Boeing to issue safety warning to pilots for 737 Max jets
Nov 08 2018
The notice refers to the "angle of attack", which is the angle of the wing relative to oncoming air stream, a measure that indicates if a plane is likely to stall.
Lion Air's first two attempts to address the airspeed indicator problem didn't work and for the Boeing 737 MAX 8 plane's second to last flight, the angle of attack sensors were replaced, he said.
Erratic speed and altitude on the plane's previous flight, from Denpasar on Bali to Jakarta, were reported and "when we opened the black box, yes indeed the technical problem was the airspeed or the speed of the plane", National Transportation Safety Committee chairman Soerjanto Tjahjono told a news conference.
Tjahjono said Flight 610 was intact with its engines running when it slammed into the sea 13 minutes after takeoff. CNN said Indonesian officials are working with Boeing and safety experts to further investigate the airspeed indicator issue.
Family members and friends have farewelled loved ones who died in the Lion Air planecrash in an emotional memorial service at the crash site in Indonesia.
The crashed aircraft was undertaking its JT610 flight from Jakarta to Pangkal Pinang, on the island of Bangka off Sumatra, on October 29. Indonesian officials said they have downloaded the data from a black box recorder for Lion Air flight 610 which crashed into Java sea last week while at least 105 body bags containing parts of passengers have been handed to the national police hospital in Jakarta for identification.
WestJet also has 9 of the 737 MAX jets in its fleet, but the airline did not immediately respond to a query about the Boeing bulletin from CBC News. He maintained that the agency is now studying it based on the pieces of evidence they managed to recover so far that includes the plane's flight data recorder (FDR).
The AD followed Boeing's issuing of an operations manual bulletin (OMB), asking 737 MAX operators to remind pilots of how to handle "erroneous" information from the aircraft's angle of attack sensors.
Aerospace and defense giant Boeing is planning to issue a safety warning to people flying its 737 Max jet, Bloomberg reported on Tuesday.
"The draft of what will be conveyed by Boeing this morning has been presented to us", air accident investigator Nurcahyo Utomo said.
Analysts say finding the cockpit voice recorder is imperative if investigators are to determine whether the crash has implications for other airlines collectively operating thousands of Boeing 737 flights around the world each day.
The investigation is now focused on flight data from one of the black boxes, found last week.
Boeing says that the 737 MAX is the fastest-selling airplane in the company's history, with over 4,700 orders to date. The flight was then grounded for 12 hours.
Indonesia's rescue agency said Sunday that wreckage spotted by divers had turned out to be only pieces of skin of the Boeing Co. jet rather than the main fuselage.
"There was some unusual noise coming from the engine and I could hear it because I was sitting in the window seat of row 22 near the wings", he said, adding that the plane's landing in Jakarta was not smooth either and bounced slightly as the tires touched the runway.
PREMIUM Indonesia has been shocked by the plane crash involving Lion Air flight JT610.
