The tripartite agreement’s 2003 amendments have the following provision:

“(2)       The Lessee acknowledges and agrees that all flights into and out of the TCCA shall operate between the hours of 6:45 a.m. and 11:00 p.m., with the exception of medical evacuations and other emergency uses.”

Thus any flight before 6:45 am and after 11:00 pm is a violation of the lease.
