AIT Hold-Open Devices

Secure Cowl Support Across A320 and A340 Fleets

The AIT family standardizes hold-open tooling for fan cowl and thrust reverser access during engine removal and installation. Coverage includes Airbus A318/A319/A320/A321 with CFM56-5A/-5B and V2500, plus A340-200/-300 with CFM56-5C and A340-500/-600 with Trent 500. Families are supplied as bolted or welded versions to align with operator procedures. Each kit specifies left- and right-hand braces with turnbuckles; select models include a storage box for flight-line staging.

Keyfeatures

Family Architecture – Paired LH/RH braces with turnbuckles hold cowls open for controlled engine access.

Procedure-Matched Versions – Bolted and welded configurations align to approved maintenance methods on specified airframes.

Fan Cowl & Thrust Reverser – Model variants support either fan cowls or thrust reversers as required.

Engine/Airframe Mapping – Clear applicability lists ensure correct device selection by aircraft and engine type.

Kit Readiness – Defined contents and optional storage boxes streamline setup and staging at the aircraft.

Highlights

Unified hold-open solutions for A320-family and A340 cowl access—consistent, repeatable support during engine change.

Configuration Options

Safety & Operation

Use the designated device for the specific fan cowl or thrust reverser operation.

Install LH and RH braces with two turnbuckles per the kit procedure before engine-change tasks.

Apply only to the listed aircraft and engine combinations to maintain correct geometry.

Follow the supplied setup steps to keep cowls secured throughout removal and installation.

Store and handle components so alignment and brace lengths remain as configured.

Mobility & Transport

Select models include a storage box to protect and stage components at the flight line.

Brace and turnbuckle sets ship as discrete items for straightforward handling in hangars and on ramps.

Compact kit format allows easy movement between bays and aircraft stands.

Durability & Corrosion Protection

Welded or bolted constructions provide robust support consistent with the specified procedure.

Storage boxes help protect brace hardware and threads between uses.

Simple mechanical assemblies facilitate inspection and servicing routines.

Why RH Aero?

Standardized Access—Safer Changeovers

AIT delivers a coherent family of hold-open devices mapped to aircraft, engine, and cowl type for predictable operations. Procedure-matched versions, defined kit contents, and organized staging reduce variability and risk at the aircraft. Crews gain consistent setup, repeatable control, and efficient access during engine change and inspection tasks.
