Probable cause
Separation of the aft, upper, accessory case cowl assembly from the airplane, and inadequate airframe equipment provided by the manufacturer.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The twin-engined turbo-prop airplane was descending from 20,000 feet MSL to 7,000 feet MSL when the left engine aft, upper accessory case cowl separated from its mount. The cowl assemlby struck the left side of the fuselage, the vertical stabilizer, and the horizontal stabilizer. The fuselage strike caused a rapid decompression. The airplane was landed without further incident.
