The first attempt to land at Paris-Orly at night, ILS, monitored by GCA, failed. The crew decided to try a second time with GCA guidance. Full power was applied when the crew were not able to see the runway. The aircraft continued to descend however and impacted the ground in a right bank. The right hand wing separated and the main fuselage broke up into four main parts. PROBABLE CAUSE: “Stalling as a result of delayed application of power with a heavy aircraft in final approach configuration and inadequate control of heading, airspeed and altitude after the visual break-through. The following contributing factors are noteworthy: deteriorating in weather conditions in the immediate vicinity of the runway threshold; absence of radio altimeter; faulty application of landing techniques by both ground and flight personnel.”
