Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede airworthiness directive (AD) 2002-13- 11 for Eurocopter France (now Airbus Helicopters) Model EC120B helicopters. AD 2002-13-11 currently requires installing front and side covers on the cabin floor to protect the yaw control at both the pilot and co-pilot stations. Since we issued AD 2002-13-11, we have determined that the required actions should apply only to the cabin's right-hand pilot station. This proposed AD would retain the requirements of AD 2002-13-11 but for only the pilot station. These proposed actions are intended to prevent an object from sliding between the canopy and the cabin floor, loss of yaw control, and subsequent loss of helicopter control.
