The suggested similarities of the ASA EMB120 is questionable; (ATLANTIC SOUTHEAST AIRLINES, INC., FLIGHT 2311 UNCONTROLLED COLLISION WITH TERRAIN AN EMBRAER EMB-120, N270AS BRUNSWICK, GEORGIA
APRIL 5,199lAAR92-03 Section 1.16).
While the EMB120 had a runaway prop, it was directly related to abnormal wear conditions and associated abnormal behaviour of the prop hydraulic system. This is unlikely to be the case in a dual failure event as in the APNG event.
