1.1. Purpose

WARNING : FAILURE TO APPLY THIS MANDATORY SERVICE BULLETIN MAY LEAD TO AN UNCOMMANDED IN

FLIGHT ENGINE SHUT

- DOWN WHICH, ON A SINGLE

- E N GINE 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 bear ing 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 pi ston 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.
