AD/PA-44/19 Control Wheel Attachment 10/2004 DM
Background: The FAA received a report that a Model
PA-28-181 aircraft crashed after the pilot lost control of the
ailerons and elevator. Investigation revealed that the left control
wheel single attachment screw had unscrewed from its nut plate,
which resulted in the control wheel spinning freely on the control
column. Further investigation revealed the screw was too short and
the nut plate lacked proper locking characteristics.
