JACKING
1. DESCRIPTION
Three jack points, located at each wing tiedown and empennage tiedown, are provided to perform mainte-
nance operations. Tie-down rings must be removed and replaced with jack points prior to lifting. Jack
points are stowed in the baggage compartment. The airplane may be jacked using two standard aircraft
hydraulic jacks at the wing jacking points and a weighted tailstand attached to the tail tiedown.
