Installation Instructions
The installation process involves several key steps, including aiming the lights, removing existing components, and mounting the new ballast in the forward baggage compartment. The document details how to prepare the mounting area, install the ballast, and connect the wiring to ensure proper functionality of the BOOM BEAM system. Specific instructions are provided for securing the ballast and light housing, as well as for aiming the lights to achieve optimal performance.
Maintenance Requirements
The document emphasizes the importance of including the BOOM BEAM maintenance information in the aircraft's Maintenance Manual. It outlines scheduled maintenance tasks, such as inspecting the mechanical and electrical integrity of the equipment, checking fasteners and cable ties, and ensuring the wiring harnesses are in good condition. Regular inspections are crucial for maintaining safety and performance.
Weight and Balance Information
The weight of the ballast varies depending on the installation: the 35W ballast weighs 0.62 pounds, while the 60W ballast weighs 0.86 pounds. This information is essential for pilots and maintenance personnel to ensure that the aircraft's weight and balance remain within acceptable limits after installation.
Electrical Load Analysis
The electrical load analysis provides critical data on the power consumption of the BOOM BEAM installation. The 35W ballast draws a maximum of 4.1 amperes at startup and 1.65 amperes at steady state. In contrast, the 60W ballast draws 5.9 amperes at startup and 2.4 amperes at steady state. This information is vital for understanding the electrical demands of the new lighting system.
Safety notes
- Ensure all electrical connections are secure and insulated to prevent shorts.
- Follow all installation steps carefully to avoid improper mounting or aiming of lights.

Installation Instructions 1. Prior to light installation, aim the landing and taxi lights against a suitable target board and mark the location of the beams. This will be used later to adjust the new lights. 2. Remove existing lamp, lamp housing and power wires back to the new connection point. 3. The new ballast will be mounted in the forward baggage compartment. The ballast is mounted using Click Bond studs. Temporarily attach 3 Click Bond studs to the LSM-501-103-3 mounting guide using AN315-3R nuts and position the mounting guide as shown in photo 1. The furnished mounting guide may be different in appearance than that shown in the photo. 4. Follow the instructions included with the CB92 adhesive to prepare the stud mounting adhesive and bond the studs in place. Prior to bonding, clean and remove all paint or finishes in the bonding area. Re-apply finishes as required after adhesive has cured.

Re-route and trim existing power and ground wires to a length suitable for connecting to LSM-SCD-007-1 ballast to power wire. Splice landing and taxi wires to LSM-SCD-007-1 wire using M7928/5-4 connectors and cover splices with M23053/5-106-0 shrink tubing. Attach the connector to the ballast. Apply Dow Corning DC4 di-electric compound (or equivalent) to both connectors prior to attaching. See photo 2. Photo #2 7. Install LSM-500-372-11 or LSM-500-372-9 Light Housing Assy to existing mount bracket using supplied hardware. Lightly tighten fastener to allow for light aiming later. 8. Feed ballast end of Lamp/Starter Wire through LH side of nose wheel well following the path of the old wires. It may be necessary to de-pin the ballast side connector. If so, re-pin the connector in accordance with Figure 3. LSM-500-021 Revision G Page 6 of 11 LoPresti Aviation 800-859-4757 / 772-562-4757 or fax 772-228-9750

Photo #6 10. Connect Ballast to Lamp/Starter connector from Light Housing to the ballast. Apply Dow Corning DC4 di-electric compound (or equivalent) to both connectors prior to attaching. Secure all harnesses to existing harnesses and structure using MS3367- 1-9 cable ties per AC43.13-1B. 11. Using either aircraft battery or external power source, apply electrical power to the Boom Beam and observe beam orientation. Aim the light by locating the beam center at the target board set up in Step 1. Due to the optical characteristics of the Boom Beam, we recommend raising the beam aim by 2 – 3 degrees above the stock orientation. Tighten mounting hardware to 85 in-lbs. 12. Fill out Form 337.
