Aircraft anti-theft device

An aircraft throttle locking device for use with an instrument panel-mounted engine control of the type typically found in light aircraft having a control shaft provided with a hand-grip knob at one end thereof, said shaft being mounted for telescopic movement relative to said instrument panel from an extended engine-inoperable position to a depressed engine-operable position, said device comprising:

• a. an elongated rigid cylindrical member having a longitudinally extending slot therein of a width sufficient to closely receive the control shaft when the latter is in the engine-inoperable position, said member being adapted to substantially enclose said control shaft, and having formed therein:
• 1. a centrally disposed peripherally extending slot;
• and
• 2. a centrally disposed transversely extending slot having a width substantially greater than the width of said peripherally extending slot;
• b. a rigid hollow cylindrical housing integrally formed with said cylindrical member, said housing being open at one end and substantially closed at the opposite end and having a longitudinally extending slot formed in the periphery thereof and an axially aligned radially extending slot formed in the closed end thereof said slots of said housing being of a width to closely receive the control shaft to facilitate positioning of said housing over the hand-grip knob of the aircraft control;
• and
• c. a padlock having a pivotally mounted link portion and a body portion, said body portion being receivable in said transversely extending slot and said link portion being receivable in said peripherally extending slot.

• a. a generally tubular shaped rigid housing receivable over and substantially covering said hand-grip knob said housing being open at one end and closed at its opposite end and said housing provided with a radially disposed slot formed in its closed end and longitudinally disposed slot formed in its periphery, said slots of said housing being of a width to closely receive the control shaft to facilitate positioning of said housing over the hand grip knob;
• b. a generally tubular shaped rigid member integrally formed with said housing and receivable over said control shaft in the engine idle position to substantially enclose said control shaft, said member having a longitudinally extending slot of a width adapted to closely receive the control shaft and being of a length substantially coextensive with the control shaft in its extended position;
• and
• c. locking means for locking said member in an operable position over the control shaft.
