Unsafe Condition
Damage to aileron balance and interconnect cables due to electrical arcing between the flap solenoid and the cables, which could cause hazards in flight.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect aileron balance and interconnect cables and flap solenoid for damage from electrical arcing within 50 hours in service. Repair damaged components before further flight except under FAR 21.197. Within 100 hours in service, inspect, repair cables, and alter flap solenoid installation per Piper SB No. 567 or equivalent.
