At MRO Asia-Pacific 2023, Honeywell and Asia Pacific Aircraft Component Services (APACS), a subsidiary of SIA Engineering Company (SIAEC) and joint venture with SR Technics Switzerland, reaffirmed their long-term partnership with the announcement of additional Honeywell licences awarded to APACS. These licenses enable APACS to perform repair activities on Honeywell’s Air Data Inertial Reference Unit (ADIRU) and Pre-Cooler Control Valve (PCCV) products and to explore associated material supply opportunities.
The first license encompasses a ten-year programme, allowing APACS to perform repairs on Honeywell ADIRU products for Airbus aircraft. This complements the license granted to APACS last year for Honeywell ADIRU products for Boeing aircraft. The second license is a seven-year repair and material supply programme, which enables APACS to perform repair activities for Honeywell PCCV products utilised in Boeing 737 aircraft. Both of these programmes also enable both parties to explore sales opportunities for spare parts across various aircraft types.
The ADIRU is a key component of the integrated Air Data Inertial Reference System (ADIRS), which supplies air data (airspeed, angle of attack and altitude) and inertial reference (position and attitude) information to the pilots’ electronic flight instrument system displays as well as other systems such as the engines, autopilot, aircraft flight control system and landing gear systems. The PCCV controls the amount of fan cooling air that flows through the pre-cooler, resulting in a controlled bleed air outlet temperature.
