Verify fuel supply /
pressure
Connect FADEC Service Tool

"P-Rail Tar". If capable, do so by
generating graph. Deviation must
be 50/-70 bar.
Proceed to Code 35, "Too Low
Pfuel in Flight"

Check manifold
pressure
Connect FADEC Service Tool
while performing ground run and
reproducing the problem (at max.
power). Compare "MAP" to

generating graph. Deviation must
be /- 50 mbar
Proceed to Code 30, "Lack of

Connect FADEC Service Tool
during test flight, reproducing the
problem (at max. power).
Compare "MAP" to "LiMAPTar"/ If
capable, do so by generating
graph. Deviation must be within
