Mission Oaks National Bank in Temecula, Calif., hopes to become the lender of choice for pilots shopping for general aviation airplanes and, in some cases, helicopters in the western U.S. from New Mexico to Washington, as well as Nevada and Arizona, and occasionally other states. The bank will consider loans on aircraft valued up to $3.5 million. Veteran aviation lender Juan Alonzo has been hired to manage the new aircraft loan department.
