The airworthiness directive
80-13-08 VARGA (Morrisey): Amendment 39-3808. Applies to Varga (Morrisey) Model 2150 and 2150A airplanes certificated in all categories.
Compliance is required as indicated, unless already accomplished.
To prevent possible reversal of throttle command, accomplish the following:
(a) Within 50 hours' time in service from the effective date of this AD, or at the next annual inspection, whichever occurs sooner, install a throttle stop to limit the allowable throttle movement in accordance with Varga Service Letter SL 2150A-1 dated April 29, 1980. Adjust throttle linkage so that the crank arm does not come closer than 1/8 inch to the stop with the throttle in the most forward position. After installation, conduct engine ground power test to determine that full engine take off power is available.
(b) Alternative inspections, modifications or other actions which provide an equivalent level of safety may be used when approved by the Chief, Aircraft Engineering Division, FAA, Western Region.
This amendment becomes effective June 27, 1980.
