1. GENERAL

1.1. Purpose

WARNING: FAILURE TO APPLY THIS MANDATORY SERVICE BULLETIN MAY LEAD TO AN UNCOMMANDED INFLIGHT ENGINE SHUT-DOWN WHICH, ON A SINGLE-ENGINE HELICOPTER, LEADS TO AN EMERGENCY

AUTOROTATION LANDING.

Avoid divergent rubbing between the piston shaft small labyrinth and the rear bearing support.

1.2. Reason

We have received reports of cases of divergent rubbing between the piston shaft small-diameter labyrinth and 

the rear bearing support, leading to illumination of the “chip” warning light or an external oil leak, or sometimes 

to an engine fire or loss of oil pressure in flight.

This Mandatory SB has been created to strengthen the application of TU 357 modification on ARRIEL 1D - 1D1 

single-engine variants.

1.3. Description

This modification consists of increasing the fit between the piston shaft small labyrinth and the rear bearing 

support, by modifying the piston shaft.

1.4. Approval

The technical information contained in this document has been approved under the Design Organization 

Approval No. EASA.21J.070.

This Mandatory SB is subject to an Airworthiness Directive.

labyrinth using the gauge:

- If the piston shaft small labyrinth does not fit in the gauge (GO), continue to rework.

- If the piston shaft small labyrinth does fit in the gauge (GO), stop the rework.

- If the piston shaft small labyrinth fits in the gauge (NO GO), return the module M03 

with its updated log card to a TURBOMECA-approved repair center.

3.3.2.6.9. Make sure there is no burring on the lips of the piston shaft small labyrinth.

CAUTION: DURING CLEANING, DO NOT ERASE THE ANGULAR MARKING MADE ON 

THE PISTON SHAFT DURING ITS REMOVAL.

3.3.2.6.10. Clean the piston shaft carefully.

CAUTION: INSTALL THE REMOVED PISTON SHAFT ONLY. THE PISTON SHAFT IS USED TO BALANCE 

THE REAR STABILIZER OF THE GAS GENERATOR ROTATING ASSEMBLY DURING NEW
