Probable cause

Improper in-flight planning/decision by the pilot, and his failure to follow wake turbulence avoidance procedures, which resulted in a vortex turbulence encounter. A factor related to the accident was: the pilot's failure to assure the aircraft was loaded within its weight and balance limitations.

Analysis

The Piper PA-28 plt entered left traffic to land on rwy 12 in winds that were variable at 6 KTS. The rwy was 8500' long, but it had a 1200' displaced threshold. At abt the same time, a Boeing 727 (Alaska flt 192) was on an apch to land on the same rwy. The twr ctlr adzd the PA-28 plt of the other traffic & cautioned him abt wake turbulence. The PA-28 was abeam the apch end of the rwy on a close downwind as flt 192 landed. The PA-28 plt was clrd to land & he entered an 'immediate steep bank and descending turn.' Rprtdly, the PA-28 was maneuvered onto final apch abt 100' to 200' AGL, then it began oscillating excessively & crashed. No preimpact mechanical problem was evident. A weight & balance computation showed the PA-28 was abt 150 lbs over its max gross weight limitation & the CG was 3.86 inches behind the aft limit.
