EASA 2020-0069

Supersedes but retains the requirements of EASA AD 2019-0001, which mandated an inspection to check the correct operation of the sliding door locking mechanism by measuring the load required to open it. Updated AD addresses a design deficiency with a modification (MOD 075105) that improves tightening of the sliding door latch, accomplishment of which provides terminating action for the repetitive visual inspections. Prompted by occurrences of in-flight detachment of the left-hand side cabin sliding doors due to degradation of the sliding door locking mechanism. In some of these cases, impact damage was observed on main rotor blades.
