling with the stall-prevention system, the plane plummeted some 5,000 feet in 20 seconds and hit the ground at more than 310 miles an hour, according to another person familiar with the investigation. The cockpit voice recorder retrieved from the wreckage caught at least one pilot calling out “Mayday” before impact, according to the person. But no such radio transmission was received by controllers at the Addis Ababa airport tower, indicating chaos in the
