The rest of the problem space is obvious.
To me, this is far more interesting:
"Examination of the emergency float system revealed that the three floats installed on the left landing gear skid appeared to be more inflated than the floats on the right landing gear skid. The emergency floats' left pressurized gas cylinder gauge indicated about 0 psi, while the right pressurized gas cylinder gauge indicated about 4,000 psi."
