Does anyone have additional info/links to info about this tragic accident? What happened to the power levers and where was the captain?

Date: 31 March 1995
Airline: Tarom
Flight No.: 371
Aircraft: Airbus A310-324
Location: Bucharest, Romania
Fatalities: 60:60

The aircraft departed Bucharest-Otopeni runway 08R at 9:08am local time for a flight to Brussels. At 9:11, climbing through 4500ft, the Airbus began to descend again and finally entered a steep dive (80° nose-down) before crashing into a field. While climbing through 2000ft at 189 knots, the crew retracted flaps. At that time the auto throttles (on 'climb' mode) should have reduced power to the pre-determined climb setting on both engines. But the right power lever (no.2 engine) remained in takeoff power setting. It took the no.1 power lever 42 seconds to move to idle power. During these 42 seconds an asymmetric thrust situation developed. The aircraft by then had passed the 'OTR' VOR beacon and the crew had, according to SID procedures, begun a 25° left turn onto a 327° heading for the Strejnic 'STJ' VOR/DME beacon. Due to the thrust asymmetry, the nose-up pitch of 18° decreased to 0°. The aircraft rolled through 170° laterally and finally crashed into an open field and exploded on impact. The accident was likely caused bya lack of crew response to an extreme nose-down attitude. The investigation committee concluded that the Captain was either incapacitated or absent from his seat, because he had not said anything while the critical situation was developing. Just before impact the First Officer expressed his concern about the situation (either the Captain's condition or the aircraft's attitude) and attempted a recovery.

From general recall

Friction on throttle levers was a known problem with this aircraft and had been squawked several times before this flight. DFDR confirmed throttle lever slipping back on one engine as aircraft climbed into low scud (no visible horizon). As power level decreased on slipping throttle for one engine the autothrotle system advanced the throttle on the other engine causing the aircraft to roll over in climb-turn. (deja-vu with B737-300 accident in China a year earlier). The crew was busy with ATC clearances and failed to detect the roll over until the nose dropped. and the ground became visible as they broke out of the scud at 900 ft with 60 degrees of nose down pitch and 350 kts.

Not much on CVR except normal conversation until the last second. I never heard the story about the Captain being absent or incapacitated and I doubt it.

Needless to say it was crew error, because somebody wasn't scanning the instruments, somebody wasn't flying the airplane. It doesn't matter what the Auto Throttles did on their own nor what the selected Auto Pilot did on its own.
