## The airworthiness directive

49-34-01 CONVAIR: Applies to All Model 240 Airplanes Incorporating Activated Reversing Propellers.

Compliance required as soon as possible but in any event not later than August 29, 1949.

Two cases have been experienced in which inadvertent reversal of the propellers occurred in flight during approach for landing.

To minimize the possibility of inadvertent reversal, an item shall be added to the "before landing" cockpit checklist requiring that the reverse throttle stop override handles be checked to assure that they are in the retracted "in" position.
