1. Reason for the Job
__________________
A.
A number of incidences of rubber surge duct separations have occured which
in some cases has resulted in damage to the turbine-plenum
insulation-blankets.
B.
The rubber duct separations direct the high velocity load-control
discharge-air over the external surge-duct portion of the turbine plenum. In
some cases this results in localized damage to the insulation blanket. With
the APU inlet temperature above 125 deg.F (51.66 deg.C) the exposed skin
temperature may exceed a 450 deg.F (232.22 deg.C) specification limit
established during aircraft certification.
C.
This repair authorizes the modification of the existing damaged plenum
blanket P/N 3846330-10 to allow the incorporation of the P/N 3846643-1
repair blanket. In addition, this repair provides instructions for the
replacement of the plenum surge blanket P/N 3846330-2 as necessary.
