Anyone out there familiar with this SSA Sikorsky supposedly sent out in September? Looks like EASA is very upset that the company is suggestions RFM changes that have not been approved. Sikorsky tells me they have no idea what EASA is getting at here....
EASA Safety Information Bulletin
SIB No.: 2009-05
Issued: 17 March 2009
Subject: Sikorsky S-92A Main Gearbox (MGB) Malfunctions.
Ref. Publications:
Sikorsky Safety Advisory SSA-S92-08-006 dated 26 September
2008; and Sikorsky CCS-92-AOL-09-0008 dated 14 March 2009.
Description:
The Sikorsky Aircraft Corporation published SSA-S92-08-006 to
inform owners and operators of impending Rotorcraft Flight Manual
(RFM) changes, prompted by service difficulties with the S-92A
MGB lubrication system. More recently, CCS-92-AOL-09-0008 was
published to inform owners and operators about a recent accident
with an S-92A helicopter. The latest advisory document contains
reminders of existing Sikorsky service publications that
recommend specific action(s) that may or may not be related to the
root cause(s) of the latest accident. CCS-92-AOL-09-0008 also
specifies that ‘compliance’ with Sikorsky Safety Advisories is
‘essential’.
After reviewing the information and pending the investigation,
EASA supports the recommendations contained in CCS-92-AOL-
09-0008, with the exception of SSA-S92-08-006. This advisory
document refers to RFM changes that have not yet been approved
by the FAA. In fact, the SSA specifies the ‘corrective action’ as
“Ensure all flight crews become familiar with the RFM changes
when received”. This SIB is published to ensure that all owners
and operators of affected rotorcraft, registered in European Union
Member States or associated countries, are aware that the
procedures specified in SSA-S92-08-006 have not been approved
by FAA or EASA. The relevant emergency procedures in the
approved RFM must be observed.
Applicability:
Sikorsky S-92A helicopters, all serial numbers.
