"While the aircraft technician was performing an A-B inspection, he found the right and left aft fuselage bleed airline attach brackets pulled from the aft fuselage bulkhead, resulting in cracks in the bulkheads at the frame station 329.92. The technician recommend inspecting this area thoroughly at each inspection and contacting Hawker Beechcraft for repair options.

Editor’s Note: (Cycles indicated: 3,225. Reference your submission in last December's Alerts. The SDRS database only returns two entries for this bulkhead P/N; this one will make three. At least six entries are missing from the database! I cannot promise that nine would effect a change any faster than three, but it will provide an increasing validity to the defect observation. If you have a log that will burn, don't waste it. Throw it on the fire—Ed.) Part Total Time: 2,967.6 hours.
