A Boeing 727-232, Delta Air Lines Flight 488, had a mid air collision with a Cessna U206F, registration XA-GOM (U206-03091), during a VFR approach to Guadalajara, Mexico. None of the three flight crew members, four flight attendants, and 66 passengers onboard the Delta flight were injured and aircraft damage was minor. The Cessna 206 sustained substantial damage and the sole pilot suffered minor injuries. Visual meteorological conditions prevailed. Both airplanes were intending to land on runway 28. On a two mile final approach the Delta captain felt impact and noticed a flash on the side of the airplane. Passengers observed the Cessna pass below the airplane from right to left.
