Departed runway with flaps a 50% achieved 85 kts on climb and retracted flaps. Indicator showed 0 degree flaps. Checking visually flaps were still at 50% reset 50% flaps and tried retract no success. Dialed 100% flaps and flaps went to to full flaps. Retracted to 50%, flaps followed. Again lowered to 100% flaps went to 100%, Retracted to 0 degrees and flaps followed to 0 degrees.

No reason - since then flaps seemed to work.

any thoughts ?


Were you transmitting when you first selected 0% flaps on the climbout?
