Compliance is required prior to each flight after receipt of this directive until a new transition wastegate assembly P/N LW16858 is installed.
To prevent loss of engine power control due to seized throttle movement, accomplish the following:
1. Prior to each flight check the throttle movement for stiffness or binding as follows:
a. Release the throttle friction lock in the cockpit.
b. Move the throttle from idle to full open and back to idle.
c. If the throttle movement is stiff or binds, replace any wastegate valve or cable assembly with a new assembly in accordance with Lycoming S/B 448.
2. An alternate method of compliance may be approved by the Chief, Engineering and Manufacturing Branch, Federal Aviation Administration, Eastern Region.
The checks in this AD may be accomplished by the pilot. Any corrective action required by this AD must be accomplished by a person authorized by FAR 43.3.
Piper special advisory Telex SA-32RT-300T/32R-301-1 dated February 8, 1980, and Lycoming Service Bulletin No. 448 pertain to this subject.
This AD is effective on August 18, 1980, and was effective upon receipt for all recipients of the letter dated March 17, 1980, which concerned this subject.
