REGULATORY TEXT:   69-18-05 CONTINENTAL: Amdt. 39-835. Applies to Models TSIO-520-B (Serial Numbers 145001 through 145618), TSIO-520-D (Serial Numbers 156001 through 156103), and TSIO-520-E (Serial Numbers 165001 through 165493, 165496, and 165497) engines having 300 hours' or more time-in-service, except those engines having turbocharger oil scavenge pumps with P/N 635327 Shaft Gear-Starter, P/N 635328 Body- Scavenge Pump and P/N 635330 Gear-Scavenge Pump, or those engines equipped with P/N 635061-A1 Starter Adaptor and Scavenge Pump Assembly.
Compliance: Unless already accomplished, within the next 100 hours' time-in-service after the effective date of this airworthiness directive, on engines having 300 or more hours' time-in-service, or at or before 400 hours' time-in-service on engines that have less than 300 hours' time-in-service at the effective date of this airworthiness directive, accomplish the following:
To prevent failure of the turbocharger lubricating oil scavenge pump:
Remove P/N 632597 scavenge pump drive gear and P/N MS 35756-3 Woodruff Key and replace with a P/N 636251 scavenge pump drive gear and a new P/N MS35756-3 Woodruff Key. In the P/N 632602 scavenge body assembly drill a .093 inch (3/32) diameter hole to a depth of .31 inch (5/16) in the floor of the gear cavity midway between the center of the gears. Continental Service Bulletin No. M69-8 dated June 11, 1969, refers to the above and provides additional instructions on this modification.
