AI Tangible Harm Level Notes

Notes about the AI tangible harm level assessment
 

It is unclear whether the MCAS system relied on machine learning or other contemporary AI methods instead of sophisticated rules.

Special Interest Intangible Harm

An assessment of whether a special interest intangible harm occurred. This assessment does not consider the context of the intangible harm, if an AI was involved, or if there is characterizable class or subgroup of harmed entities. It is also not assessing if an intangible harm occurred. It is only asking if a special interest intangible harm occurred.

Ethiopian Airlines flight ET302 from Addis Ababa-Bole Airport (ADD/HAAB), Ethiopia to Nairobi-Jomo Kenyatta International Airport (NBO/HKJK), Kenya, a Boeing 737 MAX 8 registration ET-AVJ MSN 62450/7243, crashed about 6 minutes after takeoff from ADD near Bishoftu, Ethiopia, 8°52′37″N 39°15′04″E. There were no survivors among the 157 occupants. Accident investigation found that the causes were similar to those involved in the accident of Lion Air flight JT610 on 29-10-2018. Quoting from the official investigation report: [QUOTE 3.2Probable cause of the accident Repetitive and uncommanded airplane-nose-down inputs from the MCAS due to erroneous AOA input, and its unrecoverable activation system which made the airplane dive with the rate of -33,000 ft/min close to the ground was the most probable cause of the accident. [p. 255] [UNQUOTE [QUOTE The data from the flight data recorders, as summarized in reports of the ET 302 accident and the Lion Air Flight 610 accident, indicated that if a single erroneously high AOA sensor input is received by the flight control system, MCAS can command repeated Airplane nose-down trim of the horizontal stabilizer. This unsafe condition, if not addressed, could cause the flight crew to have difficulty controlling the Airplane , and lead to excessive Airplane nose-down attitude, significant altitude loss, and impact with terrain [p. 257] [UNQUOTE [QUOTE Safety Issue Summary On the previous Lion Air flight and the Lion Air and Ethiopian Airlines accident flights, the DFDR recorded higher AOA sensor data on the left side than on the right (about 20° higher in the previous Lion Air flight and the Lion Air accident flight and about 59° higher on the Ethiopian Airlines accident flight). As previously stated, the MCAS becomes active when the Airplane ’s AOA exceeds a certain threshold. Thus, these erroneous AOA data inputs resulted in the MCAS activating on the accident flights and providing the automatic AND stabilizer trim inputs. The erroneous high AOA sensor input that caused the MCAS activation also caused several other alerts and indications for the flight crews. The stick shaker was activated on both accident flights and the previous Lion Air flight. In addition, IAS DISAGREE and ALT DISAGREE alerts occurred on all three flights. Also, the Ethiopian Airlines flight crew received a Master Caution alert. Further, after the flaps were fully retracted, the unintended AND stabilizer inputs required the pilots to apply additional force to the columns to maintain the Airplane’s climb attitude. [p. 266] [UNQUOTE]
