Supersedence is read from the Federal Register text of the newer AD — the FAA publishes no structured field for it — and names only ADs held in our index.

Requires repetitively inspecting the elevator control tabs for discrepancies, taking necessary corrective actions to bring all discrepancies within acceptable tolerances, and reporting certain inspection results to the FAA.

Full official abstract

We are superseding an existing airworthiness directive (AD) for all Viking Air Limited (type certificate No. A-815 formerly held by Bombardier Inc. and de Havilland, Inc.) Model DHC-3 airplanes. That AD currently requires repetitively inspecting the elevator control tabs for discrepancies, taking necessary corrective actions to bring all discrepancies within acceptable tolerances, and reporting certain inspection results to the FAA. This new AD retains the actions currently required in AD 2011-05-02 and removes the Supplemental Type Certificate (STC) SA01059SE condition in the Applicability section. This AD was prompted by our determination that we inadvertently omitted certain airplanes from the Applicability section. We are issuing this AD to correct the unsafe condition on these products.
