The reporting custodian usually reports directly to the controlling custodian. Item 9—Flight hours since new. Self- explanatory. Drop all tenths of hours and do not round off or include test cell hours. Operating hours since new should reflect operating hours recorded in the applicable AESR. If less than five digits, add leading zeros; for example, 00104. Item 10—Reporting custodian received from/ transferred to. Enter the UIC of the activity the engine was received from or is being transferred to. Item 11—New controlling custodian trans- ferred to. Identifies the new controlling custodian, by UIC, who will receive the engine. Item 12—Aircraft model. This field identifies the model aircraft in which the engine is being installed or removed; for example, P3C. Item 13—BUNO. Reports the six-digit bureau number (BUNO) of the aircraft that the engine is being installed in or removed from. Item 14—Engine position. Indicates the position in which the engine is/was installed. For example, on a dual (2) engine aircraft, when the starboard (right) engine is removed, the entry should be 2. Item 15—Reason for removal/repair/down- grade. This code describes why an engine is being removed or downgraded, or why the engine needs repair. Figure 9-4 shows a list of authorized reasons for removal, downgrade, and repair codes that are used in engine transaction reporting. Item 16—Quick Engine Change Assembly (QECA). This item is reported to identify engines that are completely assembled with a Quick Engine Change Kit (QECK) and configured for a specific position. If a QEC does not have a specific position, report X. Item 17—BCM/Inspection code. This code (beyond the capability of maintenance) identifies an engine that has been rejected by an I-level maintenance activity. This code identifies engines that I-level activities are not authorized to repair or are not able to repair due to lack of facilities, tools, equipment, technical data, technical skill, or parts. 9-7
