BUKZ-400

BUKZ-400 — verified identity and purpose

BUKZ-400 is a flap and slat control and monitoring unit. BUKZ-400 provides remote follow-up control and monitoring of two standard flap and slat channels. It commands hydraulic pressure and retraction valves, removes commands with or without a time delay, controls anti-retraction brakes and supplies signals to the test connector and onboard automated monitoring system. The unit is documented in the An-74 flight-control chain.

Function in the installed system

The block must be treated as one element of an installed aircraft system, working with the sensors, command circuits, indicators, actuators or power sources stated in that system documentation. A category label alone does not define pinout or interchangeability. General context is available under aircraft and avionics equipment.

Technical data and system interfaces

The Technical Details below separate confirmed values from points that still require the exact passport. Existing technical values were retained where they were specific to this designation. No voltage, aircraft type, mass or compatibility was copied from a similarly named product.

Identification and compatibility

Confirm the complete designation, suffix, series, drawing number, connector keying and aircraft or system effectivity. Related variants are not automatic substitutes. Photographs of the data plate and connectors are required when the execution cannot be established from the order line alone.

Inspection and ordering

Inspect the housing, mounting points, connectors, seals and markings before testing. Use only the approved procedure for the exact execution. State the full designation, aircraft or system, quantity, condition, delivery set and document requirements in the enquiry. Related items are listed under Electronic Control Units.
