AD: Viking Air

AD NUMBER: 2011-12-02

MANUFACTURER: Viking Air Limited Model DHC-3 (Otter) Airplanes
SUBJECT: Airworthiness Directive 2011-12-02

SUMMARY: This AD is for the products listed above that are equipped with a Honeywell TPE331-10 or -12JR turboprop engine installed per Supplemental Type Certificate (STC) SA09866SC.

This AD requires incorporating revised airspeed limitations and marking the airspeed indicator accordingly. There is also a requirement for the installation of a temporary placard until the airspeed indicator can be modified but not to exceed a certain period of time.

This AD was prompted by analysis that showed that airspeed limitations for the affected airplanes are not adjusted for the installation of a turboprop engine as stated in the regulations.

The FAA is issuing this AD to prevent the loss of airplane structural integrity due to the affected airplanes being able to operate at speeds that exceed the speeds established in the Federal aviation regulations for safe operation.
