This document discusses, in broad general terms, typical present instrumentation practice for post-overhaul gas turbine engine testing. Production engine testing and engine development work are outside the scope of this document as they will typically use many more channels of instrumentation, and in most cases will have requirements for measurements that are never made in post-overhaul testing, such as fan airflow measurements, or strain measurements on compressor blades. ...Production engine testing and engine development work are outside the scope of this document as they will typically use many more channels of instrumentation, and in most cases will have requirements for measurements that are never made in post-overhaul testing, such as fan airflow measurements, or strain measurements on compressor blades. The specifications for each parameter to be measured, in terms of measurement range and measurement accuracy, are established by the engine manufacturers. ...The specifications for each parameter to be measured, in terms of measurement range and measurement accuracy, are established by the engine manufacturers. Each test cell instrument system should meet or exceed those requirements. Furthermore, each instrument system should be recalibrated regularly, to ensure that it is still performing correctly.

This standard provides considerations for the procurement and design requirements of TE to be used for maintenance and troubleshooting of air transport components in both the shop and/or flight line environment. Although the term TE is used, this standard can be applied to other types of support equipment utilized in the aviation industry, such as shop data loaders, portable maintenance aids, etc.

This evaluation method does not address the effectiveness of detecting tampered type devices. The Test Evaluation Method also describes an Optimized Test Sequence Selection, in which a test sequence is selected that maximizes the CDC utilizing test cost and time as constraints, for any tier level except the Critical Risk Level. ...This information will be supplied to the test laboratory’s customer in both the test report and the Certificate of Quality Conformance (CoQC). ...This document describes an assessment of the effectiveness of a specified test plan used to screen for counterfeit parts. The assessment includes the determination of the types of defects detected using a specified test plan along with the related counterfeit type coverage.

Test equipment practices change over time to better suit the maintenance philosophies of the airlines. ...This standard is an update of ARINC 602 following the introduction of new digital test equipment standards and the publication of ARINC 608A. This standard includes specific references to On-board Maintenance Systems (OMS) and Automatic test Equipment (ATE) used within the maintenance community. ...This standard includes specific references to On-board Maintenance Systems (OMS) and Automatic test Equipment (ATE) used within the maintenance community.

For the purposes of this information report, the discussions of thrust measurement will be limited to axial thrust in single-axis test systems.

The purpose of ARP5448 and its associated slash sheets is to document test methods commonly used to evaluate airframe bearings. These test methods may be referenced in specifications, part standards, purchase orders, etc., when the test is deemed appropriate to the intended use of the bearing by the end user of the bearing. ...This SAE Aerospace Recommended Practice (ARP) establishes methods for testing airframe plain bearings. The purpose of ARP5448 and its associated slash sheets is to document test methods commonly used to evaluate airframe bearings. ...., when the test is deemed appropriate to the intended use of the bearing by the end user of the bearing. These test methods are not intended to encompass every conceivable requirement for an airframe bearing.

Each test method is set out in a uniform format, describing the test purpose, test object, test setup, test waveforms (voltage and/or current), measurements and data recording, test procedure and data interpretation. ...Guidance is provided on how to select the appropriate test or series of tests, and how the test results can be assessed. Natural lightning is a complex and variable phenomenon and its interaction with different types of vehicles may be manifested in many different ways. ...This document is intended to describe how to conduct lightning direct effects tests and indirect system upset effects tests. Indirect effects upset and damage tolerance tests for individual equipment items are addressed in DO-160/ED-14.

This document describes a recommended test procedure to assess the burst characteristics of tires used on 14CFR Part 25 or similar transport airplanes.

If the test cell is designed to test several engine types, the acceptance process should validate upon which engine the test cell will be commissioned ➔ these discussions should take place at the early stage of the design process if not during the bidding phase. ...The paper discusses in general terms the activities required to be undertaken or demonstrated during the establishment of the facility such as: the assessment checks prior to forwarding to the end users site for embodiment into the facility system the establishment of the facility such as trial installations of hardware, functionality checking of lifting transportation and access systems, centerline pull checks, pressure testing of fuel and air start systems, flushing of wet systems and electrical continuity checking. the commissioning of the facility such as instrumentation calibrations, engine starts, engine running, assessment of command and control system, assessment of DAS system, aerodynamic and acoustic surveys. ...If identified, these risks should be translated to specific tests and integrated into the validation plan, either at the factory or on site or both. If the test cell is designed to test several engine types, the acceptance process should validate upon which engine the test cell will be commissioned ➔ these discussions should take place at the early stage of the design process if not during the bidding phase.
