Round about 1963 a Victa Airtourer of the Royal Aero Club of NSW, pupil and instructor on board, had elevator jam in flight. Instructor found he could get enough pitch authority to slightly raise or lower the nose by delicate power changes and by cautious adjustment with the trim lever.
Then he set up for a long shallow approach back into Bankstown, landing successfully without further incident.
Incidentally, his initials were RR, he had an apartment in Seidler's Blues Point Towers and he went on to fly for QF. (He was also the subject of a controversial reinstatement after medical termination). Modesty was not one of his shining virtues, either. Just saying.
