Maintainability is improved with modular, replaceable cabling.

Sikorsky submitted the S-70 design for the United States Army's Utility Tactical Transport Aircraft System (UTTAS) competition in 1972. The Army designated the prototype as the YUH-60A and selected the Black Hawk as the winner of the program in 1976, after a fly-off competition with the Boeing Vertol YUH-61. Self-sealing, crash-capable fuel tanks were chosen to limit the threat posed by small-arms fire or hard landings. The tail rotor blades incorporated into the new design were made of ballistically resilient materials to minimize the chance of a tail hit, which would compromise control of the rotorcraft. The main rotors saw a similar treatment, and an armored cockpit was added as the helicopter began to take shape. Redundant systems were worked into the designs of the flight controls, hydraulics, and electrical system to incr...
