H337PA JETCAL 2000®
Service for UH-60 T700, UH-1H T53, and CH-47 T55 engines
This test set provides test cell equivalent analysis of engine performance while keeping the engine on wing and the aircraft in service.
- Verifies engine performance after installation or maintenance is performed
- Isolates abnormal performance to an engine module
- Specifies and verifies correct maintenance actions by providing before and after diagnostic comparisons
- Allows operators to verify the accuracy of cockpit instrumentation
- Provides engine torque based on thermodynamic engine model for measured parameters to validate torque indicating system
- Provides vibration analysis
- Reduces human error associated with data measurement, recording, and interpretation
- Incorporates Referred Engine Diagnostic Data (REDD®) analysis program. This Howell patented software provides comprehensive thermodynamic analysis that identifies abnormal operation by comparing actual engine operation with expected performance. Produces easy-to-read graphs, charts, and performance reports.
H337H-2 PACT7
Service for the SAAB 340, and CN235
The Performance Analyzer CT7 (PACT7) is an on-wing performance analyzer specifically designed for the CT7 turboprop engine. It incorporates performance equations and algorithms approved by GE.
