SIB No.: 2016-16R1
Issued: 24 May 2017
Subject: AMSAFE Restraint Systems – Jammed Cockpit Seat Belt Buckles
Revision:
This SIB revises EASA SIB 2016-16 dated 14 October 2016.
Ref. Publications:
AMSAFE Alert Service Bulletin (ASB) 1150004-25-A01 Revision 7 dated 15 March 2017.
IPECO SB 063-25-11 Revision 2, dated 09 November 2016.
Applicability:
AMSAFE Rotary Buckles (RB) Part Numbers (P/N) 1150004-Series (see Figure 1 below),
manufactured between December 2013 and April 2016 (inclusive).
The affected AMSAFE RBs are known to be installed on, but not limited to, IPECO pilot and co-pilot
seat belt restraint systems assemblies (RSA), having the following P/Ns:
- 0150001-( )-( )
- 1180002-( )-( )
- 1180003-( )-( )
- 1180010-( )-( )
- 1180011-( )-( )
These RSA are known to be installed on, but not limited to, ATR 42 and ATR 72 aeroplanes.
Description:
Reports were received by EASA of occurrences where pilots were unable to release their seat belts
buckles. This issue occurred on RSA, identified as IPECO P/N 1180010-( )-( ), equipped with
AMSAFE RB P/N 1150004-Series. Investigation conducted by AMSAFE on RB P/N 1150004-Series
concluded that the thread locker may not have been properly applied on the RB central screw.
This is a quality production issue, which may lead to the central screw progressively unscrewing,
up to a point where it would prevent the unlocking of the seat belt buckle.

EASA SIB No.: 2016-16R1
Since EASA SIB 2016-16 was issued, AMSAFE determined, following new in-service events reported
on seat belt buckle outside the initial batch, that the range of impacted seat belt buckles is to be
extended. This SIB is revised accordingly.
At this time, the safety concern described in this SIB is not considered to be an unsafe condition
that would warrant Airworthiness Directive (AD) action under Regulation (EU) 748/2012, Part
21.A.3B.
Recommendation(s):
EASA recommends operators to accomplish the actions as specified in AMSAFE ASB 1150004-25-
A01, Revision 7. IPECO SB 063-25-11 Revision 2 also contains useful information and instructions
concerning this safety subject.
