AD NUMBER: 2014-20-12

PRODUCT: Certain Alexandria Aircraft LLC (type certificate previously held by Bellanca Aircraft Corp., Viking Aviation, Inc., and Bellanca, Inc.) Models 14-19-3A, 17-30, 17-30A, 17-31, 17-31A, 17-31ATC, and 17-31TC airplanes.

ACTION: Final Rule

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 75-20-06 for the products listed above.

AD 75-20-06 required repetitively inspecting the aft fuselage structure near the top of the vertical side tubing, which connects the horizontal stabilizer carry-through to the upper fuselage longeron, for cracks and installing the manufacturer's service repair kit as a terminating action for the repetitive inspections to repair any cracks found.

Since AD 75-20-06 was issued, the FAA has determined that installing the service kit has not prevented cracks from occurring. The FAA has also determined that all affected airplane serial numbers should be included in the Applicability section.

This AD requires continued repetitive inspections of the aft fuselage structure near the top of the vertical side tubing for cracks and making all necessary replacements of cracked parts. This AD also adds additional serial number airplanes to the Applicability section.

DATES: This AD is effective November 12.
