Compliance is required within the next 25 hours time in service after the effective date of this AD, unless already accomplished.

To prevent the possibility of erroneous airspeed indications, accomplish the following:

(a) Inspect the affected airspeed indicators for proper calibration by ensuring that the differential pressure values and tolerances for the indicator's airspeed range conform to those set forth in Tables I and II of SAE Aeronautical Standard AS-391B "Airspeed Indicator (Pitot Static)," dated December 15, 1954, or an FAA-approved equivalent.

(b) If an airspeed indicator inspected in accordance with paragraph (a) of this AD is found not to be in proper calibration, scrap it.

This amendment becomes effective August 4, 1977.
