As you watch the video identify hazards relating to the failed aircraft system. In your
initial post use the risk assessment format in Chapter 11 pgs. 141-142 of the
textbook to explain:
Hazard risk, Item 1: Loss of all primary flight control surfaces
. The hydraulic system
controls the ailerons, flaps, rudder, and elevator (Nature TV, 2019). The hazard
mode is described as malfunctions of the hydraulic system or loss of hydraulic
power, causing the loss of control of the primary flight control surfaces. This
condition is hazardous at any time of a flight operation because the changes in
primary flight controls can affect the lift and drag of the aircraft (Federal Aviation
Administration [FAA], 2016). Although this hazard does not pose a discernible effect
on other systems, the significant result of this hazardous condition could lead to a
total loss of control of the aircraft and the occurrence of a catastrophic accident,
which could cause fatal injuries.
Risk assessment, Item 1: 1D.
This hazard is categorized as catastrophic because of
its potential loss of human life. The probability of occurrence is considered remote as
three hydraulic systems were isolated and had its distinct function. However, failure
of all three hydraulic systems at the same moment could happen when there is
explosive damage where the debris damaged the entire hydraulic systems, which is
one of the contributing factors to the United Airlines flight 232 (Nature TV, 2019).
