Tulsa County Sheriff's Office spokesman Justin Green says the plane arrived in Miami from Bogota, Colombia, on Sunday. It was flagged for maintenance and sent later that day to Tulsa International Airport, where American Airlines has a maintenance base.

While working on the nose gear, an airline employee noticed what looked like a clump of insulation or a brick-like object and called the sheriff's office to inspect the suspicious find.

Authorities discovered seven bricks of cocaine, worth at least $14,000 a pound.

Green says the case has been turned over to the U.S. Drug Enforcement Administration in Miami.
