GTX 335 ADS-B Out transponder 011-03300-40

011-03300-40 is the exact Part Number for this Garmin GTX 335 ADS-B Out transponder. The unit provides Mode S transponder operation and 1090 MHz extended-squitter ADS-B Out transmission using its built-in WAAS position source. This card is tied to the photographed configuration and its exact suffix; it is not a generic listing for every GTX 335 variant or for a visually similar member of the same product family.

The source listing identifies the GTX 335 as an ADS-B Out unit with a built-in WAAS position source, 14/28 V operation and TSO status. The authentic manufacturer plate visible in the gallery confirms Part Number 011-03300-40, model GTX 335, 14/28 V DC supply and the photographed serial number. These identification details are retained because software level, voltage, bezel, lighting, options and certification can vary across related versions. The Part Number, installed configuration and approved technical data should therefore be checked together before purchase or installation.

Operational role and capabilities

It broadcasts aircraft identity, pressure altitude and approved position information to compatible surveillance infrastructure. The front panel provides squawk-code entry, mode selection, IDENT, VFR recall and status access. The unit must operate as part of a complete approved avionics installation. It cannot replace missing antennas, sensors, data sources, indicators, control equipment or aircraft wiring, and the availability of a feature on the faceplate does not by itself prove that the feature is enabled in a particular aircraft.

The practical value of GTX 335 is its ability to place the required function within direct reach of the crew while exchanging the necessary signals with compatible equipment. Correct operation depends on serviceable power, grounds, antennas, data buses, circuit protection, cooling where required and configuration settings. A fault reported at the unit can also originate elsewhere in that connected chain, so troubleshooting should follow approved maintenance procedures.

Installation and connected equipment

Installation normally requires the approved rack and connectors, transponder antenna, pressure-altitude input, aircraft power and ground, and configuration of aircraft identity and operating parameters. Existing encoders, antennas and wiring must be checked against the applicable Garmin installation data. The rack, backplate, connector kit, antenna, wiring and accessories are not assumed to be included unless they are expressly identified in the quotation. Even when two units share a common panel size, their connector keying, pin allocation, software, power requirements and approval basis can differ.

Before installation, technicians should compare 011-03300-40 with the removed unit, aircraft equipment list, wiring diagrams, installation manual and modification records. They should also confirm available panel space, mounting depth, connector condition, antenna compatibility, circuit protection, lighting, cooling and interface configuration. Any substitution requires approved data; similarity of model names or photographs is not evidence of interchangeability.

Configuration checks for 011-03300-40

The complete suffix in 011-03300-40 is an essential part of the product identity. Database status, embedded options, software level, modification status and certification may affect compatibility even when the hardware looks unchanged. These points are especially important when replacing legacy avionics in an aircraft that has accumulated field modifications or multiple supplemental approvals during its service life.

Incoming inspection should verify the manufacturer plate, housing, connectors, locking mechanism, controls, display or indicator face, cooling provisions and evidence of unauthorized modification. Functional testing should use the approved bench procedure for this model. Installation and return to service remain the responsibility of appropriately authorized personnel working to the aircraft and equipment documentation.

Overhauled condition, ordering and support

This 011-03300-40 GTX 335 is offered in Overhauled condition from partner stock with a six-month warranty. Stock status means that availability is based on a partner-held position and should be reconfirmed when a quotation is requested. The allocated serial number, current test status and documentation available for the specific unit are confirmed before order acceptance.

For an inquiry, specify Part Number 011-03300-40, model GTX 335, required quantity, destination and any installation or documentation requirements. Include the aircraft type and the Part Number of the unit being replaced when possible. Related avionics can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Products shown together there may be functionally connected, but they are not presented as interchangeable unless approved technical data explicitly authorizes the substitution.
