Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Jetstream Model 4101 airplanes. This proposal would require an inspection to verify the proper position of ``door open'' placards on the inside of the main entrance door, and replacement with new placards appropriately positioned, if necessary. This proposal is prompted by a report that the ``door open'' placards on the inside of the main entrance door, as currently installed, may not be visible to passengers or flightcrew when the door handle is in the open position. The actions specified by the proposed AD are intended to ensure that certain placards on the inside of the main entrance door are clearly visible and perform their intended function in the event of an emergency evacuation.
