Professional Avionics Testing, Ready for the Hangar or Flight Line
Aviation maintenance teams need test equipment that is both comprehensive and truly field-ready. The RBI9300TDR Avionics Measurement Supply Drawer Case Kit from Red Box Tools delivers exactly that: 68 carefully selected conventional and avionic-specific items packed into a single, highly durable case. Built for the realities of the aviation service environment, the kit supports insulation resistance, voltage, current, frequency and continuity measurements across a wide range of aircraft systems.
The case itself is manufactured from tough polypropylene that resists scratches, dents and impact. It is airtight, waterproof and dustproof, and will remain buoyant if it ends up in water—practical protection when working around aircraft, ground equipment or remote locations. With external dimensions of 630 mm × 500 mm × 305 mm and a total weight of 25 kg, the kit is substantial enough for serious professional use while remaining transportable.
What’s Inside the Kit
The RBI9300TDR is organised for efficiency. Key contents include:
- A full range of aero leads in 12, 16, 20 and 22 AWG configurations (male-to-male, female-to-female and mixed), plus specialised GTA aero leads
- Silicon test leads (1.2 m and 1.5 m) in red and black
- Lantern prods, thin spikes, 4 mm safety plug adapters, coaxial BNC cables, 4 mm couplers and small crocodile clips
- BNC coax kit covering multiple connector combinations (BNC/F, BNC/M, BNC/J, BNC/T, etc.)
- A Fluke 1587 Hi-Performance Insulation Multimeter customised for the avionic field, capable of insulation resistance measurement, voltage testing up to 1000 V, TRMS AC/DC, low-pass filtering, diode testing and more
The kit is particularly useful for ATA Chapter-related tasks, including insulation testing of fuel control systems (ATA 73), fuel boost pumps (ATA 28) and APU systems (ATA 49).
Why This Kit Solves Real Problems for Aviation Professionals
Field technicians and MRO teams often face incomplete or fragile test kits that fail under real working conditions. The RBI9300TDR addresses this by combining a broad, aviation-focused selection of leads and instruments with a case that can withstand the environment. Whether you are performing routine insulation checks, diagnosing electrical issues or verifying system integrity, the kit reduces the need to assemble multiple separate tools and helps maintain consistency across jobs.
Key advantages at a glance:
- 68-piece selection covering both general and avionic-specific test requirements
- Rugged, waterproof and buoyant polypropylene case for genuine field durability
- Includes Fluke 1587 insulation multimeter tailored for aircraft electrical work
- Supports critical ATA chapter insulation and measurement tasks
- Organised drawer-style layout for fast access and reduced tool loss
