Sabreliner 65 RVSM package in the works

A St. Louis-area maintenance facility is finalizing flight-test data required to support a Sabreliner 65 reduced vertical separation minimum (RVSM) compliance package. Avmats of Chesterfield, Mo., expects to receive group certification in October for Sabre 65s. The RVSM package includes replacement of the jet’s Collins ADC-80K air-data computer with new dual Collins ADC-87A air-data computers. The installation is expected to cost less than $140,000, said Avmats, or about $50,000 less than the OEM RVSM package for Sabre 65s (AIN, February, page 8).
