Abstract:

The Preliminary Airworthiness Evaluation of the AH-1S Modernized Cobra, SN 69-16423 with the Kellett ferry tanks installed was conducted at Edwards Air Force Base, California 2302 feet and Bakersfield, California 488 feet. Approximately 19 productive hours were flown during 24 flights between 17 March and 27 April 1984. The Kellett ferry tanks increased the equivalent flat plate area by 2.0 sq ft. One deficiency noted during the evaluation was the lack of crashworthiness of the external fuel tanks. Four shortcomings associated with the installation of the external fuel tanks were found.
