COMPLIANCE: Required as indicated unless already accomplished.

To preclude failure of the engine oil pressure and scavenge pump drive shaft and resulting oil pressure loss caused by turbocharger oil scavenge pump ingestion of failed turbocharger thrust bearing anti-rotation pins, within the next 10 hours' time-in-service after the effective date of this AD, accomplish the following:

A) Check the Cessna P/N C295001-0101 (AiResearch P/N 406610-5) turbocharger nameplate to determine if the serial number is HI0101 through HI0175. The owner/operator may perform serial number check only provided any cowling disassembly/reassembly is accomplished in accordance with applicable Cessna Service Manuals.

B) If the serial number on the turbocharger nameplate is not one of those specified in Paragraph A), make an entry in the aircraft maintenance records indicating compliance with this AD and no further action is required.

C) If the serial number on the turbocharger nameplate is one of those specified in Paragraph A):

1. Remove the turbocharger oil return hose and fitting and visually inspect to assure that a failed thrust bearing anti-rotation pin is not trapped in the hose, check valve, or oil scavenge pump inlet.

2. Replace the turbocharger in accordance with the applicable Cessna Service Manual with a replacement unit which is not one of those listed in Paragraph A).

D) Within 24 hours time-in-service after the turbocharger replacement required by Paragraph C) of this AD, and prior to disposition of the turbocharger, contact your local Flight Standards District Office, General Aviation District Office or Engineering and Manufacturing District Office for turbocharger disposition procedure.

E) Airplanes may be flown in accordance with FAR 21.197 to a location where the replacement required by Paragraph C) may be accomplished.

F) Any equivalent method of compliance with this AD must be approved by the Chief, Engineering and Manufacturing District Office, Federal Aviation Administration, Room 238, Building No. 2299, Mid-Continent Airport, Wichita, Kansas 67209.

This amendment becomes effective on March 28, 1980, to all persons except those to whom it has already been made effective by airmail letter from the FAA dated February 25, 1980.
