AGB Change - Engine Run

[slowto280]

CFM 56 AGB change due metal on chip detector.

How long (approx. run time) should engine run be afterwards?

Whatever your manual says.

You will find gearbox replacement procedure in MM 72-00-06 and run procedure afterwards in MM 71-00-00 adj/test. Not familiar with CFM56 but doubt if there is any time given - it will basically be a function test of everything on the gearbox plus leak check. At a guess 20 mins or so. It will probably require 2 starts - IDG will require disconnect and run after reconnect.

Gents, thanks for the input.

I did not personally change the gearbox - just looking for 'general info' (thanks BC!).

As it turns out, not the gearbox...... run was 'clean'.
