Oh, and obviously, while you are investigating this issue, DO NOT let yourself get into the same situation as before. So make sure the aircraft is fully settled in the approach configuration (slats extended, flaps extended, power properly set for flight in that envelope) before you descend below the altitude from which you can safely recover from a wing drop. If at all possible, try to avoid having to make turns once below that altitude, so try to fly a long final, traffic permitting. An ILS-like profile, where you are in the landing configuration and at a reasonable approach speed, 6 nm/2000' out, would be ideal.
