Type Certificate No. 299, issued March 21, 1958; Models 514/8 and 514/8A added June 23, 1969; Model 531/8 and 531/8B added October 3, 1960; Models 504/5A, 504/6A, 504/7A, 503/5A 503/6A, 503/7A, 502/5A, 502/6A, and 502/7A added February 4, 1963; Models 514/5, 514/5A, 514/6, 514/6A, 514/7, 514/7A, added March 4, 1976. Date of Application for Type Certificate: August 22, 1956. The aviation authority for the United Kingdom, the UK Civil Aviation Authority (CAA), originally type certificated this engine. The FAA validated this product under U.S. Type Certificate Number E-299. Effective September 28, 2003, the European Aviation Safety Agency (EASA) began oversight of this product on behalf of the UK. Import Requirements To be considered eligib le for installation on U.S. registered airc raft, each new engine to be exported to the United States with UK CAA or EASA airworthin ess approval shall have a Joint Aviation Authorities (JAA) or EASA Form 1, Authorized Release Certificate. The JAA or EASA Form 1 should state that the engine conforms to the type design approved under the U.S. Type Certificate E-299, is in a condition for safe operation and has undergone a final operational check. NOTE 1. The ratings of 502, 503, and 504 e ngines are based on standard conditions of temperature and barometric pressure 59°F and 29.92 in.Hg. at sea level and .012 absolute humidity. (.57 in.Hg. vapor pressure). If corrected to dry standard air conditions the maximum continuous powers at sea level would be increased by approximately 3.5% and 2.0%, respectively. The power output of different engines is based on a possible variation of ± 4% in accordance with British standards. NOTE 2.
