Compliance is required within the next 25 hours' time in service after the effective date of this AD, unless already accomplished.

To prevent loss of aileron control due to interference with the wing flap control system, modify the wing flap control system, re-rig the wing flap control system, and check for freedom from interference between the wing flap control system and aileron control system in accordance with Socata Service No. 111 GR. 27-11, dated April 1974, or an FAA-approved equivalent.
