ST Engineering Aerospace Services Co

We specialise in airframe heavy maintenance and aircraft modifications at our two hangars in Singapore.

Leading the Charge in Aircraft Maintenance


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

We are a Centre of Excellence for Boeing 747, 777, 767, DC–10 and MD–11 aircraft. In 2007, we were conferred the Boeing Performance Excellence Award in the 767–300BCF Passenger-To-Freighter (PTF) conversion programme.

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

With all-encompassing maintenance and modification capabilities, we perform aircraft maintenance and aircraft modification work on the following aircraft types:

  • Boeing 737, 747, 757, 767, 777, 787
  • Airbus A300, A310, A320, A330, A340
  • DC-10, MD-10, MD-11

  • Value Added Services

    We have developed an e-CRM (Customer Relations Management) web-based platform so our customers can get real-time information on the status of their aircraft undergoing maintenance. This information can be accessed through a secure Internet connection. 

    Customers can get access to the 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.

  • Total Commitment to Quality Aircraft Engineering

    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.

    ST Engineering Aerospace Services Co is approved as a repair station by CAAS, EASA, FAA, the Japanese Civil Aviation Bureau (JCAB), the Australia Civil Aviation Safety Authority (CASA) and other airworthiness authorities.
