THE BLADE FRACTURES WERE HIGH CYCLE TRANSGRANULAR FAILURES EMINATING FROM THE TRAILING EDGE OF EACH BLADE ROOT. A REVIEW OF FAA SDR RECORDS REVEALED 87 SIMILAR FAILURES. SIX EMERGENCY AIRWORTHINESS DIRECTIVES WERE SUBSEQUENTLY ISSUED. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
