ISSUE:
SUMMARY:
If lift system hydraulic pressure is lost the wheel chair lift assembly can drop to
the floor of the compartment. When the Deploy command is activated the lift
will drag on the floor and tear out the existing landing block.
Performing this procedure will replace the existing landing block with a new
design landing block that eliminates the issue.
