TASK 72-00-32-220-002-B00 LPC/Intermediate Case Module - Examine The Module Outer At Interface B-32, Inspection-002

General

This TASK is for A5 Engines.

The word Reject is used after an interface inspection statement to show that a higher level inspection and possible repair to the damaged part is necessary.

Do the higher level inspection procedure as found in the applicable Chapter/Section/Subject of this manual on the damaged part(s). It is not necessary to do the higher level inspection on parts that are serviceable to the interface inspection standard.

Refer to TASK 72-00-00-200-000 (Examine the modular/non-modular interfaces) (INSPECTION/CHECK-000), before you do this TASK.

The policy that is necessary for inspection is given in SPM TASK 70-20-01-200-501.

NOTE

Special tools are identified in the procedure by the tool primary number.
