Aircraft Security LLC started in 1981 by selling high security replacement door locks for single engine aircraft. Today, we manufacture high security Medeco locking systems for nearly all aircraft currently being manufactured. We are standard equipment with seven different aircraft manufactures on eighteen different models. Additionally, we are offered as options with six different manufactures on more than ten models. We work along side each of the OEMs to design and manufacture Medeco locks for both new and aftermarket aircraft. Our locking systems are either installed under the aircraft Type Certificate on new aircraft, the Completion Center's approval or FAA/PMA for after market aircraft.
