To prevent rapid cabin decompression and passenger injury due to window breakage caused by ice shed from the propellers, accomplish the following:
(a) Prior to further flight unless accomplished in accordance with AD 90-12-14, modify the passenger seat adjacent to the cabin window at Station 181 on the right side of the cabin on those airplanes whose propellers turn counterclockwise looking forward, or on the left side of the cabin on those airplanes whose propellers turn clockwise looking forward, by accomplishing one of the following actions:
(1) Fabricate a placard using letters at least one inch in height on a contrasting background to read: "DO NOT OCCUPY THIS SEAT AT ANY TIME" and install this placard on the passenger seat closest to the cabin window at Station 181 of the passenger cabin in clear view of the occupants, or
(2) Remove the passenger seat closest to the cabin window at Station 181 of the passenger cabin.
(b) Within the next 30 calendar days after the effective date of this AD, unless accomplished in accordance with AD 90-12-14, reinforce the applicable cabin window located at Station 181 in the passenger cabin in accordance with either paragraph (b)(1) or (b)(2) of this AD. The restrictions required by paragraph (a) of this AD are no longer applicable when this modification has been accomplished.

(c) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished.
