More than ever before, aircraft owners must be certain their aircraft are locked and secured. An STC by SiriusWings enables owners of 172 Series, 182 Series, 180s, 185s, 206, and 210 Series Cessnas to add heightened security to their aircraft with a window lock. This window lock is flush-mounted and positioned on the left door window. The STC documents are available for $125. The locks are purchased separately for approximately $8.00 each. Time for installation is approximately four to five hours which includes installing the window lock and changing the door and baggage door locks which are covered by the STC.
