Détails:
Eastern Air Lines flight 704 took off from runway 27R at Miami International Airport at 16:21 hours.
At about 150 feet above the runway and about the time the undercarriage was retracted the captain noticed fluctuations of the no. 3 engine tachometer. The rpm momentarily dropped from 2600 to 2300 rpm.
The engine began losing power and the captain ordered the engine to be shut down. The flight engineer accomplished these procedures. He did not use the emergency firewall shutoff because no fire was indicated.
However, Miami tower personnel noticed the aircraft trailing smoke and flames from the no. 3 engine nacelle area. The local controller informed the flight and cleared it to land on any runway.
The flight engineer then fired two fire extinguishing bottles of the no. 3 engine. Fire however continued to burn until the aircraft landed on the runway.
After touchdown braking became ineffective and the no. 4 engine stopped. Also, the nose wheel steering failed. The aircraft overran the runway, upon which the right hand main gear collapsed. All occupants evacuated and the fire was extinguished by fire services in about 30 minutes.

Probable Cause:

Probable Cause: "The Board determines that the probable cause of this accident was an uncontrollable fire ignited in zone 3-A by a burning breather discharge which was ignited by and combined with an abnormal exhaust flame during engine failure."
