The NTSB's narrative final · quoted from the NTSB record
The captain reported that the crew leveled at flight level 370 and received an elevator aileron computer (ELAC) number two pitch fault message. The message cleared itself. A few minutes later they received servo fault message. The 'pitch jumped +/- 100 feet.' The crew descended to flight level 350. During the level off they received an ELAC number one pitch fault message. The crew declared an emergency and landed uneventfully. The aircraft maintenance log revealed a similar occurrence on the previous flight. Investigation revealed an intermittent fault in the elevator servo controller electrovalve coil and a defective diode in the electronic module for one of the stabilizer actuators. The defective diode produced an intermittent loss of electrical motor power during transient, closed loop control of the actuator.
