Taking advantage of years of customer feedback and design improvements for the original SkyStep series, the new Mustang SkyStep is a substantial upgrade from the original factory cabin step. Boasting a sleek, organic design, the new step is precision crafted from robust, lightweight aircraft aluminum. This makes for a tough, yet attractive design that will enhance the aircraft’s ramp appeal while improving safety and accessibility for pilots and passengers alike.

STC #SA04747NY is applicable to all variations of the Cessna Citation C510 Mustang business jet series.

We now offer the latest refinement of Sierra’s popular SkyStep cabin door modification. SkyStep’s innovative design and robust, lightweight construction eliminates the shortcomings of the original factory step. Improve passenger safety and convenience while enhancing your aircraft’s appearance.

SkyStep is approved for the following Cessna Citation models:

  • Citation 525 (CJ, CJ1, CJ1+)
  • Citation 525A (CJ2, CJ2+)
  • Citation 525B (CJ3, CJ3+)
  • Citation 500 / 501SP
  • Citation 550 / 551SP
  • Citation S550
  • Citation 560 (V, Ultra and Encore)
  • Enclosed back & sides prevents slips and improves passenger security.

  • 3 equally spaced steps instead of 2 for enhanced ease of entry.

  • First step is closer to the ground – no need for a separate “1st step” in the nose.

  • A pneumatic strut helps gently deploy the SkyStep, preventing damage to door sill and toes.

  • Precision machined from aircraft aluminum to eliminate cracking and breaking.
  • Mobile installation service is available — call us for details.

  • Easy field installation in less than 2 hours.
