Product Focus: Expanding Scope of ARINC 625 Test Equipment

Thus, it can be seen the use of ANZES allows the measurement of the bearing centreline distance to be made at least as, if not more, accurately than Boeing C The existing manual does not give instructions on how to obtain the bearing centreline distance and simply states the acceptable limits for the measurement.

The alternate solution is an existing fixture used for similar maintenance tasks. No change to the task was necessary. The component manufacturers should assure that task requirements are not overstated.

The Transient Nature of Digital Design.

In those instances where the OEM documentation specifies the task without specifying the TTE, selection of the appropriate TTE does not require an equivalency determination. The resulting variety of processes and documentation has resulted in uncertain results from regulatory agency reviews and, in many instances, significant work and rework by Airlines and Repair Stations to meet regulatory agency requirements.

An APIM may be initiated by anyone in the airline community, e.

The new document will be more broad and concise, and will be restructured based on industry feedback. Report 66 Downloads Views. A complex piece of equipment may consist of elements of any Category 1 through 4.

Items may be repeated for additional errata. To provide uniform guidance for airlines and repair stations in developing their processes and documentation for determining functional equivalence of TTE and related procedures used in maintaining aircraft and their associated components that applies to both generic and application specific equipment.


We provide copy of aristocratic masculinity in france in digital format, so the resources that you find are reliable. Problem reporting and corrective action procedures for TTE Equivalency? Maintenance task — High level description of maintenance task at hand e. Category 2 — Generic TTE, task specific This category includes commercial off the shelf COTS tools and other equipment specified by part number, drawing or physical parameters, where the alternate equipment can be shown to produce the same results in the specific task e.

This section provides justification for the allocation of both IA and airline resources. Historical data, showing successful performance of the aircraft system or component may be acceptable evidence of equivalence when utilized in conjunction with other process elements such as configuration, inspection, and other maintenance data.


It was felt that this situation was unachievable. Technical Data Specification for Manufacturers’?

Category 3 — Special information available TTE, sufficient technical 2. Modify dash 7 base by machining slot 11 x 0. Any field that cannot be filled in by the originator may be left blank for subsequent action.

Where possible, the information necessary to establish equivalency should be contained in the appropriate industry standard maintenance documentation. In such cases, the selection of alternate TTE should be based on meeting the original maintenance task requirement, rather than showing equivalency to the OEM-recommended TTE. Test Fixture – L.


On both tools the bearing centreline distance is not measured directly but is rather derived from the difference between a known length and a measured value.

The Testing and Troubleshooting section, Chapter 3. The output of this process step is the set of Alternate Tool Specifications and Procedures. These activities directly support airline goals: How over-specified requirements are corrected? The process described in this section should be applied to Category 2, 3 and 4 TTE. Calibration These procedures have been written presuming that a competent person is performing the calibration. Any project extending beyond a single year will be reviewed annually before being reauthorized.


The process details are documented below.

Product Focus: Expanding Scope of ARINC Test Equipment – Avionics

Inthe working group will define the TSDPs to include test specifications and any additional information needed to implement a test. For instance, includes references to a number of procedures and guidelines to determine equivalency between an independent test provider and OEM test specifications defined in the CMM.

This documentation may include: Drawing dimensions and properties were compared via the equivalency determination process. Subtract measurement obtained in step 1 from Another problem with previous versions of ARINC was that manufacturers would send incomplete information to the operator or third-party TPS provider. In order to provide access to the cockpit printer from several different avionics sources, a single protocol is needed.

Key characteristics of form, fit and function The parameter or value being measured The nominal value of the measurement The tolerances and accuracies required for the task Any special considerations that are required Currently procurable TTE that meet the required specifications Statement in maintenance documentation to allow equivalent TTE where possible 2. ARINC seeks to define test specifications for next-generation aircraft programs, such as the A and B, but also will continue to apply to current and legacy aircraft.
