Were 4 engine piston aircraft like the DC 6 or turboprops like the Brittannia permitted to do 3 engine ferry flights
Three engine ferry flights? Good lord, the Strats and Connies used to do three engine pax flights
Failure rate and precautionary shut downs being prevalent.
Apparently three engine ferries were permitted, maybe depend on country, quote from report into a Super Constellation in Puerto Rico Apr 5, 1990 Elsewhere a flight engineer on Connies said three engine ferries were standard practice to get to an engineering facility..
The captain of the airplane elected to take off on a three engine ferry flight without authorization. During the three engine climb out with the n°3 propeller feathered, the n°2 engine caught fire and he could not extinguish the fire. He attempted to return and during the descent the n°1 engine failed. He then intentionally ditched the airplane in the ocean, and received fatal injuries. The airplane was not recovered from the ocean and no determination of cause could be ascertained.
Probable cause:
Fire of an undetermined origin that resulted in a loss of power in two engines during a three engine ferry flight. Factors related to the accident were: failure of the pilot to obtain the required authorization for the three engine ferry flight, and his operation of the aircraft with known deficiencies.
