Preliminary Report Released by Indonesian Aviation Authorities

Indonesian authorities released a preliminary report regarding their findings into the crash of Lion Air Flight 610.  As mentioned in prior posts, early reports indicated that accident investigators were focusing on the aircraft’s new Maneuvering Characteristics Augmentation System (M.C.A.S.) which is an automated system designed to prevent the aircraft from entering an aerodynamic stall.  The preliminary report confirmed that this was the investigators’ focus, although the report stated that it was still too early to identify a specific cause for the crash.

Update on the Crash of Lion Air Flight 610

Although no official findings have yet to be released, Indonesian aviation authorities are focusing on the aircraft’s automatic system designed to prevent the 737 Max 8 aircraft from entering an aerodynamic stall.  The system, not found on predecessor 737 models, is known as the Maneuvering Characteristics Augmentation System or M.C.A.S.  The system works in conjunction with Angle of Attack sensors located in the fuselage of the aircraft.  These sensors measure the angle of the aircraft in relation to the air that comes across it.  If these sensors indicate that the angle of attack or AOA is too high, they will transmit this information to the M.C.A.S. which will cause the forward edge stabilizers located on the aircraft’s tail to push up thereby forcing the nose of the aircraft downward.  If the M.C.A.S. did in fact engage as a result of faulty information transmitted by the aircraft’s AOA sensors, the pilots would have been confronted with a situation for which they were not trained and would have required them to rapidly engage in a series of steps to take control of the aircraft away from the M.C.A.S.  If they attempted to simply raise the nose of the aircraft by pulling back on the control yoke – which likely would have been the flight crew’s natural reaction – this would have had little effect as the forces exerted by the M.C.A.S. are much greater than the pilot could muster through pulling back on the control yoke.  Instead, the pilots would have had to quickly respond with a number of actions for which they had received no training in order to regain control of the aircraft and disable the M.C.A.S.

NTSB Releases Preliminary Report on the Crash of Liberty Helicopters AS350B2, N350LH

On March 26, 2018, the National Transportation Safety Board released its Preliminary Report in connection with its investigation into the helicopter crash.  The Preliminary Report, a copy of which can be found here, sets forth a brief synopsis of the facts relating to crash based upon preliminary examination of the aircraft wreckage and an interview with the surviving pilot.  The Report contained a discussion of the pilot’s prior flights on the day of the accident, as well as his supposed safety briefings that he gave the passengers prior to the accident flight, including apparently the manner in which the passengers were to extricate themselves in the event of an emergency landing.
