Item 9Flight 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

QEC does not have a specific position, report X.
Item 17BCM/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.
