Interesting. Twenty years ago, the min safe altitude for conducting engine air tests was 2500ft - not 2000ft as stated in the report. This was probably a legacy requirement from the JP which had a Hi Key of 2500ft. I did many, and one involved a failure in very similar circumstances - but with a happier outcome. The report also claims that EEC manual checks weren't part of the air test schedule. Again, I disagree - in similar circumstances!
Seems we don't learn!
