Commercial Airplanes MD90 Service Bulletin ALERT SummaryNumber: MD90-53A037Original Issue: September 19, 2016 ATA System: 5313 SUBJECT: FUSELAGE - Fuselage, Tail Section - Inspect Cant Station 1520 Bulkhead
THIS DOCUMENT IS SENT TO THE OPERATORS OF RECORD OF THE AIRPLANES SHOWN IN PARAGRAPH 1.A., EFFECTIVITY. IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS DOCUMENT TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS DOCUMENT TO THE NEW OWNER.
CONCURRENT REQUIREMENTS None.
BACKGROUND An MD-90 operator reported cracking of various structure in the MD-90 fuselage Cant Station 1520 Bulkhead.
The cracking was discovered during scheduled maintenance on an airplane with 52,993 flight-hours, and 28,718 flight cycles. The cracks were in the upper left area of the bulkhead, between Longerons 5 and 10, in the web, lower tee cap, and the upper cap and (cap) doubler, in the same plane as the vertical stabilizer rear spar. Boeing analysis has determined that the operational and limit loads cannot duplicate this condition and the root cause is suspected to be the result of a High Load Event(s) based on service experience. Cracking of the bulkhead, if undetected, may result in the inability of the structure to sustain limit loads, and could adversely affect the structural integrity of the airplane.
