T Shirt,
The offending prop mentioned before was on a Mercer Airlines DC-6, the
only DC-6 fitted with Curtis-Electric propellers, and the outcome was not a pretty picture.
Double engine failures (on one side) in four engine types can also be...crew induced.
SV 747SP departing JED (mid-1980's) had an uncontained failure of number two, which thru bits into number one...and the wing etc.
Number one, altho producing full rated thrust, had an engine fire indication, and the Flight Engineer, acting on his own (mouth closed), pulled the number one fire pull handle.
800agl, at max weight, on two engines. A nasty picture.
Knew the Captain involved, and if it was not for his skill, the aeroplane would have been spread all over the beach, by the creek.
Airmanship
counts.
PS: The offending F/E had his exit visa and was on the way out two days later. Lucky (for him) he wasn't arrested.
