## ERA Helicopters LLC What change to the AD action is requested? 

### "Comment for NPRM 2016-4278 Operational checks of# 

## 1 and #2 hydraulic systems. 

## I am against the addition ofan AD for these hydraulic system checks as the checks already exist in our maintenance program. Due to the release ofBT139-269 and EASA AD20 11-0207, we currently have a 600 hour/12 month inspection/operational check that covers all ofthe items in this new AD. The new AD would not change any ofour maintenance procedures, only require additional paper work for the same result. Thank you." Why is the change requested or how is itjustified? '·
