Narrative:Air Inter flight 696 departed Lyon for a night time flight to Clermont-Ferrand. It was raining in the area of Clermont-Ferrand, the visibility was around 5 miles with a low 4/8 ceiling at 2300 feet and an overcast at 8000 feet. Near Clermont-Ferrand, the crew had to fly a holding pattern before being cleared to descend to 3600 feet. Then the airplane's radio compass shifted 180-degrees, probably because electrical discharges in the rainfall blocked the signals of the Clermont-Ferrand NDB. The crew initiated their descent too early and the Viscount collided with a mountain (Pic du Picon) at 1000 feet, 44km east of the airport.
