Compliance. To minimize the possible adverse affects of undetected rear engine stoppage during take-off, within the next 10 hours' time in service after the effective date of this AD, the following modifications must be accomplished and the following operational procedures will be applicable:
A) Readjust the rear engine idle RPM from 575-625 to 625-675 and readjust idle mixture accordingly.
B) Taxi primarily by use of the rear engine.
C) Initiate all take-offs by advancing the throttle on the rear engine to a point where the normal functioning of the rear engine has been established before advancing the throttle of the front engine.

TAXI AND TAKE-OFF
LEAD WITH REAR ENGINE POWER
CHECK RPM AND FUEL FLOW
NOTE: The operator may make and install a temporary placard using minimum 1/8 inch highletters until the permanent placard is obtained from the manufacturer and properly installed.
