Accident Details
The accident involved a Piper PA-28 and a Boeing 727 operated by Alaska Airlines as Flight 192, both on approach to land on runway 12 at an undisclosed airport. The runway was 8,500 feet long with a 1,200-foot displaced threshold. Winds were variable at 6 knots.
Sequence of Events
The Piper PA-28 pilot entered a left traffic pattern to land on runway 12. Around the same time, Alaska Flight 192 was also on approach to the same runway. The tower controller advised the PA-28 pilot of the other traffic and cautioned about wake turbulence. The PA-28 was abeam the approach end of the runway on a close downwind when the Boeing 727 landed.
The PA-28 pilot was cleared to land and subsequently entered an immediate steep bank and descending turn. Reportedly, the PA-28 was maneuvered onto final approach at an altitude of about 100 to 200 feet above ground level (AGL), then began oscillating excessively and crashed. No preimpact mechanical problem was evident.
Weight and Balance
A weight and balance computation showed the PA-28 was approximately 150 pounds over its maximum gross weight limitation, and its center of gravity (CG) was 3.86 inches behind the aft limit.
