INSPECTION of Alexandria Aircraft LLC Bellanca Service Letter 85, Revision B, dated April 8, 2004. (2) Models 14-19-3A, 17-30, 17-30A, 17-31, 17-31A, 17-31ATC, and 17-31TC airplanes, all S/Ns not referenced in paragraph (g)(1) of this AD (airplanes not previously affected by AD 75-20-06): Before or upon the accumulation of 300 hours TIS or within the next 25 hours TIS after November 12, 2014 (the effective date of this AD), whichever occurs later, and repetitively thereafter at intervals not to exceed 100 hours TIS, visually inspect the aft fuselage truss for cracks as specified in paragraph 4. INSPECTION of Alexandria Aircraft LLC Bellanca Service Letter 85, Revision B, dated April 8, 2004.
Unsafe condition
This AD was prompted by reports that cracks are still being found in the vertical side fuselage tube (fuselage station 7) in the area near the upper fuselage longeron on airplanes that have had Bellanca Kit SK1234789-0004 installed, which is a terminating action for the repetitive inspections required in AD 75-20-06. We are issuing this AD to detect and correct cracks in either vertical side fuselage tube (F.S. 7), which is adjacent to the horizontal stabilizer carry-through, in the area near the upper fuselage longeron to prevent failure of the horizontal stabilizer. This failure could cause reduced structural integrity of the fuselage and result in loss of control.
Affected ADs
This AD supersedes AD 75-20-06, Amendment 39-2372 (40 FR 43484, September 22, 1975, (“AD 75-20-06”)).
