ST Aerospace Services Co

Having evolved to become a Centre of Excellence for Boeing 747, 777, 767, DC-10 and MD-11 aircraft, ST Aerospace Services Company was conferred the Boeing Performance Excellence Award (2007) in the 767-300BCF Passenger-To-Freighter (PTF) conversion programme.

Leading the Charge in Aircraft Maintenance

We specialise in airframe heavy maintenance and aircraft modifications, including passenger-to-freighter conversions, cabin upgrades, IFE upgrades, winglet modifications and fleet standardisation programmes.

From modest beginnings in 1990 with just a single wide-body aircraft hangar bay, we have expanded our facilities at Paya Lebar and Changi to accommodate up to nine wide-body aircraft and two narrow-body aircraft.

Our purpose-built hangar facilities are equipped with integrated docking systems to allow for aircraft heavy maintenance and aircraft modification works.

  • Boeing 737, 747, 757, 767, 777, 787

  • Value Added Services

    To facilitate quick dissemination of realtime information on the status of aircraft undergoing maintenance, and to allow this information to be accessed through a secure connection anywhere, anytime, we have developed an e-CRM (Customer Relations Management) web-based platform.

    This internet-based programme encompasses a series of specially tailored websites, providing customers with convenient access to detailed status of aircraft maintenance progress, materials usage and aircraft schedule.

    To complement the e-CRM platform, we have also developed the Aerobook tool that provides workers on the shop floor with direct access to aircraft maintenance documentation and allows the mechanic to raise inspection findings and material requisitions electronically.

    All these features translate into improved process efficiency and reduced aircraft downtime, leading to lower aircraft maintenance cost for our customers.

    We are committed to quality aircraft engineering.

    Our inspectors are fully licensed by the Civil Aviation Authority of Singapore (CAAS), the US Federal Aviation Administration (FAA), and the European Aviation Safety Agency (EASA).

    Random and in-process regular audits are conducted by our quality assurance department to ensure that all aircraft are serviced according to airworthiness requirements and standards.
