Plain English Summary

3/10 complexity

What it does: This AD requires owners/operators of Cessna T210L/M/N and P210N aircraft fitted with Slick Pressurized Magnetos (models 6220 or 6224) to add a BEFORE TAKEOFF magneto check to the AFM: a 1,700 RPM test with limits of 150 RPM maximum drop and 50 RPM maximum differential. If limits are exceeded, the pilot must record the magneto unserviceable and maintenance must disassemble and inspect per AD/CESSNA 210/62.

Who pays and why it matters: Pilots perform the check and mark defects; owners/operators bear inspection and repair costs. Compliance timing and cross‑references to AD/CESSNA 210/62 create procedural and maintenance burdens.

AD/CESSNA 210/63 Slick Pressurized Magnetos - Flight Manual 4/89

Applicability: All Cessna T210L, T210M, T210N, and P210N series aircraft fitted with Slick Pressurized Magnetos model 6220 or 6224.

Requirement: 1. Revise the AFM by adding the following:

“BEFORE TAKEOFF"

Perform 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.

If 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.

Note 1: The aforementioned amendment may be accomplished by inserting a copy of this AD into the relevant section of the AFM.

Note 2: AD/CESSNA 210/62, FAA AD-25-04, and Teledyne Continental Service Bulletin M88-14 also refer.

Compliance: Within 100 hours TIS after 20 April 1989 and concurrent with AD/CESSNA 210/62.

Background: 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.
