CONCURRENT REQUIREMENTS None.
BACKGROUND Two operators reported finding a cracked vertical stabilizer skin at Station Zfs=52.267. Subsequent inspection revealed a severed front spar cap and a cracked front spar web. Cracks were also found on several other MD-80 airplanes, in the vertical stabilizer front spar cap bolt holes. The affected MD-80 airplanes had accrued between 39,749 through 56,212 flight-hours and 32,176 through 44,001 landing cycles when the cracks/anomalies were found. Boeing investigation determined that the skin cracks are due to high loading occurrences, such as, but not limited to, in-flight turbulence. Inspection will determine condition of the vertical stabilizer skin. Incorporation of the leading edge repair will minimize the possibility of crack growth. If not corrected, cracks in the vertical stabilizer leading edge and front spar cap may result in the structure unable to support limit load, and may lead to the loss of the vertical stabilizer.
