Try this from AI a couple of years ago when I asked the same question.
Uncommanded Flap Retraction during Take Off.
Situation
An aircraft (320) was dispatched with SFCS No 2 SLAT Channel de-activated iaw MMEL 01-27-51-01 B.
SFCS No 2 FLAP Channel has validated an intermittent high computed airspeed from ADIRU 1. As the aircraft was in Config 1+F, the SFCS No 2 FLAP Channel engaged the FLAP Auto Command to retract the flap. The auto command is available only in Config 1+F with airspeed above 210 kts. SFCS No 2 FLAP Channel was unable to crosscheck the airspeed coming from No 1 ADIRU with the ADIRU 2 airspeed coming from SFCS No 2 SLAT Channel (INOP iaw MMEL above).
The same condition would occur if dispatched with ADR/IR 2 inop, having selected the rotary switch to off.
