Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A321 series airplanes. This proposed AD would require repetitive measurements for correct control rod gap of the hold-open mechanism of all emergency doors, and corrective actions if necessary. This proposed AD would also require replacing the control rods with new, improved control rods, which would terminate the repetitive measurements. This proposed AD is prompted by a report that an operator found it impossible to lock emergency doors 2 and 3 in the open position. We are proposing this AD to prevent failure of the emergency doors to lock in the open position, which could interfere with passenger evacuation during an emergency.
