Unsafe Condition
Cracking of the hole(s) of the horizontal flange of the keel beam, which could result in rupture of the keel beam, and consequent reduced structural integrity of the airplane.
Required Actions
Inspect for cracking of the hole(s) of the horizontal flange of the keel beam, and repair if necessary. Perform a one-time ultrasonic inspection for cracking at fastener hole Nr 6. The repetitive inspections are to be done at intervals ranging between 7,800 flight cycles or 50,900 flight hours and 10,700 flight cycles or 35,200 flight hours. The compliance times for the one-time ultrasonic inspection are the latest of (1) 21,000 flight cycles or 60,600 flight hours and within 2,400 flight cycles or 24 months; or the latest of (2) 22,100 flight cycles and 64,400 flight hours, or within 1,300 flight cycles or 24 months. The repetitive inspections may be terminated if certain conditions are met.
Compliance Time
The earliest compliance time for the initial rotating probe inspections is the later of (1) before 10,400 total flight cycles or 67,800 total flight hours, whichever occurs first; and (2) within 24 months or 14,590 flight cycles or 43,790 flight hours, whichever occurs first. The latest compliance time for the initial inspections is the later of (1) before 20,800 total flight cycles or 67,900 total flight hours, whichever occurs first; and (2) within 24 months or 21,180 flight cycles or 63,560 flight hours, whichever occurs first.
Affected Aircraft
Airbus Model A330-201, -202, -203, -223, -243, -301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes; and Model A340-200 and -300 series airplanes.
