Honeywell T53 family
Lycoming-origin, Honeywell-supported T53/LTC1 free-turbine turboshaft family. FAA records identify T53-L-9, T53-L-11, T53-L-13B/D, and T53-L-703 series engines on Bell AH-1 and UH-1 helicopters, alongside T5309/T5311/T5313B/T5317 variants on Bell 204/205 and Kaman K-1200 platforms. The family-level record preserves the historical Lycoming-to-Honeywell boundary and current product stewardship; exact dash variants and vehicle installations remain separate records.
