Détails:
After the plane arrived at La Aurora with one engine shut down and one of the electrical generators malfunctioning, the crew decided to ferry the aircraft to Honduras for repairs. The passengers deplaned and the Electra took off for a three-engined ferry flight.
Shortly after take off, the pilot reported a total loss of hydraulic pressure and difficulty to control the plane. The Electra began to return to La Aurora, but the plane lost altitude until it crashed into some houses 1 mile west of the airport.

Probable Cause:

PROBABLE CAUSE: A second electrical generator was damaged during the take off roll, causing a lack of power to keep the hydraulic pressure above minimums. It was also concluded that the flying controls were mistrimmed.
