Unsafe Condition

Certain rivets were incorrectly installed in some areas of the skin lap splices during production because they were drilled with a countersink that was too deep, leading to premature fatigue cracking at certain skin lap splice locations of the fuselage and consequent rapid decompression of the airplane.

Required Actions

Perform initial and repetitive detailed or high frequency eddy current inspections for cracks around the rivets at the upper fastener row of the skin lap splice of the fuselage. Repair any crack found.
