context_page_description: Romaero, formerly Intreprinderea de Reparatii Material Aeronautic or IRMA, is a Romanian aerospace company, headquartered in Bucharest. In recent years, it has largely concentrated on aircraft repairs as well as component manufacturing for overseas companies.
  The company was founded by Royal Decree in 1920 under the name ASAM. It was rebranded as IRMA during 1944. In 1978, the company again changed its name to IAvB - Întreprinderea de Avioane București. Finally, it was rebranded as Romaero S.A. in 1991. Perhaps its largest manufacturing programme that the company has been involved in was mass production of the British-designed Britten-Norman Islander; over 500 airframes were reportedly completed in Romania. Another major independent undertaking of the firm was the Rombac 1-11 airliner, a license-produced model of the BAC One-Eleven produced in Romania; however, sales never reached expectations and the programme was abandoned during the late 1990s.
context_section_description: On 9 June 1979, Romanian president Nicolae Ceauşescu signed an agreement with the British Aerospace for the licensed production of the BAC One-Eleven in Romania. This was to involve the delivery of three complete One-Elevens (two 500-series aircraft and one 475 series) plus the construction of at least 22 in Bucharest, with reducing British content. It also involved Romanian production of Spey engines and certification of the aircraft to British standards by the Civil Aviation Authority. A market for up to 80 Romanian-built airliners was projected, largely in China and other developing economies, as well as Eastern Europe. The aircraft was re-designated Rombac 1-11.
  The first Rombac One-Eleven, (YR-BRA cn 401) a series 561RC, was rolled out at Romaero's Băneasa factory on 27 August 1982 and first flew on 18 September 1982. Production continued until 1989 at a much slower pace than had been previously foreseen. Nine aircraft were delivered, while the tenth and eleventh airliners on the production line being abandoned when they were 85% and 70% complete respectively. The first Rombac was delivered to TAROM on 29 December 1982. The Romanian carrier took delivery of all but two of the airliners produced, the remaining two going to Romavia, the last of which (YR-BRI cn 409) was delivered on 1 January 1993. Romania's economy and international position deteriorated to the point where supplies for One-Eleven manufacturing slowed to a trickle, with hard currency restrictions delaying overseas  component deliveries; the market foreseen had largely lacked interest, though some Rombac airliners were leased to European operators. The One-Eleven's noise level and fuel economy failed to keep pace with US and West European competition.
  Following the fall of the Ceauşescu regime, plans were made to restart production using the Rolls-Royce Tay. British aircraft leasing company Associated Aerospace agreed a $1 billion deal to purchase 50 Tay-powered One-Elevens fitted with a new electronic glass cockpit for onward leasing to Western customers; however, the liquidation of Associated Aerospace in April 1991 ended this deal. Efforts to sell the One-Eleven continued through the 1990s. In 1993, with US operator Kiwi International Air Lines placing a firm order for 11 Tay-engined aircraft with options for an additional five, but this plan fell through. In April 1997, Romaero announced was abandoning efforts to launch its envisioned revamp of the One-Eleven, which it referred to as the Airstar 2500.
