In the now obsolete aircraft that I once worked on category, the BAC 1-11 was produced in small numbers (244) by British Aircraft Corporation from 1963–1982 in the UK, and later until 1989 in Romania.
Dee Howard Company, known for its head-of-state mods and thrust reversers, embarked on a project to re-engine the BAC 1-11 with Rolls Royce Tay engines. A collaboration between Schwartz Engineering Company, Dee Howard, and Avionics Engineering Services, the San Antonio based aircraft underwent interior modifications, an electrical system retrofit, and an instrument panel re-design. By April 1997, Alenia of Italy had taken over Dee Howard Inc. and withdrew backing of the Tay engined BAC 1-11 at a fairly late stage in the certification program.
I would later work on other BAC 1-11 aircraft for Chrysler Corporation—an interior project for Pyka Design. Then a BAC 1-11-400 for H&M Holdings Ltd. underwent antenna installations, and instrument panel and avionics rack re-designs. On a third BAC 1-11, operated by Lukenbill Enterprises and Gary Aerospace of Hondo, Texas for transport of the Sacramento Kings basketball team, I worked with the design team on interior modifications and installations.
Among the now decommissioned places that I worked at are British Aerospace Aviation Services Filton in Bristol, England. The manufacture of aeroplanes started here in 1910, and the Concorde called Bristol home prior to closure of the airport in 2012.
Our team provided engineering analysis and structural substantiation to GECAS (GE Capital Aviation Services) on Airbus A300 modifications and interior components for charter operations.
