Plain English Summary

1/10 complexity

This Airworthiness Directive requires owners/operators of Cessna 500/501 Citation jets (serials 0001–0676) fitted with H.T.L. nitrogen bottles (P/N 9912103-3) to perform a one‑time inspection of the bottle operating lever per Cessna Service Letter SL32‑36 before next flight after 31 July 1984. It ensures sufficient clearance so the lever can be operated in an emergency; without it the nitrogen system may be un‑activatable, risking catastrophic failure.
