With temporary fuel-tank exemption, Longitude clears a key certification hurdle

摘要

The FAA has given Textron Aviation a temporary reprieve from requirements surrounding fuel tank flammability requirements in a partial exemption approval that clears a significant hurdle for certification of its new top-of-the-line Cessna Citation Longitude. With the August 16 time-limited approval in hand, Textron Aviation continues to eye a third-quarter approval of the super-midsize jet, designated the Model 700. But the exemption is applicable only through Jan. 31, 2020, and Textron Aviation must submit a compliance plan by October 1.
