Main Exercise
Purpose: The purpose of this lesson is to show
you how to enter operational start values, performed interval maintenance,
complied modifications and historical stress ratings for a serial that has had
an earlier life.
Purpose: Since one of your aircrafts is in the repair shop
for quite some time you need to lease another aircraft. The leased aircraft is
not new. Therefore, it is essential to enter new life information to be able to
continue maintenance program based on operational data, interval maintenance and
modifications from prior use of the serial.
Windows:

information to be able to continue maintenance program based on operational
data, interval maintenance and modifications from prior use of the serial.
The modification nRENMOD,
through which the reliability of Leg Assy X32LEG7004 is to be improved by
introducing a new strut, has already been performed on the serial structure
X747-900, ACN-10, but not yet entered in the system. The new strut is two-way
interchangeable with the old one. However, since the installation will change
the maintenance requirements, it is necessary to change the part number after
installing the new strut. Consequently, we need to enter the compliance of the
modification leading to the part identity change in the system.
Prerequisite: The
Modification Program leading to a Part Identity Change
exercise must have been performed. Note: When you are creating the serial
range for the modification make sure to enter a range that includes the serial
number ACN-10, where N is your student number.

Purpose: The purpose of this
exercise is to decomply a modification that led to a part identity change on a
serial.
A fault has been discovered on the aircraft
on which the modification nRENMOD was previously incorporated. It appears that
the strut has been damaged, and needs to be replaced. However, the new upgraded
strut that was installed and required to comply with nRENMOD is not available
within an acceptable timeframe. In order to avoid an AOG (Aircraft On Ground),
it is decided to reinstall the original strut type. As a result, the
modification nRENMOD is decomplied and a reversal of the part number change on
the Leg Assy is required.
