Mechanics' Liens—Aircraft.

1937, ch. 247, sec. 51.

68. Whenever an aircraft or any part thereof is left by the owner or
by any other person with his authority, express or implied, in the custody
of any corporation, firm or individual, association, or person for repair,
rebuilding, storage, or for the purpose of having furnished for or on
account of the same any parts, accessories, or tires, the corporation, firm,
individual, association or person in whose custody said aircraft or part
thereof is left for all or any of the purposes aforesaid, shall have a lien
on said aircraft or part thereof for all charges so incurred, and may law-
fully retain the same until said charges have been paid, or until said lien
is extinguished or discharged as hereinafter provided. Said lien shall be
superior to the rights of the holders of conditional sale contracts, bills
of sale, chattel mortgages or other hens or claims of any kind which are
not theretofore executed and recorded or filed for record as required by
law, but shall be subordinate thereto where the same have been theretofore
executed and recorded as required by law. Surrender or delivery of any
aircraft subject to the lien aforesaid shall operate as a waiver or extinguish-
ment of the same as against third persons without notice thereof, but shall
not operate as such waiver or extinguishment as against the owner, or as
against third persons with notice.

1937, ch 247, sec 52

69. Should the owner dispute the amount of the charge, or any part
thereof, for which the lien is claimed as aforesaid, such dispute may be
determined by appropriate legal proceedings, and the institution of any
such legal proceedings shall operate as a stay of execution under said
lien until the amount thereof shall have been judicially determined, or
the owner of such aircraft shall have the right to immediately repossess
himself of his said aircraft upon filing a good and sufficient corporate
bond, in double the amount of said claim, with the Clerk of the Circuit
Court for the County, or with the Clerk of the Superior Court of Balti-
more City, where the corporation, firm, individual, association, or person,
claiming such lien may have repaired or stored said aircraft, which said
bond shall be approved by the Clerk of said Court, and which said bond
shall be conditioned upon the payment of the full amount of any final judg-
ment which may be recovered upon such claim, together with interest,
and all costs incident to any such suit, and any costs and expenses which
may have been incurred in connection with the enforcement of such lien up
to the time that such lien claimant is notified of the filing of such bond.
