Applies to Fairchild Hiller F-27 and FH-227 aircraft certificated in all categories, incorporating a stewardess jump seat mounted on the rear lavatory wall facing aft, and where the head of a seated crew member would be within striking radius of the retracted rear passenger stairs.

"DO NOT OCCUPY STEWARDESS JUMP SEAT."

(c) Upon accomplishment of a modification to the stewardess seat station to show compliance with CAR 4b.358, approved by the Chief, Engineering and Manufacturing Branch, FAA Eastern Region, the placard may be removed.
