FOTRIC H4mini Acoustic Imaging Camera
Compact Acoustic Imaging — Find Leaks in Seconds
The FOTRIC H4mini is a lightweight, handheld acoustic imaging camera engineered to visualize ultrasonic sound the human ear cannot hear. With a 112 MEMS digital microphone array, a 13 MP industrial camera, and a real-time 3.5" IPS touch display, the H4mini pinpoints compressed air leaks, vacuum system losses, tire leaks, and abnormal vibration from loose components without shutting down the equipment. At just 770 g and rated IP54, it is built for fast, one-handed inspections across MRO floors, hangars, and flight-line operations.
Boeing Tool Coverage
Purpose-built for COM-18702
The FOTRIC H4mini meets or exceeds the technical specification called out by Boeing tool tag COM-18702 for handheld acoustic imaging — 112 MEMS digital microphones, 2 – 100 kHz range (COM-18702 requires 2 – 50 kHz), and IP54 rugged form factor. Marketed as a form-fit-functional equivalent under airline tool-equivalency programs.
Boeing AMM Tasks That Reference COM-18702
- Task 20-10-79-270-801Ultrasonic Leak Detection Checks — pairs with SPL-1473 for cabin pressurization, A/C, bleed air, hydraulic bypass, parking brake, pitot-static, oxygen, and pressurized-component leaks (Boeing 737-600 AMM EGN, applicability EGN ALL)
- Task GeneralWide-area acoustic scanning where an adjustable-frequency (2 – 50 kHz) digital acoustic camera is called out by the AMM in lieu of a handheld probe
Task references sourced from Boeing AMM documentation supplied by our customers. Coverage of individual tail-numbers depends on the operator's minor-model / revision applicability.
Tool Equivalency Statement
The FOTRIC H4mini is offered as an approved-equivalent alternative under airline tool-equivalency programs. It satisfies the acoustic sensing, frequency-range, and form-factor requirements referenced in Boeing tool tag COM-18702 for AMM ultrasonic leak-detection tasks. Adoption requires the operator's own Part 145 tool-equivalency documentation and quality-organization sign-off.
Regulatory Framework
- FAA 14 CFR 145.109(c)
- FAR 43.13(a)
- FAA Part 145
Boeing does not certify third-party alternatives. Tool tags are capability specifications; operators and Part 145 repair stations accept form-fit-functional equivalents through documented tool-equivalency programs. Consult your quality organization before adoption on any specific fleet.
