SCOPE
This section provides detailed installation and interconnect instructions for the PS Engi-neering HSA13 Headset Adapter.
Please read this manual carefully before beginning any installation to prevent damage and post-installation problems. Installation of this equipment requires special tools and knowledge.

NOTE: An appropriately rated Certified Aircraft Repair Station must install this equip-ment in accordance with applicable regulations. PS Engineering, Incorporated warranty is not valid unless the equipment is installed by an authorized PS Engineering, Incorporated dealer. Failure to follow any of the installation instructions, or installation by a non-certi- fied individual or agency will void the warranty, and may result in an unairworthy instal-lation.

Certification Requirements
The HSA13 requires specialized knowledge and tools for an effective installation. An ap-propriately rated Certified Aircraft Repair Station must install this equipment in accord-ance with applicable regulations. PS Engineering, Incorporated warranty is not valid un-less the equipment is installed by an authorized PS Engineering, Incorporated dealer. Failure to follow any of the installation instructions, or installation by a non- certified in-dividual or agency will void the warranty, and may result in an unairworthy installation. This article meets the minimum performance and quality control standards required by a technical standard order (TSO). Installation of this article requires separate approval. Re-fer to AC 20-41A for information regarding Substitute TSO Aircraft Equipment.

Unpacking and Preliminary Inspection
Use care when unpacking the equipment. Inspect the units and parts supplied for visible signs of shipping damage. Examine the unit for loose or broken buttons, bent knobs, etc. Verify the correct quantity of components supplied with the list in Section 1.6. If any claim is to be made, save the shipping material and contact the freight carrier. Do NOT return units damaged in shipping to PS Engineering. If the unit or accessories show any sign of external shipping damage, contact PS Engineering to arrange for a replacement. Under no circumstances attempt to install a damaged unit in an aircraft. Equipment re-turned to PS Engineering for any other reason should be shipped in the original PS Engi-neering packaging, or other UPS approved packaging.

Equipment Installation Procedures

Cooling Requirements
Forced air-cooling of the HSA13 is not required. However the unit should be kept away from heat producing sources (i.e. defrost or heater ducts, dropping resistors, heat produc-ing avionics) without adequate cooling air provided.

Mounting Requirements
The HSA13 must be rigidly mounted to the aircraft structure. Installation must comply with FAA Advisory Circular AC 43.13-2A. The unit may be mounted in any area where adequate clearance for the unit and associated wiring bundle exist. The unit may be mounted in any position or orientation. Avoid installing the HSA13 close to high current devices or systems with high-voltage pulse type outputs, such as DME or transponders. To install the HSA13, select a location convenient to the headphone jack providing the input, and the audio panel. The unit may be installed in any position, on a surface that will allow for installation in accordance with AC43-13-2A.

Connector Assembly
The unit connector is a male DB9 connector. This is a crimp-type connector. The AMP Contact Crimping Tool, AMP 601966-1 (or MS22520 equiv.), with Positioning Tool 601966-5 must be used to ensure good quality harness. Ensure that proper strain relief and chafing precautions are made during wiring and in-stallation.

Cable Harness Wiring

Referring to the Appendix, assemble a wiring harness as required for the installation. All wires must be MIL-SPEC in accordance with current regulations. Two- and three-con-ductor shielded wire must be used where indicated, and be MIL-C-27500 or equivalent specification. Proper stripping, shielding and soldering technique must be used at all times. It is imperative that correct wire be used.
Refer to FAA Advisory Circular 43.13-2A for more information. Failure to use correct techniques may result in improper operation, electrical noise or unit failure. Damage caused by improper installation will void the PS Engineering warranty.

Noise
Due to the variety and the high power of radio equipment often found in today’s general aviation aircraft, there is a potential for both radiated and conducted noise interference. Ground loop noise occurs when there are two or more ground paths for the same signal (i.e., airframe and ground return wire). Large cyclic loads such as strobes, inverters, etc., can inject noise signals onto the airframe that are detected by the audio system. Follow the wiring diagram very carefully to help ensure a minimum of ground loop potential. Use only Mil Spec shielded wires (MIL-C-275000, or better).
Radiated signals can be a factor when low-level audio signals are “bundled” with current carrying power wires. Keep these cables physically separated.

Power
The HSA13 is powered by the audio system or radio microphone bias.

HSA13 (P2131) Pin Assignments

Adjustments

The HSA13 is factory adjusted to accommodate the typical requirements for most aircraft configurations. The microphone gain can be adjusted using Mic Gain adjustment pot.

Post Installation Checkout

Operational Checkout
Apply power to the aircraft and avionics. Speak into the microphone associated with the HSA13 and verify proper intercom and radio voice communication.

Final Inspection

Verify that the wiring is bundled away from all controls and no part of the installation in-terferes with aircraft control operation. Move all controls through their full range while examining the installation to see that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in accordance with good practices, with ade-quate strain relief. Ensure that there are no kinks or sharp bends in the cables and coaxial cables. Verify that the cables are not exposed to any sharp edges or rough surfaces, and that all contact points are protected from abrasion.
Complete log documentation, weight and balance computation and other documentation as required. Sample instructions for continuing airworthiness can be found in §6.1.
Return completed warranty registration application to PS Engineering.
