ROUTINE JACK
MAINTENANCE BULLETIN
1 OF 1
When using a jack that has a screw extension, it is advisable that the screw extension
be extended as far as possible, and still have the jack roll under the jacking point. If the
screw extension is not properly extended, the aircraft may not be able to be raised to the
desired height.
A periodic check should be made to the screw extension to ensure that the stop is
operating properly to prevent over-extension. To do this, rotate the screw extension
counterclockwise until it stops rotating.
DO NOT FORCE THE SCREW EXTENSION
BEYOND THIS POINT
. If the screw extension does not stop rotating, remove it and
repair the stop.
DO NOT USE WITHOUT THE SCREW EXTENSION STOP WORKING
PROPERLY, AS THE JACK COULD FAIL WITH AN OVER-EXTENDED SCREW
EXTENSION.
