Description

CFM56-5B A320/A321 Quick Engine Change Kit Instruction Manual (QECKIM)

This Quick Engine Change Kit Instruction Manual (QECKIM) delivers the complete, step-by-step procedures for installing the QEC kit onto a bare CFM56-5B engine as used on Airbus A320 and A321 aircraft. Published by Rohr, Inc., a subsidiary of Goodrich Corporation operating as Goodrich Aerostructures, in May 2019, this manual is configured specifically to QEC Kit No. 642K9001-275, Serial Number 43142677 OVH. Every figure, torque value, and assembly sequence in this 670-page document is written to help technicians complete a correct, airworthy powerplant buildup.

The manual is organized under ATA 71-00-00 (Power Plant) and follows a logical assembly sequence from the demountable powerplant through engine buildup, electrical system brackets, engine mounts, and every major system installation. Each figure is represented by one or more illustrations, with index numbers cross-referenced to the parts lists and assembly tasks.

The CFM56-5B Quick Engine Change Kit Instruction Manual is a one-time-use document written to the latest serialized production configuration of the QEC Kit No. 642K9001-275. It will not be revised and is not a service maintenance document. Once the QEC kit is installed on the bare engine, technicians should refer to the CFMI Engine Shop Manual and Engine IPC for subsequent assembly, disassembly, and service work.

What This Manual Enables You to Do

This QECKIM gives technicians the full assembly sequence for the CFM56-5B QEC kit, from the initial mounting of electrical system brackets on the fan case flanges through the final installation of the inlet cowl, centerbody, and core nozzle. The procedures cover every major engine system — hydraulic, fuel, lube oil, starter, drain, pneumatic, anti-ice, and fire detection — along with the integrated drive generator, forward and aft engine mounts, and the complete fan section electrical harness routing.

IMAGES PREVIEW

Each installation figure lists the required parts by index number, with tools, equipment, and consumables identified before every procedure. Torque values are given in both pound-inches and Newton-meters, and electrical resistance limits are specified where bonding is required. The manual also includes detailed safety warnings for cadmium, asbestos, beryllium, ceramic fibers, hexavalent chromium, crystalline silica, and lead, plus a complete consumables list and vendor list for sourcing materials.

Because this manual is written to the exact serialized configuration of QEC Kit S/N 43142677 OVH, the part numbers, buildup procedures, and installation sequence are specific to that kit. It is not a generic CFM56-5B manual and should not be used to install a QEC kit with a different serial number, as component part numbers and procedures may differ between kits.

Why Correct Procedures and Specifications Matter

Quick engine change kit installation demands precision. A bracket installed at the wrong flange hole, a torque value applied incorrectly, or a harness routed without the proper clearance can lead to vibration damage, chafing, electrical faults, or worse. This manual provides the exact flange hole identifications, torque sequences, electrical resistance limits, and clearance requirements that Rohr engineered for this QEC kit. Following them protects the engine, the aircraft, and the technicians performing the work.

The manual also includes important cautions about chemical exposure and proper handling of hazardous materials — critical information for anyone working with cadmium-plated fasteners, sealants, primers, and other aviation-grade chemicals.
