Service Information: Evaluating leaks at the engine

Engine

166.9, 457.9, 470.9, 471.9, 473.9, 541.9, 542.9, 668.9, 902.9, 904.9, 906.9, 924.9, 926.9, 934.9, 936.9

When assessing leaks at the seals and radial shaft sealing rings on the engine, it is usual these days to use the terms "leaktight, slight leak and severe leak".

As these assessments are not defined, difficulties of interpretation and communication can occur.

For these reasons, we have the following general information:

AH01.00-N-0200-01A

for evaluating leakages.

This general information is intended to support you when assessing leakages.

Picture no., etc.
