WARNING: THE FAILURE TO RESPECT THIS MANDATORY SB MAY RESULT IN AN IN-FLIGHT ENGINE-SHUTDOWN

WHICH ON A SINGLE ENGINE HELICOPTER RESULTS IN AN EMERGENCY LANDING DURING

AUTOROTATION.

Removed only yhe cover (01-010) and identify the P/N of the installed oil pump (01-050): refer to 

Maintenance Manual, Task 79-24-05-900-801

and return the “Compliance certificate for identification of the oil pump” (APPENDIX 2.1)

P/N oil pump: 0319115040

No inspection necessary

P/N oil pump: 0319155050

Remove the oil pump: refer to Maintenance Manual, 

Task 79-24-05-900-801

If the driver remains in module 1 “accessory 

gearbox”: extract the oil pump driver using a magnet.

NOTE: procedure must be performed carefully to 

prevent damage to the driver.

The lubrication device may be removed to facilitate 

accessibility: refer to Maintenance Manual, task 79-21-

00-900-801

The driver remaining on Module 1 does not need to be 

systematically replaced. The driver must be replaced if 

it does not conform with the inspections and assembly 

instructions below.

If the driver remains installed 

on the oil pump: remove the 

pump driver: refer to 

Maintenance Manual, task 79-

- If a non-conformity on the splines is identified during these inspections, contact TURBOMECA.

- Install the pump driver on the shaft of the lubrication device oil pump: refer to Maintenance Manual, 

task 79-24-05-900-801.

Note: make sure that the pump driver is firmly attached to the pump shaft. A holding force must 

be observed by manually pulling on the driver. In addition, the driver does not detach when the 

oil pump is positioned on a vertical axis, with the driver at the lowest point.

- Install the oil pump: refer to Maintenance Manual, task 79-24-05-900-801. The engine or module on 

which it is being installed must be positioned horizontally.
