GENERAL INFORMATION

1.1. INTRODUCTION.

1.1.1. GENERAL. This manual contains the description, theory, installation and maintenance for the DK100/DK120/DK130/DK140 Underwater Acoustic Beacon, hereafter referred to as the “DK Series”, manufactured by Dukane Corporation, Seacom Division, 2900 Dukane Drive, St. Charles, Illinois, 60174. See Figures 1 and 2. These beacons have been tested to, and meet, or exceed, all requirements of FAA TSO-C121.

shock and deep-water immersion. As shown on page 6 and 7, the DK Series beacons operate for 30 days when immersed in water. See Figure 2.

1.1.2. SYMBOLS AND ABBREVIATIONS. Symbols and abbreviations used in this manual are in accordance with ANSI Y14.15 and MIL-STD- 12, respectively.

1.2. GENERAL DESCRIPTION.

1.2.1. PHYSICAL CHARACTERISTICS. The DK Series beacons consist of a self-contained battery, an electronic module and a transducer. It is housed in a cylindrical watertight aluminum case capable of withstanding high-G impact

Figure 2. Water Switch Location on Beacon

1.2.2.BEACON MOUNTING. The beacon is mounted to a flight recorder or the airframe by means of a mounting kit (See Section II). This mount consists of an extruded channel, which in conjunction with a securing plate retains the beacon. Figure 1 shows the beacon mounted in the N30A21A Mounting Kit, a strap-type mount. This mount is used for applications where space limitations do not permit the use of the simpler N30A26 Series cradle mount.

1.2.3.BEACON SIGNAL. The beacon is a bat- tery-powered device, which radiates a pulsed acoustic signal into the surrounding water upon activation by its water-sensitive switch. Search operations in water for beacon equipped aircraft can be conducted by utilizing a portable receiver equipped with a directional hydrophone such as the Dukane Model N30A5 Series Locator. This receiver system is operable from small boats or by free-swimming SCUBA divers. Aircraft lost in deep water, i.e., in excess of 6000 feet (1829 meters), require special search gear. Beacon Specifications are listed on page 6 and 7.

SECTION II

INSTALLATION

2.1. GENERAL.

This section describes the installation of the beacon mounting kits and the installation of the DK Series beacons into these mounts.

2.2. INSTALLATION CRITERIA OF THE BEACON.

NOTE

All installations to Cockpit Voice Recorders and Flight Data Recorders should be in accordance with the recorder manufacturer’s approved procedures and hardware.

2.3. SURVIVABILITY.

2.3.1.The beacon location should minimize the probability of physical damage to the device during water impact. The aft mid-section of the aircraft is normally the most desirable location for the beacon, but consideration must be given to environmental conditions outlined in Section 2.4.

2.3.2.The area selected for the beacon mounting should be free of the possibility of heavy equipment tearing loose and striking the device.

2.3.3.Installation should be made to a substantial structural member, but kept as simple as possible and must not weaken the structural member.

2.4. ENVIRONMENTAL.

2.4.1. The DK Series beacon must not be disassembled, crushed, penetrated, incinerated or exposed to temperatures above 160°F (71°C).

2.4.2.The beacon is a battery-powered device and installed shelf life is affected by higher than normal temperatures. Maximum temperature must not exceed 160°F (71°C).

2.4.3.Inadvertent actuation of the water switch by any source of water, such as rain, salt spray, melting ice or snow, head or washroom overflow, foods and beverages, must be avoided.

2.4.4.In order to avoid accumulation of moisture on the water-switch, the device should be mounted with the long axis of the beacon horizontal or with the water-switch facing down. A clean switch will allow moisture to collect into droplets and run off the switch, without activating the beacon.

2.4.5.Honeycomb structure, tarpaulin fabrics, clothing, parachutes, cargo, etc., are soundabsorbing materials. Do not surround the device with these materials and if necessary, remove small areas of such materials from the immediate vicinity.

2.4.6.Any compartment that may not be expected to flood under light impact should not be used. Direct contact between the beacon case and water is necessary for actuation and acoustic radiation.

2.5. MAINTENANCE

In addition to observance of the preceding mandatory considerations, where possible the selection of a mounting location should provide for convenient beacon access during inspection intervals. The proper mounting location should also provide for clearance for removing the beacon from its mounting cradle.
