A i r wa ys S . A .TECHNICAL INFORMATION LEAFLET(TIL)Introduction and History:Several Quality findings have already been made against logbook line maintenance entries on the B747 and B777fleet. Most findings are related to appropriate manual and/or related task missing, together with the correct manualrevision. Other findings have been made to incorrect ATA chapters and incomplete description of structural defectsand finally findings were raised due to incorrect accomplishment instructions references.Find hereafter an overview with some examples of correct logbook entry formulation for the most common raisedproblems for:1. Scheduled Line Maintenance:- Technical Order and Engineering Services Instruction- TNT Task Card (with Boeing Task Card Reference)- TNT Task Card (without Boeing Task Card Reference but with AMM reference)- TNT Task Card (without Boeing Task Card Reference and without with AMM reference)2. Unscheduled Maintenance:- Reference to AMM- Reference to FIM- Reference to SRM3. Where to find Document Revisions- me.tay.be- CD/DVD- Manuals4. Documentation of the use of Standard Parts, Raw Material and Consumable5. Incorrect Recording and Follow Up of Repetitive Maintenance out of ADD or DMI, especially with an intervalless then 48H (Daily Check).6. ADD/DMI record sheet time limit calculation7. Incomplete data in the ATL “Authority” field8. Confusion in definition of ADD and DMI9. No EASA Form 1 or Equivalent attached at Component ChangesCompiled by: Fabio CiommoPage 2 of 25TIL: 747-00-010/777-00-005Contact:Original Issued23/10/12Revision: 3Date: 14/06/2016 32 4 239 3312Approved by: N.

A i r wa ys S . A .TECHNICAL INFORMATION LEAFLET(TIL)1. Scheduled Line MaintenanceScheduled Line Maintenance has to be accomplished via a Bill of Work, FORM TEC/04-009 and asdocumented in TPMThe process of certification of Scheduled Line Maintenance has changed since June 2016.Instead of a release to service in the Tech Log for each Maintenance Item per applicable Task Card, a singlerelease to service for the applicable Bill of Work in the Tech Log will be sufficient. Remember always to crossrefer to the CRS Tech Log on the BOW document for administrative follow up. .See an example of such certification:Make sure to enter the revision of the Task Card – deck /AMM/ . as applicable requested on the FormTEC/04-009.When a component replacement is done as a request of the BOW, this also needs to be identified anddocumented via the SRP as a separate entry.Compiled by: Fabio CiommoPage 3 of 25TIL: 747-00-010/777-00-005Contact:Original Issued23/10/12Revision: 3Date: 14/06/2016 32 4 239 3312Approved by: N.

Unscheduled Maintenance:Reference to Maintenance Manual:Refer to the applicable AMM task with the AMM revision used.Reference to Fault Isolation Manual and related Policy:Refer to the applicable FIM task. If not completely performed , refer to the parts accomplished. If the problem is notsolved, despatch per MEL as applicable when the problem is confirmed.Compiled by: Fabio CiommoPage 4 of 25TIL: 747-00-010/777-00-005Contact:Original Issued23/10/12Revision: 3Date: 14/06/2016 32 4 239 3312Approved by: N.

A i r wa ys S . A .TECHNICAL INFORMATION LEAFLET(TIL)Refer to the applicable FIM task. If not completely performed, refer to the parts accomplished. It the problem isintermittent and can not be repeated on ground, and if allowed per FIM, operations can be continued until fault reoccurrs.Refer to the applicable FIM task. If not completely performed, refer to the parts accomplished. It the problem cannot be confirmed, further operation is permitted if the system is confirmed operational per an operational test.Reference to Maintenance Access Terminal (MAT):Whenever the Maintenance Access Terminal is used to interrogate the aircraft on the status of a fault message, thefollowing methodology should be used. As per FIM, if the MAT shows ACTIVE for the maintenance message, the applicable FIM TroubleShooting procedure is to be followed. If the MAT shows LATCHED, do the applicable test per MAT to see if the fault gets unlatched. If the fault messages displays, there is an ACTIVE fault and the related FIM troubleshooting needs to be adhered to. ACTION TAKEN box to be completed as per aboveexamples. If the fault message does not show, the fault was intermittent. ACTION TAKEN shouldrefer to the Applicable MAT test and note the satisfactory result.Compiled by: Fabio CiommoPage 5 of 25TIL: 747-00-010/777-00-005Contact:Original Issued23/10/12Revision: 3Date: 14/06/2016 32 4 239 3312Approved by: N.
