Revise the AFM by adding the following:\n\n“BEFORE TAKEOFF\"\n\nPerform a magneto check of each engine at 1,700 RPM as follows: Move ignition switch first to R position and note RPM. Next, move switch back to BOTH, to clear the other set of plugs. Then, move switch to the L position, note RPM and return the switch to the BOTH position. RPM drop should not exceed 150 RPM on either magneto or show greater than 50 RPM differential between magnetos. If there is doubt concerning operation of the ignition system, RPM checks at higher engine speed will usually confirm whether a deficiency exists.\n\nIf the magneto check exceeds either of the above limits, both magnetos must be disassembled and inspected in accordance with requirement 2 of AD/CESSNA 210/62; an entry to this affect is to be made in the maintenance release by the pilot.\n\nNote 1: The aforementioned amendment may be accomplished by inserting a copy of this AD into the relevant section of the AFM.\n\nNote 2: AD/CESSNA 210/62, FAA AD-25-04, and Teledyne Continental Service Bulletin M88-14 also refer.\n\nCompliance: Within 100 hours TIS after 20 April 1989 and concurrent with AD/CESSNA 210/62.\n\nBackground: The Before Take Off check introduced by this AD requires that any magneto which exceeds the limits specified in the check must be placed unserviceable in the maintenance release by the pilot and subsequently disassembled and inspected in accordance with AD/CESSNA 210/62.","sortOrder":0}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
