Common Information
TASK 71-51-44-200-301 Ignition Supply Harness - Examine The Harness, Inspection-001
General
This TASK gives the procedure for the inspection of the ignition supply harness. For other ignition supply harness parts refer to Inspection-000 TASK 71-51-44-200-300 and the Component Maintenance Manual - Miscellaneous Mechanical Components, Inspection-000 TASK 71-51-44-700-300.
Fig/item numbers in parentheses in the procedure agree with those used in the IPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the IPC.
A ** following repair referenced in this inspection indicates that the repair is not yet published in the current revision of the manual and the part must be rejected. Contact IAE for additional information concerning FAA approved repair date.
The policy that is necessary for the inspection is given in SPM TASK 70-20-01-200-501.
All the parts must be cleaned before any part is examined. Refer to Cleaning-000 TASK 71-51-44-100-300
All parts must be visually examined for damage, corrosion and wear. Defects that are not identified in the procedure must be referred to IAE.
The procedure for those parts which must have a crack test is given in relevant SUBTASK. Do the crack test before the part is visually examined.
Do not discard the part until you are sure there are no repairs available. Refer to the instructions in Repair before a discarded part is used again or oversize parts are installed.
Parts which must be discarded can be held although no repair is available. The repair of a discarded part could be shown to be necessary at a later date.
All parts must be examined to make sure that all the repairs have been completed satisfactorily.
The practices and processes referred to in the procedure by the TASK/SUBTASK numbers are in the SPM.
