A Douglas DC-3A cargo plane experienced a catastrophic failure of its second engine shortly after takeoff from San Juan-Luis Mu¤oz Mar¡n International Airport in Puerto Rico. The flight crew executed a right downwind leg to return to runway 10 for landing, but lost control, resulting in a right vertical bank and subsequent crash into Laguna San Jos‚. The failure was attributed to inadequate airspeed, improper pilot command, improper aircraft handling, failure of contributing factors such as terrain and equipment, and engine assembly issues.A Douglas DC-3A cargo plane experienced a catastrophic failure of its second engine shortly after takeoff from San Juan-Luis Mu¤oz Mar¡n International Airport in Puerto Rico.
