Improvements
• PSS SB 73-0065 issued in 8/2001 to replace
73-043 on all non-pmux EEC in the field
shown in pictures to the right
• BAE Systems will offer 73-0065 at a
discounted price
• EEC with 73-043 implemented by BAE will
be warranted at 15,000 flight hours or 5
years whichever occurs first (Vs standard
warranty of 1000 flight hours or 1 year) If the
flex fails during the warranty, BAE will
incorporate 73-0065 free of charge
• Recommend that any Non-pmux EEC’s that
did not have 73-043 implemented (S/N
4100-5500) have 73-0065 implemented
• Those that have 73-043 type design (S/N
5501-6749) only have 73-0065 done by
attrition
• IOM SIPEX chip- Vendor process improved
and failures random
• DPM - random failures, no trend
