FREIGHTER CONVERSION SUPPLEMENT ~ The sky’s the limit for ST Aerospace’s conversion business

In a relatively short period of time Singapore’s ST Aerospace (ST Aero) has become a major player in the aircraft modification business, and now counts engineering and development work, including modifications as contributing nearly a third of its revenue. Singapore-based ST Aero first commenced the B757-200 passenger-to-freighter (PTF) conversionprogramme just over three years ago.

In 2004 Boeing licensed both ST Aero and Israel Aerospace Industries (IAI) to jointly develop the Supplementary Type Certificate (STC) for the B757-200.

At the end of 2006, IAI decided it would no longer continue to participate in the programme and ST Aero went on to manage the programme and the engineering development of the STC, which it had been responsible for from the onset.

Since being licensed by Boeing in 2004, ST Aerospace (through its subsidiary, ST Mobile Aerospace Engineering, Inc (MAE), which is also the applicant and owner of the STC), has gone on solely to develop, undertake and manage the Royal New Zealand Air Force (RNZAF) multi-role configuration conversion programme and the 15-pallet STC programme.

The Singapore company is currently working on the conversion of two of RNZAF’s 757-200 aircraft. The contract with RNZAF is worth a total of US$38 million, and the first aircraft is expected to be redelivered in the fourth quarter 2007 while the second aircraft is expected to be inducted in late 2007 and redelivered in March 2008.
