C.4 Testing Requirements

C.4.1 General

After overhaul and assembly, the Contractor shall test the US Navy LM2500 PBT gas generator assembly in accordance with the testing and the acceptance/rejection criteria cited in the latest revision of the appropriate US Navy LM2500 depot level technical manuals. The gas generator shall be tested to ensure that it will operate properly when installed shipboard. US Navy LM2500 PBT gas generators shall be tested in accordance with the testing procedures outlined in Chapter 13 of the US Navy LM2500 technical manual S9234-AB-MMD-030/LM2500 latest revision. US Navy testing procedures require that the exhaust nozzle cold conical throat area measurement (AE8) is within 211 sq. in. +/- 1 sq. in.

The US Navy acknowledges that commercial Contractors routinely correct test cell data to isometric conditions for the purpose of evaluating performance data. US Navy LM2500s must operate in high ambient conditions worldwide to support mission requirements. The US Navy rates its engines at 100 degrees Fahrenheit conditions to ensure performance in all operating environments. If the Contractor's exhaust nozzle cold conical throat area measurement is not 211 sq. in. +/- 1 sq. in. during performance testing, the performance data shall be corrected to the standard US Navy day and 211 sq. in. for data correction and extrapolation to the standard US Navy day IAW CDRL A005.

The gas generator shall be tested and performance data corrected to the standard US Navy day, ambient temperature of 100 degrees Fahrenheit and ambient pressure of 14.7 psia. The overhauled gas generator performance data, after corrected to a 100 degree Fahrenheit day, shall meet or exceed the criteria stated in the testing section of the US Navy LM2500 depot level technical manual.

The Contractor shall notify NSWCPD Code 423 fourteen (14) calendar days prior to any gas generator testing, in order for a Government representative to be present during the testing IAW CDRL A005.

Within five (5) working days after completion of performance test of the US Navy LM2500 PBT GG, the Contractor shall provide performance data corrected to the standard US Navy day, ambient temperature of 100 degrees Fahrenheit and ambient pressure of 14.7 psia IAW CDRL A005.

Data from any and all testing will be enclosed in the gas generator overhaul repair report produced by the Contractor

IAW CDRL A003.

Any components that are deemed unsatisfactory by the US Navy inspectors shall be replaced before the US Navy accepts the gas generator. The rejection of components and/or the classification of unsatisfactory will be in accordance with the criteria specified in the US Navy technical manuals listed in Section C.2.2 of this document. Components that are deemed unsatisfactory shall be replaced at no additional cost to the US Navy.

Subsequent to the acceptance test and borescope inspection, the gas generator shall be cleaned in accordance with procedures outlined in US Navy LM2500 depot level technical manual S9234-AB-MMD-010/LM2500 Chapter 3 or US Navy approved equivalent standard commercial procedures.

C.6 Visitations by the Government
