During a long period El-Al
Maintenance & Engineering Management ignored systematically Boeing
requirements to implement Service Bulletins even there covered by FAA
AD's. (at least 1979-1992)
Rejection of S.B.'s was agreed in
Modifications Committees by participation of Director of Engineering,
Director Major Maintenance, Director of Line Maintenance with the advice
of Deputy Director of Engineering Interior & Structures, under the
imperative of money saving, policy traced by the President of
El-Al.
The most significant
S.B.'s showed in attached list were:
747-54-2062, 747-54-2063,
747-54-2083, 747-54-2102, 747-54-2118, 747-54-2123 and rejected by Mod
Committees No. 384, 370, 374 and 389.
S.B. 747-54-2063 was not
implemented on AXG when this B747 crashed in Amsterdam last October and in
practice El-Al B747 fleet was sporadically provided with this
S.B.
The implementation of S.B.
747-54-2083 (Secondery retention installation - to improve FAIL SAFE
criteria) depends on previous implementation of S.B. 747-54-2063 (Midspar
Fuse Pin inspection and replacement). Also Boeing warned El-Al management
by Service Letters etc.
On the other hand the B747 AXQ was
purchased from QUANTAS in 1988 with S.B. 747-54-2063 implemented in whole
by QUANTAS.
The implementation of S.B.'s can be
easily verified by checking purchase orders from Boeing, because only
genuine parts are allowed to be installed.
The implementation of 17 S.B.'s with
revisions pending to ATA 54 may have conduct to detailed inspection to
monitor fleet integrity and discovering corrosion and cracking on B747
struts and preventing inflight engine separation.
Your people had experienced the
efforts of Dror Finkelstein to convince the investigation authority to
blame Boeing for AXG crash (pretext: wrong design
philosophy).
Boeing may improve,
modify, upgrade the strut design, but El-Al have the obligation to
implement all S.B.'s provided by Boeing, and not trade crew, passangers,
people on ground safety, for a few fuse pins.
Ignorance, indifference,
lack of inspection equipment, corrupt management were the true reason of
AXG crash.
