This problem is related to the Service Letter 85A: Horizontal Stabilizer Attachment Tube PN190202-37 Inspection and Repair and Airworthiness Directive 75-20-06: Detect Cracks in Either Vertical Side Fuselage Tube Adjacent to Horizontal Stabilizer which required a 100 hour repetitive inspection of the top of the vertical tubes until Bellanca Service Kit SK1234789-0004: Gusset - Stabilizer, Installation and Drag Brace - Stabilizer, Installation is installed. The aircraft in question had the Service Kit installed; the current problem therefore applies to all serial numbers.

Alexandria Aircraft LLC recommends that owners/operators of all Model 14-19-3A, 17-30, 17-31, 17-31TC, 17-30A, 17-31A and 17-31ATC All Serial Numbers have their aircraft inspected for this condition. The inspection should look for cracks on the vertical tubes at Fuselage Station # 7 which support the horizontal stabilizer, paying special attention to the area where the horizontal stabilizer carry-through tube support bracket flange is welded to the vertical fuselage tube. If the Service Kit is not installed, the inspection should also look at the upper portion of the vertical tube as required by Service Letter 85A and AD 75-20-06. This is a potentially dangerous condition and we are trying to get this information out to aircraft owners and maintenance facilities ASAP. We have notified the FAA as we are required to per FAR 21.3: Reporting of Failures, Malfunctions and Defects. We are working with the FAA to resolve this issue. We probably will issue a new service letter and/or revise Service Letter 85A, and the FAA probably will issue a new AD and/or revise AD 75-20-06. The new service letter and AD probably will require a repetitive inspection. DO NOT WAIT FOR THE UPDATED SERVICE LETTER OR AIRWORTHINESS DIRECTIVE; have your airplane inspected ASAP and please report your findings to Alexandria Aircraft LLC.
